Abstract
The thrust load of the friction transfer mechanism is adjusted with an electric actuator, the thrust load of said friction transfer mechanism is be increased with a fixed inclination, at the first stage from the time control is started to the time the predetermined time elapses, the inclination of the thrust load of said friction transfer mechanism is set to the inclination smaller than that of the thrust load of said friction transfer mechanism at said first stage, at the second stage where said friction transfer mechanism moves further to the predetermined position, and the thrust load of said friction transfer mechanism may be increased with the inclination larger than that of the thrust load of said friction transfer mechanism at said second stage, at the third stage where the predetermined time elapses further.
