レーキ。a pair of first and second brake shoes that are expandably attached to the backing plate and pressed against the inner peripheral surface of the rotating drum; a pair of first and second brake shoes that are rotatably attached to the second brake shoe; , an adjustment member having engagement teeth formed approximately along an arc centered on the rotation center; the adjustment portion; a latching member provided on the first brake shoe and allowing rotation of the adjustment member in one direction but preventing rotation in the other direction; and a locking member disposed between the first brake shoe and the adjustment member; and a strut member operatively connecting the first brake shoe and the adjustment member, the first brake shoe and the second brake shoe When the separation amount when the brake shoes are expanded exceeds a predetermined certain amount, the rotational position of the adjusting member is changed to increase the operating gap between the pair of brake shoes and the rotating drum. In the drum brake that is automatically adjusted, the locking member is arranged such that the engagement positions of the engaging teeth of the adjusting member and the locking teeth of the locking member are shifted from each other within one pitch of the engaging teeth. in the state, a plurality of brake shoes are provided in the second brake shoe, and
1. A drum brake equipped with an automatic operating gap adjustment function, characterized in that springs are provided for biasing the latching teeth of the latching member in a direction in which the latching teeth of the latching member converge with the retaining teeth of the adjusting member.
