にオフセントリンクを用いない連結装置に係わる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coupling device for an odd-numbered transmission chain, and particularly to a coupling device that does not use off-cent links.

リンクプレート２との間にワシャＷが介装されている。When a transmission chain is constructed with an odd number of links, offset links are usually used, but since offset links have a bend in the center, they not only easily deform due to chain tension and cause pinch errors, but also Depending on the processing, stress concentration may occur, reducing fatigue strength.
Furthermore, if the cross-sectional area of the link plate is large in a strong chain, the bent portion may interfere with the adjacent link and may not be installed. Therefore, a connecting device that does not use an offset link, which has the above-mentioned drawbacks, is disclosed in Japanese Utility Model Publication No. 17662/1983. In this connecting device, as shown in FIG. 1, a washer W is interposed between a roller link plate 1 and a pin link plate 2 that are connected by a long pin P.

に関しては無力というよりは寧ろ有害である。Therefore, the pin P is prone to bending deformation due to the gap between the link plate 1.2 and the washer W, and in that case, the link plate 2 will warp, causing stress concentration around the pin hole of the link plate 2. or reduce fatigue strength. Therefore, the washer W merely serves to prevent the link plates 1 and 2 from slipping laterally, and is more harmful to the strength of the pins and the link plates than is powerless.
