ている。2. Description of the Related Art When a conventional chain cover is attached to a transmission chain, for example, it is used in Japanese Utility Model Publication No. 3-7478.
As disclosed in the publication, it is used for the purpose of preventing the scattering of contaminants such as oil applied to the chain or preventing it from adhering to clothes and the like. Japanese wish No. 49-40056
As disclosed in the specification of the Japanese Patent No. 128883) and the drawings, it is used for the purpose of a carrier plate on which a carrier is placed.

一対の外リンク間に抱持嵌着されている。For any purpose,
The chain cover is held and fitted between a pair of opposed outer links so as not to hinder the bending of the chain and the rotation of the link around the connecting pin.

らである。However, in the above-described conventional chain cover, when the chain cover is mounted on the chain, the inner links and the outer links are alternately connected in a chain by connecting pins, so that the outer links are connected. By mistake, the outer link outer surface of the two connecting pins that penetrate one inner link, that is, between the adjacent outer link ends connected by the inner link. It often happens that it is mounted between the protruding ends. This is because the pair of opposed side walls of the chain cover has a space for embracing and fitting between the outer surfaces of the outer links even if they are incorrectly installed.

き、該カバーの脱落の原因となる。However, if the chain cover is incorrectly attached as described above, when the chain bends, the outer link of the chain bends and turns to rub against the inner side surfaces of the pair of side walls of the chain cover which face each other. The inner surfaces facing each other are worn away, and the holding force of the chain cover is reduced to cause one of the accidents of the chain cover falling off. Also, due to wear elongation of the chain, the distance between the outer links in the longitudinal direction of the chain is separated, It interferes with the connecting pin end engaging portion formed on the side wall of the chain cover, and wear of the engaging portion reduces the chain cover mounting force, causing the cover to fall off.

着する外リンク上端縁干渉突部を形成したものである。In order to solve the above-mentioned problems of the conventional example, the present invention provides a mis-attachment interference projection on the inner surface of the chain cover, and in the case of mis-attachment, the projection is an inner link. Alternatively, a pair of chains facing each other at the central portion in the chain longitudinal direction on the inner surface of the web portion that connects the upper edges of the pair of opposing side walls of the U-shaped cross section of the chain cover that interferes with the outer link. Outer link inner side surfaces of the outer link that project between the inner side edges of the outer link, or the pair of inner link outer surfaces facing each other at both ends in the chain longitudinal direction of the connection corner between the web portion and the pair of opposite side wall upper edge edges. The outer link upper end edge interference protrusion is formed between the side faces by embracing and fitting.

Since the protruding inner link upper edge interference protrusion is formed, when the chain cover is directly attached to the outer link, the inner link upper edge interference protrusion is inserted between the ends of the adjacent inner links. In the case of erroneous attachment, the interference protrusion does not interfere with the upper end edge and interferes with the upper edge of the inner link.

Since the link top edge interference protrusion is formed, when the chain cover is directly attached to the outer link, the protrusion is inserted between both ends of the adjacent outer link and does not interfere with the outer link top edge, so that the chain is not attached incorrectly. In this case, the protrusion interferes with the upper edge of the outer link and cannot be mounted.

The protrusions 19A and 19B are inserted in the valleys between the adjacent ends of the outer links 7A and 7B. In the mis-attached state shown in FIG. 8, the protrusions 19A and 19B collide with the upper edges of the outer links 7A and 7B and interfere with each other, so that they cannot be attached. Therefore, in both the first and second aspects of the invention, the chain cover cannot be attached to the chain in the case of incorrect attachment.

Since a protrusion that is inserted into the valley between the adjacent ends of the link and that interferes with the upper edge of the link in the case of incorrect attachment is provided on the inner surface of the chain cover, special attention should be paid to the correct attachment of the chain cover to the chain. Even if you don't pay, you will not be able to install the product if it is attached incorrectly, so if you install it, all will be properly attached, and you can easily and extremely easily avoid attachment. The work efficiency can be dramatically improved, and the fatigue of the worker can be significantly reduced.
