To prevent the deterioration of the sliding property of a rotor due to machining errors and reduce the cost and weight.
A ring-like spacer made of iron or Teflon and having the outer diameter smaller than that of a rotor 2 is fitted between the rotor side end face of a rear head 6 and the rear side end face of a cam ring 1. Fixed gaps are maintained between the end face of the cam ring 1 and the rotor side end face of the rear head 6 and between the end face of the cam ring 1 and the rotor side end face of a front side block 3, the machining errors on the end face of the rotor 2 and the rotor side end face of the rear head 6 and the assembling errors of the rotor 2 and the rear head 6 are absorbed, and the abrasion on the end face of the rotor 2 can be suppressed. The gap between the end face of the rotor 2 and the rotor side end face of the rear head 6 and the gap between the end face of the rotor 2 and the rotor side end face of the front side block 3 become narrower respectively than those when no spacer 70 is used, and performance is improved.
