Zusammenfassung:	PROBLEM TO BE SOLVED: To allow a working vehicle for an in-tunnel light to travel along the small-radius curved travel part of a guide rail. SOLUTION: Bogie roller devices E placed at the front and rear of a working vehicle along its traveling directiorl P are installed in such a way as to be turnabte about the axis (turning center C1 ) of an arm fulcrum shaft 16 provided at almost the longitudinal center of the frame of the working vehicle via a bogie arm 18, so that when the working vehicle travels at the curved travel part of a guide rail G, the bogie roller devices E are turned to go along a direction close to the direction of the tangent of the curved travel part of the guide rail G.
