Clearance adjustment devices 9a, 9b are arranged between these hydraulic pistons 7a, 7b. A base end part 13a of a brake lever 13 is rotatably arranged at an end part of a rod protruding side of a parking brake cylinder device 12 installed at the base end side of the caliper main body 2, and the brake element 8a at the side where the hydraulic pistons 7a, 7b are arranged is pushed by an extremity end part 13b around a fulcrum point 13c placed to the wheel side rather than a working oil pipe port 2a of the caliper main body 2.EFFECT: A size of the prior art float type caliper brake device can be maintained and its mounting characteristic onto a bogie is not prohibited.SELECTED DRAWING: Figure 1
