Abstract
An electric pump includes: a second housing and a first housing separated from each other in an axial direction; a stator portion that accommodates an annular coil portion; an outer rotor portion that is rotated based on a magnetic field generated by the coil portion, at a position on the inner side of the housings; and an inner rotor that is rotatably supported by a support shaft portion having an axis that is offset from that of the outer rotor portion, and that has an outer peripheral surface that is engaged with an inner peripheral surface of the outer rotor portion. The second housing is fitted onto the support shaft portion, to which the first housing has been fixed, from one side of the support shaft portion in the axial direction. As a result, the outer rotor portion and the stator portion are clamped between the first housing and the second housing from both sides in the axial direction.
