点がある。 The above-mentioned connecting member is publicly known, and the diameter D nio of the small diameter portion of the stepped hole that receives the holding pin used for a link with a specific nominal diameter d o is one step smaller in nominal diameter than the link. The diameter of the retaining pin is smaller than that used for links with d o-1 . With a connecting member having such a configuration, when connecting the chain rigging to a connecting member of a specific size, instead of inserting the holding pin combined with the connecting member into the stepped hole and fixing it so that it cannot escape, the Due to this caution, there was a risk that a holding pin that would be combined with a connecting member one step smaller than the mounting member would be inserted into the stepped hole. For this reason, it becomes impossible for the holding pin to function as a standard that matches the inner width bi of the link with the correct nominal diameter, and chains and connecting members with different load characteristics are combined. . In other words, the known connecting elements have the disadvantage that the components can be mixed up when assembling the chain rigging.
本発明の目的は、径が小さすぎる保持ピンを用

ーン索具用連結部材を提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a connecting member for a chain rigging that does not cause the above-mentioned problems even when a retaining pin having a diameter that is too small is used.

は達成される。 According to the present invention, the diameter D nio of the small diameter portion of the stepped hole is made larger than one times f of the diameter D of the holding pin, and the connection accommodates a link whose holding pin has a nominal diameter d o+1 that is one step larger. This object is achieved by having guide heads at both ends which can be inserted into the small diameter portion of the stepped hole of the member.

付孔の外へ滑り出ることにある。 The advantage of the connecting member of the invention is that the diameter D nio of the small diameter part of the stepped hole is larger than the diameter of the undersized retaining pin, and that the retaining pin has a guide head at the end opposite the locking member. If a retaining pin that is too small is accidentally inserted into the stepped hole, the retaining pin will be automatically removed during handling of the mounting member. The problem lies in sliding out of the stepped hole.

It consists of 6. The diameter D nax of the large diameter portion 6 is slightly larger than 1.2 times the nominal diameter d o of the link, while the diameter D nio of the small diameter portion 5 is 1.2 times the nominal diameter d o of the link. It is equal to 1/2 of the sum of 1.2 times the nominal diameter d o-1 of the link of the chain one step lower. The nominal diameter of the link varies stepwise by a constant (f), and the constant (f) is preferably 1.125 to 1.35.
