<p>PROBLEM TO BE SOLVED: To minimize the deformation of a caliper by sharing torque acting on each friction pad between the inlet side and the outlet side in the rotational direction of a disc with a fitting member. SOLUTION: Recessed pad supporting parts 17, 18 positioning on the inlet side and the outlet side in the rotational direction of the disc 11 and perpendicular crossing to a tangent line of the disc 11 are installed on the inner side of the fitting member 12. Projecting fitting projection parts 23A, 23B fitting to the pad supporting parts 17, 18 are installed in a friction pad 21 on the inner side. The fitting projection part 23A is formed wider in the tangent line direction of the disc 11 than the fitting projection part 23B. Thereby, in braking of the disc 11, the fitting projection part 23A on the inlet side in the rotational direction of the disc 11 is brought into contact with the pad supporting part 17 earlier than the fitting projection part 23B on the outlet side in the fitting member 12. The fitting projection on the outlet side in the rotational direction of the disc 11 is brought into contact with the pad supporting part earlier than the fitting projection part in the inlet in the friction pad on the outer side.</p> |
