To provide the miniaturized and simplified structure for applying a moving force to a moving body without setting the initial speed at a high level and capable of applying the moving force without applying an impact and to be easily used for a route for supporting and carrying a material to be carried while restricting the generation of noise.

The moving body 10 can move on a specified route 5 being supported and guided by a rail 3, and the moving body 10 has a support part 40 for a material to be carried, and a main body 11 side thereof is formed with a passive surface 15 directed to a side. A moving body feeding means 70 having a driving belt 71, which can freely abut on the passive surface 15, is arranged in a set route 5d of the specified route 5. Moving force can be sufficiently and securely applied to the moving body 10 by the moving body feeding means 70 in the set route part 5d.
