Abstract: A housing has a housing main body and an outlet port. The housing main body includes a cylindrical housing inner wall that defines an internal space therein. The outlet port fluidly connects the internal space and an outside of the housing main body to each other. The valve has a valve body rotatable about an rotation axis along a rotation axis of the cylindrical housing inner wall. The valve is configured to selectively open and close the outlet port depending on a rotation position of the valve. The housing inner wall is formed such that a distance between the housing inner wall and the axis of the housing inner wall varies in a circumferential direction.

Abstract: A method for manufacturing a stator for an electric rotary machine including a stator core formed by stacking a plurality of steel plates and a coil attached to the stator core, the method includes forming the steel plates, forming the stator core by stacking and fixing the plurality of steel plates with an adhesive, attaching the coil to the stator core, and changing a stack strength of the stator core, by deteriorating the adhesive such that a bending resonance frequency of the stator does not overlap with a pre-measured circular resonance frequency of the stator, the bending resonance frequency varying depending on the stack strength of the plurality of steel plates.

Abstract: A driving device unit includes an electric motor configured to drive a vehicle, a drive device accommodating the electric motor, and an electric motor control device configured to control the electric motor. The drive device and the electric motor control device are arranged side by side in a horizontal direction, and an electrical connection portion electrically connecting the drive device and the electric motor control device is disposed at a joining portion between the drive device and the electric motor control device, and the drive device and the electric motor control device include a first fixing portion that directly fixes the drive device and the electric motor control device in the vicinity of the electrical connection portion, and a second fixing portion that fixes the drive device and the electric motor control device via a stiffener at a position away from the electrical connection portion.
