<p>PURPOSE:To prevent faulty clutch engagement by providing an oil well on the opposite side relative to the annular piston on the inner circumference of the outer cylinder of the annular cylinder for fluid actuator for clutch so that the centrifugal oil pressure due to the residual oil in the oil passage can be cancelled. CONSTITUTION:An annular piston 234 in the second multi-plate clutch mechanism 230 is actuated by an oil servo, an oil passage 235 connected to the oil servo, and an oil pressure control device that supplies and drains the operating oil to the oil passage 235. A spring 236 that forces the annular piston 234 to the side opposite to the multi-plate clutch 230, and spring attaching hardware 238 are disposed inside the rear outer cylindrical part 163, and an oil well 237 is formed by the annular piston 234, inner circumference of the rear outer cylindrical part 163 and spring attaching hardware 238. The annular piston 234 consists of a piston shaft actuating section 234A that receives the centrifugal oil pressure of the operating oil stored in the oil well 237 and a pressure piston section 234B.</p> |
