Abstract

A motor unit (2) includes: a housing (10); a stator core (46); a stator coil (48) provided on the stator core (46) and having a first coil end (48A) protruding from an end surface of the stator core (46); a bus bar module (14) that is connected to the first coil end (48A) of the stator coil (48); and a spacer (16) provided between the end surface of the stator core (46) and the bus bar module (14) in the axial direction. The housing (10) includes a first supply flow path (26B) that has a housing opening (27B) on a surface facing the spacer (16) in the radial direction and supplies a refrigerant toward the spacer (16). The spacer (16) includes a second supply flow path (80) that extends between a first spacer opening in the inner peripheral surface of the spacer (16) and a second spacer opening in the outer peripheral surface of the spacer (16) and supplies the refrigerant toward the first coil end (48A).
