<p>PURPOSE: To exactly carry out an adjusting reaction by superimposingly impressing an alternative load for reducing frictional force to a force or a moment acted by an adjusting member for operating a frictional element to extinguish a hysteresis action. CONSTITUTION: In the case where a friction device 121 is operated, a motor 133 is driven, a pinion 135 is rotated through an inertia travel 137 and an adjusting ring 128 is rotated through a supporting ring 163. A forcing circular plate 140 is forced to a tappet 141 by an action of a wedge tooth 130 and is engaged therewith. In this case, a forcing bearing 139 is buried between a radial surface of the adjusting ring 128 and the forcing circular plate 140 and since the forcing circular plate 140 is rotated with a differential carrier 112, a friction is reduced and an engaging force of the friction device 121 can be adjusted without a hysteresis.</p> |
