ABSTRACT:
The vacuum cleaner has a hollow first fixing member formed together with a body, and a second fixing member assembled with the first fixing member. The first and the second fixing members are formed with a first and a second ribs respectively. The first and the second ribs form a circular-shaped supporting rib part when the first and the second fixing members are assembled with each other. A rotational shaft of a wheel is inserted into the supporting rib part to be assembled therewith. Thus a port for fixing the wheel need not be formed on the body, and the air drawn into the body is not discharged through such a port. Further, since the rotational shaft does not protrude into the body, it is easier to install components in the body and to disassemble the wheel from the body.
