BRAKE PAD AND CALIPER DEVICE

摘要

A brake pad 10 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. A thickness of a peripheral region of the back plate 11 on the side of a center of the disc 200 is larger than a thickness of a peripheral region of the back plate 11 on the side of an outer circumference of the disc 200. In the case where a minimum value of the thickness of the peripheral region of the back plate 11 on the side of the center of the disc 200 is defined as "h 2 [mm]" and a maximum value of the thickness of the peripheral region of the back plate 11 on the side of the outer circumference of the disc 200 is defined as "h 1 [mm]", h 1 and h 2 satisfy a relationship of "h 2 -h 1 <3".
