Vacuum cleaner

Abstract

A vacuum cleaner includes a main body case which includes a main body connection port at a front side, a pair of wheels provided on the left and right side portions of the main body case to support the main body case movably and conceals at least a back surface of the main body case when viewed in a rotation axis direction, and a secondary battery provided in an area sandwiched between the pair of wheels and arranged in conformity with the shape of the main body case.

1 . A vacuum cleaner comprising:
 a main body case which has a suction port at a front side of the main body case;   a pair of wheels which is provided on left and right side portions of the main body case to support the main body case movably and conceals at least a back surface of the main body case when viewed in a rotation axis direction; and   a secondary battery which is provided in an area sandwiched between the pair of wheels and arranged in conformity with a shape of the main body case.   
     
     
         2 . The vacuum cleaner according to  claim 1 , wherein
 the secondary battery has an arcuate shape which is centered substantially at a rotation axis of the pair of wheels.   
     
     
         3 . The vacuum cleaner according to  claim 1 , wherein
 a center of the arcuate shape of the secondary battery is arranged at a center of a dimension in a direction orthogonal to a center line of the main body case on a plane orthogonal to the rotation axis of the pair of wheels.   
     
     
         4 . The vacuum cleaner according to  claim 2 , wherein
 a center of the arcuate shape of the secondary battery is arranged at a center of a dimension in a direction orthogonal to a center line of the main body case on a plane orthogonal to the rotation axis of the pair of wheels.
