Claims

[Scope of utility model registration request]

A boot is interposed between the opening of the cylinder formed in the caliper that straddles the outer circumference of the rotor and the outer circumference of the piston that is slidably assembled in the cylinder in the axial direction. In a disc brake in which a shim is interposed between a back metal of a pad facing the shim, and the shim is directly attached to the piston in a sliding direction so as to be removable, the shim is attached to the outer periphery of the shim. A shielding portion is formed to cover a portion of the boot facing the rotor, and a bent portion of the shielding portion on the axis side of the rotor is bent toward the boot and surrounds an outer periphery of the boot, and □ A disc brake characterized in that the shim is formed with a detent pawl that removably engages with the back metal of the pad in the radial direction of the rotor.
