2. Description of the Related Art FIGS. 17 to 19 show a conventional example, and 1a shows a non-slip body attached to a tread surface of a metal tread plate 4a.
The conventional non-slip body 1a is entirely made of rubber or elastomer, and as shown in FIGS. 17, 18 and 19,
The step board 4a is formed in a bag shape so as to surround it, an opening 6a is provided at the center of the bottom surface, and a fitting groove 8a is formed inside the opening 6a so as to fit with the outer edge of the step board 4a. Reference numeral 5a denotes a non-slip groove. As described above, since the entire body is conventionally made of rubber or an elastomer, when the anti-slip body 1a is molded, when the mold is removed from the mold, the fitting groove 8a bites into the mold so that it is difficult to remove, and the temperature is still high. There was a problem in work such as forcible removal in a soft state. Also, when attaching the non-slip body 1a to the tread plate 4a, it is difficult to attach the non-slip body because the peripheral edge of the opening 6a is spread and attached, and considerable power, stiffness and skill are required.
