The present invention aims to prevent bending of a power supply arm in a width direction, resolve a rattling of a wire harness and instability of a trajectory, and increase bending resistance of the wire harness. In order to achieve the above object, there is employed an arm power supply device (1) in which a first arm (3) is rotatably and axially supported to a base member (2) having one harness fixing portion (14b), a second arm (8) having the other harness fixing portion (58) is rotatably and axially supported on a rotation tip side (6) of the first arm, the first arm includes an enclosure portion (5) forming a slit (4) through which a wire harness (28) is inserted, and the wire harness passes from the base member to the slit and is wired over the second arm. The enclosure portion (5) includes an inclined wall (36) to guide the wire harness (28) derived in a bent shape from the second arm (8) to be in contact with the inner surface. |
