Abstract
A rotor of an electric pump may include a body having an inner circumferential surface encircling a shaft; and a magnet located in a motor chamber of a storage space of the pump, and arranged so as to be (i) separated from an outer circumferential surface of the body with an interval in between and (ii) separated from a stator of the pump with an interval in between. The interval between the magnet and the body may communicate the motor chamber and a pump chamber of the storage space. The body may include a groove extending from an end of the inner circumferential surface of the body to the pump chamber. The rotor may further comprise a wall disposed in the interval between the magnet and the outer circumferential surface of the body and at a position being different from the groove in a rotation direction of the rotor.
