PURPOSE:To eliminate oil pressure pipings exposed to the outside, by building an oil pressure generating machine in a shaft that oscillation supports a caliper. CONSTITUTION:A support shaft 9 piercing a hole portion 10a of a fixing portion 10 penetrates a hole portion 4a of a caliper 4, and supports the caliper 4 in an oscillation-possible shape. When right pulling a rope 21 interlocking with a braking functioning lever, a piston 14 smoothly fitted into a cylinder 13 right moves, and oil pressure is generated in an oil chamber 22. Oil pressure reaches the inside of an oil pressure functioning cylinder in the caliper 4 through a flow path in the caliper 4, thus working a disc brake. Since an oil pressure generating machine is built in the support shaft 9 as a fixing body, the trouble of the failure of oil pressure pipings can be eliminated. |
