         4 . The cleaner according to  claim 3 , wherein
 the drive unit is arranged in a motor chamber of the main body housing,   the cleaner comprises a motor chamber cover that covers the motor chamber, and   the holding rib is sandwiched between the main body housing and the motor chamber cover.   
     
     
         5 . The cleaner according to  claim 4 , wherein
 the main body support portion has an oval cross section and includes a reinforcement rib provided in the opening at a central portion in the major axis direction of the main body support portion.   
     
     
         6 . The cleaner according to  claim 5 , wherein
 the first support member includes a drive unit support portion that supports the drive unit.   
     
     
         7 . The cleaner according to  claim 6 , wherein
 the main body support portion and the drive unit support portion are provided on each of one side and other side with respect to a rotation axis of the motor.   
     
     
         8 . The cleaner according to  claim 7 , wherein
 the first support member includes a coupling portion that couples the drive unit support portion provided on the one side and the drive unit support portion provided on the other side.   
     
     
         9 . The cleaner according to  claim 8 , wherein
 the drive unit includes a cooling fan that cools the motor, and   air flowing out of the cooling fan is discharged to an outside of the main body housing through the opening.   
     
     
         10 . The cleaner according to  claim 1 , further comprising
 a second support member mounted on at least a part of the drive unit and supported by the main body housing.   
     
     
         11 . The cleaner according to  claim 10 , wherein
 the second support member includes at least one support rib provided on an outer circumferential surface of the second support member.   
     
     
         12 . The cleaner according to  claim 11 , wherein
 the support rib extends in a direction parallel to a rotation axis of the motor, and   the main body housing has an arcuate rib that supports the support rib, and   the arcuate rib extends in a direction orthogonal to the support rib.   
     
     
         13 . The cleaner according to  claim 2 , wherein
 the main body support portion has an oval cross section and includes a reinforcement rib provided in the opening at a central portion in the major axis direction of the main body support portion.   
     
     
         14 . The cleaner according to  claim 1 , wherein
 the first support member includes a drive unit support portion that supports the drive unit.
