A structure of a brake caliper is provided to ensure stable braking operation and to improve endurance of a braking device by effectively radiating heat transferred from a piston. A structure of a brake caliper comprises a cooling boss(5), a guide member(7) and a sealing unit(9). The cooling boss having a hollow pipe shape protrudes from a pressure receiving surface of a piston(1) and extends by passing through a caliper body(3). The guide member is formed through the caliper body to guide reciprocation of the cooling boss. The sealing unit is disposed between the guide member and the cooling boss, and includes a mounting groove(11) formed at an inner peripheral portion of the guide member and an oil ring(13) installed in the mounting groove.
