However, the braking pad 35 is not limited to a rubber material, and may be deformed as much as any other material having elastic force.

The brake pad 35 may be indented with a surface in contact with the wheel 24. Therefore, when the brake pad 35 is in contact with the wheel 24, the wheel 24 that is completely in close contact with the outside of the wheel 24 and moves along the rail 10 may be fixed.

In addition, the brake pad 35 may have a protrusion 36 formed at one side thereof. The protrusion 36 is formed at the lower end of the braking pad 35. That is, the braking pad 35 may have a shape in which the lower end portion protrudes from the upper end portion. The protrusion 36 is interposed between the wheel 24 and the rail 10 when the brake pad 35 is in contact with the wheel 24. Accordingly, the wheel 24 may be completely fixed by the protrusion 36, and the protrusion 36 may serve as a wedge to prevent the wheel 24 from being pushed.

The display unit 37 can be easily identified by a method in which the inner side and the outer side are painted in different colors. Therefore, it is possible to easily determine whether the rail conveying apparatus 1 is fixed even at the lower portion of the rail conveying apparatus 1. For example, when the brake pad 35 is in contact with the wheel 24, the display unit 37 may protrude outward of the frame 20 to confirm that the rail transfer device 1 is fixed to the rail 10. . On the contrary, when the brake pad 35 is separated from the wheel 24, the display part 37 does not protrude outward of the frame 20, so that the rail feeder 1 is not fixed to the rail 10. have.
