As described above, heat unit 28 has heat radiation structure.Heat radiation structure includes cooling fin 32.In the second face of main body 30 30B is equipped with multiple cooling fins 32.Multiple cooling fins 32 to 22 opposite side of friction member respectively with from extending with the second face 30B Mode is arranged.Cooling fin 32 can be integrally formed relative to main body 30, can also be separately formed.In the present embodiment, it radiates Piece 32 and main body 30 are integrally formed.When cooling fin 32 is separately formed, as long as example, being arranged in main body 30 for being inserted into cooling fin 32 Hole, cooling fin 32 is fixed on the hole by the methods of being pressed into or being bonded.In addition, in main body 30, for passing through system The through hole 30C of the pin of dynamic pincers is located between support portion 26 and heat unit 28.
Friction member 12 can be following structure.Friction member 12 has the rubbing surface 12A contacted with rotary body, packet Fiber containing zinc, first size L3 of the rubbing surface 12A on the first direction D1 parallel with rubbing surface 12A are 15mm or more and 30mm Hereinafter, second size L4 of the rubbing surface 12A on second direction D2 parallel with rubbing surface 12A and vertical with first direction D1 is 10mm or more and 20mm or less.
In the above-described embodiment, rubbing surface 12A can be divided into multiple.For example, rubbing surface 12A is divided into 2. Gap is formed between 2 rubbing surfaces for constituting rubbing surface 12A.In this case, friction area by 2 rubbing surfaces area Summation calculates.In addition, the first size L3 of friction member 12 and the second size L4 regard as continuously relative to by multiple rubbing surfaces Shape when face is set.
In the above-described embodiment, friction member 12 is without the friction material other than zinc fiber, but it may include zinc Friction material other than fiber.For example, friction member 12 other than comprising zinc fiber, can also include brass fiber.It is this In the case of, zinc fiber is more than brass fiber preferably in terms of volume ratio.
Manpower propulsion of bicycle of the unlimited Dingan County equipped with brake block 10 involved in embodiment, brake block 20.Manpower driving Vehicle includes road cycling, mountain bike, Mountain bike, city bicycles, shipping bicycle, bicycle of reclining, slide plate Vehicle.
