Claims

[Scope of Claim for Utility Model Registration] A cylinder part and a reaction part that respectively press the friction pads against the disk, and a slide part that is fixed to the cylinder part and slidably fits into a guide pin fixed to the torque member and a pin hole. In a pin sliding caliper, a portion of the inner circumferential surface of the pin hole near the open end on the side closer to the disk, a portion on the outer circumferential side of the disk from the pin hole center line, and a portion near the open end on the opposite side. A pin slide type caliper for a disc brake, characterized in that a relief part is provided in a part on the inner peripheral side of the disc from the pin hole center line, the distance from the pin hole center line being larger than in other parts.
