PROBLEM TO BE SOLVED: To provide a rear arm for easily conducting wiring work from a battery provided outside of the arm to a power unit provided inside of the arm without providing a through-hole having an internal diameter larger than the external diameter of a coupler in the arm. SOLUTION: An rotary electric machine 7 is mounted to the rear arm 3 in the rear end side wherein the rear arm 3 is rotatably supported at the front end side by the main frame of the two-wheeler in which the rear wheel is driven by the electric machine 7. The front end side of the arm 3 is divided into a plurality of component members and a notch is provided in the members at the division part, thereby forming an opening to pass the wiring electrically connecting a power source provided in the main frame side to the electric machine 7.
