PURPOSE: To reduce the dimension of the captioned device by reducing the operation load of a solenoid by constituting the captioned device so that a cavity is generated between a lifter pin in the contact of a cam body with the control shaft in the constitution in which flow rate is adjusted by shifting the lifter pin by the action of the solenoid.
CONSTITUTION: A lubricating oil pump 1 is equipped with a piston 3 fitted into a housing 2, and a plunger 5 is fitted into the piston 3. The piston 3 is revolution-driven by meshing a driving worm 11 turned by the engine revolution with a worm wheel 10 formed in the lower part of the piston 3, and slidingly moved by attaching a lifter pin 26 driven by a solenoid 31 according to the number of engine revolution onto a cam body 12 fixedly installed at the lower edge part. In this case, a control shaft 32 having a small diameter part 35 and a cut circular cam stopper 36 is arranged in the direction crossing at right angles with the lifter pin 26, and a cavity is generated between the lifter pin 26 in the division in the contact between the cam body 12 and the small diameter part 35.
