摩耗警報装置。A cam member number for expanding the brake shoe, a cam collar that contacts the shoe web and is slidably engaged in the axial direction, an adjustment bolt that is threadedly engaged with the cam member in the axial direction and pushes the cam collar, and an adjuster. An adjustment gear that is rotatably engaged with the bolt, a stopper lever that is engaged with the adjust gear to restrict the rotation of the cam member in the operating direction, and a lining that is rotatably provided with the cam member and has worn out more than a predetermined amount. In a mechanical drum brake having an automatic braking gap adjustment device comprising an adjustment lever that changes a meshing position with an adjustment gear, the stopper lever has a claw portion that engages with the adjustment gear;
It is provided with an engaging claw part that is in contact with the wall surface at an outer position of the claw part, and an opening that is inserted into the shaft part of the cam member, and when the stopper lever moves a predetermined amount, the retaining claw part is brought into contact with the wall surface. The stopper lever is rotated about this locking point to release the meshing relationship between the stopper lever and the adjustment gear, and an electrode is provided in the engagement recess. . A wear warning device for a mechanical drum brake, characterized in that wiring is connected to issue a warning with a lamp or a buzzer when the retaining pawl is locked in the engagement recess.
