FIG. 4 is a diagram showing a cross section when cut, and (d) is a diagram showing a cross section when cut along the BB cutting line.

The connecting belt 3 includes a flat belt 30, a binding ring 31, and stoppers 32 and 33. The binding ring 31 and the stoppers 32, 33 are integrally formed with the flat belt 30 and are made of the same material.

The connecting belt 3 is made of a material having appropriate flexibility and elasticity. For example, it can be manufactured by hot pressing silicone rubber with a hardness of 50 degrees. Moreover, other synthetic rubbers and other synthetic resins can also be used.

The flat belt 30 is a connecting member having a substantially rectangular flat cross section, and has an elongated shape extending in the longitudinal direction with a constant width except for the vicinity of the end 302 on the opposite side from the binding ring 31. For example, it has a shape of 20 mm in width, 2 mm in thickness, and 220 mm in length. Of both longitudinal ends of the flat belt 30, the end 301 provided with the binding ring 31 will be referred to as the "ring end", and the opposite end 302 will be referred to as the "insertion end". .
