2. Description of the Related Art Conventionally, a traveling rail laid under a conveyor chain in a conveyor is formed by, for example, machining or extrusion, while a frame on which the traveling rail is mounted is made of, for example, iron or steel. A stainless steel thin plate which is appropriately bent is used. The mounting of the traveling rail on the frame is, for example, appropriately placing the traveling rail on the frame and fixing the traveling rail to the frame at appropriate intervals along the longitudinal direction using a plurality of fixing screws, As shown in FIG.
The running rail 30 formed by extrusion molding is fitted and mounted on the flat edge portion of the frame 31, and the running rail 30 is mounted so as to sandwich the edge portion of the frame 31 by the elastic clamping pressure of the running rail 30 itself. 3
Means for fixing the end of the frame 0 to the frame 31 using a fixing screw has been employed.

[0003]

However, in the mounting means as described above, as the running rail wears,
Part of the fixing screw (for example, the head) is exposed and comes into contact with the conveyor chain sliding surface, causing abnormal wear on the conveyor chain, uneven transport speed, and abnormal noise. There were difficulties. Further, when the frame is mounted so as to sandwich the frame by the elastic clamping pressure of the traveling rail itself, if the elastic clamping pressure is weak, there is a possibility that the traveling rail may be laterally displaced with respect to the frame. Furthermore, if the elastic clamping pressure is strong, it is difficult to mount the running rail to the frame smoothly, and there is a possibility that the running rail cannot be mounted so as to be pushed into a predetermined position of the frame. There is a problem that the movement is not performed smoothly and heat, abnormal wear, vibration and noise are generated.
