Claims

[Scope of utility model registration request]

A first brake pad is displaced by a hydraulic piston slidably housed in a hydraulic cylinder formed at one end of the caliper, and a first brake pad is displaced by an arm formed at the other end of the caliper due to the reaction force. A disc brake that performs braking by clamping a disc rotor fixed to a wheel side with a second brake pad, characterized in that a detour thick part is formed in the axial direction of the hydraulic piston and in the middle of the wall thickness section. disc brake.
