 a grip portion including a hinge portion that is rotatably coupled to the hinge shaft and extending from the hinge coupling portion. 
   
     
     
         2 . The cleaner of  claim 1 , wherein the handle is disposed on a rear side of the main body,
 wherein the hinge portion is located at an upper end portion of the grip portion, and   wherein a lower end portion of the grip portion is configured to rotate around the upper end portion of the grip portion.   
     
     
         3 . The cleaner of  claim 1 , wherein the hinge portion is inserted into the hinge coupling portion and rotatably coupled to the hinge shaft. 
     
     
         4 . The cleaner of  claim 3 , wherein the hinge coupling portion includes a first elastic portion that is configured to deform in proportion to a rotation of the hinge portion, and
 wherein the deformed first elastic portion is configured to exert, to the hinge portion, a restoring force.   
     
     
         5 . The cleaner of  claim 4 , wherein the hinge portion includes a pressing protrusion that protrudes in a direction away from the hinge shaft, that is configured to rotate with the hinge portion, and that is configured to press the first elastic portion, and
 wherein a change to an amount of the protrusion of the pressing protrusion toward the first elastic portion is based on the rotation of the hinge portion.   
     
     
         6 . The cleaner of  claim 5 , wherein the hinge coupling portion defines an elastic portion space extending in the direction away from the hinge shaft,
 wherein the first elastic portion includes a first spring disposed at the elastic portion space and extending parallel to the elastic portion space, and   wherein a length of the first spring varies based on the pressure applied by the pressing protrusion.   
     
     
         7 . The cleaner of  claim 6 , wherein the first elastic portion further includes a pressing plate that is coupled to an end of the first spring and that is configured to move along the elastic portion space based on a first space thereof facing the hinge portion being pressed by the pressing protrusion. 
     
     
         8 . The cleaner of  claim 6 , wherein the first elastic portion includes a second spring that is wound around the hinge shaft and that is deformed in proportion to a rotation of the grip portion. 
     
     
         9 . The cleaner of  claim 8 , wherein the hinge coupling portion further includes a first coupling protrusion that is disposed inside the hinge coupling portion and that is coupled to a first end of the second spring,
 wherein the hinge portion includes a second coupling protrusion that is configured to rotate with the hinge portion and that is coupled to a second end of the second spring.   
     
     
         10 . The cleaner of  claim 1 , wherein the handle further includes a sliding coupling portion that is disposed on the main body and that includes a sliding protrusion slidably coupled to the grip portion,
 wherein the grip portion further includes a sliding portion through which the sliding protrusion is slidably inserted, and   wherein the sliding protrusion is configured to slide in the sliding portion based on the grip portion being rotated around the hinge portion.   
     
     
         11 . The cleaner of  claim 10 , wherein the handle is disposed at a rear side of the main body,
 wherein the hinge portion is located at an upper end portion of the grip portion,   wherein the sliding portion is located at a lower end portion of the grip portion.   
     
     
         12 . The cleaner of  claim 11 , wherein the handle further includes a base disposed at the rear side of the main body,
 wherein the base provides (i) the hinge coupling portion at an upper portion thereof and (ii) the sliding coupling portion at a lower portion thereof, and   wherein the base further provides, between the hinge coupling portion and the sliding coupling portion, an indented portion that is indented forward to accommodate fingers of a user.   
     
     
         13 . The cleaner of  claim 10 , wherein the sliding protrusion is disposed inside the sliding coupling portion,
 wherein the sliding portion is inserted into the sliding coupling portion such that the sliding protrusion is slidably coupled to the sliding portion.   
     
     
         14 . The cleaner of  claim 13 , wherein the sliding portion defines a sliding space through which the sliding protrusion is inserted, and
 wherein a rotation range of the grip portion around the hinge portion is limited based on a moving range of the sliding protrusion being limited by an inner face of the sliding space.   
     
     
         15 . The cleaner of  claim 14 , wherein the sliding portion includes a second elastic portion that is positioned between the sliding protrusion and the inner face of the sliding space and that is elastically deformed by the sliding protrusion. 
     
     
         16 . The cleaner of  claim 10 , wherein the sliding portion defines a sliding hole or a sliding groove into which the sliding protrusion is inserted. 
     
     
         17 . The cleaner of  claim 16 , wherein a sliding range of the sliding protrusion corresponds to an extended length of the sliding hole or the sliding groove. 
     
     
         18 . The cleaner of  claim 1 , further comprising:
 a filter disposed inside the main body and configured to filter, based on the substance passing through the filter, the substance from air.   
     
     
         19 . The cleaner of  claim 18 , wherein the main body defines an outlet at a top surface, and
 wherein the air is discharged outside through the outlet.   
     
     
         20 . The cleaner of  claim 4 , wherein the restoring force is exerted to generate a pivoting force that causes the hinge portion to pivot in a pivoting direction opposite to a normal pivoting direction of the hinge portion.
