１１９３７号公報参照）。Conventionally, there are two types of couplings for connecting chains, etc.
The ends of both arms of the two U-shaped fittings overlap each other, and between the arms of each U-shaped fitting, there is an annular protrusion y in the middle of the inner surface.
j! 0: A pin having a cylindrical spacer and having an annular groove on the outer periphery of the central portion in the longitudinal direction is inserted into each U.
It is inserted through the pin holes provided in both arms of the shaped metal fitting and the cylindrical spacer, and is placed in the annular groove of the annular protrusion,
A coupling is known in which the cylindrical spacer prevents the pin from being pulled out (Reference 1, 1983-
(See Publication No. 11937).

While holding the cylindrical spacer in a predetermined position between the two arms of each U-shaped metal fitting, it is necessary to insert the pin across the pin holes of both arms of each U-shaped metal fitting and the cylindrical spacer. The assembly operation is complicated, and since the pin and the cylindrical spacer are partially contracted before assembly, there is a risk that the small cylindrical spacer may be lost.

とかできる等の効果が得られる。According to this invention, a spring collar 5 having an outer diameter D2 slightly larger than the diameter Dt of the pin hole 4 of the arm of the U-shaped fitting 1 is fitted into the small diameter portion 3 provided at the intermediate portion of the pin 2. Since a gap 6 is provided between the inner surface of the spring collar 5 and the small diameter portion 3, when assembling the coupling, simply insert the pin holes 4 in each arm of the two U-shaped fittings 1. In the matched state, one side of the pin 2 is inserted into the pin hole 4 of one arm of the valley U-shaped fitting 1, and then the pin 2 is given a blow l.
By performing a simple operation such as pressurizing the spring collar 5 or applying strong pressure, the spring collar 5 is passed through the pin hole 4 of one arm of each U-shaped fitting 1 while visually deforming the pressure part. interposed between the arms of pin 2, and both sides of pin 2 /4
The spring collars 5 can be fitted into the pin holes 4 of the arms on both sides of the U-shaped metal fitting X1, and are fitted so as not to move in the longitudinal direction relative to the pin 2 when the camp ring is assembled. Since it is interposed between the arms on both sides of each U-shaped metal fitting 1, the engagement between the end of the spring collar 5 and the arms can reliably prevent the pin 2 from being pulled out. Furthermore, the moving platform for disassembling the coupling automatically presses the spring collar 5 by simply abutting a part of the bar against one end of the pin 2 and hitting or applying strong pressure to the other end of the bar. The pin 7 with spring collar can be easily removed due to partial deformation, and when the coupling is disassembled,
Since the spring collar 5 is fitted onto the pin 2 in such a way that it will not come off, it is possible to eliminate the risk of the spring collar 5 falling off or being lost.
