       2 . The drum type washing machine of  claim 1 , wherein the bearing housing is formed as one body with the tub. 
   
   
       3 . The drum type washing machine of  claim 2 , wherein a hub is projected outwardly at a center of a rear surface of the tub. 
   
   
       4 . The drum type washing machine of  claim 3 , wherein the bearing housing is positioned at the tub, passing through the hub. 
   
   
       5 . The drum type washing machine of  claim 4 , wherein unevenness is formed on an outer circumferential surface of the bearing housing and an inner circumferential surface of the tub in a circumferential or extent direction, respectively. 
   
   
       6 . The drum type washing machine of  claim 1 , wherein the motor mounter is coupled to the tub, spaced apart a predetermined distance from the bearing housing in a radial direction. 
   
   
       7 . The drum type washing machine of  claim 6 , wherein the motor mounter is ring-shaped. 
   
   
       8 . The drum type washing machine of  claim 7 , wherein the motor mounter comprises,
 a ring-shaped plane part; and   a side surface projected perpendicularly toward the tub from the plane part.   
   
   
       9 . The drum type washing machine of  claim 8 , wherein the side surface is formed at on least one of an inner portion or an outer portion of the plane part with respect to a radial direction of the plane part. 
   
   
       10 . The drum type washing machine of  claim 7 , wherein a coupling part is formed at the stator, coupled to the tub and the motor mounter, and a coupling hole corresponding to the coupling part is formed at the motor mounter. 
   
   
       11 . The drum type washing machine of  claim 10 , wherein the motor mounter comprises a tub coupling hole coupled to the tub. 
   
   
       12 . The drum type washing machine of  claim 11 , wherein a seating part is formed at a rear surface of the tub and the motor mounter is seated on the seating part. 
   
   
       13 . The drum type washing machine of  claim 12 , wherein the seating part has a shape corresponding to the motor mounter. 
   
   
       14 . The drum type washing machine of  claim 7 , wherein the motor mounter comprises a plurality of reinforcement ribs that extend along a circumferential direction. 
   
   
       15 . The drum type washing machine of  claim 14 , wherein the motor mounter is formed of a steel plate, further wherein the reinforcing rib is formed by a lancing process. 
   
   
       16 . The drum type washing machine of  claim 6 , wherein the motor mounter is configured of a plurality of modules. 
   
   
       17 . The drum type washing machine of  claim 16 , wherein the plurality of the modules are connected each other. 
   
   
       18 . The drum type washing machine of  claim 6 , wherein at least a predetermined portion of the motor mounter is insert-molded in the tub. 
   
   
       19 . The drum type washing machine of  claim 18 , wherein an upper portion of the motor mounter is exposed when the motor mounter is insert-molded in the tub. 
   
   
       20 . The drum type washing machine of  claim 19 , wherein a coupling hole to which the stator is coupled is formed at the motor mounter and the motor mounter is insert-molded, the coupling hole being exposed outside the tub.
