徴とするドラムブレーキ。[Scope of Claim for Utility Model Registration] (1) A back plate attached to a non-rotating part of a vehicle, a pair of brake shoes attached to the back plate so as to be expandable, and a pair of brake shoes attached to the rotating shaft side of the vehicle, A drum comprising: a brake drum that generates braking force when the brake shoe is expanded and pressed; and a parking lever that expands the brake shoe via a cable when the parking brake lever is operated. In the brake, a positioning part is provided at the connection part of the parking lever with the cable, the positioning part extending in the opposite direction to the direction in which the parking lever is rotated by being pulled by the cable, and having a bent tip and extending toward the back plate side; On the back plate,
A drum brake, characterized in that the parking lever is slidable during rotation, and further includes a stopper portion that the positioning portion comes into contact with to restrict the maximum rotational position of the parking lever. (2) A back plate attached to a non-rotating part of the vehicle, a pair of brake shoes attached to the back plate so as to be expandable, and a pair of brake shoes attached to the rotating shaft side of the vehicle so that the brake shoes can be expanded. A strut is interposed between the brake drum, which generates braking force by being pressed against the brake drum, and the pair of brake shoes, and a parking lever is pivotally supported on one of the brake shoes, and the parking lever is operated by the parking brake lever. A drum brake comprising: a parking brake section that generates braking force by expanding a brake shoe by rotating the parking lever via a cable; the brake of the one brake shoe of the parking lever; A positioning part is formed on the drum side, and a stopper part is formed on the back plate to which the parking lever comes into contact and regulates the maximum rotational position of the parking lever. A drum brake characterized by being located between the lever and the back plate.
