PROBLEM TO BE SOLVED: To solve the problem that installation work of a PTO shaft 366 to a transmission case 63 is complicated and a manufacturing cost is increased by increase of installation man-hours.SOLUTION: A vehicular drive apparatus according to the invention of the present application comprises the transmission case 63 for changing the speed of power of an engine 7. A shaft member 366 is rotatably supported via bearing bodies 367 and 368 in a cylindrical part 365 which is formed on the transmission case 63. On the inner peripheral side of the cylindrical part 365, step portions 373 and 374 are formed to protrude radially inward. At the end of the shaft member 366, a large diameter part 375 having a diameter larger than the inner diameter of the bearing bodies 367 and 368 is formed, or a rotation member 370 having a diameter larger than the inner diameter of the bearing bodies 367 and 368 is detachably installed. The bearing bodies 367 and 368 are caught by the large diameter part 375 or the rotation member 370 and the step portions 373 and 374 in the cylindrical part 365.SELECTED DRAWING: Figure 16
【課題】ミッションケース63に対するPTO軸366の組み付け作業が煩雑化し、組み付け工数の増加によって製造コストが嵩むという問題を解消する。【解決手段】本願発明の車両用駆動装置は、エンジン7の動力を変速するミッションケース63を備える。ミッションケース63に形成した筒状部365に、軸受体367,368を介して軸部材366を回転可能に軸支する。筒状部365の内周側には、半径内向きに突出した段差部373,374を形成する。軸部材366の端部には、軸受体367,368の内径よりも大径の大径部375を形成するか又は軸受体367,368の内径よりも大径の回転部材370を着脱可能に装着する。大径部375又は回転部材370と筒状部365内の段差部373,374とによって軸受体367,368を挟持する。【選択図】図16
