The lens 12 has a locking recess 14b at a position spaced from the through hole 14a by a predetermined distance. In this embodiment, the locking recess 14b is formed by, for example, a small cylindrical hole provided near the through hole 14a. In this case, the lens 12 is moved from the center of the locking recess 14b.
The distance to the peripheral edge of the through hole 14a is, for example, 1.5
mm. The locking recess 14b is
And extends substantially vertically from the one main surface to the other main surface by a predetermined depth. The depth of the locking concave portion 14b is formed to be substantially the same as the length of a locking convex portion 44 of an adjusting member 40 described later that is locked by the locking concave portion 14b.

The lens 12 is disposed on one principal surface side of the lens 12 and functions as a connecting member with the temple T. The lens 12 is disposed on the other principal surface side of the lens 12 and has a through-hole 14 a of the lens 12. And the fastener 18 inserted therethrough. Furthermore, Temple T of Satoshi 16
An adjusting member 44 is detachably formed at a distal end portion opposite to the side so that a locking convex portion 44 described later is appropriately locked to the locking concave portion 14b of the lens 12.

The tongue 16 is formed, for example, in a substantially L-shape in plan view, and has one end rotatably supported by a connecting end of the temple T by a hinge 20 (not shown) or the like. The wisdom 16 includes, for example, an oval plate-shaped lens holding portion 22 connected to the other end. On one main surface side of the lens holding portion 22, an insertion columnar body 24 is formed substantially at the center. The insertion columnar body 24 includes the lens 12 and the lens holding portion 22.
And is formed at a predetermined interval from the other end of the wisdom 16 to one end thereof. The insertion columnar body 24 is formed, for example, in a columnar shape with an elliptical bottom surface, and

3a and 23b.

In this embodiment, for example, the center of the through hole 14a of the lens 12 is located at a position 3.0 mm from one end in the length direction of the lens 12. The length of the long axis of the lens holding portion 22 is formed to be about 5.0 mm. In this case, the lengths of the lens contact surfaces 23a and 23b in the longitudinal direction are each 1.0 mm.
mm. Further, the length of the long axis of the insertion columnar body 24 is 3.0 to 3.5 mm, and the length of the short axis is 1.8 to
It is formed to have a length of 2.3 mm and an axial length of about 1.5 mm. Since the size of the diameter of the through hole 14 a of the lens 12, that is, the length of the long axis and the short axis is formed slightly longer than that of the insertion column 24, the insertion column 24 is connected to one side of the lens 12.

At one end in the axial direction of the fixing portion 28, for example, a hemispherical head 30 having a function as a fastening portion is formed integrally. The head 30 has, for example, a linear or cross-shaped groove 30a on its surface. In the present embodiment, the outer diameter of the fixing portion 28 of the fastener 18 is formed to be, for example, about 1.2 to 1.4 mm. In addition,
In the present embodiment, a round cross-recessed screw is used as the fastener 18. However, other than that, a round flat, flat, pan,
A round screw, a flat screw, or the like may be appropriately used.

Further, an adjusting member 40 is detachably formed at the tip of the lens holding portion 22 of the lens 16. The adjusting member 40 particularly includes, for example, a bottomed cylindrical cap portion 42 as shown in FIG. The cap portion 42
An intermediate portion in the axial direction has a locking projection 44 made of, for example, a columnar pin. The locking projection 44 is provided with the cap 4
2, the cap portion 42 is located near the bottom surface portion 43 in the axial direction.
Is provided to extend outward from the peripheral side wall surface of the second member. Locking projection 44
Is provided to extend in a direction orthogonal to the axial direction of the cap portion 42. The diameter of the bottomed hole 42a of the adjusting member 40 is
The lens holding portion 22 has a diameter substantially equal to or slightly larger than the diameter of the lens holding portion 22. Therefore, the adjustment member 40

Co-rotation with the tool 18 can also be prevented. In addition, since the contact member 32 is disposed between the head 32 of the fastener 18 and the surface of the lens 12, the head 30 of the fastener 18 can be brought into close contact with the surface of the lens 12. In this case, since the contact member 32 is formed of a relatively flexible material, it is easy to adhere to the shape of the lens 12 surface. Further, since the friction surface between the close contact member 32 and the lens 12 surface is increased, the fixing portion 28 of the fastener 18 is also prevented from loosening. Therefore, the lens 12
Is held between the lens holding portion 22 of the wisdom 16 and the contact member 32, and is firmly held. At this time, the lens contact surfaces 23a and 23b of the lens
The close contact surfaces 2 are in close contact with one main surface and the other main surface of the lens 12, respectively, so that the lens 12 is firmly held therebetween.

Insertion columnar member 24 provided on lens holding portion 22 of tomo 16
The distance between the control member 40 and the locking projection 44 of the adjustment member 40 can be changed as appropriate. Therefore, in the present embodiment, the mounting positions of the lens 16 and the lens can be easily adjusted despite the simple structure.

In the embodiment shown in FIGS. 1 and 2,
The lens 12 is not only held by the cooperative action of the insertion column 24 and the fastener 18, but also
Since the lens 12 is also held by the locking projection 44 of the adjustment member 40 fitted and locked to the lens 4b, the contact surface between the lens 16 and the lens 12 is increased, and the lens 12 is more firmly held without rattling. It can be securely held. In this embodiment, even if the lens contact surface 23b on the tip side of the lens holding portion 22 is omitted, the other lens contact surface 23a
The lens 12 can be held by the cooperative action of the lens 12 and the fastening member 18 and the contact member 32, but it is more preferable to include the two lens contact surfaces 23a and 23b as in this embodiment. Although not shown in FIGS. 1 and 2, the other lens (not shown) is also attached to the other lens (not shown) by the same eyeglass attachment structure 10.
