Abstract: A relief valve comprises a ball body separated from a seat member when a pressure of a working oil from a supply passage exceeds a set pressure, and a ball-body support member biased by a biasing member and supporting the ball body. The ball-body support member comprises a holding recess portion for holding the ball body and a taper portion formed around the holding recess portion and inclined so as to become deeper toward the holding recess portion.

Abstract: An electric oil pump includes a motor including a motor shaft, a pump assembly including a vane pump driven by the motor to suction and discharge oil, and an inverter to drive the motor. The motor includes a rotor, a stator on a side outward from the rotor in a radial direction, and a motor housing containing the rotor and the stator. The motor housing includes a suction port through which the vane pump suctions oil from outside, and a discharge port through which the vane pump discharges oil to outside. The motor housing includes flat surface portions in a portion of an outer periphery thereof. The suction port and the discharge port are located in a first surface of side surfaces which are the flat surface portions of the motor housing and are parallel or substantially parallel to the axial direction.

Abstract: An electric pump provided with a pump unit configured to discharge working oil by being rotationally driven by an electric motor includes: a drive shaft configured to transmit rotational driving force from the electric motor to a rotor of the pump unit; a rotation-detection shaft provided coaxially with the drive shaft, the rotation-detection shaft being configured to be rotated together with the rotor; and a rotation detector unit configured to detect rotation of the rotation-detection shaft. The rotation-detection shaft has: an engagement portion configured to engage with the rotor; and a detection-target portion facing the rotation detector unit, and an outer diameter of the detection-target portion is set so as to be larger than an outer diameter of the engagement portion.
