Abstract
First and second connection mechanisms electrically connect power cables extending in the same direction to first and second electric motor neighboring to each other in the extending direction of the power cables, respectively. The first connection mechanism of the first electric motor is arranged in a radially outer portion, and the second connection mechanism of the second electric motor is arranged in a space between the electric motors. Since both the connection mechanisms are located on the opposite sides of a joint surface between the first and second casings accommodating the first and second motors, respectively, the first and second connection mechanisms can be components on the first and second casing sides, respectively. This structure can prevent increase in size in a rotation axis direction, and can improve assembly workability for the motors.
