Abstract:
A vehicular drive system with a simple configuration capable of lubricating a bearing and reducing a drag loss of a sensor rotor caused by a lubricant after lubricating the bearing is realized. The vehicular drive system includes a rotating electric machine (MG) serving as a driving force source accommodated in a case (1). The case (1) has a supporting wall (3) on a side of A1 in a first axial direction, and includes: a rotor supporting member (30) rotatably supporting a rotor (Ro); a bearing (61) arranged between the supporting wall (3) and the rotor supporting member (30); a lubricant supplying part (LS) supplying a lubricant to the bearing (61) from radially inside; and a rotation sensor (11) arranged radially outside of the bearing (61). The case (1) has a communication passage (LA) provided in at least one of the rotor supporting member (30) and a sensor rotor (12) and communicating a first space (V1) formed between the supporting wall (3) and the rotor supporting member (30) and a second space (V2) formed between the sensor rotor (12) and the rotor supporting member (30).
