[Example]
<Glasses 100>
First, with reference to FIGS. 1 and 2, the overall structure of the glasses 100 to which the present embodiment is applied will be described. FIG. 1 is an overall configuration diagram of the glasses 100 to which the present embodiment is applied, and FIG. 2 is a perspective view for explaining the configuration of the front 140 to which the present embodiment is applied.

As shown in FIG. 1, the spectacles 100 is an example of eyewear and includes a pair of lenses 110 and a frame 120. In the present embodiment, the lenses 110 are described as a pair, but the lenses do not necessarily have to be a pair. Further, in the present embodiment, the lens 110 is described as the configuration of the glasses 100, but the lens 110 itself is not necessarily the configuration required for the glasses 100.

The frame 120 includes, for example, a front 140, a pair of temples 180 rotatably connected to both left and right ends of the front 140, and a pair of modern 160s attached to the rear side of the pair of temples 180. ing. Further, the frame 120 holds a pair of lenses 110 and holds the lenses 110 and the front 140 in an appropriate posture with respect to the user's eyes and head.

The front 140 supports a pair of lenses 110. The temple 180 presses the user's temporal region together with the modern 160 to sandwich this portion. In addition, the modern 160 contacts the upper part and the rear of the user's ear to prevent the glasses 100 from falling. The modern 160 is not necessarily a configuration required for the glasses 100.

In the following description, for convenience, the longitudinal direction of the front 140 shown in FIG. 1 is referred to as the "left-right direction" which is an example of the second direction. Further, when the glasses 100 are worn, the left side (right side in FIG. 1) seen from the user is referred to as the "left side", and the right side seen from the user (left side in FIG. 1) is referred to as the "right side". Further, the lateral direction of the front 140 is defined as the "vertical direction" which is an example of the first direction, and the thickness direction of the front 140 is defined as the "front-back direction".

The glasses 100 to which the present embodiment is applied are formed symmetrically with respect to the glabellar portion (bridge) 142, which will be described later. Therefore, in the following description, the left-right symmetrical configuration will not be distinguished, and only the configuration on either side of the drawing will be described by adding a reference numeral.

The front 140 has, for example, a plate-like structure extending in the left-right direction, and is curved so as to project forward along the user's face. Further, the front 140 includes a central eyebrows 142, a pair of nose pads 144 attached to the left and right sides of the back surface of the eyebrows 142, and a pair of rims 146 formed on the left and right ends of the eyebrows 142. It has a pair of twists 147 formed at each end of the pair of rims 146 and a pair of first hinge portions 148 attached to the back surface of the pair of twists 147.

The glabellar portion 142 connects the left portion and the right portion of the front 140 (glasses 100). Further, the glabellar portion 142 is, for example, a curved plate-shaped member, and is formed of resin or the like.

The nose pad 144 supports the front 140 by sandwiching the user's nose from both sides, and maintains the height of the front 140 with respect to the user's eyes. Further, the nose pad 144 is a clings type having, for example, a resin pad portion 144a and a metal support portion 144b. The deformation of the pad portion 144a and the support portion 144b allows the front 140 to finely adjust the posture of the user with respect to the nose and eyes (for example, the distance between the corneal vertices).

The rim 146 holds the lens 110. Further, the rim 146 is, for example, a ring-shaped member formed along the shape of the lens 110, and is formed of a resin or the like.
The first hinge portion 148 is formed on the Yoroi 147. Further, the Yoroi 147 is, for example, a curved plate-shaped member, and is formed of a resin or the like.

The first hinge portion 148 functions as an example of the connecting portion, and the temple 180 can be rotated with respect to the front 140 by combining with the second hinge portion 230 having a plate shape formed on the temple 180 side. It is connected to. That is, the first hinge portion 148 and the second hinge portion 230 constitute a hinge.
Further, the first hinge portion 148 is formed of, for example, metal or the like, has a semicircular shape when viewed from the vertical direction, and penetrates the central portion of the semicircular shape in the vertical direction through the first hinge portion 148. A screw hole 148h is formed. This screw hole 148h functions as an example of the rotation center of the temple 180. Further, when viewed from the front-rear direction, a groove (hereinafter referred to as "concave groove") is formed in the central portion of the first hinge portion 148 in the vertical direction so that the first hinge portion 148 has a concave shape. Has been done.

The end portion (second hinge portion 230) of the temple 180 is inserted into the concave groove of the first hinge portion 148. The first hinge portion 148 supports the temple 180 by using both side surfaces 148a and 148b of the concave groove, and uses the bottom surface 148c of the concave groove (a surface substantially parallel to the back surface of the Yoroi 147). The rotation of the temple 180 is stopped by contacting the end of the temple 180. The hinge may be configured by forming the second hinge portion 230 in a concave shape and the first hinge portion 148 in a plate shape.

The temple 180 is an L-shaped member that is curved to fit the temporal region. Further, the temple 180 is rotatably connected in a range from the folding position where the angle between the temple 180 and the front 140 is the smallest to the opening position where the angle between the temple 180 and the front 140 is the largest.

In the following, the longitudinal direction of the L-shape in the temple 180 is simply referred to as the “longitudinal direction”, and the cross-sectional direction intersecting the longitudinal direction is simply referred to as the “cross-sectional direction”. Further, the position where the angle between the temple 180 and the front 140 is the smallest is defined as the "folding position", and the maximum position of the temple 180 in the rotatable range, that is, the position where the angle between the temple 180 and the front 140 is the largest in the rotatable range. Is the "opening position". Further, the angle between the temple 180 and the front 140 is defined as the "opening angle". Further, the side facing the center side in the left-right direction is referred to as "inside", and the opposite is referred to as "outside".

<Temple 180>
Subsequently, the configuration of the temple 180 will be described in detail with reference to FIGS. 3 to 5.
FIG. 3 is a diagram for explaining the overall configuration of the temple 180 to which the present embodiment is applied. 4A and 4B are views for explaining in detail the configuration of the temple 180 to which the present embodiment is applied, FIG. 4A is a side view of the temple 180, and FIG. 4B is a side view. It is a top view of the temple 180. Further, FIG. 5 is a diagram for explaining the configuration of the temple core material 200 to which the present embodiment is applied. In the following description, for convenience, the temple 180 will be described as being located at the open position.

The temple 180 to which the present embodiment is applied is screwed into the temple cover 190, the temple core material 200 partially inserted into the temple cover 190, and the temple cover 190 and the temple core material 200 from the cross-sectional direction. It is equipped with a screw 195.

The temple cover 190 is in contact with both sides of the user's face (head) and both ears, receives horizontal and vertical forces from the user, and is integrally connected to the received forces. It is transmitted to the core material 200. The temple core material 200 adjusts the relative postures of the front 140 and the temple 180, and functions as an example of the deformation mechanism. Further, the screw 195 integrally connects the temple core material 200 to the temple cover 190. The temple cover 190 and the screw 195 are not necessarily the configurations required for the glasses 100.

As shown in FIGS. 3 and 4A and 4B, the temple cover 190 has a tip portion 190a formed on the front side of the screw 195 and a rear side of the screw 195 with the screw 195 as a boundary. It has a rear end 190b formed on the side. Further, a first notch 191 and a second notch 192 are formed in the tip portion 190a, and a mounting hole 196 is formed in the rear end portion 190b.

The tip portion 190a has the effect of a decoration that hides a part of the temple core material 200 when the glasses 100 are worn. In the tip portion 190a, a part of the temple core material 200, specifically, a portion of the temple core material 200 on the front side of the screw 195 (the second hinge portion 230, the first deformed portion 210 and the second deformed portion 210, which will be described later). 2 The deformed portion 220) is not inserted. Therefore, the portion of the temple core material 200 on the front side of the screw 195 is formed to be deformable by swinging with respect to the tip portion 190a. In other words, the tip portion 190a does not have a function of holding the temple core material 200. On the other hand, when the glasses 100 are worn, the tip portion 190a has a function of hiding a part of the temple core material 200 from the outside to the inside in the left-right direction.

The first notch 191 is formed so as not to prevent the temple core material 200 described later from being deformed in the vertical direction. Further, the first notch 191 is a slope formed on the innermost front side of the tip portion 190a, as shown in FIGS. 3 and 4B. Due to this first notch 191, a part of the front side of the temple core material 200 (the first deformed part 210 described later) is not covered by the tip portion 190a, and as a result, a part of the front side of the temple core material 200. A range that can be deformed by swinging in the vertical direction is secured.

The second notch 192 is formed so as not to prevent the temple core material 200 described later from being deformed in the left-right direction. Due to the second notch 192, the cross-sectional shape of the tip portion 190a is formed in a concave shape. Due to this second notch 192, the other part on the front side of the temple core material 200 (the second deformed portion 220 described later) can swing with respect to the tip portion 190a (concave depth direction). That is, a range that can be deformed by swinging in the left-right direction of the other part on the front side of the temple core material 200 is secured.

The rear end portion 190b holds the temple core material 200. Further, the rear end portion 190b has a mounting hole 196 formed in the central portion and has a pipe shape. The other part of the temple core material 200, specifically, the part of the temple core material 200 on the rear side of the screw 195 (core 240 described later) is completely inserted into the mounting hole 196 of the rear end portion 190b. ing. Further, the portion (core 240) of the temple core material 200 on the rear side of the screw 195 is integrally fixed to the rear end portion 190b by the screw 195. Therefore, the rear end portion 190b can transmit the received force to the portion (core 240) on the rear side of the screw 195 in the temple core material 200. That is, the rear end portion 190b and the portion of the temple core material 200 on the rear side of the screw 195 move (swing) together.

<Temple core material 200>
Next, the temple core material 200 to which this embodiment is applied will be described.
In order to improve the fit of wearing the glasses 100, it is conceivable to adjust the posture of the glasses 100 in two directions: the vertical direction for adjusting the posture of the front 140 and the left-right direction for adjusting the posture of the temple 180. ..
However, in order to adjust in such two intersecting directions, for example, a dedicated deformation mechanism for adjusting the posture in the vertical direction and another dedicated deformation mechanism for adjusting the posture in the left-right direction are separated. If it is provided in, there arises a problem that the deformation mechanism becomes complicated.
Therefore, the temple core material 200, which functions as an example of the deformation mechanism to which the present embodiment is applied, is subject to the adjustment of the inclination angle of the front 140 in the vertical direction and the temple 180 in the horizontal direction by one component as described later. By configuring the opening angle so that it can be adjusted, it is possible to adjust in two directions with a simple structure.

First, the configuration of the temple core material 200 will be described in detail with reference to FIGS. 3 to 5. FIG. 5 is a diagram for explaining the configuration of the temple core material 200 to which the present embodiment is applied. In the following description, for convenience, unless otherwise specified, the temple core material 200 will be described as being located at the open position. Further, in the description of the relationship between the user's head when the glasses 100 are worn, the temple cover 190 and the temple core material 200 will be described as the temple 180 without being separated.

The temple core material 200 to which this embodiment is applied has a function as an example of a deformation mechanism, and is composed of, for example, one kind of high-strength metal, β titanium (beta titanium) or the like. Further, from the front to the rear in the front-rear direction, the temple core material 220 includes a second hinge portion 230, a first deformed portion 210, a second deformed portion 220, and a core 240 in this order.

The second hinge portion 230, the first deformed portion 210, the second deformed portion 220, and the core 240 are integrally formed. That is, the temple core material 200 is one component composed of four parts, a second hinge portion 230, a first deformed portion 210, a second deformed portion 220, and a core 240. In the present embodiment, the second hinge portion 230 is formed on the temple core material 200 (temple 180), but may be formed on the front 140 side together with the first hinge portion 148.

The second hinge portion 230 functions as an example of the connecting portion, and is a portion having a plate-like shape as shown in FIGS. 4 (a) and 4 (b), and the first hinge portion 148 is located in the central portion. A screw hole 230h is formed to connect with the screw hole 230h. The screw hole 230h functions as an example of the rotation center of the temple 180. Further, as shown in FIG. 4B, the second hinge portion 230 has a curved surface 231 formed on the inside (lower side of FIG. 4B) when viewed from above to below. It is provided with a plane 232 formed on the front side (right side of FIG. 4B).

The second hinge portion 230 is inserted between the first hinge portions 148 formed on the front 140, and both are connected by a screw (not shown) which is an example of the rotation center of the temple 180. Has been done. The second hinge portion 230 is not limited to the one using a screw, and may be one using, for example, a spring. By connecting the second hinge portion 230 and the first hinge portion 148, the temple 180 is configured to be rotatable in the range from the folded position to the open position.

Further, at each position before entering the opening position from the folding position, that is, at each position in the rotation range excluding the opening position, the curved surface 231 of the second hinge portion 230 is a concave character of the first hinge portion 148. It is formed so as to face the bottom surface 148c of the groove. On the other hand, in the open position, the flat surface 232 comes into contact with the bottom surface 148c. As described above, when the temple 180 continues to rotate, the plane 232 comes into contact with the bottom surface 148c of the first hinge portion 148, so that the rotation of the temple 180 is stopped. That is, the flat surface portion 232 determines the opening position (opening angle at the opening position) due to the rotation of the temple 180, and functions as the rotation brake of the temple 180.

The first deformed portion 210 is formed so as to extend rearward from the second hinge portion 230, and is a plate-shaped portion having a substantially triangular shape when viewed from above to below (hereinafter, "triangular plate portion"). ). The wide side of the triangular plate portion faces the second hinge portion 230, and the narrow side faces the second deformed portion 220. That is, the first deformed portion 210 smoothly connects the second hinge portion 230 on the front side and the second deformed portion 220 on the rear side.

Further, in the first deformed portion 210, the vertical direction is the plate thickness direction of the triangular plate portion. That is, in the first deformed portion 210, the thickness in the vertical direction is thin, and at least a part of the thickness in the left-right direction is formed to be thicker than the thickness in the vertical direction. As described above, the first deformed portion 210 is formed to be thin in thickness, and is easily deformed in the vertical direction. Further, the vertical deformation of the first deformation portion 210 is a plastic deformation. The details of this vertical plastic deformation will be described later.

The second deformed portion 220 is a portion (spring member) corresponding to a spring formed so as to extend rearward from the first deformed portion 210. Further, when viewed from above to below, the second deformed portion 220 is formed in a substantially Z shape, and is a spring portion 221 that is curved inward in the left-right direction from the front to the rear. , Has a plate-shaped fixing portion 222. The spring portion 221 is formed inside the fixed portion 222 in the left-right direction. Further, the spring portion 221 has a spring portion 221a on the front side and a spring portion 221b on the rear side.

Further, the second deformed portion 220 is formed so that the left-right direction is the plate thickness direction, that is, the thickness in the left-right direction is thin and the thickness in the up-down direction is thick. In the present embodiment, the plate thickness of the second deformed portion 220 is increased from the front to the rear.
The ratio of the vertical thickness to the horizontal thickness of the first deformed portion 210 and the second deformed portion 220 can be determined according to, for example, the material of the temple core material 200, and the thickness is from the front to the rear. May be changed, or the thickness may be uniform.

By increasing the thickness of the spring portion 221b and the fixing portion 222 in this way, the strength of the spring portion 221b deformed by the external force and the length of the screw portion of the screw hole 225 into which the screw 195 is screwed are sufficiently secured. be able to. Further, by making the thickness of the spring portion 221a thinner, the spring portion 221a is more easily deformed than the spring portion 221b. Then, the length of the spring portion 221a in the front-rear direction can be changed by the deformation of the spring portion 221a. As described above, the spring portion 221 of the second deforming portion 220 is easily deformed in the left-right direction. Further, the deformation of the second deformation portion 220 in the left-right direction is an elastic deformation. The details of this elastic deformation in the left-right direction will be described later.

The core 240 is formed so as to extend further rearward from the second deformed portion 220. The cross section of the core 240 is substantially square or circular. It is inserted into a mounting hole 196 formed in the rear end portion 190b of the temple cover 190, and is integrally fixed to the temple cover 190 by a screw 195.

<Adjustment by the first deformed portion 210 and the second deformed portion 220>
Subsequently, with reference to FIGS. 6 to 8, the adjustment by the first deformed portion 210 and the second deformed portion 220 of the temple core material 200 according to the present embodiment will be described in detail. In the following description, for convenience, it is assumed that the temple cover 190 is not attached. Further, in the description of the relationship between the user's head when the glasses 100 are worn, the temple cover 190 and the temple core material 200 will be described as the temple 180 without being separated. Further, for convenience, it is assumed that the modern 160 is not attached.

FIG. 6 is a diagram for explaining adjustment by the first deformation unit 210 to which the present embodiment is applied. Further, FIG. 7 is a diagram for explaining an example of adjustment by the second deformed portion 220 to which the present embodiment is applied, and FIG. 8 is a diagram based on the second deformed portion 220 to which the present embodiment is applied. It is a figure for demonstrating another example of adjustment.

The spectacles 100 are held in an appropriate position by adjusting the posture with respect to the face by the nose pad 144 (see FIG. 2) and the temple 180 (temple core material 200). Specifically, the nose pad 144 supports the front 140 by sandwiching the user's nose from both sides, and determines the relative positional relationship between the front 140 (lens 110) and the user's eyes (eyeballs). Then, the temple 180 presses the user's temporal region from above with a constant pressing force so as to appropriately maintain the relative positional relationship determined by the nose pad 144, and the user's head. From both sides in the width direction of the head. In this way, the vertical position and the horizontal position of the glasses 100 are determined with respect to the face and head of the user, and are held at appropriate positions.

Here, the "appropriate position" is a position where the front 140 (lens 110) is horizontal to both eyes when viewed from the front (front-back direction) of the face, and from the side surface (left-right direction) of the face. Looking at it, it means a position where the optical axis of the lens 110 is aligned with the line of sight of the user, that is, a position where the forward tilt angle is an appropriate angle. The optimum forward tilt angle differs depending on the lens. For example, it is 5 to 10 degrees for distance-use regular glasses and about 15 degrees for near-distance glasses.

However, the human face is not completely symmetrical. The shapes, positions, and the like of facial organs such as eyes and ears on the left and right sides of the face are different, and for example, there are usually cases where the heights of the left ear and the right ear are different. The height difference between the left ear and the right ear varies from person to person. Due to the height difference between both ears, the height difference between the left and right ends of the front 140 is generated. Therefore, the feeling of wearing may be deteriorated and the eyes may be burdened. In the following, the problem caused by the height difference between the left and right ends of the front 140 will be referred to as the "tilt angle problem".

Also, the positions of both ears vary from person to person. For example, it is common for both ears to be high or low with respect to the eyes. When the positions of both ears are high, the forward tilt angle becomes large. On the other hand, if the positions of both ears are low, the forward tilt angle will be tilted in the opposite direction. Therefore, the optical axis of the lens 110 may not be aligned with the line of sight of the user, the wearing feeling may be deteriorated, and the eyes may be burdened. In the following, the problem caused by the forward tilt angle of the front 140 is referred to as the "forward tilt angle problem", and the position causing the forward tilt angle problem is referred to as the "forward tilt angle change position".

Furthermore, there are usually cases where the shape and contour of the head differ depending on gender, system, skeleton, age, and the like. For example, the width size of the head varies from person to person. If the opening angle applied to the temple 180 is too large with respect to the size of the head, the position of the lens 110 may be displaced, or the lens 110 may be loosened when worn. On the other hand, if the opening angle applied to the temple 180 is too small with respect to the size of the head, the tension is applied to the temporal region, and the user feels pain. Therefore, the feeling of wearing may be deteriorated and the eyes may be burdened. In the following, the problem due to the width size of the head will be referred to as the "opening angle problem".

Therefore, when wearing the glasses 100, that is, at the opening position of the glasses 100, it is necessary to adjust the glasses 100 to the most appropriate posture according to the characteristics of each person's face and head.

<Adjustment by the first deformation part 210>
In the following, the adjustment by the first deformation unit 210 will be described in detail with reference to FIG. The first deformed portion 210 shown in FIG. 6 is configured to solve the “tilt angle problem” and the “forward tilt angle problem” caused by the positions of the ears (for example, the height with respect to the eyes, the height difference between the ears, etc.). Is.

Here, as described above, the nose pad 144 (see FIG. 2) determines the position of the front 140 with respect to the user's eyes. Therefore, the position of the first hinge portion 148 attached to the front 140 and the position of the second hinge portion 230 connected to the first hinge portion 148 are both determined by the nose pad 144. Therefore, the forward tilt angle in the front-rear direction and the tilt angle in the left-right direction of the lens 110 (front 140) change depending on the contact position between the temple 180 and the left and right ears of the user.
As described above, the first deforming portion 210 of the present embodiment deforms the temple 180 (temple core material 200) upward or downward by using a portion having a thin vertical thickness that is easily deformed by itself. The relative position of the temple 180 and the front 140 is adjusted to adjust the lens 110 (front 140) to the most appropriate position (posture) with respect to the user's eyes.

When dealing with the "tilt angle problem" by using such a first deformed portion 210, it is usually sufficient to deform the first deformed portion 210 of one temple and adjust so that the positions of the two temples are aligned. .. However, it is also possible to adjust the posture by deforming the first deformation portion 210 of each of the pair of temples 180.
On the other hand, when the first deformed portion 210 is used to deal with the "forward tilt angle problem", in principle, the first deformed portion 210 of each of the pair of temples 180 is deformed so that the front 140 has an appropriate forward tilt angle. Adjust to.

In the following, only the adjustment of one of the temples 180 will be described as a basic situation with reference to FIG. FIG. 6 is a diagram for exemplifying the positions A, B, and C of the ears and explaining that the first deformed portion 210 can appropriately adjust the positions of the ears.

The ear position A is a position where the posture of the lens 110 (front 140) is maintained at an “appropriate position” with respect to the eyes without adjusting the position of the temple 180 with respect to the eyes.

Specifically, when the glasses 100 are hung on the ears (not shown) at the position A, the temple 180 does not lift the left-right end (Yoroi 147) of the front 140 by contact with the ears. Therefore, the "tilt angle problem" does not occur. Further, since the ear position A is not the forward tilt angle change position, the "forward tilt angle problem" does not occur at this position.
Therefore, when the ear is in the position A, the wearing feeling of the user does not deteriorate, and it is not necessary to make adjustments for improving the wearing feeling.

On the other hand, the ear positions B and C are positions where the posture of the lens 110 (front 140) cannot be maintained at the "appropriate position" unless the position of the temple 180 is adjusted by the first deformed portion 210.

Specifically, when the glasses 100 are hung on the ear at the position B (not shown) when the adjustment is not performed by the first deformed portion 210, the temple 180 comes into contact with the ear at the high position, and the temple The posture of the 180 and the front 140 changes, and the "tilt angle problem" and the "forward tilt angle problem" occur. Therefore, when the ear is in the position B, the wearing feeling of the user deteriorates, and it is necessary to make adjustments for improving the wearing feeling.

Further, when the glasses 100 are hung on the ear at the position C (not shown) when the adjustment is not performed by the first deformed portion 210, the temple 180 comes into contact with the ear at the lower position, and the temple 180 or the front The posture of 140 changes, and the "tilt angle problem" and the "forward tilt angle problem" also occur. Therefore, when the ear is in the position C, the wearing feeling of the user deteriorates, and it is necessary to make adjustments for improving the wearing feeling.

In the present embodiment, the postures of the lens 110 (front 140) and the temple 180 are adjusted by using the first deformed portion 210.
Specifically, when adjusting the position B of the ear, an external force is applied to deform the portion on the rear side of the first deforming portion 210 upward in the vertical direction. As a result, the first deformed portion 210 supports the posture of the lens 110 (front 140) in the "appropriate position" by the portion on the front side of the first deformed portion 210, and the temple is supported by the portion on the rear side. The 180 can be tilted upwards to allow proper contact with ear position B.

Further, when adjusting the position C of the ear, an external force is applied to deform the portion on the rear side of the first deforming portion 210 downward in the vertical direction. As a result, the first deformed portion 210 supports the posture of the lens 110 (front 140) in the "appropriate position" by the portion on the front side of the first deformed portion 210, and the temple is supported by the portion on the rear side. The 180 can be tilted downwards to allow proper contact with ear position C.

In this way, the posture-adjusted temple 180 maintains the posture of the lens 110 (front 140) in the "appropriate position" with respect to the eyes even when the glasses 100 are hung on the ears at the positions B and C. It is supposed to be done. That is, the "tilt angle problem" and the "forward tilt angle problem" can be solved.

When adjustment by the first deformed portion is required, such as the above-mentioned ear positions B and C, the first deformed portion 210 is plastically deformed, so that the temple 180 can maintain its deformed shape. can. Therefore, it is not necessary to make adjustments in the vertical direction each time the glasses 100 are worn, and the wearability is improved.
Further, in the present embodiment, since the first deformed portion 210 is arranged on the front 140 side, the first deformed portion 210 is arranged on the modern 160 (see FIG. 1) side as compared with the case where the first deformed portion 210 is arranged on the front 140 side. Due to the small deformation of the deformed portion 210, the side of the temple 180 that hangs on the ear can be greatly moved. Therefore, it is possible to flexibly respond to ears at various positions, and it is possible to adjust in a wide range.

<Adjustment by the second deformation part 220>
In the following, the adjustment by the second deformation portion 220 will be described in detail with reference to FIGS. 7 and 8. The second deformed portion 220 shown in FIGS. 7 and 8 is configured to solve the “opening angle problem”.
Further, FIGS. 7 and 8 exemplify the width sizes W1 and W3 of the head, and the second deforming portion 220 elastically deforms according to various head width sizes to wear the glasses 100 on the user's head. It is a figure for demonstrating that it fits a part.

In the case of FIG. 7, the second deforming portion 220 makes a small elastic deformation according to the head of a user having a small head width size W1 and fits the glasses 100 to the head of this user.
On the other hand, in the case of FIG. 8, the second deformed portion 220 undergoes a large elastic deformation according to the head of a user having a head width dimension W3 larger than the small head width size W1, and the glasses 100 are used. Fit to the person's head.

The elastic deformation of the second deformed portion makes it possible to fit the glasses 100 according to the head width size of various people. Further, the adjustment by the elastic deformation is adjusted to the optimum posture according to the size of the head each time the glasses 100 are worn, so that the wearability is improved.
