のものが知られている。Conventionally, as a coupling for connecting a chain or the like, as shown in the seventh factor and FIG. A spring collar 9 for preventing the pin from being removed is interposed between the ends of the steel cylindrical body with a slit 4 extending over the entire length of the steel cylinder, and the pin 10 is inserted between both arms of each U-shaped fitting 1. A structure is known in which the spring collar 9 is inserted into a pin hole provided at the end, press-fitted to the spring collar 9, and the spring collar 9 is fixed to the pin 10 by pressure force.

スプリングカラー９に歪み割れが発生する恐れがある。However, in the case of the conventional coupling, when assembling the coupling, the spring collar 9 is interposed between the ends of both arms of each U-shaped fitting 1, and the pin 10 is inserted into the pin hole of the arm of the U-shaped fitting 1. While inserting the pin, the end of the pin is brought into contact with the inner edge of the spring collar 9, and then, while holding the spring collar 9, the pin 10 is struck with a hammer or pressed with a press-fitting tool to remove the pin. 1° into the locking spring collar 9, the pin group has to do all the work of press-fitting the locking spring collar 9 into the locking spring collar 9, so when press-fitting the pin, the pin group has to do the complicated work of holding the locking spring collar 9 strongly to prevent it from being blown off. This requires work, and since a pushing force is constantly acting on the spring collar, the spring collar 9 and pin 1 may become damaged after a long period of time.
There is a risk that the pin 10 may shift in the longitudinal direction relative to the spring collar 9 due to the weakened pressure contact with the spring collar 9, and furthermore, there is a risk that the spring collar 9 may be distorted and cracked.

８を非圧接状態で配置する。Next, the upper end of the pin 7 is struck with a hammer, or the pin 7 is strongly pressed downward with a suitable press-fitting tool, so that the pin 7 penetrates the stepped spring collar 5 and is inserted into the lower side. The small diameter portion 6 of the pin 7 is placed in the small diameter cylindrical body 2 of the stepped spring collar 5 in a non-pressure state by inserting it into the pin hole 16 of the folding arm 11 and the grooved arm 12, as shown in FIG. , the large diameter portion 8 of the pin 7 is disposed in the large diameter cylinder 3 of the stepped spring collar 5 in a non-pressure state.

得られる。According to this invention, the metal stepped spring collar 5, which is made up of a small-diameter cylinder 2 and a large-diameter cylinder 3 connected to both ends thereof, and is provided with a slit 4 extending over the entire length, is attached to each U-shaped metal fitting. The small diameter portion 6 of the pin 7, which is interposed between the ends of the pin 7 and has a small diameter portion 6 in the middle, is inserted into the small diameter cylinder 2 of the stepped spring collar 5 in a non-pressure state, and the stepped spring collar 5 Large diameter cylindrical body 3 in
Since the large diameter portion 8 of the pin 7 is inserted in a non-pressure state, no pushing force is constantly applied to the stepped spring collar 5, and therefore the stepped spring collar 5
Strain cracks do not occur in the pin 7, and the pin 7 can be pulled out due to the engagement between the step between the small diameter cylinder 2 and the large diameter cylinder 6 and the step between the small diameter part 6 and the large diameter part 8. You can reliably prevent it from coming out, and when assembling the coupling,
The stepped spring collar 5 is interposed between the arms of each U-shaped fitting 1, and the large diameter portion 8 of the pin 7 is inserted into the pin hole 16 of one arm of each U-shaped fitting 1 and one of the stepped spring collars 5. When inserted into the large-diameter cylinder B, the stepped spring collar 5 is held by its large-diameter portion 8, so there is no need for the worker to hold the stepped spring collar 5 by hand or with a tool when press-fitting the pin 7. Therefore, effects such as ease of assembling the coupling can be obtained.
