Description of the Related Art In the goggles disclosed in Japanese Patent Application Laid-Open No. 9-173377, band insertion holes are formed at the outer ends of the pair of left and right eyecups. The insertion hole has an oval shape, and the radius of curvature near the inner end of the eyecup is smaller than the radius of curvature near the outer end. In the elastic headband used for this goggle, the radius of curvature of the portion that is passed through the insertion hole is the same as or slightly smaller than the relatively large radius of curvature near the outer end of the insertion hole. According to the description of the above publication, the headbands of such goggles are easy to move in the vertical direction relative to the eyecup, and therefore the fine adjustment of the face of the eyecup is easy.

It is connected by the member 4 and the headband 6 which hangs around the head. The lens member 3 is made of a hard plastic material, and the inner end portion 7 located in the vicinity of the nose of the eyeglass wearer is formed so that the connecting member 4 can be attached and detached. At the outer end portion 8 located near the back of the head of the eyeglass wearer, the headband 6 is passed through a band insertion hole 9 extending in the vertical direction in the figure. An annular face-contact pad 10 made of a flexible elastic material is attached around the lens member 3. The headband 6 is elastic and elastic, and the band 6 folded back in the insertion hole 9 to form a double layer is
They are bound by a binding tool 11 so as to keep them parallel to each other. Both free ends 12 of the band 6 are connected via a buckle 13 so as to be adjustable in length.

る。FIG. 2 is a view showing the outer end portion 8 of the lens member 3, and the cross section of the band 6 located in the insertion hole 9 is shown by an imaginary line. The opening of the insertion hole 9 is the lens member 3
Extending in a long manner between the inner and outer end portions 7, 8 of the outer end portion 1 and the inner end portion 16 having a relatively wide width W 1 near the inner end portion 7.
The outer part 17 having a relatively narrow width W 2 is provided near the position 8.

The minor axis 9 is the thickness of the band 6 and the major axis b is the width of the band 6. With respect to the preferred dimensions of the insertion hole 9 in the inner and outer end portions 7 and 8 of the lens member 3, that of the inner portion 16 is 50% to 100% of the long axis b, and that of the outer portion 17 is 3 of the long axis b.
It is 0 to 100%.

した当初の状態を長く維持することができる。When the band 6 and the insertion hole 9 are thus formed, the band 6 can move relatively freely when it is in the inner portion 16, and the length of the band 6 can be easily adjusted. It is possible (see 6A in FIG. 2). When the hydrous glasses 1 are worn and the band 6 is pulled rearward, at least a part of the periphery of the band 6 fits into the outer portion 17 and the mutual positions of the lens member 3 and the band 6 are fixed. Therefore, the lens member 3 and the band 6 do not move unnecessarily, and it is not necessary to repeat the adjustment of these positions while wearing the water glasses 1. If the cross-sectional shape of the band 6 has a relatively flat surface as in the illustrated example, once the flat surface is brought into contact with the body such as the head, the band 6 is twisted or displaced after that. Since it does not occur, the initial state of contact with the body can be maintained for a long time.

他に、円形や矩形等にすることができる。In the present invention, the insertion hole 9 can be extended in the front-back direction of the lens member 3. The cross-sectional shape of the headband 6 in the vicinity of the insertion hole 9 can be circular, rectangular, or the like other than the elliptical shape shown in the drawing.

It is fixed to the member. Therefore, the positions of the band and the lens member are stable while wearing the underwater glasses,
There is no need to readjust these positions.
