<p>PURPOSE: To make common parts in relation to hydraulic actuators for a clutch, having different capacities. CONSTITUTION: An accumulator 4 for accumulating pressure oil to be supplied from a pump to a clutch provided on an automatic transmission is provided with a valve body 16 provided with a columnar space 15, a piston 19, a pressure oil supplying port 21, a coil spring 20, and a blocking member 22. The piston 19 can be moved within the specified moving range in the columnar space 15 and provided with a throttle 23 penetrating in the moving direction. The pressure oil supplying port 21 is provided on one end of the columnar space 15 so as to be connected to the pump. The coil spring 20 energizes the piston 19 to the side plate member 17 side of the columnar space 15. The blocking member 22 blocks the throttle 23 when the piston 19 is arranged on the moving end on the side plate member 18 side of the columnar space 15.</p> |
