PROBLEM TO BE SOLVED: To provide a washing machine with a silent durable spin drier without reduction gear noise while washing. SOLUTION: By controlling motor revolution variably and reducing revolution speed with a pulley part, prescribed revolution per minute of revolution wings and a spin drier tub is secured. Simultaneously, by shifting a center line in thrusting direction of belt hanging face on outer periphery of the axis side of pulley to lower bearing side to the center line in thrust direction of a axis attachment part to an axis of revolution wings of the axis side of pulley, a radial load to the lower bearing supporting the revolution wings and an axis of the spin drier tub respectively by axis is reduced. Thereby, noise while washing is reduced without decreasing its durability.
