ユー間隙自動調節装置。[Claims for Utility Model Registration] A pair of brake shoes attached to a bucking plate and a star wheel that spans between the pair of brake shoes, with the pair of brake shoes attached to the inner peripheral side. a strut device that is supported by the star wheel and extends as the star wheel rotates; and a strut device that is rotatably attached to one of the pair of brake shoes by a rotary pin and rotated by the parking brake operating force. a parking lever that pushes one end of the strut device toward the other end when the strut device is turned; a movably provided adjustment member, and when the adjustment member is pushed by the parking lever and the amount of rotation thereof exceeds a predetermined amount of rotation, the claw portion of the adjustment member engages the strut device. In the drum brake shoe gap automatic adjustment device of the type in which the star wheel is rotated in a direction to extend the brake shoe, the parking lever and the adjustment member are mounted on opposite sides with one of the brake shoes sandwiched therebetween. Features an automatic shoe gap adjustment device for drum brakes.
