Claim 6:
7. The electric drive apparatus as set forth in claim 1, wherein
the first housing has a tubular part to which the stator core is assembled,
in the tubular part of the first housing, there is formed an annular coolant passage through which coolant flows,
the coolant passage extends axially outside the stator core on both the first and second axial sides of the stator core, and
a dimensional relationship of D1<D2 is satisfied, where D1 is an axial distance between the stator core and a first axial end of the coolant passage on the second axial side of the stator core and D2 is an axial distance between the stator core and a second axial end of the coolant passage on the first axial side of the stator core.
