される。 As a second step, a wire rod 2 made of egg or brass is inserted into the groove 1a (FIG. 2). The wire rod 2
Secure the space that will become the shaft hole in the product. For this purpose, a wire rod with a circular cross section and an equivalent diameter of the shaft hole is selected, and the bottom of the groove to be formed in the first step is formed into an arc suitable for accommodating the wire rod, and the side wall of the groove is formed into an eave shape. The length of the eaves portion 1b is selected to be suitable for wrapping around the wire rod 2 and abutting the tips of the eaves in a step to be described later.

A stainless steel bar with a cross-sectional shape is obtained (Figure 3). The above edge bending and cross-sectional shape forming are performed using die drawing similar to the first step.
Rolling or the like may be used as appropriate. As described above, the tips of the eaves surrounding the wire can be butted or a minute gap can be provided.

る。 As a fourth step, the shaped bar is immersed in a nitric acid solution. Stainless steel is insoluble in nitric acid, copper and brass are soluble in nitric acid, and the wire rods 2 on both sides wound around the bar are melted and removed. The rod material thus obtained is passed through a neutralizing solution and washed with water, and then used as a required rod material A for a chain material having a shaft hole 3 (FIG. 4). The cross section of the material is exemplified as the chain materials A' and A'' in FIGS. 6A and 6B, but other suitable shapes can be selected.
