Abstract: The washing machine of the present disclosure includes an improved pulley for reducing the noise generated in the pulley. When the shaft is inserted into the shaft insertion hole, at least a part of the shaft is closely contacted with the shaft insertion hole to minimize the tolerance between the shaft and the shaft insertion hole, and the rotation shaft of the pulley and the center axis of the shafts may be made to coincide with each other, so that the noise generated by the rotation of the pulley can be effectively reduced. In addition, the spoke of the pulley includes the curved portion, thereby reducing the friction with the air and effectively reducing noise due to friction with air.

Abstract: By improving the rigidity of a pulley while suppressing a weight of the pulley from increasing, excessive noises due to resonance can be reduced. A washing machine 1 includes a drum 9 rotatably disposed in the water tub 5. The washing machine 1 has a motor to rotationally drive a pulley 20, which is fixed to the drum 9, via an endless belt 13. The pulley 20 has a plurality of arms 23 radially extend from the boss 22 to support an outer wheel 21. The arm 23 has a variable cross-sectional portion 24 in which a section modulus against bending in an axial direction gradually decreases from the boss 22 to the outer wheel 21.

Abstract: A washing machine includes a damper to reduce a vibration. The damper includes a damper frame and a rod respectively supported by the tub and the housing. The rod may move relative to the damper frame in an axial direction by being inserted into a support portion of the damper frame. A rotation movement member is movable in the axial direction by rotating with respect to the damper frame. A friction member is disposed between the support portion and the rotation movement member and applies a friction force to the rod. A switching unit switches, by rotating the rotation movement member, the damper between a first state in which the friction member is movable together with the damper frame with respect to the rod and a second state in which the friction member is movable together with the rod with respect to the damper frame.
