求項(1)に記載のマスタシリンダ。[Claims for Utility Model Registration] (1) A piston cup that is fluid-tightly and slidably inserted into the inner hole of a cylinder body that accommodates hydraulic fluid through a piston cup. A piston that forms a pressure chamber that constantly communicates with the hydraulic pipe line and a replenishment chamber that constantly communicates with the reservoir through an outlet port formed on the inner peripheral surface of the hole; a return spring that urges toward the operating position; a holder fixedly provided at the bottom of the inner hole within the pressure chamber;
A piston side member is provided in the inner hole between one bottom end of the inner hole, which covers the outlet port with its outer peripheral surface and is locked to the holder, and the inner peripheral surface of the inner hole. a cylindrical collar member fitted with a gap larger than the gap between the end portion and the inner circumferential surface of the inner hole; The master cylinder is provided with a communication means that allows communication between the pressure chamber and one end of the collar member. (2) The other end of a rod, one end of which is attached to the piston, is removably engaged with the holder, and the return spring is interposed between the piston and the holder, and the return spring is interposed between the piston and the holder. The master cylinder according to claim 1, characterized in that a non-operating position is defined.
