Conventionally, a fastener 100 shown in FIG. 8 is widely known as a fastener for accessories. The fastener 100 includes a connection plate 110 that is a member to be connected on the side to be connected, and a pull ring 120 that is a connection member on the side to be connected. The connection plate 110 is a substantially oblong flat plate, and has two through holes at both ends in the longitudinal direction. The through hole on the rear end side is a mounting hole 111 for attaching a chain member (linear member), and the through hole on the front end side is a connecting hole 113 for connecting the pull ring 120 in a separable (disconnectable) manner. is. The pull ring 120 is a substantially annular member comprising an openable/closable opening/closing member 121 having an opening lever 122 that is biased into a closed state by biasing means (not shown), and a main body portion 123 . The inner space of the annular member serves as a holding space 125 for holding the tip side of the connecting plate 110 , and the opening/closing member 121 can open and close the holding space 125 .

An example of wearing an accessory (such as a necklace) having this fastener 100 will be described. The user holds the connection plate 110 and the pull ring 120 in both hands, respectively, and connects them as follows.

First, one hand holds the rear end side of the connecting plate 110 so that the connecting hole 113 is not hidden. At this time, the longitudinal direction of the connecting plate 110 is oriented so as to substantially match the directions of the fingertips of the thumb and forefinger so that the position of the connecting hole 113 can be estimated even if it cannot be visually recognized. Also, with the other hand, the opening lever 122 is operated with a fingertip or a nail to open it, and an insertion opening 127 that is a gap connecting to the holding space 125 is made in the pull ring 120 . At this time, the insertion port 127 is positioned on the tip side of the fingertip so as to facilitate the connecting operation.

The user brings the fingertip connection plate 110 and the pull ring 120 to the back of the neck while maintaining the above-described state. Then, the distal end portion of the connecting plate 110 and the pull ring 120 are brought close to each other, and the position of the insertion opening 127 of the pull ring 120 is found from the state of contact between the members (that is, the position is aligned). The tip portion is inserted into the holding space 125 and passed through the connecting hole 113 through the open end of the main body portion 123 . When both fastening members 110 and 120 are slightly pulled and the latching is confirmed, the opening lever 122 is returned to the original position to close the insertion opening 127 and the holding space 125 is closed. In this way, the connecting plate 110 is connected to the pull ring 120 by hooking the connecting hole 113 to the opening/closing member 121 .

Here, the connecting operation of both fastening members 110 and 120 is an operation performed on the back side of the neck and cannot be visually recognized by the user. As described above, since the position of the insertion opening 127 is searched while finely adjusting the positions of the fastening members 110 and 120 only by the sense of the fingertips, the alignment operation is not easy. Moreover, both the fastening members 110 and 120 are members smaller than the tip of a finger. Even if both the fingertip fastening members 110 and 120 are held in a state suitable for connecting operation at first, the fastening members 110 and 120 may collide with each other or the fingertips when aligning the position on the back side of the neck. As a result, the holding position may shift. In particular, the plate-shaped connecting plate 110 is easy to slide on the fingertip, and the direction of the connecting hole 113 may change or the connecting hole 113 may be hidden by the fingertip.

When wearing the accessory along the neck, because the length of the accessory is short, bring both hands to the back of the neck (for example, around the 7th cervical vertebra) and perform the above connection operation. There is When both hands are brought to this position, both forearms and both hands are in a V-shaped posture, and the fingertips of both hands holding the both fastening members 110 and 120 face obliquely downward in a natural posture. . In this posture, the index fingers of both hands are in the way, and the connection operation cannot be performed well. In addition, in order to smoothly insert the distal end side of the pulling ring 120 into the insertion opening 127 of the pulling ring 120, the insertion opening 127 and the distal end side of the connection plate 110 are opposed to each other, and the opening direction of the insertion opening 127 (both open ends 127a) , 127b) and the thickness direction of the connecting plate 110 are generally parallel to each other. Both arms and both hands are twisted outward in order to set both fastening members 110 and 120 in this positional relationship. It is a burden for the user to maintain a twisted posture at a position close to the user's back.

Patent Literatures 1 to 3 disclose a connecting member having a different shape from the connecting plate 110, which is a conventional connecting member. However, there is no change in the shape of the flat plate, and like the connection plate 110, which is the member to be connected and fastened, the connection operation cannot be easily performed. In addition, when the surface of the member is roughened or a part of the member is made into a blade shape as in Patent Documents 1 and 2, there is a risk that the accessory may be finely scratched during storage. rice field. In addition, although the connected fastener is used as part of accessories, it lacks decorativeness.

Patent Document 4 discloses a connecting member (female portion) having a special shape and a connected member (male portion) used for this connecting member. The insertion opening of the female part is provided on the thumb side when the user holds the female part. The male part spreads out in a Y shape at its tip and has an elliptical plate-like body perpendicular to the Y shape. A shaft, which is a separate member, is attached to the inside of both ends of the Y-shaped portion, and the Y-shaped portion and the shaft form a connecting hole.

The male part of Patent Document 4 picks up the body part perpendicular to the Y shape. Easy to hold because there are no mounting holes where you pick it up. However, since the trunk portion is plate-shaped, it is slippery like the connected fastening member described in Patent Document 1 and the like. In particular, this fastener is configured so that the insertion direction of the male portion is parallel to the lateral direction of the body portion. Therefore, when the shaft of the male portion is brought into contact with the open/close member of the female portion and an upward force is applied during the insertion operation, the shaft side of the male portion slides to rotate downward and cannot be connected well. The shaft of the male portion and the Y-shaped portion are separate members, and the rod-shaped shaft is supported only at two points inside the tip of the Y-shaped portion. Therefore, when the linear member is pulled, the force is concentrated only at the two support points. As a result, it is conceivable that the round bar-shaped shaft will be bent, the space on the tip side of the Y shape will be expanded, and the like, and that the shaft will come off and the accessory will be lost.

Here, in the invention according to Patent Document 4, the female part having a specific shape is an essential component, and substitution with other connected fasteners (for example, pull ring type) is not considered. Therefore, when used in combination with, for example, a pull ring, the thick Y-shaped portion interferes with alignment, making it difficult to connect easily. Furthermore, the male part has a more complicated structure than conventional connecting plates, etc., and the Y-shaped part has a certain thickness to support the round bar. It was expensive. In addition, the Y-shaped portion of the male portion has an angular shape, and it is difficult to say that decorativeness is taken into consideration.

The accessory connecting fastening member of the present disclosure has been invented in view of the above-described problems, and is easier to connect to the connecting fastening member than the conventional connecting plate or other linked fastening member. It is possible. Hereinafter, an example of a preferred embodiment of a connected fastening member for an accessory of the present disclosure will be described together with an accessory and a fastening member for an accessory with reference to the drawings.

It is formed so that the width (the interval between the outer circumference 51a and the inner circumference 53a) is substantially constant. In addition, the tip position of the rear end portion 51X is the same as the central position of the mounting hole 53 in the longitudinal direction of the connecting member 40, and the central angle of the arc-shaped rear end portion 51X is approximately 180°C. be. Two plate surfaces facing each other in the front-rear direction of the knob tip portion 55 are flat surfaces. The width of the knob tip portion 55 in the vertical direction (the vertical direction in FIG. 3) is formed so as to gradually decrease from the rear end side to the tip side.

The connecting portion 70 is a portion that connects the other member (the connecting member 30) of the fastener 20. As shown in FIG. The connecting portion 70 is a plate-like portion having a constant thickness, as shown in FIG. An outer circumference 70a of the connecting portion 70 is a substantially U-shaped curve as shown in FIG. The connecting portion 70 has a connecting distal end portion 71 that is a C-shaped portion on the distal end side of the connecting portion 70 and a connecting rear end portion 75 that is a trapezoidal portion on the rear end side of the connecting portion 70 .

In the present embodiment, as shown in FIG. 4, the connecting hole 73 is a substantially circular through hole in a plan view, and the through hole passes through substantially the same direction as the thickness direction of the plate-like connecting portion 70. be. In the connecting tip portion 71, the outer circumference 71a of the tip side portion 71Y excluding both end portions of the C-shaped connecting tip portion 71 has an arc shape substantially concentric with the inner circumference 73a of the connecting hole 73, and the width in the radial direction (outer circumference 71a and the inner circumference 73a) is substantially constant. In addition, the rear end position of the tip side portion 71Y is located on the rear end side of the central position of the connecting hole 73 in the longitudinal direction of the connecting member 40, and the center angle of the arc-shaped tip side portion 71Y is 180°C. bigger than Two plate surfaces of the connecting rear end portion 75 that face each other in the vertical direction are flat surfaces. Further, the width of the connecting rear end portion 75 in the front-rear direction is formed so as to gradually decrease from the front end side to the rear end side.

As shown in FIG. 2 and the like, the connecting member 40 is formed so that the diameter of the connecting hole 73 that connects the connecting member 30 is larger than the diameter of the attachment hole 53 of the knob 50. The width of the portion 70 in the longitudinal direction is greater than the width of the knob portion 50 in the vertical direction. In addition, the plate-shaped knob tip end portion 55 is formed to be longer in the longitudinal direction (horizontal direction in FIG. 3) than the plate-shaped connection rear end portion 75 .

As shown in FIG. 2, an axis X parallel to the through-hole direction of the mounting hole 53 and passing through the center of the mounting hole 53 and an axis Y parallel to the through-hole direction of the connecting hole 73 and passing through the center of the connecting hole 73 are twisted. (relationship of twist positions), and a straight line perpendicular to both axes X and Y is substantially parallel to a straight line passing through the center of the mounting hole 53 and the center of the connecting hole 73 . Here, "substantially parallel" includes not only a strictly parallel state but also a nearly parallel state, for example, a range up to about ±30° with respect to the parallel state. Further, in the present embodiment, the angle formed by both axes X and Y is formed to be approximately 90°. As described above, the mounting hole 53 and the connecting hole 73 are formed such that the penetrating directions are the thickness direction of the knob portion 50 and the thickness direction of the connecting portion 70, respectively. Therefore, the angle formed by both axes X and Y is the same as the angle formed by the plate surface of the knob portion 50 and the plate surface of the connecting portion 70 .

The connecting portion 60 is a portion that connects the knob portion 50 and the connecting portion 70 having different normal directions to the plate surface. As shown in FIGS. 2 to 5, the connecting portion 60 has a shape obtained by twisting a substantially rectangular plate-like member having a substantially constant thickness. , the twist angle is formed to be approximately 90° from the knob portion 50 side toward the connecting portion 70 side. The torsion axis of the connecting portion 60 is on the same straight line as the center axis Z extending in the longitudinal direction of the knob portion 50 and the connecting portion 70 . Note that the term "substantially rectangular" refers to a rectangle or a state close to a rectangle, and is not limited to one in which the four interior angles are each right angles, but also includes one that can be determined to be rectangular as a whole. For example, some sides that are judged to be rectangular as a whole may have an uneven portion, a curved portion, or the like. In the example shown in FIG. 2, the direction of twist is clockwise from the side of the knob 50 toward the side of the connecting portion 70, but this is not restrictive and may be counterclockwise. .

The thickness of the connecting portion 60 is substantially the same as the thickness of the knob portion 50 and the connecting portion 70 . Also, the width of the connecting portion 60 (the length of the long side in the longitudinal section) is formed so as to gradually decrease from both ends connected to the knob portion 50 or the connecting portion 70 toward the approximate center.

Here, as shown in FIGS. 2 and 5, the two twisted inclined surfaces 62 extend from the rear end side (knob portion 50 side) to the tip end side (connecting portion 70 side) on the plate surface of the knob portion 50. On the other hand, the protruding surface protrudes in the front-rear direction, and is formed so that the protruding height gradually increases. The upper portion of the twisted inclined surface 62 on the front side curves so as to gradually turn forward toward the tip side (connecting portion 70 side), and the lower portion of the twisted inclined surface 62 on the back side curves toward the tip side. It has a curved shape so that it can be gradually turned backwards toward.

As shown in FIG. 2 and the like, the connecting member 40 has a notch portion 80 formed by notching a side surface thereof. The notch portions 80 are provided at four locations near the inclination start position 64 (that is, near the boundary between the knob portion 50 and the connecting portion 60 and near the boundary between the connecting portion 70 and the connecting portion 60). It is formed so as to be punched out in the thickness direction of the connection fastening member 40 . Here, the vicinity means a position where the position where the notch portion 80 is provided can be said to be close to the inclination start position 64 in relation to the overall shape of the connecting fastening member 40 . Specifically, when the notch 80 is provided in the knob 50, the notch 80 represents a position closer to the connecting part 60 than the position at which the central axis Z direction of the knob tip 55 is approximately 1/2. , it indicates a position on the connecting portion 60 side of a position that is approximately 1/2 of the connecting rear end portion 75 in the central axis Z direction. When the cutout portion 80 is provided in the connecting portion 60, it indicates a position closer to the knob tip end portion 55 side or the connecting rear end portion 75 side than the position at which the connecting portion 60 is approximately 1/2 in the central axis Z direction.

(Manufacturing of connected fastening member)
Next, a manufacturing process of the connected fastening member 40 according to the present disclosure will be described with reference to FIG. The connecting fastening member 40 is manufactured by processing a flat metal plate (not shown). First, a flat plate-shaped punched member 90 having the above-described two through holes (mounting hole 53 and connecting hole 73) and four notches 80 is produced by punching from a flat plate. Next, the punched member 90 is placed in a mold (not shown) and twisted to produce a twisted member 90X. In the twisting process, it is twisted to a predetermined twisting degree (twisting angle). After the twisting process, the twisting process member 90X may be polished to remove corners. Alternatively, the punched member 90 may be ground before being twisted to produce a ground member (not shown), and the ground member may be twisted. The punched member 90 may be used as the connecting member 40 as it is. As described above, the connected fastening member 40 is manufactured. The manufacturing process of the connecting member 40 is not limited to this, and includes, for example, a casting method in which molten metal is poured into a mold, a forging method in which metal is beaten, and a metal 3D process using metal powder or molten metal. A 3D printing modeling method that manufactures with a printer can be mentioned.

According to the to-be-connected fastening member 40 which is an example of the present embodiment, it is provided with a tabular knob portion 50 having a mounting hole 53 penetrating in the thickness direction, and a connecting portion 70 having a connecting hole 73. and the central axis Y of the connecting hole 73 are in a torsional relationship. In other words, the normal direction of the tabular knob portion 50 is not the same direction as the through-hole direction of the connecting hole 73 . Therefore, when performing the connecting operation on the back side of the neck, it is possible to reduce the degree of twisting of the hand and arm holding the connecting fastening member 40, or eliminate the need to twist it. In addition, by twisting only one hand holding the connecting member 30, the tips of the fingertips of both hands can be avoided from hitting each other from the front, and the space created between the tip of the thumb and the tip of the index finger of both hands can be utilized. can be easily connected.

In the present embodiment, the angle between the central axis (axis X) of the mounting hole 53 and the central axis (axis Y) of the connecting hole 73 is approximately 90°, but the angle is not limited to this. However, from the viewpoint of facilitating the connecting operation of both fastening members 30 and 40, the angle between the central axis of the mounting hole 53 and the central axis of the connecting hole 73 may be 60° or more and 120° or less. The lower limit of this angle is preferably 70° or more, more preferably 80° or more. Also, the upper limit of this angle is preferably 110° or less, more preferably 100° or less. From a similar point of view, the angle between the plate surface of the knob portion 50 and the plate surface of the connecting portion 70 may be 60° or more and 120° or less. The lower limit of this angle is preferably 70° or more, more preferably 80° or more. Also, the upper limit of this angle is preferably 110° or less, more preferably 100° or less.

In this embodiment, the entire connecting portion 70 is plate-shaped. Therefore, the peripheral thickness of the connecting hole 73 is constant. When inserting the tip of the connecting portion 70 into the opening 39 of the connecting member 30 while making fine adjustments, the insertion can be performed smoothly regardless of the direction of insertion, which facilitates connection. Although the connecting portion 70 is not limited to a plate shape, it is preferable that the thickness of the insertion portion 71X (see FIG. 4) on the distal end side of the geometric center of the connecting hole 73 is constant at least in the longitudinal direction. . In addition, as will be described later (see paragraph 0047), considering the case where the member to be connected and fastened 40 is held in a direction different from the orientation of the fingertip, the entire connecting tip portion 71 has a plate shape with a constant thickness. is more preferred. Note that, in the present disclosure, both “constant” and “substantially constant” are concepts that include both a constant state and a nearly constant state. Similarly, in the present disclosure, the term "substantially" is a concept that includes that state and a state close to that state.

In this embodiment, the diameter of the connecting hole 73 is formed larger than the diameter of the mounting hole 53 from the viewpoint of easily performing the connecting operation of the both fastening members 30 and 40 . The size of the diameter of the connecting hole 73 is not limited to this, and may be any size that allows the connecting operation to be performed. Further, in the present embodiment, the shapes of the mounting holes 53 and the connecting holes 73 are not limited to substantially circular shapes. Further, in the present embodiment, the knob 50 does not necessarily have the attachment hole 53 , and an extension may be provided on the rear end side of the knob 50 and the attachment hole 53 may be provided in the extension.

The connecting portion 60 has a rising surface rising from the plate surface of the knob portion 50 . The raised surface serves as a position for the user to hold the knob 50 of the connecting fastening member 40, and the tip of the finger comes into contact with the raised surface, so that the finger can move toward the tip (longitudinal side) when performing the connection operation. direction) and acts as a non-slip to prevent slipping. Also, if the rising surface is an inclined surface that is twisted in the longitudinal direction, it conforms to the curved surface of the tip of the fingertip and is easy to hold. Note that the shape of the connecting portion 60 is not limited to that described above, and may have a raised surface that functions as a non-slip to prevent the finger from slipping toward the distal end. For example, the connecting member 40 is arranged such that only the knob portion 50 and the connecting portion 70 having the above-described shape are arranged in the longitudinal direction so that the relationship between the normal line of the knob portion 50 and the axis of the connecting hole 73 is twisted. Alternatively, the end surface of the knob portion 50 on the front end side and the end surface of the connecting portion 70 on the rear end side may be in contact with each other. As in this case, the connecting portion 60 may be omitted.

In this embodiment, the connecting portion 60 has two twisted inclined surfaces 62 that continuously twist and tilt from the end of the knob 50 on the connecting portion 60 side toward the end of the connecting portion 70 on the connecting portion 60 side. have. The two twisted inclined surfaces 62 have curved portions that are turned in opposite directions. When the knob part 50 is pinched, the curved parts that are turned up in two protrude toward the abdomen of the two fingertips, so that the connecting member 40 can be prevented from slipping in the lateral direction. can. Further, the side surface of the connecting rear end portion 75 can be held by both fingernails so that the side surface of the connection rear end portion 75 is brought into contact with the fingernails. Therefore, even if the connecting member 40 collides with the connecting member 30 or the like during the connecting operation, it is less likely that the connecting member 40 will slip and move. In addition, even if it collides and moves, the position of the side surface of the connecting rear end portion 75 can be confirmed with a fingertip, and the position of the connecting hole 73 can be estimated. Furthermore, since the position of the connecting hole 73 can be estimated, for example, it is possible to hold the member to be connected 40 so that the connecting hole 73 protrudes in the direction opposite to the back side without aligning the longitudinal direction of the member to be connected 40 with the direction of the fingertip. . By holding it in this way, it is possible to avoid colliding fingers and tangling of hair during connecting operations. Also, in this case, since the direction of insertion of the connecting member 30 into the opening 39 (see FIG. 7) deviates laterally from the distal end of the peripheral edge of the connecting hole 73, the peripheral edge of the connecting hole 73 is kept constant over a wide range. is preferable.

In this embodiment, the knob 50 is provided with the mounting hole 53, the diameter of which is relatively large, approximately half the length of the knob 50 in the longitudinal direction (horizontal direction in FIG. 3). When pinched with the fingertips, for example, the round ring attached to the attachment hole 53 is pressed against the ball of the finger to exhibit a non-slip function. In addition, the positional relationship between the circular ring and the connecting portion 60 can be sensed with a fingertip, making it easy to guess the orientation of the connecting fastening member 40 and the position of the connecting hole 73 . In addition, the proportions of the knob portion 50, the connecting portion 60, and the connecting portion 70 in the longitudinal direction of the connected fastening member 40 for accessory are not particularly limited. From the standpoint of facilitating the connecting operation of accessories, the connecting portion 60 is preferably in the range of about 1/5 to about 1/3 of the overall length in the longitudinal direction.

Both ends of the connecting portion 60 are inclined starting positions 64, and the twisted inclined surface 62 of the connecting portion 60, the plate surface of the knob portion 50, and the plate surface of the connecting portion 70 are smoothly continuous surfaces. . Therefore, in the case of a bracelet that is connected with one hand, the tip of the connecting member 30 can be guided into the connecting hole 73 along the twisted inclined surface 62 by using the turned-up portion of the twisted inclined surface 62 . .

The accessory connecting fastening member 40 of the present disclosure has a twisted inclined surface 62 that reflects light from multiple directions and sparkles, and is also excellent in decorativeness. Without giving too much presence, it fits well with the other members of the accessory and prevents it from interfering with the design of the accessory. Therefore, it can be used for various accessories. In addition, since it becomes possible to easily connect and separate the accessories, in combination with any type of connection fastening member for accessories (for example, a fastening member typically represented by a pull ring type), A single fastener is also possible and has the advantage of being excellent in versatility.

The accessory connected fastening member 40, which is an example of a preferred embodiment of the present disclosure, is integrally molded as a whole, so that it is hard to break and loss of the accessory during use can be suppressed. In addition, since the shape can be formed by punching and twisting, the labor and time required for manufacturing can be reduced. On the other hand, the strength of the conventional connection plate member manufactured by punching is decreased when the thickness is reduced, so that the shape retention of the connection plate may be low. On the other hand, the connection fastening member 40 for accessories can be twisted to give strength to the connecting portion. The cost of materials used can be reduced. In addition, it is believed that the reduced weight and reduced torsional contact surface with the body will reduce the movement of the connected fasteners from the back toward the face during use. Note that the notch 80 is not an essential component, but by providing the notch 80 before twisting, it is possible to reduce the risk of the member cracking or breaking during the twisting process.

Next, the connection fastening member 30 of the form shown in FIG. 1 will be described. FIG. 7 is a perspective view of the closed connecting member 30 shown in FIG. 1 in an open state. 1 and 7 includes a first member 31 having an operation portion 32 and a second member 35 that rotatably supports the first member 31 . The tip of the first member 31 is curved downward (that is, the direction toward the second member 35), and the tip of the second member 35 is curved upward (that is, the direction toward the first member 31). , the first member 31 and the second member 35 form a closed holding space 37 inside. By operating the operation part 32 provided on the rear end side of the first member 31 to open it, the front end side of the first member 31 opens widely, and an opening part 39 leading to the holding space 37 is formed. . The connecting portion 70 of the member to be connected and fastened 40 is inserted into this gap (opening portion 39), the holding space 37 is used to latch the connecting hole 73, and the operating portion 32 is returned to the original position, whereby the member to be connected and fastened 40 are concatenated.

The connecting member 30 described above has a configuration in which the front end side is open, and the rotation shaft (not shown) is provided at the rear end side, so that the opening portion 39 when in the open state can be It is large compared with the connection fastening member (for example, patent documents 2, 4, etc.). By combining with the connected fastening member 40 according to the present disclosure and using it as a fastener for an accessory, the user of the accessory can easily connect and separate the fastener.

Also, the opening 39 of the connecting member 30 is formed on the tip side opposite to the side on which the chain is attached. The insertion direction when inserting the connecting portion 70 of the connecting member 40 into the openable opening 39 leading to the holding space 37 is substantially perpendicular to the penetrating direction of the connecting hole 73 of the connecting member 40 . becomes (see Fig. 1). Since the direction of the straight line that connects the tip end side of the first member 31 and the tip end side of the second member 35 of the opening 39 in the open state is substantially parallel to the thickness direction of the connecting portion 70, the connecting portion can be fastened. Member 40 can be easily inserted into coupling member 30 . Note that “substantially perpendicular” includes not only a strictly perpendicular state but also a nearly perpendicular state, for example, a range up to about ±30° with respect to the vertical.

Note that the connection fastening member to be combined with the connection fastening member 40 according to the present disclosure is not limited to this, as long as it can detachably hold the connection hole 73 . For example, a fastening member 120 of the form shown in FIG. 8 may be used, or another form of fastening member (for example, the fitting for accessories disclosed in Patent Document 2) may be used. On the other hand, with the pull ring 120 shown in FIG. 8, there were cases where the tip of the finger (nail) came off the opening lever 122 and the open state could not be maintained. In such a case, the user of the accessory may find it difficult to perform the connecting operation of the fastener for the accessory because the user has to return the hand that was brought to the back of the neck and redo the connecting operation. be. For this reason, it is preferable to apply the above-described connection fastening member 30 as the connection fastening member to be combined with the connected fastening member 40 according to the present disclosure.

A preferred example of the embodiment of the present disclosure has been described above, but the specific configuration is not limited to this, and various modifications can be made without departing from the gist of the present disclosure.
