Claims

[Scope of utility model registration request]

The hydraulic disc brake caliper is equipped with a wire-driven parking brake device, and a rod connected to the piston of the hydraulic disc brake caliper is provided to protrude from the caliper body in a liquid-tight manner, and a parking brake housing is attached to the caliper body so as to surround this rod. A cylindrical nut is fixed and rotated by the tensile force of a wire inside the housing, and a cam mechanism is provided between the cylindrical nut and the housing to slide the cylindrical nut in the axial direction by rotation of the cylindrical nut. In a parking brake device having an adjustment bolt for adjusting the parking brake that is screwed onto the inner peripheral surface of the cylinder nut, an arm that is connected to the wire and rotates the cylinder nut is fixed to the outer peripheral surface of the cylinder nut with a lock nut, A grip part is formed on the outer end of the adjustment bolt, and a stopper mechanism is provided that allows adjustment of the adjustment bolt and prevents it from rotating relative to the cylinder nut, and the grip part is gripped to turn the adjustment bolt, and the parking brake is applied. A parking brake device characterized in that the device is adjustable.
