Abstract
A motor unit disclosed herein may comprise: a rotor supported rotatably; a stator core facing the rotor in a radial direction; a stator coil disposed on the stator core; and a first busbar having a plate shape and including a base end connected to the stator coil and a distal end including a connection terminal. The first busbar may include a linear section extending along a straight line. The linear section of the first busbar may include a reinforced section where a thickness direction of the first busbar varies along a width direction of the first busbar.

- a rotor supported rotatably;
- a stator core facing the rotor in a radial direction;
- a stator coil disposed on the stator core;
- and
- a first busbar having a plate shape and including a base end connected to the stator coil, a distal end including a connection terminal, and a linear section extending along a straight line parallel to a rotation axis of the rotor and between the base end and the distal end, wherein
- the linear section of the first busbar includes a reinforced section, a first flat section, and a second flat section, wherein the reinforced section is between the first flat section and the second flat section,
- a cross-sectional shape orthogonal to the straight line of the reinforced section comprises a first portion having a first direction as a thickness direction and a second portion having a second direction as a thickness direction, wherein the first direction is different from the second direction, and
- a cross-sectional shape orthogonal to the straight line of each of the first flat section and the second flat section has a different shape than the cross-sectional shape of the reinforced section.
