A hydraulic circuit includes a first shift valve and a second shift valve that are provided in series between a source oil path through which oil whose pressure has been regulated flows and a first clutch oil path and a second clutch oil path. The first shift valve is selectively switchable between a first switching state where a first communicating oil path and the first clutch oil path are communicated and a second switching state where a second communicating oil path and the second clutch oil path are communicated, and the second shift valve is selectively switchable between a third switching state where the source oil path and the first communicating oil path are communicated and a fourth switching state where the source oil path and the second communicating oil path are communicated.

Hydraulic circuit of driving device for vehicle

A shift actuator includes a first and a second fluid pressure chamber providing fluid pressure to each of a first and a second piston, a hydraulic control device for regulating pressure of hydraulic oil discharged from a hydraulic source and supplying the same, a first and a second oil passage communicated from the hydraulic control device to each of the first and the second fluid pressure chamber, a first and a second connecting portion for connecting the first oil passage with the first fluid pressure chamber and the second oil passage with the second fluid pressure chamber, and a first and a second orifice portion having a diameter smaller than the inner diameter of the first and the second oil passage provided to each of the first and the second connecting portion.
