成したことを特徴とするホイールシリンダ。 a cylinder body fixed to a bucking plate; a piston that is slidably inserted into an inner hole of the cylinder body and forms a hydraulic chamber into which pressure fluid from a master cylinder is supplied; The piston is disposed within the hydraulic pressure chamber so that one end surface is in contact with the hydraulic chamber side end surface of the piston, and slides integrally with the piston in a fluid-tight manner within the inner hole of the cylinder body by its outer peripheral lip. a cup seal made of a movable elastic material; a seat member disposed within the hydraulic chamber so that one end surface of the cup seal contacts an end surface on the hydraulic pressure chamber side; 1. A wheel cylinder comprising a spring that stably presses the piston at all times, characterized in that the cup seal and the seat member are integrally connected or constituted of one member.
