PURPOSE:To restrain the mechanical strength of a guide rail to the minimum and facilitate the laying work or the course change of the guide rail by linking vehicle-body side steering wheels steerably following the curve of the guide rail to movable members which are movable along the guide rail laid on the side of a traveling route via link mechanisms. CONSTITUTION:A guide rail 1 is laid on one side of a traveling route while a pair of trolleys 2 are movably supported on the guide rail 1. On the other hand, steering wheels 8a, 8b are revolvably provided in the front/rear portions on one side portion adjacent to the guide rail 1 on the bottom face of a vehicle body 4 while revolvably providing caster-type introducing wheels 9a, 9b in the front/rear portions of the other side portion on the bottom face of the vehicle body 4. Also, a driving wheel 1 which is rotated by a motor 11 is provided in the center portion on the bottom face of the vehicle body 4. The front and rear trolleys 2 and the steering wheels 8a, 8b are linked together by a pair of link mechanism 12, enabling the steering wheels 8a, 8b to be steered following the curve of the guide rail 1. |
