The present invention provides a power supply apparatus for long slide without drooping or bending a wire harness when a sliding structure is moved. The problems are solved by utilizing a power supply apparatus 1 for long slide including: a case 2 for receiving a wire harness 3 folded in a U shape; a slider 6 slidably engaged with the case, the slider holding a movable wire harness end; a timing belt 4 folded in a U shape along an inner surface of the wire harness and held with the slider at a movable end thereof; and a gear 7 engaged with the timing belt for supporting the wire harness, or a power supply apparatus 31 for long slide including: a gear 33 engaged with the timing belt 4 at a turn-around portion 3b of the wire harness 3; and a rotatable support portion 35 connected to the gear with a connection member 34 and contacting an inner surface of the timing belt.
