BRAKE PAD AND CALIPER DEVICE

摘要

A brake pad 10 is adapted to be used in an opposing type caliper device and can brake a rotation of a disc 200. The brake pad 10 includes a friction material 12 provided on the side of the disc 200 and a back plate 11 bonded to the friction material 12 on the opposite side of the disc 200. The back plate 11 is formed of a back-plate composition including a resin and a plurality of fibers. The back plate 11 has an engagement portion 111 into which an attachment portion 70 of the caliper device 100 is capable of being inserted, and with which the inserted attachment portion 70 is engaged. A thickness of a region of the back plate 11 where the engagement portion 111 is provided is larger than a thickness of a region of the back plate 11 where the engagement portion 111 is not provided.
