    摘要： A rotary electric machine (1), a transmission (2), and a differential gear device (3) are disposed coaxially. The transmission (2) includes a first helical gear (HG1) and a second helical gear (HG2) that meshes with the first helical gear (HG1). A case (10) includes a first case member (6) including a stator support portion (61) that supports a stator (11) of the rotary electric machine (1), a second case member (7) that is structured as a separate member from the first case member (6) and forms a gear chamber (C2) that houses the transmission (2) and the differential gear device (3), and a support member (8) that supports the first helical gear (HG1) in an axial direction (L). The support member (8) rotatably supports a rotor (12) of the rotary electric machine (1) via a rotor bearing (B1), and is fixed to the second case member (7).

    摘要： An inverter (10) that controls a rotary electric machine (1) is above the rotary electric machine (1) and overlaps the rotary electric machine (1) when viewed in a vertical direction (V). A differential gear assembly (4) includes a differential input gear (41) being an input element in the differential gear assembly (4). The differential input gear (41) is at least partially located in an oil reservoir (9a) in a case (9) and is located on a second axis (X2) different from a first axis (X1) being a rotation axis of a rotor (12) in the rotary electric machine (1). The first axis (X1) is below the second axis (X2). The rotor (12) has a lower end located above a lower end of the differential input gear (41).

    摘要： Provided is a magnetic power transmission device capable of improving the power transmission efficiency and transmission capability while maintaining the merits obtained when performing power transmission by using a magnetic force and reducing the manufacturing cost. The magnetic power transmission device (1) includes: an external rotor (11) having a plurality of left and right permanent magnets (11c) arranged in the circumferential direction; an internal rotor (12) having a plurality of permanent magnets (12c) arranged in the circumferential direction; and an intermediate rotor (13) having a plurality of left and right soft magnetic bodies (13d, 13e) arranged in the circumferential direction. When the left and the right permanent magnets (11c) are positioned to oppose to the permanent magnets (12c): if the left permanent magnet (11c) has a polarity different from that of the left side of the permanent magnet (12c), the right permanent magnet (11c) has a polarity identical to that of the right side of the permanent magnet (12c); and if one of the soft magnetic bodies (13d, 13e) is positioned between the permanent magnets (11c, 12c), the other is positioned between the two adjacent permanent magnets (11c, 12c).
