摘要： PURPOSE:To improve the reliability by disposing a spherical convex portion at the center of a chain pin to be fitted in a spherical concave portion mounted at the center of the inner surface of a bush and setting the inside diameter of the bush larger than the outside diameter of the pin in a chain of a curved conveyer or the like. CONSTITUTION:A spherical convex portion 4a mounted at the central part of a pin 4 of a chain 1 and a spherical concave portion 6a mounted at the central part of a bush are fitted to each other. The inside diameter of the bush 5 outside the spherical concave portion 6a is set larger than the outside diameter of the pin 4 outside the spherical convex portion 4a. The spherical convex and concave portions 4a, 6a enable the pin 4 and the bush 5 bend within the vertical plane as indicated by an arrow A, bend within a horizontal plane as indicated by an arrow B and turn in a torsional manner with the axis of advancing in direction of an arrow C. Thus, excessive bending and torsion will not be produced to improve the durability of a chain and improve the reliability.
