PURPOSE:To simplify constitution and improve the effect of the feeding apparatus in the actual use by bringing the wheels inclined at a prescribed inclination angle into press-contact onto the outer periphery of a shaft and installing a rotary driving apparatus onto the shaft. CONSTITUTION:Wheels 3 and 3' which are inclined at a prescribed set angle are press-attached onto the outer periphery of a shaft 1, and a rotary driving mechanism 2 is installed onto the shaft 1, and said wheels 3 and 3' are transferred by the contact revolution between the shaft 1 and the wheels 3 and 3'. Therefore, the constitution is made simple in comparison with the feeding mechanism consisting of a screw and a nut, and the feed quantity per revolution of the shaft 1 is varied by the tilt angle of the wheels 3 and 3' for the shaft 1, and the feed quantity can be varied from the rough feed to the fine feed by the control of the inclination angle, and the effect of the feeding apparatus can be improved in the actual use.
