Claims

[Scope of utility model registration request]

(1) In a chain link in which a stand is installed between both sides of the inner hole of the ring so that both end faces of the stand are in contact with each other,
The above-mentioned stud is configured to have an axial cross-sectional shape such that the contact area with the chain link is large, and the periphery of the contact surface of the above-mentioned stud with the chain link is chamfered in a curved manner. It is characterized in that the central portion of the surface is formed into a convex shape having a rounded apex and continuous lines.

(2) A utility model registration request characterized in that the cross-sectional shape of the axis where the stud has a large contact area with the chain link is approximately rectangular, a laterally elongated ellipse, or a polygon. Chain link described in scope 1.

(3) A claim for utility model registration characterized in that the curved chamfer around the contact surface of the stud is a curved chamfer with a curvature at least equal to or greater than the depth of bite into the chain link. Chainlink described in item 1 or 2 of the scope.

(4) Registration of a utility model characterized in that the convex shape of the central part of the contact surface, which has a rounded apex and is formed by a continuous line, is a convex shape consisting of a part of a circular arc. Chain link according to claim 1, 2 or 3.
