<p><P>PROBLEM TO BE SOLVED: To provide an operation control device for changing a torque transmission characteristic. <P>SOLUTION: The operation control device comprises: a clutch part 21 changing a torque transmission state between a rotational shaft 11 and a drive pinion shaft 17 depending on oil pressure; and a pump part 23 pressure-feeding oil according to rotation input to the rotational shaft 11. The pump part 23 has a circumferential recesses and projection part of a pump cam formed to a carrier housing 7, and a plunger supported by the carrier housing 7, and brought into elastic-contact with the recess and projection part so that the plunger is reciprocated by rotation relative to the recess and projection part to pressure feed the oil. Depth and height in the recess and projection part of the pump cam is gradually changed in a direction along a rotation center, the recess and projection part and plunger are supported to be relatively movable along the rotation center, and a control means is provided for changing a relative position of the recess and projection part and the plunger. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
