The outer circumferential surface G of the rotor R is polished by T, and for this reason, both ends of the shaft S of the rotor R are attached to the pair of opposing V-shaped shaft receiving parts A1 and A1 of the rotor support mechanism part A. Since the outer circumferential surface G of the rotor R is polished by supporting each part rotatably, the outer circumferential surface G of the rotor R has a high degree of concentricity with the outer circumferential surface G of the rotor R and the outer circumferential surface of the shaft S.

E2 , the structure of the inclination angle adjustment mechanism E can be simplified, and the orthogonal direction Nd perpendicular to the running direction Bd of the drive belt B1 and the rotational axis R0 of the rotor R. It is possible to adjust the angle formed by Reliable contact can be made, and the outer circumferential surface G of the rotor R can be polished well.
