Claims

[Scope of utility model registration request]

A shoulder portion formed by forming a convex portion at the center of one side of the piece and a concave portion at the center of the other side, causing the convex portions of adjacent pieces to engage with the concave portions, and providing the convex portion and the concave portion. In a wristwatch band in which a shaft hole is drilled through the protrusion, and a mounting pin is inserted into the shaft hole to sequentially connect the pieces in a hinge-like manner, the diameter of the shaft hole drilled in the convex portion is matched with the diameter of the shaft hole drilled in the shoulder portion. A retaining ring, which has a diameter larger than the diameter of the shaft hole drilled in the shoulder, and whose outer diameter is larger and inner diameter smaller than the diameter of the shaft hole drilled in the shoulder, is loosely fitted into the shaft hole drilled in the convex part to prevent this slippage. A wrist watch band characterized in that a mounting pin formed by cutting a metal pipe vertically into a shaft hole drilled in the shoulder portion and having a C-shaped cross section is press-fitted into the retaining ring.
