A first housing and a second housing, which are separated in a shaft direction of the rotor so as to be faced, and install the stator and the rotor, are included; and a material of the stator core is different from a material of the housings, in a state where one end portion in axis direction of the stator core is contacted to the first housing, and the other end portion in axis direction of the stator core is contacted to the second housing; and a neighboring portion of a contact portion, at which the first housing is contacted to the stator core, and another neighboring portion of a contact portion, at which the second housing is contacted to the stator core, are connected by a connecting component in axis direction, of which material is the same as a material of the stator core, whereby the first housing and the second housing are connected each other; and the first housing and the second housing are faced each other in a state where a gap intervenes between the both housings. |
