 wherein the casing comprises a body made of plastic and formed in a hexahedral shape having a predetermined thickness and comprising two side surfaces connected to upper and lower surfaces thereof and open front and rear surfaces, and the at least one space support tray provided on an inner side surface of the body in a height direction and a caster support portion to which each of the casters is mounted are integrally formed with the body when the body is formed,   wherein the space support tray comprises   a) a first support surface extending to inner sides of the two side surfaces of the body in the storage space and a cavity portion integrally formed therein so as to be connected to outer sides of the two side surfaces, and   b) a first round portion formed in at least one side of the first support surface,   wherein the caster support portion   a) is integrally formed with the body so as to protrude inward or outward from the body when the body is formed,   b) comprises a fixing section through which a bolt hole having a section having a predetermined depth and a predetermined thickness is formed, and   c) is configured to allow a caster having a brake to be fixed thereto,   wherein the caster   a) comprises a fixing boss supported by the body via a coupling member and a drive wheel mounted to the fixing boss so as to be freely rotatable,   b) is configured such that a positioning projection is provided on one side of the fixing boss and is supported in a positioning hole formed in one side of the bolt hole, and   c) further comprises a guide ring made of metal and supported on an outer diameter portion of the fixing boss to prevent friction between the fixing boss and the bolt hole, and   wherein the body is mounted so as to be movable horizontally and to enable storage and withdrawal of articles without falling of the articles by opening a door in a stopped state.   
     
     
         2 . The multi-purpose casing having a heavy-article support tray integrally formed therewith according to  claim 1 , wherein the space support tray having the cavity portion is integrally formed with the body when the body is formed using a combination of an X-axis mold and a Y-axis mold entering in a direction intersecting the X-axis mold, and
 wherein, when the body is formed, the caster support portion is integrally formed by a combination of the X-axis mold and a Z-axis mold.   
     
     
         3 . The multi-purpose casing having a heavy-article support tray integrally formed therewith according to  claim 1 , further comprising a support base integrally formed with the upper surface or the lower surface of the body,
 wherein the support base comprises a second support surface integrally extending from the body so as to protrude toward the storage space, and   wherein a second round portion corresponding to a bowling ball is formed in the second support surface.   
     
     
         4 . The multi-purpose casing having a heavy-article support tray integrally formed therewith according to  claim 1 , further comprising a handle support portion integrally formed with one of the two side surfaces of the body or at least one surface among the upper and lower surfaces of the body when the body is formed,
 wherein, when the body is formed, the handle support portion is integrally formed by a combination of a Y-axis mold having a bracket forming hole and an X-axis mold entering in a direction intersecting the Y-axis mold and having a protruding portion corresponding to the bracket forming hole or   a combination of the Y-axis mold having the bracket forming hole, the X-axis mold entering in a direction intersecting the Y-axis mold and having the protruding portion corresponding to the bracket forming hole, and a Z-axis mold having a Z-axis protrusion penetrating the body.   
     
     
         5 . The multi-purpose casing having a heavy-article support tray integrally formed therewith according to  claim 1 , further comprising a third support surface having a third round portion to support one side of a bowling ball and formed on at least one surface among the two side surfaces of the body so as to protrude inward,
 wherein the third support surface is integrally formed with the body by an X-axis mold when the body is formed, or   is manufactured as a piece separately from the body and is assembled to the body.   
     
     
         6 . The multi-purpose casing having a heavy-article support tray integrally formed therewith according to  claim 1 , further comprising a movement prevention member integrally formed with at least one selected from among the space support tray, the support base, and the third support surface,
 wherein the movement prevention member is implemented as at least one selected from among a tension portion comprising a cut portion formed in one side of the support surface so as to be elastically supported and a protrusion formed on an upper portion thereof, and   a support belt mounted on one side of a ball support to prevent separation of a bowling ball and formed so as to be fastened and released.   
     
     
         7 . The multi-purpose casing having a heavy-article support tray integrally formed therewith according to  claim 1 , wherein the body is provided with a handle support portion integrally formed therewith when the body is formed,
 wherein a handle mounted to the handle support portion has a telescopic structure and is tightly coupled to a receiving hole formed through the upper surface and the lower surface of the body via a fixing cap,   wherein the receiving hole is formed to be reduced in diameter downward to press a lower side of the fixing cap inserted thereinto, and   wherein a piece coupling portion is integrally formed with one side of the fixing cap to fix the handle to the body when the piece coupling portion is coupled as a piece to one side of the receiving hole.   
     
     
         8 . The multi-purpose casing having a heavy-article support tray integrally formed therewith according to  claim 1 , wherein the body is further provided with a door connected to an open portion to open and close the open portion, and
 wherein the door has a pocket provided in an outer side or an inner side thereof, is made of fabric or plastic, and is connected so as to be opened and closed by means of a zipper, a hinge, or a snap button.   
     
     
         9 . The multi-purpose casing having a heavy-article support tray integrally formed therewith according to  claim 1 , wherein the body is further provided with an auxiliary bag placed and supported on an upper side of the body while allowing a handle to pass therethrough, and
 wherein a holder made of fabric or plastic and having a mounting hole formed therein to allow the handle to be inserted therethrough in the vertical direction is integrally formed with the auxiliary bag, or is sewn to the auxiliary bag.
