PURPOSE:To aim at a reduction in the number of parts items and miniatruization, by installing a parking gear unrotatively, while constituting an output shaft so as to be locked through engagement between a final drive gear and the parking gear by making them into axially relative movement. CONSTITUTION:Placing a backward driven gear 65 on the left end position, a spline tooth 65 of a forward driven gear 62 is made to come into a state of being disengaged with a backward intermediate gear 67 of an intermediate gear 54 so that its neutral position is maintained. From this state, when the backward driven gear 65 is shifted to the right end position, this gear 65 engages a gear 70 for parking use installed in aparking shaft 55. Since this parking gear 70 is solidly unified with the parking shaft 55 in its rotating direction, and output shaft 53 comes into a state of being locked to a transmission case 51 whereby parking is securable. Thus, with speed change gear parts used in common, a reduction in the number of parts items and the miniatruization of a speed change gear are well promoted. |
