Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a piston pump which is provided with an inexpensively manufacturable piston, and also excellent in respect of the on-off characteristic of a valve. SOLUTION: This piston pump 10 is a piston pump for a car braking device, and it is provided with a pump casing in which a bush is inserted, therefore a piston to be driven for reciprocating stroke motion is accepted in the bush as being slidable in the axial direction, and the piston is provided with a first valve, controlling the break through direction of a fluid which is forcibly fed by the piston pump 10 and flows through this pump. The first valve is attached to the bush. In this case, the piston pump 10 is provided with a second valve 38 controlling the break through direction of the fluid being forcibly fed by the pump 10 and flowing through the pump 10, and this second valve 38 is set up in the bush 16.
