PROBLEM TO BE SOLVED: To miniaturize a fluid pressure pump in which a piston is operated by driving force of an electric motor.SOLUTION: A cam mechanism C and a pump portion P are disposed coaxially with a rotary axis X of an output shaft 2 of an electric motor M, a rotating member 21 rotated integrally with the output shaft 2, and a cam member 23 having a cam face 23S with which the rotary member 21 is brought into contact, are disposed as the cam mechanism C, and a piston 31 reciprocated integrally with the cam member 23, and a spring 32 operating the piston 31 in a returning direction, are disposed as the pump portion P. The cam mechanism C operates the piston 31 in a going direction by pressing force acting on the cam face 23S from the rotary member 21 in rotation of the output shaft 2, and the spring operates the piston 31 in the returning direction by biasing force. |
