PURPOSE:To prevent poor electrification by forming the contact face of a rail body with a collector ring into a recessed face which is the deeper the more on the center side in the width direction of said rail body and guiding and moving said collector ring which is energized toward an electrifying rail side, to the center side in the width direction of said rail body. CONSTITUTION:An electrifying rail unit which is installed on the lateral side part on the opposite side to a side which is brought into contact with the supporting frame of a guide rail for movably supporting a moving body, has plural electrifying rails L. Each of the electrifying rails L consists of a rail body 12 made of a conductive material and a holder 13 formed with a nonconductive material such as synthetic resin, etc., and the holder 13 has a pair of guard wall parts 13a which are projected from both lateral side parts of the rail body 12 toward a collector ring 14 side. In this case, the contact face T with the collector ring of the rail body 12 is formed into a recessed face which is the deeper the more on the center side in the width direction of the rail. Thereby, the collector ring 14 is always guided and moved to the center side in the width direction of the rail body 12, securely preventing poor electrification.
