Claims

[Claims for Utility Model Registration] (1) A bucking plate, a rotating drum that faces the bucking plate and is provided so as to be relatively rotatable about an axis, and the rotating drum on the inner circumferential side of the rotating drum. a single brake shoe provided on the bucking plate so as to be able to approach and separate from the inner circumferential surface of the brake shoe; A drum brake device comprising: an input device for input; and a pair of anchor members fixed to the bucking plate and receiving braking torque based on contact with one end or the other end of the brake shoe. (2) The input device includes a parking brake lever which is rotatably provided at one end with a pin in the longitudinal center of the brake shoe and into which a parking brake operation force is input at the other end, and a parking brake lever which is rotatably provided at one end in the longitudinal center of the brake shoe and into which a parking brake operating force is input, and a contact portion that pushes the brake shoe toward the outer circumference by the pin as the parking brake lever rotates in the brake operation direction based on contact with an intermediate portion of the parking brake lever. A drum brake device according to claim 1, which is a utility model. (3) The input device is rotatably provided on the backing plate with an intermediate portion as a rotation center,
Utility model registration claim No. 1, which has a rotary member at one end of which is engaged with the central portion in the longitudinal direction of the brake shoe so as to be pressable in the outer circumferential direction, and at the other end to which a parking brake operating force is input. The drum brake device according to item 1.
