PROBLEM TO BE SOLVED: To provide a washing machine having less vibration and noise by making mounting angles between blades of a cooling fan non-uniform and arranging the blades so that the mounting angles between all the blades are different in the cooling fan of a motor for normally and reversely rotating a rotary vane of the washing machine.SOLUTION: A washing machine includes: an inner tub having a rotary vane at the bottom; an outer tub including the inner tub; an outer frame for accommodating the outer tub; a vibration-proof device for suspending and supporting the outer tub at the outer frame; a motor for rotating the rotary vane and the inner tub; and a cooling fan for cooling the motor. The washing machine is configured to make mounting angles between blades of the cooling fan of the motor non-uniform. The blades of the cooling fan are arranged so that the mounting angles between all the blades are different and all the angles in accordance with the mounting angles between three or more sheets of adjacent blades are different.SELECTED DRAWING: Figure 2 【課題】洗濯機の回転翼を正逆回転させるモータの冷却ファンにおいて、冷却ファンの羽根間の取り付け角度を不均一にし、そのすべての羽根間の取り付け角度が異なるように羽根を配置し、振動や騒音が少ない洗濯機を提供することにある。【解決手段】本発明は、底部に回転翼を有する内槽と、該内槽を内包する外槽と、該外槽を収納する外枠と、該外枠に前記外槽を懸架支持する防振装置と、前記回転翼および前記内槽を回転させるモータと、該モータを冷却するための冷却ファンを備え、前記モータの冷却ファンの羽根間の取り付け角度が不均一になるように構成する。そして、すべての羽根間の取り付け角度が異なっている、かつ、隣り合った３枚以上の羽根間の取り付け角度を合わせた角度も、すべて異なっているように冷却ファンの羽根を配置するように構成する。【選択図】 図２
