Abstract:
     Provided is a band link coupling pin capable of improving the operability of coupling and decoupling of any adjacent links, and capable of improving the reliability of coupling between the adjacent links. Provided is a link coupling pin in which a convex section (engagement section) including a second through hole is arranged in a concave section sandwiched by arm sections each including a first through hole to couple any adjacent links, and inserted into both first and second through holes. The coupling pin is made of a wire rod capable of changing in shape due to its elasticity to be smaller in diameter than the first and second through holes. At least one of each end section to be arranged in the first through hole of this pin and a middle part located in the second through hole forms an elastic deformation section being zigzag when viewed from the side. The elastic deformation section is so formed that the width at free state is made larger than the hole diameter of the first and second through holes, and at usage, is so formed as to elastically contact at least one hole inner plane of the first and second through holes.
