PURPOSE:To shorten the wheel base of a vehicle, by arranging a first clutch, a second clutch and a third clutch on the axially opposite side of a drive gear. CONSTITUTION:A first clutch 14, a second clutch 17 and a third clutch 19 are arranged on the axially opposite side of a second gear 16. Therefore, they do not interfere with each other in the direction of wheel base of a vehicle irrespective of the dimensions of the drive gear or the second gear. Accordingly, the diameterical dimension of the drive gear 12 or the second gear 16 may be set to be less than that of any one of the first, second and third clutches 14, 17, 19 so that the wheel base may be made to be short.
