To reduce cost for manufacturing a vehicular drive device by reducing the number of types of gear while miniaturizing a vehicular transmission.SOLUTION: A vehicular drive device includes: a main input shaft 11 having an input gear 11C for third/fifth speed stages and input with power from an engine 20; and an idle shaft 12 having an idle gear 12A for a third speed stage engaging the input gear 11C for the third/fifth speed stages; and a counter shaft 14 having a counter gear 14C for a fifth speed stage engaging the input gear 11C for third/fifth speed stages. The idle gear 12A for the third speed stage and the counter gear 14C for the fifth speed stage are formed so as to have an identical shape.SELECTED DRAWING: Figure 6
【課題】車両用変速機の小型化を図りつつ、ギヤの種類を削減して車両用駆動装置の製造コストを低減すること。【解決手段】3速/5速段用の入力ギヤ11Cを有し、エンジン20の動力が入力される主入力軸11と、3速/5速段用の入力ギヤ11Cに噛み合う3速段用のアイドルギヤ12Aを有するアイドル軸12と、3速/5速段用の入力ギヤ11Cに噛み合う5速段用のカウンタギヤ14Cを有するカウンタ軸14とを備えており、3速段用のアイドルギヤ12Aと5速段用のカウンタギヤ14Cが同一形状に形成されている。【選択図】図6
