摘要： An input member and a differential gear mechanism include a part arranged on an axial first side with respect to a rotary electric machine. The differential gear mechanism is connected to a first wheel via a shaft member (61) including a part that is arranged on an axial second side with respect to the differential gear mechanism. A case (2) includes an outer peripheral support portion (25) that is formed along a core outer peripheral surface (12a) that is an outer peripheral surface of a stator core (12), and that supports the core outer peripheral surface (12a) in a radial direction (R). A notch portion (26A) in which the outer peripheral support portion (25) is notched over an entire area of an arrangement area of the stator core (12) in an axial direction is formed in the outer peripheral support portion (25), and the notch portion (26A) is arranged at a position that is between the core outer peripheral surface (12a) and the shaft member (61) in the radial direction (R), and that overlaps the shaft member (61) as seen in the radial direction along the radial direction (R).

摘要： A rotating electrical machine (1) and an input member (3) are placed on a first axis (A1), a counter gear mechanism (4) is placed on a second axis (A2), and a differential gear mechanism (5) is placed on a third axis (A3). The input member (3), the counter gear mechanism (4), and the differential gear mechanism (5) have portions placed on an axial first side with respect to the rotating electrical machine (1). A pump portion (7A) is placed on the opposite side of an imaginary plane (B) passing through the first axis (A1) and the third axis (A3) from the second axis (A2), and is placed at a location that overlaps at least one of the rotating electrical machine (1) and the differential gear mechanism (5) in an axial view. The pump portion (7A) is placed on the axial first side with respect to the rotating electrical machine (1).

摘要： A vehicle drive device (100) includes: a rotary electric machine 1; a drive transmission mechanism (10) provided in a power transmission path (P) connecting a rotor shaft (122) of the rotary electric machine (1) and a wheel (W); a first hydraulic pump (71) driven by a driving force transmitted through the power transmission path (P); a second hydraulic pump (72) driven by a driving force source (72a) independent of the power transmission path (P); a first oil passage (91) that supplies oil discharged from the first hydraulic pump (71) to a rotor bearing (B1) that supports the rotor shaft (122) such that the rotor shaft (122) is rotatable; and a second oil passage (92) that supplies oil discharged from the second hydraulic pump (72) to an inner peripheral surface (122d) of the rotor shaft (122).
