The invention provides a vehicle drive device, which comprises: a first bearing (B1) that is placed between a rotor support member (60) and a case (4) in a radial direction (R), and that restricts the movement of the rotor support member (60) to an axial direction first side (L1) with respect to the case (4); and a second bearing (B2) that is placed between a connecting shaft (30) and the case (4) in an axial direction (L), and that restricts the movement of the connecting shaft (30) to an axial direction second side (L2) with respect to the case (4). A fluid transmission device is placed at the axial direction first side (L1) with respect to the connecting shaft (30). The rotor support member (60) comprises a cylindrical part (71) that is formed in a cylinder shape extending in the axial direction (L) and that is fitted on the outer peripheral surface of the connecting shaft (30). In the connecting shaft (30), movement to the axial direction first side (L1) with respect to the cylindrical part (71) is restricted.

    本发明提供一种车用驱动装置。车用驱动装置具备:配置于转子支承部件(60)与壳体(4)的径向(R)之间,限制转子支承部件(60)相对于壳体(4)向轴向第一侧(L1)的移动的第一轴承(B1);以及配置于连结轴(30)与壳体(4)的轴向(L)之间,限制连结轴(30)相对于壳体(4)向轴向第二侧(L2)的移动的第二轴承(B2)。流体传动装置相对于连结轴(30)配置于轴向第一侧(L1)。转子支承部件(60)具备形成为沿轴向(L)延伸的筒状并与连结轴(30)的外周面嵌合的筒状部(71)。连结轴(30)相对于筒状部(71)向轴向第一侧(L1)的移动被限制。
