Power transmission device

A power transmission device, comprising:

• a case that accommodates a power transmission mechanism;
• a control valve configured to control an oil pressure supplied to the power transmission mechanism;
• and
• an electric pump configured to supply oil to the control valve, wherein
• the case has
• a first chamber that accommodates the power transmission mechanism, and
• a second chamber arranged adjacent to the first chamber in a horizontal direction,
• the control valve is arranged upright in the second chamber, oriented so that a plurality of pressure regulating valves are aligned in a vertical direction,
• the electric pump is provided in the second chamber so that an axis of rotation of a motor 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, and
• the first flange section extends from an outer circumference of the supported section.
