Utility Model Registration No. 3214012

In the above-mentioned conventional earrings, a pierced earring fixing portion, which is a member different from the main body, is attached to the outside of the ring-shaped main body.
With such earrings, when the body with the pierced earrings fixed is attached to the ear, the ornament will appear to hang away from the ear.
While pierced earrings have ornaments directly attached to the ears, conventional earrings with ornaments hanging below the ears have a less pierced feel. In other words, conventional earrings could not give the same fashionable feeling as earrings.
An object of the present invention is to provide an earring that allows a person who has not opened a pierced hole to enjoy the same fashionable feeling as a pierced earring.

In the first invention, an ear cuff body for sandwiching ears with a pair of sandwiching portions is provided, and an insertion hole forming portion is formed at the bottom of the ear cuff body facing the facing distance between the pair of sandwiching portions, and the insertion hole forming portion is formed. Is formed with an insertion hole that is sandwiched between the sandwiched portions and penetrates in the thickness direction of the ear. The insertion hole maintains a shape and dimension in which all or part of the inner peripheral surface of the insertion hole can be brought into close contact with the inserted piercing post, and the insertion hole and the piercing post inserted into the insertion hole. The frictional force of the part in close contact with the pierced post exerts the function of preventing the pierced post from coming off.
The bottom of the ear cuff body facing the pinching portion is a portion facing the thick portion of the ear when the ear is pinched by the pinching portion.

In the second invention, at least the insertion hole forming portion is made of a material that can be elastically deformed, and the insertion hole is formed in the insertion hole forming portion.
The elastically deformable material that constitutes the insertion hole forming portion is that the insertion hole having an inner diameter smaller than the outer diameter of the piercing post is deformed in the diameter-expanding direction in the process of pushing the piercing post, and the piercing post penetrates. It is a material that adheres tightly and exerts elastic force in the tightening direction, such as rubber.

In the third invention, the insertion hole formed in the insertion hole forming portion made of an elastically deformable material is curved in an arc shape, and a straight line passing through both ends of the concave arc in the insertion hole and a convex The distance from the tangent line passing through the center of the side arc is less than the outer diameter of the piercing post.
Then, in the process of pushing the piercing post through the opening of the insertion hole, the tip of the piercing post is pressed against the convex arc portion, and the convex arc portion is crushed as the piercing post advances in the pushing direction. While elastically deforming, reaction force due to elastic deformation of the convex arc portion acts on both ends of the concave arc via the piercing post, and both ends expand in the axial direction of the piercing post. It deforms elastically while being pierced.
When the piercing post penetrates the insertion hole, a part or the entire surface of the inner peripheral surface of the insertion hole is brought into close contact with the outer periphery of the piercing post so that the frictional force is exerted on the piercing post. There is.

In the fourth invention, at least the insertion hole forming portion is made of metal, the insertion hole is curved in an arc shape, and a straight line passing through both ends of the concave arc in the insertion hole and a convex arc. The distance from the tangent line passing through the central portion is maintained so that the piercing post can be pushed in, and both ends of the concave arc and the central portion of the convex arc are in close contact with the piercing post penetrating the insertion hole. The frictional force is exerted.

In the fifth invention, the insertion hole having a flat cross-sectional shape on a plane orthogonal to the insertion direction of the piercing post is formed in the insertion hole forming portion, and the cross-sectional shape of the insertion hole is pierced on the minor axis in its natural state. While being kept below the outer diameter of the post, the cross section expands in the minor axis direction due to the pinching force from both ends in the long axis direction, and when the pinching force is released, the insertion hole changes from the enlarged state to the flat state. All or part of the inner peripheral surface of the insertion hole is in close contact with the pierce post inserted into the insertion hole, and the frictional force is exerted.

In the sixth invention, the ear cuff body is made of a plastically deformable material, and the facing distance between the pair of sandwiching portions can be adjusted within a range smaller than the thickness dimension of the ears sandwiched between these sandwiching portions. There is.
By using the above-mentioned plastically deformable material, it is possible to maintain the facing distance between the adjusted pair of holding portions. However, the adjustable range is a small range of several millimeters or less.

In the present invention, the insertion hole forming portion is formed at the bottom of the ear cuff body, and the insertion hole and the ear cuff body are integrated.
Therefore, if the bottom portion on which the insertion hole is formed is attached close to the contour of the ear, the insertion hole can be located near the contour of the ear, and the pierced ornament fixed to the insertion hole and the ear You can create a sense of unity.
Therefore, even a person who has not opened the pierced hole can enjoy the pierced feeling as if the ornament was directly attached to the ear.
In addition, the frictional force between the inner peripheral surface of the insertion hole and the pierced post prevents the pierced post from coming off, so there is no need to attach a pierced catch to the back of the ear. No piercing catch is required, so you won't lose your piercing catch or your hair will get caught in the piercing catch.

In the second invention, by forming the insertion hole in the elastically deformable material, the piercing post pushed into the insertion hole exerts a strong frictional force based on the elastic force, and the piercing post is more reliably prevented from coming off. can do.

In the third invention, the curved insertion hole is elastically deformed by the insertion of the piercing post, and the frictional force can be exerted by the elastic force acting on the piercing post. In particular, since the amount of deformation is large at the central portion of the convex arc portion and both ends of the concave arc portion, the frictional force corresponding to the elastic force is concentrated, and the removal prevention function can be enhanced.

In the fourth invention, a pierced post that matches the distance between the straight line passing through both ends of the concave arc and the tangent of the central portion of the convex arc is passed through, and the central portion of the convex arc and the concave arc portion are formed on the outer circumference thereof. It is possible to exert a frictional force against pulling out by bringing the three points into close contact with both ends of the.
It is difficult to push the piercing post into a linear insertion hole that is formed of a metal that does not elastically deform and matches the outer diameter of the piercing post, but in the present invention, it is possible to prevent the piercing post from coming off that matches the distance between the straight line and the tangent line. It is possible.
That is, according to the present invention, the piercing post can be inserted from an inlet larger than its outer diameter, so that it is easy to insert and it is possible to prevent it from coming off.

Also, since the piercing post has a small diameter, it easily bends due to the action of external force. When the piercing post hits the inner peripheral surface of the insertion hole in the process of passing through the insertion hole, it can be easily penetrated through the slightly bent and curved insertion hole along the contact surface. Then, the pierced post that is slightly bent during the insertion process returns to a straight line after penetrating, and the outer circumference of the pierced post comes into close contact with the above three points of the insertion hole due to its elastic force, and the frictional force exerts the removal prevention function. be able to.

In the fifth invention, when the piercing post is inserted, the cross-sectional shape of the flat insertion hole is deformed and the dimension in the minor axis direction smaller than the outer diameter of the piercing post is increased, so that the inner peripheral surface of the insertion hole and the piercing post are increased. It is possible to eliminate the influence of the frictional force with the outer circumference of the. In this way, the pierced post can be easily inserted, and the elastic force of the insertion hole, which has returned to a flat shape after penetration, exerts a frictional force to exert a pull-out prevention function.

According to the sixth invention, the facing distance between the pair of holding portions can be adjusted according to the thickness of the ear within the range in which plastic deformation is possible.
Even if the distance between the holding parts is the same, if the ear thickness is small, the holding force will be weak and the ear cuff body will easily fall off, and if the ear thickness is large, the holding force will be too strong and pain will occur during wearing. You may feel. In the present invention, since the facing distance between the holding portions can be adjusted according to the thickness of the ear, it is possible to prevent the ear cuff body from falling off without feeling pain during wearing.

It is a perspective view of the ear cuff main body of 1st Embodiment. FIG. 2 is a sectional view taken along line II-II of FIG. 1, showing a state in which the piercing post is not inserted. The second embodiment is shown, and is a partial view in the same cross section of FIG. It shows the 3rd Embodiment and is the same partial cross-sectional view as FIG. It is a partial cross-sectional view which showed the state which made the pierced post penetrate through the insertion hole of FIG. It shows the 4th Embodiment and is the same partial cross-sectional view as FIG. It is a partial cross-sectional view which showed the state which made the pierced post penetrate through the insertion hole of FIG. It is a partial cross-sectional view which showed the state which made the piercing post thinner than the piercing post of FIG. 7 penetrate through the insertion hole of FIG. FIG. 5 is a partial cross-sectional view of the fifth embodiment, which is a cross-sectional view in a direction orthogonal to the insertion direction of the piercing post. It is a partial cross-sectional view of the state where the insertion hole of FIG. 9 is compressed from both ends in the long axis direction. It is a partial cross-sectional view of the state where the piercing post is inserted into the insertion hole of FIG.

The earrings of the first embodiment shown in FIGS. 1 and 2 include a metal ear cuff body 1. The ear cuff body 1 is provided with a pair of holding

portions

2 and 3 facing each other at a predetermined interval, and an earlobe or the like is sandwiched in the interval S.
Then, recesses 2b and 3b surrounded by annular

convex portions

2a and 3a are formed on the surfaces of the sandwiching

portions

2 and 3 facing each other, and when the ear cuff body 1 is attached, the flesh of the ear becomes the

recesses

2b and 3b. It overhangs inside to prevent the ear cuff body 1 from falling off.

Further, a linear through hole 5 extending in the width direction (arrow W direction) is formed in the bottom portion 4 facing the holding

portions

2 and 3. A rod-shaped silicone rubber member 6 forming an insertion hole forming portion is embedded in the through hole 5, and a linear insertion hole 6a for inserting the pierce post A is formed in the center thereof. The inner diameter of the linear insertion hole 6a is smaller than the outer diameter of the piercing post A. In this embodiment, the silicone rubber is the elastically deformable material of the present invention, but the elastically deformable material also includes natural rubber and synthetic rubber other than silicone rubber.

Then, when a pierce post A (not shown) provided with a decorative body for earrings is pushed into the insertion hole 6a, the insertion hole 6a is elastically deformed in the diameter expansion direction, and the elastic force acts on the pierce post A.
In this first embodiment, since the piercing post A larger than the inner diameter of the insertion hole 6a is pushed into the linear insertion hole 6a, the outer peripheral surface of the penetrating piercing post A is the inner peripheral surface of the insertion hole 6a. Almost all of them are in close contact with each other, and a frictional force is generated at the close contact portion, so that the removal prevention function of the present invention is exhibited.

The dimensional relationship of the present invention in the linear insertion hole 6a is that the piercing post A can be pushed into the insertion hole 6a with a finger and can be pulled out by pinching it with a finger. It means a dimensional relationship in which the pierced post does not come off under the action of gravity.
The dimensional relationship also changes depending on the characteristics of the material such as the elastic modulus and friction coefficient of the elastically deformable member.

As long as the above dimensional relationship is maintained, the piercing post A will not accidentally come out of the insertion hole 6a. Therefore, it is not necessary to catch the pierced earring to prevent the pierced post A from coming off.

Further, in the earring of the first embodiment, since the insertion hole 6a is integrally provided in the ear cuff main body 1, the decorative body attached to the insertion hole 6a is integrated with the ear cuff main body 1. When such an ear cuff body 1 is attached to the ear, it is possible to create a sense of unity between the decorative body and the ear, and even a person who has not opened the pierced hole feels as if the decorative body is directly attached to the ear. You can enjoy it.

In the second embodiment shown in FIG. 3, the structure of the insertion hole is different from that in the first embodiment, but the overall shape of the metal ear cuff body 1 is the same as that in the first embodiment. In this second embodiment, the same components as those in the first embodiment are designated by the same reference numerals as those in FIG. 1, and FIG. 1 is referred to.
In the second embodiment, a through hole 7 extending in the width direction is formed in the bottom portion 4 of the ear cuff main body 1. A large diameter portion 7a is provided in the center of the through hole 7, and the inner diameters of the

small diameter portions

7b and 7c are larger than the outer diameter of the pierce post A on both sides thereof.

An insertion hole forming portion made of an elastically deformable silicone rubber member 8 is provided in the large diameter portion 7a, and a linear insertion hole 8a is formed in the center of the silicone rubber member 8.
The dimensional relationship in which the inner peripheral surface of the insertion hole 8a is in close contact with the outer peripheral surface of the piercing post A is the same as that of the insertion hole 6a of the first embodiment.
Therefore, also in this second embodiment, the frictional force acts on the pierced post A penetrating the insertion hole 8a to exert the function of preventing the pierced post A from coming off, and the decorative body does not fall off even without the pierced catch.
Further, also in this second embodiment, since the insertion hole 8a is formed in the bottom 4 of the ear cuff main body 1, it is possible to give a pierced feeling with a sense of unity between the decorative body and the ear as in the first embodiment. it can.

However, in this second embodiment, both ends of the insertion hole 8a are communicated with the

small diameter portions

7b and 7c via the

funnel portions

8b and 8c, so that the small diameter portion 7b and the funnel portion 8b on the insertion port side of the piercing post are connected. The tip of the piercing post functions as a guide hole leading to the insertion hole 8a, making it easier to insert the piercing post A into the insertion hole 8a.
In the second embodiment, the insertion hole forming portion made of the silicone rubber member 8 is provided in the center of the through hole 7, but where is the insertion hole 8a that exerts the frictional force provided in the bottom portion 4 of the ear cuff main body 1. It is free.

The ear cuff body 1 in the third embodiment shown in FIGS. 4 and 5 has the same shape as the first embodiment shown in FIG. An insertion hole 9 having a circular opening and curved in an arc shape along the insertion direction of the pierce post A is formed in the bottom portion 4 of the metal ear cuff main body 1.
4 and 5 are cross sections that pass through the diameter of the cross-sectional circle of the insertion hole 9, and show the same surface as that of FIG.
Then, in the third embodiment, the bottom portion 4 of the ear cuff main body 1 constitutes a metal insertion hole forming portion.
In FIGS. 4 and 5, the size and curvature of the insertion hole 9 are shown larger than they actually are for the sake of explanation.

As shown in FIG. 4, in the insertion hole 9, a concave arc 10 whose inner peripheral surface of the hole is recessed toward the outside and a convex arc 11 protruding inward facing the concave arc 10 are formed. appear. These arcs 10 and 11 are concentric arcs along the insertion direction of the pierce post A, and the opposite distance D1 between the two

arcs

10 and 11 is kept constant.

Further, the straight line passing through both ends P1 and P2 of the concave arc 10 is L1, the tangent line passing through the central portion P3 of the convex arc 11 is L2, and the opposite distance D2 between the straight line L1 and the tangent line L2 is the insertion hole 9. It is set to be the same as or slightly smaller than the outer diameter d of the piercing post A inserted in. In other words, a pierce post A having an outer diameter d having the same diameter as or slightly larger than the interval D2 is inserted into the insertion hole 9.
Inserting the pierced post A having an outer diameter d equal to or slightly larger than the interval D2 into the insertion hole 9 as described above means that the outer circumference of the pierced post A inserted in the interval D2 becomes the straight lines L1 and L2. Will come into contact.

As a result, as shown in FIG. 5, both ends P1 and P2 of the concave arc 10 and the central portion P3 of the convex arc 11 serve as close contact portions on the outer peripheral surface of the piercing post A penetrating the insertion hole 9. Pressing pressures F1, F2 and F3 are applied to the post A. The pressing forces F1, F2, and F3 exert a frictional force to prevent the pierced post A from coming off.

When the interval D2 of the straight lines L1 and L2 is larger than the outer diameter d of the pierced post A, the both end portions P1, P2 and the central portion P3 do not come into close contact with the outer circumference of the pierced post A inserted at this interval. It will be.
On the other hand, if the interval D2 is too small compared to the outer diameter d, the pierce post A cannot be pushed by a person by hand.
Therefore, the shape and dimensional relationship that enables the inner peripheral surface of the insertion hole 9 and the outer periphery of the piercing post A of the third embodiment to be brought into close contact with each other are such that the distance D2 is equal to or less than the outer diameter d and the piercing post A is pointed to. It is a size that can be inserted and removed with.

Further, since the outer diameter d of the pierce post A is about 1 [mm] at the maximum, when it collides with the inner peripheral surface of the insertion hole 9 in the process of passing through the insertion hole 9, the concave or convex arc 10, It can bend along 11 and return to a straight line after penetrating. In this way, if the pierced post A is bent even slightly during the insertion process, the pierced post A can easily penetrate through the curved insertion hole 9.
On the other hand, when the outer diameter d is slightly larger than the interval D2, the pierced post A penetrating the insertion hole 9 is maintained in a state of being slightly curved in the same direction as the arc, but at that time, the pierced post is maintained. The elastic force that returns A to the linear state acts from the pierced post A to the contact portions P1, P2, and P3 to exert a frictional force.

In this way, even if the periphery of the insertion hole 9 is made of a metal that is not easily elastically deformed, the pierce post A having an outer diameter d that is the same as or slightly larger than the interval D2 is inserted into the curved insertion hole 9 and is removed. The prevention function can be exerted.
Further, in the third embodiment, since the insertion hole forming portion is integrated with the metal ear cuff main body, the metal ear cuff main body 1 is partially covered with silicone rubber or the like as in the first and second embodiments. It is not necessary to provide a separate member, and a simpler configuration can be realized.

In the third embodiment, the guidance for facilitating the insertion of the pierce post A into the opening of the insertion hole 9 on the one end P1 side of the concave arc 10 which is the entrance when the pierce post A is press-fitted. The holes may be continuous. If the guide hole has a funnel shape whose diameter expands toward the opening side, the pierce post A can be easily guided toward the insertion hole 9.
In this case, the end P1 of the concave arc 10 in the present invention appears at the boundary between the guide hole and the insertion hole 9.

Also in the third embodiment as described above, since the insertion hole is formed in the bottom 4 of the ear cuff main body 1, the piercing feeling with a sense of unity between the decorative body and the ear is obtained as in the first embodiment. Can be done.

The fourth embodiment shown in FIGS. 6 to 8 includes an ear cuff body 12 made of silicone rubber, which is an elastically deformable material. The ear cuff main body 12 has the same appearance as the ear cuff main body 1 of the first embodiment shown in FIG. An insertion hole 14 is formed in the bottom portion 13 which is a portion facing the pair of holding portions (not shown). In the fourth embodiment, the bottom portion 13 of the ear cuff body 12 is an insertion hole forming portion made of an elastically deformable material.

Further, the insertion hole 14 is curved in an arc shape like the insertion hole 9 of the third embodiment, and the concave arc 15 and the convex arc 16 are concentric arcs, and the opposite distance D3 is kept constant. There is. This interval D3 is made substantially equal to the outer diameter d of the pierce post A.
Therefore, the distance D4 between the straight line L1 passing through both end portions P1 and P2 of the concave arc 15 and the tangent line L2 of the central portion P3 of the convex arc 16 is naturally smaller than the outer diameter d.
In other words, a pierce post A having an outer diameter d larger than the interval D4 of the straight lines L1 and L2 is inserted.

When such a pierced post A is pushed in from the entrance side of the insertion hole 14, its tip abuts on the convex arc 16. If the pierce post A that abuts on the convex arc 16 is pushed in as it is, the convex arc portion is elastically deformed while being crushed as the pierce post advances in the pushing direction.
On the other hand, reaction forces due to elastic deformation of the convex arc portion act on both ends P1 and P2 of the concave arc 15 via the pierce post A, and the both ends P1 and P2 are the axes of the pierce post A. It deforms elastically while being pushed out in the direction.

If the pierce post A is penetrated while elastically deforming the concave arc 15 and the convex arc 16 as described above, the curved insertion hole 14 is on a straight line along the penetrating pierce post A as shown in FIG. The elastic force F acts from the concave arc 15 and the convex arc 16 toward the pierce post A. The elastic force F has a size corresponding to the amount of deformation of the silicone rubber around the insertion hole 14. Therefore, the force acting on the pierce post A is greatest at both ends P1 and P2 of the concave arc 15 and at the center P3 of the convex arc 16. That is, elastic forces in opposite directions are concentrated at both end portions P1 and P2 and the central portion P3. Due to this concentrated force, a large frictional force is generated in those close contact parts, and the pull-out prevention function is exerted.

As described above, when the outer diameter d of the pierced post A is equivalent to the interval D3 of the arc, almost the entire inner peripheral surface of the insertion hole 14 is in close contact with the outer peripheral surface of the penetrating pierced post A. .. The same applies when the outer diameter d is larger than the interval D3. The larger the outer diameter d, the larger the amount of deformation around the insertion hole 14, so that the elastic force acting on the outer peripheral surface of the pierce post A becomes larger, and the frictional force due to this becomes larger.

On the other hand, in the fourth embodiment, when the pierce post A having an outer diameter d'smaller than the facing distance D3 of the arc is inserted, it is the same as when the pierce post A having the same outer diameter d as the distance D3 is inserted. In comparison, the amount of deformation of the convex arc 16 and the concave arc 15 is smaller. Therefore, as shown in FIG. 8, a gap is formed between the

arcs

15 and 16 and the outer peripheral surface of the pierce post A.
In this way, the entire inner peripheral surface of the insertion hole 14 does not come into close contact with the outer periphery of the pierced post A, but a part of the inner peripheral surface comes into close contact, and an elastic force acts on the pierced post A at this contacted portion to cause friction. A force can be generated to exert the pull-out prevention function.

When the outer diameter d of the pierce post A is smaller than the distance D4 of the straight lines L1 and L2, the inner peripheral surface of the insertion hole 14 does not come into close contact with the outer circumference of the pierce post A penetrating the insertion hole 14, so that the insertion hole 14 is prevented from coming off. It cannot function. Therefore, it is essential that the distance D4 between the straight lines L1 and L2 is smaller than the outer diameter d of the pierce post A. However, this interval D4 needs to have a size that allows the pierce post A to be pinched and pushed in at a minimum.

Also in the fourth embodiment as described above, since the insertion hole 14 is formed in the bottom 13 of the ear cuff main body 12, the piercing feeling with a sense of unity between the decorative body and the ear is obtained as in the first embodiment. Can be done.
In this fourth embodiment, the ear cuff body 12 is made of silicone rubber, but only the insertion hole forming portion in which the ear cuff body is made of metal to form the insertion hole 14 is made of an elastically deformable material such as silicone rubber. You may.
Further, for example, a funnel-shaped guide hole may be continuously connected to one end P1 of the concave arc 15 which is the entrance side of the insertion hole 14.

Further, the curved insertion holes 9 and 14 of the third and fourth embodiments are curves in which the ear side on which the

ear cuff bodies

1 and 12 are attached is a convex side, but the bending direction of the insertion holes is not limited to this. As long as the through holes are formed in the width directions of the

bottoms

4 and 13, the insertion holes 9 and 14 may be curved in any direction.
Further, in the third and fourth embodiments, the convex arc and the concave arc are formed by concentric arcs having a constant facing distance, but both arcs are not limited to concentric arcs, and each arc is partially. It may be an arc whose curvature changes.

The fifth embodiment shown in FIGS. 9 to 11 includes an ear cuff body 12 made of silicone rubber similar to that of the fourth embodiment, and has an insertion hole 17 having a slit-shaped cross section penetrated linearly through the bottom portion 13. is there. FIG. 9 is a cross-sectional view orthogonal to the insertion direction of the pierce post A (see FIG. 11).
The insertion hole 17 of the fifth embodiment is a flat opening having a long axis a and a short axis b in the cross section of the bottom portion 13 as shown in FIG. 9 in a natural state. The flat opening is not limited to a slit shape, but may be an ellipse or a rectangle. Then, the short axis b in the natural state is made smaller than the outer diameter d of the pierce post A. Further, the long axis a is larger than the outer diameter d in the natural state, and is made larger than the diameter d of the pierce post A even when the holding forces f and f are applied from both ends thereof, as will be described later. ..

When inserting the pierced post A into the flat insertion hole 17 as described above, the holding forces f and f are applied from both ends of the long axis a by pinching the insertion hole 17 from the outside of the bottom portion 13, and FIG. As described above, the short axis b is enlarged beyond the outer diameter d of the pierce post A. When the short axis b is enlarged in this way, the opening of the insertion hole 17 becomes larger than the cross section of the pierce post A. Therefore, the piercing post A can be easily penetrated through the insertion hole 17. After penetrating the pierce post A, if the pinching hand is released and the holding forces f and f are released, the insertion hole 17 returns to the flat state, and as shown in FIG. 11, both ends of the short axis b are the pierce post A. Adhere to.

In the fifth embodiment, as shown in FIG. 11, the inner peripheral surfaces on both ends of the short shaft b are in close contact with the outer circumference of the pierce post A to exert an elastic force, and the frictional force due to this elastic force is the pierce post A. Demonstrates the function of preventing piercing.
The dimensional relationship that the inner peripheral surface of the flat insertion hole 17 of the fifth embodiment can be brought into close contact with the outer circumference of the piercing post A is smaller than the outer diameter of the piercing post A in the natural state of the short axis b of the insertion hole 17. The opening deformed by applying the holding forces f and f from both ends of the long axis a is large enough to insert the pierced post A.
However, the position and size of the close contact portion can be changed depending on the elasticity of the material constituting the bottom portion 13 and the opening shape of the insertion hole 17.

The fifth embodiment is the same as the first embodiment in that the frictional force can be exerted by the elastic deformation around the insertion hole 17. However, this fifth embodiment has a feature that the short axis b can be enlarged to facilitate insertion of the pierce post A. When the pierced post A is pulled out, the short axis b can be enlarged and easily pulled out as in the case of insertion.
In this fifth embodiment as well, since the insertion hole 17 is formed in the bottom 13 of the ear cuff main body 12, it is possible to give a pierced feeling with a sense of unity between the decorative body and the ear as in the other embodiments described above.

Also in this fifth embodiment, a funnel-shaped guide hole or the like that expands in diameter toward the entrance may be provided at the end of the insertion hole 17 on the entrance side.
Further, only the bottom portion 13 which is the insertion hole forming portion for forming the flat insertion hole 17 may be made of an elastically deformable material such as silicone rubber, and the other portion may be made of metal.

As described above, the earrings of the first to fifth embodiments can fix the decorative body only by inserting the piercing post into the insertion hole formed in the ear cuff body, and even a person who does not have a piercing hole in the ear feels pierced. You can enjoy it.
Then, if the overall shape of the ear cuff body and the facing distance between the pair of holding portions are set according to each portion of the ear, the ear cuff can be attached to various positions of the ear other than the earlobe.
Further, if the ear cuff body is made of a plastically deformable metal or the like, the facing distance S (see FIG. 2) of the pair of holding portions can be finely adjusted according to the thickness of the wearer's ear.

Further, if the inner peripheral surface of the insertion hole is provided with irregularities, the pressing force on the pierce post A can be concentrated on the convex portion and the frictional force can be concentrated.
Further, the friction coefficient can be controlled by the material and roughness of the inner peripheral surface of the insertion hole, and the frictional force at the portion in close contact with the outer periphery of the pierce post A can be adjusted.

Further, if the ear cuff body is made of a transparent resin or the like, the ear cuff body can be made inconspicuous, and the piercing feeling can be further enhanced.
Further, if the ear cuff body is attached with a decorative body different from the pierced earring decoration body, or if the ear cuff body is decorated with a sculpture or the like, the decorative effect can be further enhanced.

People who do not have pierced holes in their ears can also enjoy the feeling of piercing.
