装置。 A cam collar, which the free end of the shoe web comes into contact with, is slidably fitted in the cam shaft direction to the cam portion of the cam member that expands the brake shoe when the brake arm rotates, and an adjuster is inserted through the cam member. A braking system in which an adjustment gear is screwed onto the shaft of the bolt, and during braking, the adjustment bolt is screwed to move the adjustment bolt in the adjustment direction of the camshaft, and the brake shoe is expanded using a cam collar to adjust the braking gap. In a mechanical drum brake equipped with an automatic gap adjustment device, the adjusting bolt is made of a conductive material, and a viewing part and a contact part following the adjusting bolt are provided at the tip of the adjusting bolt, and the adjusting bolt is made of an insulating material that covers the adjusting gear. Place the covered cover,
The cover is provided with a terminal that comes into contact with the contact portion and activates an alarm when the adjusting bolt is screwed out by a predetermined amount, and a transparent window portion that allows the viewing portion of the adjusting bolt to be viewed. Lining wear warning device for mechanical drum brakes.
