[0002]

2. Description of the Related Art Many watch bands having a structure in which a plurality of metal bridges are connected are manufactured. A technical example 1: Japanese Utility Model Publication No. Hei 2-6816 has been proposed as such a watch band. A main piece body formed by bending a metal plate into a rectangular cylindrical shape and a connecting piece are sequentially connected by a hinge piece. A structure in which a spacer material is fitted into the opening is adopted. Technical example 1
By adopting the structure of the above, it can be manufactured relatively inexpensively, but since it is rotated with the hinge piece, the watch band has a "play" at the time of winding and a little improvement in the flexibility of movement In need.

FIG. 14 shows a second technical example. In the technical example 2, a pair of main pieces 1 arranged at both ends in the width direction of a band (watch band) are arranged at the center of the main piece 1 in the width direction and interposed in the length direction of the band. The connecting piece 2 is connected to the connecting piece 2 in a stepped manner by connecting pins 3. The main piece 1 has a non-penetrating mounting hole 1 a and the connecting piece 2 has a penetrating state. Through hole 2a
Is formed, and an end protruding when the connection pin 3 is inserted into the through-hole 2a is inserted into the assembling hole 1a, and integrated by "caulking" processing, "forcibly fitting" processing, "welding" processing, or the like. Assembling in a state is performed. In the second technical example, the connection piece 2 rotates around the connection pin 3 so that the movement at the time of winding can be made smooth.

[0004]

However, with the structure of Technical Example 2, it is necessary to control the fitting accuracy between the connecting pin 3 and the mounting hole 1a extremely strictly. For example, in the “caulking” processing technology, it is necessary to manage the degree of “play” with high accuracy because the fitting portion is caulked to eliminate the gap.
In the "forced fit" processing technology, the labor for inserting the connection pin 3 becomes large. In the technology for welding the end portion of the connection pin 3, management and management are performed so as not to disassemble the connection pin 3 while maintaining the inserted state. The work labor becomes large, and the workability is impaired in any case.

The present invention has been made in view of these circumstances, and has the following objects. Satisfy both the smoothness and economy of movement by using pins. Improving band assembly. Ensuring diversity in band design.

[0006]

The present invention constitutes most of a metal watch band except for a stopper and a portion to be attached to a watch, and includes a bottom plate whose longitudinal direction is set in the width direction of the band, A pair of mounting pieces having an outer portion erected at an end in the width direction, a pair of front pieces inserted between the pair of mounting pieces, and a connection arranged interposed between the front pieces; A piece, an assembly pin for connecting the front piece and the connecting piece,
A concave / convex engaging portion is provided between the assembly piece and the front piece to integrate them. A technology is employed in which the concave / convex engaging portion is constituted by a locking hole formed inside the assembly piece and a projection formed on the outer portion of the front piece and inserted into the locking hole. The assembling pin is inserted into the pin insertion hole of the front piece via the through hole of the connecting piece, and is attached to the pin insertion hole in a non-penetrating state. A technique in which an assembling piece is formed by pressing a metal plate material and has an outer plate and an inner plate formed by folding the metal plate material is applied.
