In the disclosed embodiment, the restriction protrusion 24c is press-fitted into the restriction recess 16h. Modification example

In the chain guide device 10 described above, the chain guide 16 is made of a single plate member that is appropriately bent and coupled at its bottom. However, the chain guide 16 can also be made of two plate members. In this case, each plate member has a first lateral portion and a second lateral portion. Also, the two plate members will typically be coupled at their bottom. Also, each of the two plate members may have a first bridge portion corresponding to the first bridge portion 16c shown in the drawings. In this case, each of the first bridge portions may have a restricting concave portion 16h as shown in FIG. 2, and the restricting convex portion 24c may extend through the two restricting concave portions. Correspondingly, as seen in Figure 2, the two first bridges will be configured to be substantially parallel. In addition, the two first bridge portions and pillow members will be accommodated between the flange 22b of the locking pin 22 and the riveted portion 22d. As a result, the pillow member 24 and the two plate members of such a two-piece chain guide 16 can be coupled in a non-rotatable manner and particularly efficiently. This can be achieved by the extension of the locking pin 22 through the protrusions 22e of the two first bridges and the pillow portion in combination with the extension of the pillow member through the two limiting protrusions 24c of the two first bridges.

When the first bridge portion 16c shown in FIG. 2 has a restriction protrusion extending to the restriction recess formed in the pillow member 24, a similar effect can be obtained. The restriction recess of the pillow member can be formed as a through hole. In the two-piece chain guide as described above, the restricting convex portion of the upper first bridge portion will additionally extend through the restricting concave portion formed as a through hole in the lower first bridge portion.

At least one of the riveted portion 22d and the flange 22b may be replaced by a structure including a groove 22c for coupling the upper portion of the pin 22 and a gasket 28 as shown in FIG. 2. In addition, the structure located at the upper part of the coupling pin 22 may be replaced by a flange at 22b in the middle part of the coupling pin 22 as shown in FIG. 2, or may be replaced by a flange at 22b as shown in FIG. The riveted part at 22d in the lower part of the pin 22 is replaced. Finally, the riveted part can be replaced by a flange.

The pillow member 24, the first additional pillow member 26, and the second additional pillow member 36 may be made of rubber materials instead of resin materials. In addition, at least one of the first additional pillow member 26 and the second additional pillow member 36 may be omitted from the chain guide 16.
