WRIST WATCH BAND ADJUST PIN, METHOD OF MANUFACTURING THE PIN, AND WRIST WATCH BAND CONNECTION STRUCTURE

摘要

An adjust pin (1) which connects a plurality of blocks (2) in chain-shape for forming a wrist watch band (3) is formed of a metal material having a superelastic area where a stress according to a variation in strain becomes a constant, wherein a bent part (5) is formed on the adjust pin (1) for acting a bending stress in the superelastic area on the inner surface of a connecting through hole (2a) in the block (2) under the state that the blocks (2) and (2) adjacent to each other are connected to each other, whereby, when the adjust pin (1) is inserted into the block (2) until the bent part (5) is positioned at the connecting through hole (2a), the bent part (5) provides a force acting due to a bending stress in the superelastic area to the inner wall of the hole so as to hold the adjust pin (1) securely by its spring force.
