A reciprocating pump gas venting mechanism (2) in which the reciprocating member is provided with a cam surface that contacts the suction valve at the bottom dead center of the stroke and shifts the suction valve laterally to create an opening. In a reciprocating pump having a reciprocating member that is driven, the cylinder space or a liquid passage connected to the cylinder space is connected to the outside of the pump by a gas vent passage, an on-off valve that opens and closes the gas vent passage, and a valve that operates in conjunction with the motor. A reciprocating pump gas venting mechanism, comprising a motion conversion mechanism that operates the on-off valve.
