The planetary rollers are rotated about the axis of the rotor shaft and about their own axes, thereby converting rotary motion of the rotor shaft to linear motion of the planetary rollers A helical groove is formed in the radially outer surface of each planetary roller in which a helical rib formed on the radially inner surface of the outer ring member is received. The helical groove has a pitch equal to that of the helical rib and a lead angle different from that of the helical rib. The amount of the linear motion of the planetary rollers relative to the amount of the rotary motion of the rotor shaft is determined by the difference in lead angle between the helical groove and the helical rib. | ||||||
