されている。In the latter, a cushion formed by punching a sheet of foamed chloroprene rubber, foamed silicone rubber or the like is adhered to an eyecup with an adhesive, and an elastomer or silicone rubber molded by an injection molding method is used. There is one that is fitted or molded integrally with the eyecup by insert molding (molded cushion). In the case of this molded cushion, the strength of bonding becomes a problem. If the bonding is not performed properly, the cushion may fall off during use or a gap may be formed between the cushion and the eyecup, thereby reducing the watertightness of the swimming goggles. As a countermeasure against such a problem, the actual fair 7-1
A rib is provided in the groove of the cushion as in No. 7327, a groove narrower than the rib is provided in the flange portion of the eyecup, and the rib is press-fitted into the narrow groove to obtain a good contact state. There are also proposals for obtaining watertightness.
