<p>PROBLEM TO BE SOLVED: To suppress oil discharged from a first clutch and a second clutch at a low cost. SOLUTION: Oil supply means is arranged which supplies oil, accompanied by the gear shift operation of a shift lever 7, to a first clutch C1 or a second clutch C2 corresponding to a side provided for transmission out of a first transmission mechanism and a second transmission mechanism which are connected in parallel to each other, a first oil exhaust passage d1 from the first clutch C1 and a second oil exhaust passage d2 from the second clutch C2 are arranged, a first oil exhaust valve v1 and a second oil exhaust valve v2 are arranged in the first oil exhaust passage d1 and the second oil exhaust passage d2 respectively, a first restrictor s1 which increases supply pressure accompanied by oil supply to the first clutch C1 and a second restrictor s2 which increases supply pressure accompanied by oil supply to the second clutch C2 are arranged, and a first pilot pressure impressing passage p1 for impressing supply pressure to the first clutch C1 to the second oil exhaust valve v2 as pilot pressure and a second pilot impressing passage p2 for impressing supply pressure to the second clutch C2 to the first oil exhaust valve v1 as pilot pressure are arranged.</p> |
