Abstract: A power transmission device includes a case, a control valve, and an electric pump. The case has a first chamber that accommodates a power transmission mechanism, and a second chamber in which the control valve is arranged upright, with pressure regulating valves being aligned in a vertical direction. An axis of rotation of a motor of the electric pump is aligned in the vertical direction. The control valve and the electric pump are arranged in a direction of an axis of rotation of the power transmission mechanism. The electric pump has a first flange section where a first arm of a jig engages, and a supported section supported by a second arm of the jig. The supported section forms a circular basic cross-sectional shape in a plane orthogonal to the axis of rotation of the motor. The first flange section extends from an outer circumference of the supported section.

Abstract: In manufacturing of a first electroformed component and a second electroformed component having portions fitted to each other into close contact, after the first electroformed component is formed, the first electroformed component is used as a portion of an electroforming mold to form the second electroformed component. Using the first electroformed component as a portion of the electroforming mold to form the second electroformed component, the shape of the first electroformed component is transferred to the second electroformed component. As a result, multiple types of components differing in shape may be accurately manufactured concurrently in a series of manufacturing steps.
