摘要： PROBLEM TO BE SOLVED: To perform smooth interlock from an air chamber to a brake arm with high reliability by simple structure, and to easily assemble an automatic clearance regulation mechanism. SOLUTION: The mechanical lever type brake arm 3 is surely operated highly reliably by a combination of reduced components even by a relatively small air force via lever mechanisms 10, 11, 12, since the lever mechanisms pivoted to the other side end of a strut 7 moved by an air actuator 5 press a base end of the second brake arm 3, and since a brake operation is carried out by pad mechanisms 9, 8 attached to tip sides of the first and second brake arms 6, 3, and a brake operation force generating mechanism is simplified and an air calliper mechanism is reduced in side by this manner. Furthermore, the support structure of the brake arm is robust and vibration-proof strength is enhanced, since the brake arm 3 is journaled swingingly to a body housing 2 so as to secure sufficient strength.
