ABSTRACT:
An electric pump uses an inner-rotor type, brushless DC motor. A casing of the electric pump is formed by a pump casing and a main casing. A sensor-stator assembly is disposed in a space between a side wall portion of the main casing and a can and is sealed with resin. A first elastic seal member is disposed, in a fluid-tight manner, between the can and the main casing. A second elastic seal member is disposed, in a fluid-tight manner, between the pump casing and the main casing. In this condition, the pump casing and the main casing are fixed together.
