のピストン対向型キヤリパ。 A plurality of three or more cylinder holes are arranged in parallel in the circumferential direction of the disk in both working parts of the caliper, which is disposed across a pair of friction pads arranged oppositely on both sides of the disk rotor. To,
In a vehicle disc brake in which a piston for pressing the friction pad against a disc rotor is inserted, an intermediate cylinder hole among the plurality of cylinder holes is formed to have a smaller diameter than cylinder holes on the disk insertion and rotation sides. In addition, a piston-opposed caliper for a vehicle disc brake is characterized in that a boss portion on the outer periphery surrounding an intermediate cylinder hole is reinforced with build-up or ribs.
