Claims

[Claims for Utility Model Registration] The bucking plate has a cylindrical shape with a large diameter part and a small diameter part, and an outer stepped surface formed between the large diameter part and the small diameter part. a guide member fixed to the bucking plate by inserting the small diameter part into the backing plate through the through hole and caulking the tip of the small diameter part until it abuts the peripheral edge of the through hole; An inner cable is inserted through the guide member and has one end attached to the parking brake lever provided inside the bucking plate, and an inner cable is provided on the outer circumferential side of the inner cable so as to be relatively movable in the axial direction, and one end is attached to the parking brake lever provided inside the bucking plate. A parking brake cable assembly for a drum brake, comprising an outer cable that is fitted into a guide member in a state where it is prevented from coming off, the cable assembly being provided at one end of the outer cable, and the one end of the outer cable being fitted into the guide member. When inserted a predetermined distance into the guide member from the large diameter part side, the inner stepped surface formed between the large diameter part and the small diameter part of the guide member directly or indirectly through another member. an abutting portion that abuts to prevent further insertion of the outer cable; and an abutting portion provided on the outer circumferential side of one end of the outer cable, the abutting portion of the outer cable directly or indirectly contacting the inner stepped surface. When inserted into the guide member while being elastically deformed until they come into contact with each other, the bucking plate passes through the through hole and engages with the peripheral edge of the through hole or the small diameter portion of the guide member. a plurality of elastically deformable engaging claws that prevent the outer cable from coming off the guide member; and a plurality of engaging claws that are elastically deformable to prevent the outer cable from coming off the guide member; A parking brake cable assembly for a drum brake, comprising: an elastic seal member that seals between the outer cable and the guide member when inserted into the guide member.
