Abstract
An electric oil pump apparatus includes a housing, an electric motor, an oil pump, a shaft, a first bearing, and a second bearing. The electric motor is housed in the housing. The oil pump is provided in the housing and positioned on a first side in an axial direction with respect to the electric motor so as to be adjacent to the electric motor, and includes a pump rotational element rotatable coaxially with a motor rotor. The motor rotor and the pump rotational element are fitted to the shaft to be rotatable together with the shaft. The first bearing is disposed on the first side with respect to the pump rotational element, and supports the shaft while allowing rotation relative to the housing. The second bearing is disposed on a second side with respect to the pump rotational element, and supports the shaft while allowing rotation relative to the housing.
