Claims

[Scope of utility model registration request]

A convex portion formed in the middle of a side edge of a piece is engaged with a concave portion formed on a side edge of an adjacent piece, and a shaft hole is drilled through the shoulder portion formed by providing this concave portion and the convex portion. The shaft hole of the convex portion is made larger in diameter than the shaft hole of the shoulder portion, and a retaining ring having an outer diameter and a smaller inner diameter than the diameter of the shaft hole of the shoulder portion is loosely inserted into the shaft hole of the convex portion. In a wrist watch band in which the pieces are connected sequentially in a hinge-like manner by inserting and fixing the mounting pin into the retaining ring through the shaft hole of the shoulder part, an axial part protruding inwardly in the axial middle of the metal pipe is used. A wristwatch characterized in that the retaining ring is formed by forming a protrusion, the mounting pin is a metal round bar having a hardness lower than that of the metal pipe, and the mounting pin is press-fitted into the retaining ring. Band for use.
