Claims (1)

[Claims for Utility Model Registration] 1. A washing and dehydration tank is provided which is used for both washing and dehydration, and the washing and dehydration tank is rotated by the power of a motor being transmitted through a shaft member during dehydration, and A washing machine in which the shaft member is held in a fixed state by restricting rotation of the shaft member during washing, includes a one-way brake means for restricting rotation of the shaft member in one predetermined direction during washing, and the one-way brake. The shaft member is equipped with a one-way clutch that allows rotation only in the direction regulated by the means and has a radial bearing function. A brake mechanism for a washing machine, characterized in that the brake mechanism is supported by the one-way clutch described above. 2. A washing and dehydration tank is provided which is used for both washing and dehydration, and the washing and dehydration tank rotates when the power of the motor is transmitted through a shaft member during dehydration, and when the shaft member rotates during washing. In a washing machine in which the shaft member is held in a fixed state by being regulated by a brake means, the above-mentioned brake means includes an annular convex portion having a wedge-shaped cross section formed on the outer periphery of the shaft member, and an annular convex portion formed on the outer periphery of the shaft member. a brake arm that is rotatably provided along the brake arm; a brake shoe that can come into contact with the upper and lower surfaces of the annular convex part; a biasing means that biases the brake arm to rotate in one of a direction away from the annular convex part or a direction in which it comes into contact with the annular convex part; 1. A brake mechanism for a washing machine, comprising a drive means for rotating a brake arm in a direction opposite to the direction of urging by the urging means, against the urging force of the urging means.
