Abstract

A tip of a pneumatic brake cylinder device is attached rotatably at a base side of a caliper body, and a base end of a first brake lever is attached rotatably to an end part of a cylinder at a side opposite to where the rod protrudes. A center part of the first brake lever is rotatably attached to the body. A front part end of a second brake lever is rotatably attached to a tip of the body, and the base ends thereof come into contact with a tip of the first brake lever. A brake lining and a brake head are attached on an inner surface at a tip of a pressing-force transmission member disposed at a center part front part of the second brake lever. A torque-receiving pin tip is immobilized at the brake head, and a shaft is held on the body via a spherical washer.
