A tangling prevention member 53 and a holding portion 6 for holding the temple body 4 are provided.
As shown in FIG. 1C, the rear end portion of the bending member 51 has a concave cross-sectional shape downward, and the shaft member 54 bridges both side surfaces of the concave shape.

The ear contact member 52 includes a swinging portion 52d having a through hole penetrating through the shaft member 54 disposed at the rear end portion of the bending member 51 in the middle of the curved portion of the ear contact portion 52a. ing. Since the through hole of the swinging portion 52 d is penetrated by the shaft member 54, the ear pad member 52 can swing around the shaft member 54.
The structure in which the ear pad member 52 is attached to the rear end portion of the bending member 51 is not limited to the above-described structure, and any structure can be used as long as the ear pad member 52 is swingably attached to the rear end portion of the bending member 51. It may be a structure. For example, the ear pad member 52 may include a shaft member, and the rear portion of the bending member 51 may include a through hole that penetrates the shaft member.

  The entanglement preventing member 53 and the ear pad member 52 are integrally formed. The front end portion of the entanglement preventing member 53 is fixed to the predetermined portion 52b with a screw 55. The entanglement preventing member 53 may be fixed to the predetermined portion 52b by other methods such as adhesion. The entanglement preventing member 53 is an elastic member. For example, various elastic members such as a leaf spring formed of an elastomer (a high-molecular substance having elasticity such as natural rubber or synthetic rubber) or a shape memory alloy can be used. . In the present embodiment, the ear pad member 52 and the entanglement preventing member 53 are the same material and are integrally molded. However, the ear pad member 5 and the entanglement preventing member 53 are separate materials or the same material. It may be joined by bonding or screws.

  As shown in FIG. 1 (d), the holding portion 6 opens in the direction of the temple body 4 and holds the temple body 4 by a concave groove shape extending in the front-rear direction. Two opposing sandwiching surfaces 61, 61 in the shape of a concave groove sandwich the temple body 4. Thus, the clamping part 6 clamps the temple main body 4 from the direction perpendicular | vertical to the front-back direction. The holding part 6 has elasticity, and is made of, for example, a flexible resin. The temple body 4 is made of, for example, flexible resin or metal. The distance t1 between the holding surfaces 61 and 61 when the fixture 5 is detached from the temple body 4 is shorter than the thickness t2 of the temple body 4 on the held surface 42.

When attaching the fixture 5 to the temple body 4, the lower end 43 of the temple body 4 is pressed against the upper end of the side surface portion 63 of the holding portion 6 to open the opening 62, and the fixture 5 is pushed in the direction of the temple body 4. . The side surface portion 63 of the holding portion 6 opens outwardly by elasticity, the lower end portion 43 of the temple body 4 enters the groove shape, and the fixture 5 is attached to the temple body 4. After the fixture 5 is attached to the temple body 4, the temple body 4 is clamped by the elasticity of the clamping part 6.
When removing the fixture 5 from the temple body 4, the fixture 5 may be pulled away from the temple body 4. When the pulling force exceeds the pinching force of the pinching portion 6, the fixture 5 can be removed.

Next, two postures of the ear contact portion 52a switched by the entanglement preventing member 53 will be described with reference to FIG. FIG. 2 is a side view of the spectacle frame 2 showing two postures of the ear contact portion 52a, and FIG. 2 (a) shows a posture in which the front end portion 52c of the ear contact portion 52a is pressed against the bending member 51 side. FIG. 2B is a side view in a posture in which the front end portion 52 c of the ear contact portion 52 a is separated from the bending member 51.
Since the entanglement preventing member 53 is formed of a flexible elastic member, the elastic force Fa is provided on the side where the front end portion 52c of the ear contact portion 52a is closer to the bending member 51 than the switching point with a predetermined position as the switching point. As shown in FIG. 2A, the front end portion 52c of the ear contact portion 52a is held at a position pressed against the bending member 51 side. On the other hand, when the front end portion 52c of the ear contact portion 52a is located at a position away from the bending member 51 from the switching point, the entanglement preventing member 53 bends to reverse the direction in which the elastic force acts, and the elastic force Fb acts to hold the front end portion 52c of the ear contact portion 52a at a position away from the bending member 51 as shown in FIG.

  Accordingly, when the user wears the spectacle frame 2, the front frame 3 is placed in a posture (FIG. 2B) in which the front end portion 52 c of the ear contact portion 52 a is held at a position separated from the bending member 51. 2 and the rear end portion of the ear pad member 52 are wider than the distance L1 in FIG. 2A, so that the ear pad member 52 does not get in the way (the ear pad member 52 can be Can be installed easily (without holding down). Then, by contacting the ear, the posture of the entanglement preventing member 53 is switched to a posture (FIG. 2A) in which an elastic force Fa is applied to press the front end portion 52c of the ear contacting portion 52a toward the bending member 51 side. The rear end portion of the ear contact portion 52a can be firmly contacted with the back side of the ear, and the spectacle frame 2 is difficult to slip off.

  Further, when removing the spectacle frame 2, the rear end portion of the ear contact portion 52 a is pressed rearward with a finger so that the entanglement preventing member 53 is in the posture of the front end portion 52 c of the ear contact portion 52 a. It switches to the attitude | position (FIG.2 (b)) which applies the elastic force Fb pressed to the position spaced apart from the side, and the spectacles frame 2 can be removed easily. At this time, since the space between the bending member 51 and the front end portion 52c of the ear contact portion 52a is blocked by the entanglement preventing member 53, the hair hardly enters the attachment portion between the bending member 51 and the ear contact portion 52a. Thus, the entanglement of the portion is suppressed.

  In this way, since the entanglement preventing member 53 can switch the posture of the ear contact portion 52a by its elastic force, the spectacle frame 2 can be mounted more easily and the omission of the spectacle frame is more effective. Can be suppressed.

  In this embodiment, an example in which the fixture 5 is attached from below the temple body 4 is shown. However, for example, from either the left side or the right side of the temple body 4 from any side of the temple body 4. The attachment 5 may be attached.
