Claims (1)

[Scope of utility model registration request] A washing and dehydration tank in which a bottom pulsator is rotatably arranged in forward and reverse directions, a water tank containing the washing and dehydration tank, a dehydration shaft that supports the washing and dehydration tank so as to be rotatable in one direction, and a lower end of the dehydration shaft on the top. A rotation mechanism part is provided, which is made of a gear case plate, etc., which has a press-fitted cylindrical part and which is fixed to a brake drum in which a gear reduction device is installed, and the outer periphery of the brake drum has a strong braking force on the dehydration rotation side. In a dehydrating washing machine that is equipped with a band brake, a rotating mechanism section with the band brake is supported at the upper part by an upper lid body, and a bearing box is provided at the lower part to accommodate and support a lower housing. A clutch housing is provided in which the collar part is integrally formed with an annular protrusion projecting inward at the lower part of the inner circumferential surface, and a plurality of ratchet grooves are continuously formed on the inner circumferential surface, and a circular groove is formed in the groove. A bearing-like roller clutch that is capable of rotating a columnar roller, and a triangular housing that has an annular body with a generally groove-shaped cross section, an annular body that protrudes from the lower part of the inner peripheral surface, and a triangular protrusion that protrudes from the center. A dewatering shaft is constructed by installing a clutch oil seal by winding a spring around an inner depression of the protrusion, press-fitting the roller clutch into the upper part of the annular protrusion of the clutch housing, and press-fitting the clutch oil seal into the lower part. A dehydrating washing machine comprising a reversal prevention member, the dehydration shaft reversal prevention member being rotatably fitted to a cylindrical portion of the brake drum, and a collar portion being fixed to the upper lid.
