PROBLEM TO BE SOLVED: To provide a shaft drive type vehicle which makes a transmission structure between a drive shaft and a gear engaged with a bevel gear on the most downstream side, advantageous in reducing weight, and can finely lubricate a part of spline coupling.SOLUTION: A shaft drive type vehicle is equipped with a final gear box 31 which rotatably stores a pinion gear 33 and a bevel gear 35, and stores oil. At a downstream end of a drive shaft 29, a recessed portion 29H in which an upstream end of a pinion gear shaft portion 33A is put is provided. The recessed portion 29H and the upstream end of the pinion gear shaft portion 33A are spline-coupled so as to integrally rotate the drive shaft 29 and a pinion gear 33 and so as to relatively move in an axial direction. Between the pinion gear 33 and the recessed portion 29H, a space portion S1 permitting movement in the axial direction between the drive shaft 29 and the pinion gear 33 is provided. The pinion gear 33 is provided with a hollow portion 33 penetrating the pinion gear 33 in an axial direction, and leading the oil to the space portion S1.SELECTED DRAWING: Figure 3

    【課題】ドライブシャフトと最下流のベベルギアと噛合するギアとの間の伝達構造を軽量化に有利な構成にしつつ、スプライン結合の箇所を良好に潤滑可能なシャフトドライブ式車両を提供する。【解決手段】ピニオンギア33及びベベルギア35を回転自在に収容するとともにオイルを収容するファイナルギアボックス31を備え、ドライブシャフト29の下流端に、ピニオンギア軸部33Aの上流端が入る凹部29Hを備え、凹部29Hとピニオンギア軸部33Aの上流端とは、ドライブシャフト29及びピニオンギア33を一体に回転自在、且つ軸方向に相対移動自在にスプライン結合され、ピニオンギア33と凹部29Hとの間に、ドライブシャフト29とピニオンギア33との間の軸方向の移動を許容する空間部S1を備える。また、ピニオンギア33に、当該ピニオンギア33を軸方向に貫通してオイルを空間部S1に導く中空部33Xを設ける。【選択図】図3
