PROBLEM TO BE SOLVED: To provide a positioning structure that does not have an effect on a flux passage, to provide a key structure capable of reducing the thickness of a motor housing so as to make a water jacket approach a motor (particularly stator external periphery), and to provide a water jacket structure capable of improving efficiency of cooling in the motor. SOLUTION: In the structure of the motor housing which fittingly fixes a stator of the motor having the stator and a rotor into the motor housing, the structure of the motor housing is characterized by having a guide groove formed at the external peripheral surface of the stator of the motor and a female screw located in a proper position of the motor housing which is externally engaged with the stator, and by positioning the stator and the motor housing by screwing a male screw into the female screw.
