To provide a vehicle drive unit which ensures parallelism of a plurality of shafts constituting a transmission mechanism and prevents misalignment in the shaft direction to be capable of assembling the shafts into a transmission case at the same time to improve workability of assembling the transmission mechanism.SOLUTION: A transmission mechanism 60 of a drive unit 4 comprises: a main input shaft 11; and a counter shaft 14 which is connected through input gears 11A, 11B, 11C, 11D and counter gears 14A, 14B, 14C, 14D with the main input shaft 11. The counter gear 14 includes a reduction driven gear 14E engaged with a reduction drive gear 13B of an idle shaft 12 in which a part of the outer periphery of the reduction driven gear 14E is entered between the input gear 11B for the second speed stage and the input gear 11C for the third speed stage/fifth speed stage in the axial direction of the main input shaft 11.SELECTED DRAWING: Figure 6
【課題】変速機構を構成する複数の軸の平行を確保しつつ、軸方向にずれることを防止して、複数の軸を変速機ケースに同時に組み付けることができ、変速機構の組付作業の作業性を向上できる車両用駆動装置を提供すること。【解決手段】駆動装置4の変速機構60は、主入力軸11と、主入力軸11に入力ギヤ11A、11B、11C、11Dとカウンタギヤ14A、14B、14C、14Dを介して連結される主入力軸11とを有し、カウンタ軸14は、アイドル軸12のリダクションドライブギヤ13Bに噛み合うリダクションドリブンギヤ14Eを有し、リダクションドリブンギヤ14Eの外周部の一部は、主入力軸11の軸方向で2速段用の入力ギヤ11Bと3速/5速段用の入力ギヤ11Cの間に入り込んでいる。【選択図】図6
