Claims

[Claims for Utility Model Registration] A pair of brake shoes, an anchor, etc. are provided so as to protrude into the inside of the backing plate through an elongated part formed in the backing plate that supports the components of the drum brake, and at the inside end thereof. A mounting device for rotatably mounting a bell crank lever linked directly or indirectly to the brake shoe on the backing plate, wherein one steel plate is attached to a part of the side wall portion facing each other and the side wall. The backing is bent into a shape including a U-shaped portion, and the side wall portion is parallel to the longitudinal direction of the elongated hole, and the portion near the connecting portion is bent into a U-shaped portion. A member fixed to the inner surface of the plate, the member sprouting from each of the pair of side walls toward the outside of the backing plate, fitting into the elongated hole, and engaging with either end of the elongated hole. a pair of U-shaped notches formed in mutually opposing portions of the pair of side walls from an edge on the side of the pulling plate to an edge on the opposite side of the side walls; a bracket that spans between the side walls of the bracket in substantially contact with the bottoms of the pair of notches, and the outer circumferential surfaces of both ends projecting outward from the side walls are supported by the inner surface of the backing plate. and a pivot shaft that passes through an intermediate portion of the bell crank lever inserted between the side walls and rotatably supports the lever in a plane parallel to the side walls, and the pivot shaft is configured to actuate the parking brake. At times, a component of the force applied to the lever in the longitudinal direction of the elongated hole is applied to the bladder,
The force is received at one end of the elongated hole through the protrusion of the backing plate, while the component force directed toward the outside of the backing plate is received at the inner surface of the backing plate through the pivot shaft.
