Vehicle electric motor

A vehicle electric motor comprising:

• a tubular-shaped stator core constituted by electromagnetic steel sheets that are laminated on each other;
• a rotor disposed inside said stator core so as to be rotated about an axis;
• and
• a housing storing therein said tubular-shaped stator core and said rotor, and including a circumferential wall and axially opposite end walls that are opposed to each other in a direction parallel with said axis,
• wherein said stator core is fixed at one of axially end portions thereof to one of said axially opposite end walls of said housing,
• wherein said housing includes a stator-core-inclination restraining portion that protrudes from an inner circumferential surface of said circumferential wall of said housing toward a part of an outer circumferential surface of said stator core, said part being located on a side of the other of said axially end portions of said stator core,
• wherein said housing is constituted by a casing and a casing cover that are fixed to each other,
• wherein said casing includes an outer circumferential wall that is a part of said circumferential wall of said housing, a bottom wall that is said one of said axially opposite end walls of said housing and a mating surface that is provided by a distal end surface of said outer circumferential wall of said casing or provided in vicinity of said outer circumferential wall of said casing,
• wherein said casing cover includes an outer circumferential wall that is another part of said circumferential wall of said housing, a bottom wall that is the other of said axially opposite end walls of said housing, and a mating surface that is provided by a distal end surface of said outer circumferential wall of said casing cover or provided in vicinity of said outer circumferential wall of said casing cover,
• wherein said stator core is fixed, at a casing-side end portion thereof that is said one of said axially end portions, to said bottom wall of said casing;
• wherein said casing and said casing cover are fixed to each other, with said mating surface of said casing and said mating surface of said casing cover being in contact with each other,
• wherein said vehicle electric motor comprises a positioning engagement mechanism establishing an engagement by which said casing and said casing cover are positioned relative to each other with said mating surface of said casing and said mating surface of said casing cover being in contact with each other such that an inner circumferential surface of said outer circumferential wall of said casing and an inner circumferential surface of said outer circumferential wall of said casing cover are coaxial with each other, and
• wherein said stator-core-inclination restraining portion protrudes from an inner circumferential surface of said outer circumferential wall of said casing cover, toward a casing-cover-side outer circumferential surface of said stator core, said casing-cover-side outer circumferential surface being said part of said outer circumferential surface of said stator core which is located on a side of said casing cover.
