<p>PROBLEM TO BE SOLVED: To easily release the regulation of the retracting position of a parking lever by the smaller operating force than the conventional one, and to smoothly perform the shoe-returning action against the resistance by rust and earth. SOLUTION: A retraction regulating member is pivotably supported by a parking lever 6. A long plate part 18b which is elastically deformable in the direction orthogonal to a back plate is provided on the refraction regulating member, and the long plate part 18b is arranged on a web side surface of the parking lever 6 in the longitudinal direction. A serrated stopper part 18c which is once swollen in the web direction and folded back in the back plate direction is continuously provided on a tip of the long plate part 18b. The tip of the stopper part 18c is locked to an outside edge of the parking lever 6, and an inner edge of a web 4a of a brake shoe 4 is abutted on the stopper part 18c to regulate the turning of the parking lever 6 in the outward direction of the back plate.</p> |
