板間の距離が大きい為に大きな隙間を生じ、これ
によりガタツキを生じるという問題がある。(Prior art and problems) Conventional roller rails have a number of roller mounting holes in the top plate of the roller frame, and the rollers are detachable so that the roller shafts are forcibly fitted into bearings formed on the side plates of the frame. However, since the bearing part is formed with a hole that passes through the side, dust can easily enter from the side, and since it does not have a guide part for inserting the roller, it takes time and effort to insert the roller. Since the distance between the left and right side plates of the frame is large relative to the roller width, a large gap is created, which causes a problem of wobbling.

Roller fitting holes 2, 2... are arranged in a row at a predetermined interval in the longitudinal direction on the top plate 1a of the rail stand 1, which is formed by bending a metal plate into a downward U-shaped cross section, and the left and right sides of each roller fitting hole are provided. A guide part 4 consisting of a notch that opens upwardly at the center of the guide part 4, followed by an insert part 3 with an interval d' smaller than the roller shaft diameter d below the guide part 4, and a step-shaped outward protruding part whose side surface is integrated with the rail base side plate 1b. The shaft 6a of the roller 6 fitted into the roller fitting hole 2 is fitted into the bearing part 5, and the lower half around the bearing part 5 is formed in series. An annular rib 8 is formed on the rail base side plate 1b by inwardly protruding it so that the roller end face 6b' comes into line contact with the rail base side plate 1b.

右方向の遊動、ガタつきが阻止される。 The rail stand 1 consists of a top plate 1a made of a metal plate formed into a downward U-shape, left and right side plates 1b, and a mounting base piece 1c with the lower ends of the side plates bent outward. Roller fitting holes 2, 2, . . . consisting of rectangular holes are provided with a small amount remaining. At the center of both left and right sides of the fitting hole 2, a notched concave guide portion 4 is formed which is continuous with the fitting hole 2, and furthermore, the left and right side plates 1b facing below the fitting hole 2 are pressed outward to protrude in a stepped shape. The circular recessed bearing part 5 is formed integrally with the guide part 4, and the inserting part 3 is formed integrally with the guide part 4 at a distance d' which is slightly smaller than the shaft diameter d of the roller shaft 6a. When inserting the roller 6, first insert the roller 6.
When the shaft 6a is inserted into the insertion hole 2 and the shaft 6a at both ends is placed on the guide part 4, it is supported by the inserting part 3. However, if the roller is forcibly pressed downward from above at that time, the inserting part 3
It is forced to pass through and is fitted and supported by the stepped bearing part 5. Therefore, from then on, the roller 6 will not be removed upwardly from the bearing portion 5 without permission. When the roller 6 is forcibly pressed from below, the inserted part 3 is spread and passed, and the roller 6 can be extracted. In addition, in the fitted and supported state, the end surface 6a' of the shaft 6a of the roller 6 is suppressed by the inner surface of the end plate 7, so that the shaft 6a of the roller 6 is prevented from moving or rattling in the left-right direction.

きる。(Effects) The present invention has the above-mentioned configuration, and when the roller 6 is installed in the roller fitting hole 2 of the rail base 1, the roller shaft 6a is attached to the upwardly expanding guide portion 4,
4, and is forced to pass through the sandwiched parts 3, 3 while spreading them apart, and is easily and quickly correctly fitted into the bearing part 5, and the side surface of the bearing part 5 is closed by the end plate 7. This prevents dirt and dust from entering from the sides as well as oil leakage and dirt from the inside, and the end surface 6b' of the roller 6 fitted in the bearing part 5 is in line contact with the annular rib 8, so that it is prevented from entering from both sides. Since it can be suppressed, it is possible to completely eliminate side-to-side wobbling and allow the rollers to rotate smoothly and easily.It has a simple structure, is durable, has little material loss, is inexpensive, and is easy to implement. A positive effect can be expected.
