PROBLEM TO BE SOLVED: To simplify and facilitae the moving work even if the bath tub device gets heavier, or bigger to a medium size or a large size and cope with variety of purposes by providing wheels for enabling the movement of a bath tub, and a driving mechanism for driving in rotation the wheels. SOLUTION: Wheels 15 are provided near four corners of the base 13 of a cover 10, and the wheels 15 having a caster structure are fixed to the base 13 of the cover 10 by screwing or adhesion. An electric motor 18 as a driving mechanism for driving the wheels 15 in rotation is provided near one of the wheels 15. The electric motor 18 is driven by turning on a power switch 20, and the driving force is transmitted to the wheels 15 through a transmission mechanism to drive the wheels 15 in rotation, thereby moving a bath tub device. Thus, even if the bath tub device is increased in weight and enlarged to a medium size or a large size, the operation labor can be reduced so as to improve the mobility. |
