<p>PROBLEM TO BE SOLVED: To comparatively simplify the structure of the subject device, and further improve washing performance by transmitting the rotary motion of an electric motor to a second base section, and setting the diameter of the second base section to be smaller than the diameter of a first base section, and setting the length of a second bristle to be shorter than the length of a first bristle. SOLUTION: A second wiping means of this washing device 51 is constituted of a second base section 61b and a second bristle implanted on the second base section 61b, both of which present a cylindrical outer shape. Also, the raw material of the second base section 61b is the same as a first base section 60b. The diameter of the second base section 61b is smaller than that of the first base section 60b. Also, the second bristle is higher than a first one. Then, a rotary torque generated by an electric motor 70a is transmitted to the two second base sections 61b through a belt. Also, the transmission of the rotary torque from the first base section 60b to the second base section 61b, and the transmission of the rotary torque between the two second base section 61b, are performed with belts.</p> |
