摘要：
A power transmission device that includes a clutch that transmits power from a motor to an axle; a first pump that is driven by power from the motor to generate and output fluid pressure; a second pump that receives and is driven by a supply of electric power to generate and output fluid pressure; a line pressure generating valve that is operated by operation fluid input to an operation input port, and regulates fluid pressure output from the first pump to generate a line pressure for engaging the clutch; and a switching valve that switches between a first connection state and a second connection state.
