Claims

[Claims for Utility Model Registration] A disk rotor, a slide pin protruding from a support member parallel to the axis of the disk rotor, and a guide hole penetrating in a direction parallel to the axis of the disk rotor. and a caliper supported by the support member so that the slide pin is slidably fitted into the guide hole so as to be movable in a direction parallel to the axis of the disk rotor. In a pin slide type disc brake in which the protruding end is located in the guide hole, the slide pin is provided in an opening of the guide hole on the protruding end side of the slide pin to close the opening and to reduce air pressure in the guide hole. A guide hole closing device that allows exhaust pressure in the guide hole when a predetermined value is exceeded, the device having a thin-walled cylindrical shape, and having the slide on the inner circumferential surface of the opening of the guide hole on the side from which the slide pin protrudes. an elastic member whose one end is caused to protrude from the open end of the guide hole by being fitted in a state where relative movement of the pin toward the base side is prevented; a bottomed cylindrical part; and an open end of the cylindrical part. an outward flange provided on the cylindrical portion, and a groove provided on the outer circumferential surface of the cylindrical portion and connected between the bottom side end surface of the cylindrical portion and the outward flange, and the cylindrical portion a lid member that is fitted into the opening of the guide hole so that the outward flange is brought into contact with the protruding edge of the elastic member; A guide hole closing device for a pin slide type disc brake, comprising: a stopper that prevents the lid member from being fitted in and restricts the contact state between the outward flange of the lid member and the protruding edge of the elastic member. .
