Claims

[Scope of utility model registration request]

A rotating shaft, a rotor rotated through the rotating shaft, a large number of vanes attached to the rotor so as to be freely protrusive and retractable in a substantially radial direction, a cam ring housing the rotor with the vanes attached, and a cam ring sandwiching the cam ring. The inner circumference of the cam ring has a front body and a rear body that form a pump chamber, and when the rotor rotates, the vanes attached to the rotor slide while being pressed against the inner circumference of the cam ring. The oil, etc. in the oil tank is introduced into the pump chamber via the suction passage by the volume change between each vane at that time, and the oil, etc. introduced by the mini is used as nutrients in the discharge passage and discharged to the outside. In a vane pump configured as shown in FIG.
The input side rotation shaft is rotatably supported by the rotor, and the rotor side rotation shaft is integrally formed with the rotor, and the input side rotation shaft and the rotor side rotation shaft are universally coupled. A vane pump characterized by:
