An automatic washing machine includes a coiled clutch spring would about both tub and drive shafts so as to be tightly wound up about the tub shaft and wound up with rotation of the drive shaft to transmit rotation of the drive shaft to the tub shaft, an inner cylindrical member disposed so as to enclose the clutch spring and having an engagement portion engaging one end of the clutch spring at the drive shaft side, an outer cylindrical member having a large number of engagement claws formed on the outer periphery and fitted in with the inner cylindrical member so as to be rotatable with a predetermined frictional resistance against the inner cylindrical member. When the clutch spring is loosened a predetermined amount in the rotative movement in its loosening direction against the braking force of a brake mechanism applied to the tube shaft, the other end of the clutch spring strikes against the stopper. Subsequently, the stopper causes the inner cylindrical member to rotatively move relative to the outer cylindrical member against the frictional resistance upon movement of the other end of the clutch spring. |
