A heat sink has two heat radiation blocks. The heat radiation block is formed in a wide column shape. The heat radiation block has connection parts at both ends. The connection parts have respective holes formed to pass through in the axial direction of a motor. One screw is inserted in one connection part and threaded into a motor case. The other screw is inserted in the other connection part and threaded into the motor case together with a cover. A power module forming an inverter circuit of each of two power supply systems is arranged on each heat radiation blocks. |
