Abstract
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.
