PROBLEM TO BE SOLVED: To provide a caliper brake device which inhibits deterioration of a fastening force between a guide plate and a piston.SOLUTION: A caliper brake device applies a friction force to a disc which rotates with a wheel to put a brake on the wheel and includes: a caliper body; a piston which is provided in the caliper body so as to move forward and rearward and moves forward and rearward according to a pressure in a pressure chamber of the caliper body; a brake shoe which slidably contacts with the disc to apply the friction force to the disc; a guide plate which supports the brake shoe and is attached to the piston; and a fastening member which fastens the piston to the guide plate. The piston has a tapered contact part. The fastening member comprises: a bolt having a screw shaft; a nut which threadedly engages with the screw shaft; a washer positioned between the nut and the piston and having a tapered nut side seating surface which contacts with a contact part of the piston; and a disc spring provided between the nut and the washer.SELECTED DRAWING: Figure 3

    【課題】ガイドプレートとピストンの締結力の低下を抑制可能なキャリパブレーキ装置を提供する。【解決手段】キャリパブレーキ装置は、車輪とともに回転するディスクに摩擦力を付与することで車輪を制動するキャリパブレーキ装置であって、キャリパ本体と、キャリパ本体に進退自在に設けられ、キャリパ本体の圧力室内の圧力に応じて進退するピストンと、ディスクに摺接することでディスクに摩擦力を付与可能な制輪子と、制輪子を支持するとともに、ピストンに取り付けられるガイドプレートと、ピストンと前記ガイドプレートを締結する締結部材と、を備える。ピストンはテーパ状の当接部を有し、締結部材は、ねじ軸を有するボルトと、ねじ軸に螺合するナットと、ナットとピストンとの間に位置し、ピストンの当接部に当接するテーパ状のナット側座面を有するワッシャと、ナットとワッシャとの間に設けられる皿ばねと、から構成される。【選択図】図3
