PURPOSE: A heat generated in a braking is discharged instantly to provide a good braking performance. CONSTITUTION: A brake disk(2) rotates by a driving power of an engine. A caliper(6) is installed in outer circumference of the brake disk(2). A pressing member is installed inside of the caliper, and pushes the side of the brake disk(2) by a brake hydraulic pressure. A heat discharging member is buried in the caliper(6), and absorbs the heat in the caliper(6) and discharges the heat. The heat discharging member has a passage to circulate a heat-absorbing material. The heat discharging member comprises a heat-absorbing plate, and a plurality of heat-discharging pins(20) extending from the heat-absorbing plate to the outside of the caliper(6).
