ABSTRACT:
A drum-type washing machine includes a horizontal shaft type drum which is rotatably supported by a supporting shaft within a frame and rotated by a motor, and a reduction mechanism transmits a rotation of a rotation shaft of the motor to a rotation shaft of the drum. The reduction mechanism includes a small pulley with gear secured to the rotation shaft of the motor, an intermediate large pulley, a V belt wound on the small pulley with gear and the intermediate large pulley, an intermediate small pulley secured to the intermediate large pulley to be rotated together with the intermediate large pulley, a large pulley secured to the rotation shaft of the drum, and a V belt wound on the intermediate small pulley and the large pulley. In the vicinity of the small pulley with gear, a claw which is normally biased toward a direction that the same is kept away from the gear is arranged. A solenoid or a torque motor engages the claw with a root of the gear against the spring when the drum is to be locked.
