A conventional example is shown in FIG. 12 (US Pat. No. 4,468,819). A flexible connecting member 61 having a U-shape in plan view is disposed between a pair of left and right goggle bodies 60, and a connecting member 61 is disposed at the opposite end of each goggle body 60.
1 is provided. An insertion hole 63 is formed in this mounting portion 62,
A plurality of protrusions 64 are provided at both ends of the attachment portion 62, and these protrusions 64 are selectively engaged with the communication holes 63. In addition, 65 is the goggle body 60
This is a rubber belt for wearing.

Furthermore, there is a conventional example as shown in FIG. 13 (US Pat. No. 4,264,987).

A connecting member 61 in the form of a strip is arranged between the pair of left and right goggle bodies 60, 60 in a manner substantially parallel to the front surface of the goggle body 60, and the connecting member 61 is disposed at the opposite end of each goggle body 60. A mounting portion 62 is provided for mounting the mount. The mounting portion 62 is formed into a U-shape in plan having a front wall 66 and a rear wall 67, and openings thereof are opposed to each other. This mounting part 62
Both ends of the connecting member 61 are overlapped on the rear surface of the front wall 66, and the overlapping portion is fixed by a fixture 68. This fixture 68 is attached to the mounting portion 62.
A screw shaft 69 is screwed onto the rear wall 67, and a push plate 70 is provided at the tip of the screw shaft 69 and abuts against the connecting member 61 so as to be able to move toward and away from the connecting member 61. By screwing together the screw shaft 69, the connecting member 61 is pressed against the front wall 66 via the push plate 70, and the ends of the connecting member 61 are fixed.

(Problem to be solved by the invention) In the conventional example, since the connecting member is flexible and U-shaped, when the goggles are worn, the goggle body is pulled in the direction of separation by the rubber belt, causing the connection The parts are also stretched. Therefore, when worn, the distance between them is shifted, resulting in poor adhesion to the face. Also, especially on the front of the goggle body,
In devices equipped with a corrective lens for correcting myopia or farsightedness, the center of the corrective lens must be aligned with the pupil of the eyeball, so if the distance between the goggle bodies is different when worn, this will cause problems.

In addition, in the conventional example, the connecting member is flat in the form of a strip, so there is no problem mentioned above, but the end of the connecting member is pressed against the front wall of the mounting part due to the screw engagement of the screw shaft, and is fixed. Therefore, if the screw shaft is screwed in too much, there is a risk of cracks occurring on the front and rear walls of the mounting part, and if the screw shaft is not screwed in enough, the goggle body may be pulled in the direction of separation. At this time, there is a risk that the end portion of the connecting member may separate from the attachment portion. Further, in the case of using screws, a tool is required for screwing together the screw shaft.
