PURPOSE:To prevent burning of a first and a second synchronous contact faces of a double cone synchro by adding a few parts in a transmission having an oil pump. CONSTITUTION:A first synchronous contact face is constituted of a tapered face formed on the inner circumference of synchronizer rings 27 and 28 rotated integrally with a synchro hub 19 when a synchro sleeve 21 is moved, and of a cone face formed on the outer circumference of outer cones 31 and 32 engaged with clutch gears 36 and 37 rotated integrally with an input gear 18 which is rotatably inserted to a main shaft. A second synchronous contact face is constituted of a tapered face formed on the inner circumference of the outer cone and a cone face formed on the outer circumference of inner cones 33 and 34. A nozzle 42 is mounted on a case 12 of a transmission 11 toward a synchronous engaging apparatus, and an oil pump driven by a transmission gear 17 discharges oil reserved in the case, and the nozzle jets this oil to a clearance between the synchronizer ring and the clutch gear. |
