Patent Document 1: Utility New Case Bulletin No. Sho 58-42412

When the needle-shaped or sword-shaped shank illustrated in the claw of Patent Document 1 is inserted through the fabric, the sharpness of the shank is ensured in order to prevent the wrinkles from being generated on the fabric (in other words, the performance of cutting the fabric) Become important. However, there are various reasons why it is impossible to ensure the sharpness of the handle. For example, when the handle is made of a resin, the sharpness is lowered and lowered as compared with the case of a metal. In this case, during the process of the shank passing through the fabric, the fabric advances along with the shank (that is, the cloth is pulled in by the shank), so that wrinkles are formed around the button around the button. Further, the main causes for lowering the sharpness of the shank are various and are not limited to the constituent materials. Furthermore, the present invention is also applicable to the case where the sharpness of the shank is ensured, and the description of the subject matter is not to be construed as limiting the invention.

As apparent from the above description, it is desirable to suppress the occurrence of wrinkles on the sheet when the sheet exemplified by the stalk portion is passed through the cloth or the like.

The fixture according to the present invention is configured to connect a fixed object disposed on the other side surface of the sheet from one side surface of the sheet, and includes a fixture body including a base portion and a handle provided on the base portion. And a peripheral body that is disposed integrally or separated from the fixture body and that surrounds at least a portion of the front end side of the handle portion, the peripheral body having a front end that is separated outwardly from the front end portion of the handle portion.

When the shank of the fixture body penetrates the sheet, the sheet is sandwiched between the peripheral body and the fixed object to suppress displacement of the sheet and suppress generation Wrinkled in the thin sheet. Further, the relationship between the timing at which the shank portion abuts against the sheet and the timing at which the peripheral body abuts against the sheet is arbitrary, regardless of whether the former is earlier or later than the latter. The fixed object is, for example, a button body, but is not limited thereto. The sheet is, for example, a cloth, but is not limited thereto. A wide variety of variations are possible, and this point will be more specific by the description below.

In the method for fixing a fixed object to a sheet according to the present invention, the fixture body, the sheet, and the fixed object are disposed in sequence; the fixture body is provided with a peripheral body that at least partially surrounds the front end side of the handle portion. The interval between the narrow fixture body and the fixed object, in the process, in any order, the handle portion penetrates the sheet, and the front end portion of the outer body body is pressed against the fixed object through the sheet, so that the outer body is fixed on the fixture body and fixed The object is deformed between the objects, and the front end portion of the shank is deformed on the side of the fixed object in order to connect the fixture main body and the fixed object to each other in a state in which the sheet is sandwiched.

The outer periphery of the present invention includes a base portion and a shank portion provided on the base portion, and the shank portion is inserted through the sheet from one side surface of the sheet, and is produced on the side of the fixed object disposed on the other side surface of the sheet. Deformation, thereby attaching the fixture body connected to the fixed object, comprising: a tubular portion extending along the extending direction of the handle portion and spaced apart from the handle portion; and a position fixing portion disposed at a lower end of the tubular portion The side abuts against the outer peripheral surface of the handle to position the handle. Preferably, the inner diameter of the tubular portion is wider than the opening diameter of the opening provided in the position fixing portion. The opening diameter of the opening of the position fixing portion is narrower than the inner diameter of the cylindrical portion, so that the outer body appropriately positions the shank portion set. Further, the inner diameter of the tubular portion is wider than the opening diameter of the opening of the position fixing portion, and the partial portion of the sheet existing around the shank portion can be appropriately pressed by the distal end of the anti-wrinkle.

The button of the present invention comprises: a button body, a fixture (the above-mentioned fixture and the above-mentioned fixture provided with a peripheral body), the fixture body of the fixture and the button body are shank provided by the base portion of the fixture body After passing through the sheet, the button body is deformed to be coupled to each other, and between the sheet and the base portion of the fixture body, a peripheral body is disposed around the handle portion, and the peripheral body follows the button body and the fixture body. The interval between them is reduced to cause deformation.

According to the present invention, when the shank portion is passed through the sheet exemplified by the cloth or the like, it is possible to suppress the sheet from being introduced by the shank portion and causing wrinkles on the sheet.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiments are not independent of each other, and therefore, it is not necessary to over-describe, and as long as they are in the field, they can be appropriately combined, and the multiplication effect by the combination can be maintained. The repeated explanation between the embodiments is omitted in principle.

The drawings for the description of the embodiments are based on the description of the invention, and are therefore simplified as appropriate. In these drawings, the central axis AX is appropriately set. The central axis AX, for example, is identical to the latter by the handle The part penetrates the direction of the cloth, but is not limited thereto. For example, as is clear from the drawing, the central axis AX also coincides with the direction in which the handle extends. And the central axis AX is also consistent with the mounting direction between the female snap and the male snap. In the following description, for convenience, the direction close to the central axis AX is referred to as the inner side, and the direction separated by the central axis AX is referred to as the outer side. The term "top view or bottom view" means that each includes a view from the upper side or the lower side along the central axis AX.

In the drawings, XYZ coordinates which are orthogonal to each other are appropriately set. The X axis is the lateral direction, which corresponds to the left and right direction and also corresponds to the radial direction. The Y axis is consistent with the central axis AX and is longitudinally corresponding to the up and down direction. The Z axis is the depth direction, which corresponds to the front and rear direction.

<First Embodiment>

The first embodiment will be described with reference to Figs. 1 to 7 . Further, the male and female snaps are attached to the fabric via the procedures of FIGS. 1 , 3 , 4 , 5 , and 6 . First, the state before the male and female snaps are attached to the fabric will be described with reference to Figs. 1 and 2 .

The male and female snaps 90 shown in Fig. 1 are male snaps and are attached to the fabric 100 (in addition, since the fabric is a sheet-like member, it is also called a sheet). The cloth 100 is, for example, a fabric in which natural fibers, chemical fibers (for example, polyester or nylon fibers) are woven in a plane, but is not limited thereto, and may be made of non-woven fabric, natural or A sheet formed of a resin material such as synthetic leather, felt, or plastic.

As shown in Fig. 1, the male and female snaps 90 are installed in front of the fabric 100, and the male and female snaps 90 have: a fixture body 10; an anti-wrinkle device (wrinkle prevention means or a peripheral body) 30, located on the lower side of the fabric 100; and the fastener 20 as a button body (fixed or mounted object) and located on the upper side of the cloth 100. Even after the male and female snaps 90 are attached to the fabric 100, basically, the foregoing contents are not changed (refer to Fig. 6). However, it can be clearly seen from FIGS. 5 and 6 that the shank portion 13 of the fixture body 10 is interstitial to the fastener member 20 after penetrating the fabric 100 and inserting the opening of the fastener member 20 on the fabric 100. . Therefore, after the male and female snaps 90 are attached to the fabric 100, the fixture body 10 is partially present on the fabric 100.

It can be clearly seen from the comparison of Fig. 1 and Fig. 6 that after the male and female snaps 90 are attached to the fabric 100, the anti-wrinkle 30 is between the fixture body 10 and the fastener 20 (cloth 100), and does not remain as it is. Being squeezed. As will be apparent from the description below, in the present embodiment, the wrinkle prevention device 30 is provided on the side of the fixture main body 10, and is restrained on the cloth 100 by a mechanism (anti-wrinkle function of the anti-wrinkle device 30) which will be described later. Wrinkles are produced. Here, in order to achieve weight reduction of the male and female snaps 90, it is preferable that the fixture main body 10 and the fastener 20 are made of resin, and the anti-wrinkle 30 is also made of resin. For example, the fastener 20 is a resin such as polyacetal or polyester or polyamide, and the anti-wrinkle 30 may be a resin such as high molecular polyester or polyacetal. Here, the resin of the fastener 20 and the anti-wrinkle 30 have different resin hardnesses, and the anti-wrinkle 30 is softer (softer) than the resin of the fastener 20. When the shank portion 13 of the fixture body 10 is formed of a resin, the sharpness may be lowered to cause wrinkles on the cloth 100. However, according to the present embodiment, the cloth can be suppressed by the mechanism described later. Wrinkles occur on 100. Further, the material of the constituent members of the male and female snaps 90 is arbitrary, and is not limited to metal, resin, or the like. The anti-wrinkle 30 is more preferably made of a material suitable for plastic working, and undergoes irreversible deformation after being subjected to a force, and does not return to its original shape. On the other hand, the fixture body 10 and the fastener 20 are made of a material which is harder than the wrinkle prevention member 30 and further resistant to external force. Further, the external force above the limit of the shank portion 13 of the fixture body 10 is attached to the fastener 20 by the processing device.

As shown in Fig. 1, the fixture body 10 has a base portion 11 formed in a disk shape centered on the central axis AX, and an end portion 12 formed in a plan view annular shape centered on the central axis AX, and a shank portion 13 formed. A needle or sword shape extending upward along the central axis AX. The base portion 11 is formed by an arc extending from the center toward the outside to form a shallow recess. The end portion 12 is a convex portion that is formed to protrude upward, and is provided on the outer circumference of the base portion 11. When the fixture body 10 is squinted from above, the concave recess 17 is provided around the shank portion 13. As is clear from the comparison of Fig. 4 and Fig. 5, the recessed portion 17 functions as a housing portion for accommodating the anti-wrinkle tool 30. The anti-wrinkle 30 is finally crushed by being pinched in the up and down direction between the fixture body 10 and the fastener 20. As shown in Fig. 5, the wrinkle holder 30 is completely squashed and housed in the recessed portion 17, so that the engagement between the fixture fabric 100 and the fastener 20 can be more complete.

Further, the upper surface 11a of the base portion 11 is an inclined surface that is gradually inclined upward toward the outside from the central axis AX. The upper surface 12a of the end portion 12 is a flat surface extending along an axis orthogonal to the central axis AX.

The shank portion 13 shown in Fig. 1 has a needle-shaped body (further, also referred to as a cylindrical member) which is processed into a sharp small diameter, and is vertical. Starting from the upper surface 11a of the base portion 11. The shank portion 13 has a shank base portion 13a that is connected to the base portion 11, and a shank front end portion 13b that is provided at an upper portion of the shank base portion 13a. The shank base 13a is extended upward by a certain diameter. The shank front end portion 13b is formed to extend upward to reduce its diameter. Further, the structure of the shank front end portion 13b is not necessarily limited to the structure shown in Fig. 1 as long as the sharpness can be ensured. For example, the tip end of the shank portion 13 is recessed into a bowl shape to ensure sharpness.

The fastener 20 shown in FIG. 1 has a base portion 21, an end portion 22, a convex portion 23, a tubular portion 25, and a locking portion 26. The base portion 21 is a disk-shaped member having the central axis AX as a center, and has a thick portion having a thickness W1 on the inner side and a thin portion (thickness W1 > thickness W2) having a thickness W2 on the outer side. The end portion 22 is a ring-shaped portion in a plan view with the central axis AX as a center, and is provided on the outer circumference of the base portion 21. The convex portion 23 is provided under the thick portion of the base portion 21, for example, formed in a ring shape in a bottom view. The tubular portion 25 is an engaging portion that is a male snap to receive the female snap, and is a portion that engages the female snap. The locking portion 26 is provided on the outer peripheral surface of the tubular portion 25 and has a convex shape, and the locking portion as a male snap engages the locking portion of the female snap. In addition, it is conventionally known that when the male snap engages the female snap, the engaging portions of the two sides (or the tubular portion 25 if the male snap is) are elastically deformed, and then, by elastically returning to the original shape, the two sides are mutually engaged. stop.

As shown in Fig. 1, the base portion 21 is provided with an opening 27 around the central axis AX. The opening diameter W27 of the opening 27 is formed to have an appropriate width for the insertion of the shank portion 13, and is set to be slightly wider than the diameter W13 of the shank portion 13, for example. As shown in Fig. 1, the tubular portion 25 is provided with an internal space 28. The interior The space is for accommodating the locking portion 13c of the shank portion 13 which is pressed as shown in Fig. 6. The diameter W28 of the inner space 28 is a schematic view as shown in Fig. 7 formed to a suitable width for receiving the guide cylinder 201 of the upper mold 200, for example, set to be substantially the same as or slightly narrower than the outer diameter W201 of the guide cylinder 201. . Further, as in the upper mold 200 shown in Fig. 7, the punch 202 is disposed so as to be movable up and down in the guide cylinder 201 to constitute a part of the mounting device. When the punch 202 is lowered, the front end of the shank portion 13 penetrating the cloth 100 is deformed to fill the fastener 20. Further, as shown in Fig. 1, the upper surface of the base portion 21 is provided with a recess 29 for accommodating a part of the female snap. The recess 29 is, for example, extended in a ring shape in plan view to continuously surround the tubular portion 25.

As shown in Fig. 1, the anti-wrinkle 30 is used to surround the shank 13 and positionally fix the shank 13 (locked by friction). The wrinkle prevention device 30 can be gripped as a peripheral body surrounding the handle portion 13. It is preferable that the wrinkle prevention device 30 is attached to the shank portion 13 such that the upper end position of the crease prevention tool 30 is slightly higher than the apex position of the shank front end portion 13b, but the invention is not limited thereto. For example, in the schematic view shown in Fig. 1, the front end position of the wrinkle prevention device 30 is only higher than the front end position of the shank portion 13 by a space W31. By disposing as described above, it is possible to ensure that the wrinkle prevention device 30 comes into contact with the cloth 100 before the handle portion 13 comes into contact with the cloth 100, and wrinkle prevention can be achieved more effectively. Further, the position of the wrinkle prevention device 30 on the shank portion 13 in the longitudinal direction of the shank portion 13 is arbitrary. For example, the first figure may be observed, and the crease prevention tool 30 may be disposed on the base portion 11. That is, the front end portion of the shank portion 13 (the shank front end portion 13b) is made of the anti-wrinkle tool at the front end side of the shank portion 13 by the same position as the front end portion of the shank portion 13 or by a slight decrease thereof. 30 exposed. However, the interval in the height direction between the front end of the shank front end portion 13b and the upper end surface 33 of the crease preventing tool 30 is preferably smaller than the thickness of the cloth. It is also possible to make the upper end position of the wrinkle preventing member 30 lower than the apex position of the shank front end portion 13b. The wrinkle prevention device 30 is not attached to the handle portion 13, but is another portion of the fixture body 10, and may be attached to the base portion 11, for example.

As shown in FIG. 1, the inner diameter W23 of the convex portion 23 of the fastener 20 is set to be wider than the outer diameter W30 of the anti-wrinkle device 30. Thereby, the convex portion 23 functions as a positioning means of the anti-wrinkle tool 30, and the range or aspect in which the fastener 20 is pressed from below by the fabric 100 can be optimized by the anti-wrinkle tool 30. The specific configuration of the convex portion 23 is not limited as long as the point for positioning the front end of the anti-wrinkle device 30 is arbitrary, and does not necessarily have to be extended into a ring shape. If the shape of the wrinkle prevention device 30 is a rectangular shape, the shape of the convex portion 23 may be formed in a rectangular shape in accordance with this case. The convex portion 23 does not necessarily need to be continuous in a plane, and may be arranged to be divided in a plane.

The structure of the anti-wrinkle 30 will be described with reference to Fig. 2 . As is clear from FIG. 2, the wrinkle prevention tool 30 includes a tubular portion 31 for surrounding the shank portion 13 and a bottom portion 32 provided at a lower end of the tubular portion 31. The upper end surface 33 of the tubular portion 31 is annular in plan view, and is disposed outside the shank front end portion 13b of the shank portion 13 and spaced apart from each other. More specifically, the tip end of the tubular portion 31 is formed in a continuous annular shape by the tip end of the shank portion 13 being spaced apart from each other at a substantially constant interval in the radial direction. The outer diameter of the tubular portion 31 is reduced toward the lower side, whereby the inclined surface 31a is formed. That is, the tubular portion 31 has a structure that is narrowed downward. When the compression force from the vertical direction is generated in the tubular portion 31, the tubular portion 31 can be deformed as shown in the schematic diagram of the dotted line shape shown in Fig. 2 ( The modified form of the anti-wrinkle device 30 shown in Fig. 2 is an example thereof, and is not limited thereto. Further, the modified form of the anti-wrinkle 30 is expected to be affected by various main bodies such as the state in which the wrinkle preventing member 30 is attached to the shank portion 13.

As shown in FIG. 2, the opening diameter W36 of the opening 36 provided in the bottom portion 32 is narrower than the diameter W37 of the internal space 37 of the tubular portion 31 (that is, the inner diameter of the tubular portion 31). In other words, the inner diameter W37 of the tubular portion 31 is wider than the opening diameter W36 of the opening 36. Further, the inner diameter (opening diameter) W37 of the tubular portion 31 is wider than the inner diameter W27 of the opening 27 of the fastener 20 (refer to Fig. 1). The opening diameter W36 of the opening 36 of the bottom portion 32 is set to such an extent that the wrinkle prevention device 30 can be locked to the shank base portion 13a. When the crease prevention member 30 is attached to the shank portion 13, the bottom portion 32 abuts against the outer circumferential surface of the shank base portion 13a, whereby friction is generated therebetween, for example, so that the crease prevention member 30 is at the shank portion 13 and the tubular portion 31. The shank portion 13 is attached to a state in which a gap is maintained between the inner circumferential surfaces. The bottom portion 32 functions as a position fixing portion or a position fixing means for fixing the position on the shank portion 13 of the crease preventing tool 30.

As apparent from the above description, the male and female snaps 90 in the exploded state shown in Fig. 1 are attached to the fabric 100 in the order of Fig. 3, Fig. 4, Fig. 5, and Fig. 6. Hereinafter, the procedure for attaching the male and female snaps 90 to the fabric 100 will be described with reference to the above drawings.

First, as shown in Fig. 1, the fixture main body 10 to which the wrinkle prevention tool 30 is attached in advance is placed on a lower mold (not shown). Next, the cloth 100 is placed above the fixture body 10. Next, the fastener 20 held at the front end of the guide cylinder 201 is placed on the cloth 100. At this time, the handle 13 and the opening 27 are arranged by any method and are located on the same straight line. on. Thereafter, as shown in FIG. 3, in a state where the cloth 100 is placed on the wrinkle prevention device 30, the fastener 20 held by the guide cylinder 201 is lowered. In this process, as shown in FIG. 3, the anti-wrinkle tool 30 presses the cloth 100 upward, so that the cloth 100 is formed between the upper end surface 33 of the wrinkle prevention device 30 and the lower surface of the fastener 20 by the vertical direction. In addition, the lowering of the fastener 20 is performed by the lowering of the upper mold having the guide cylinder 201. The lowering of the upper mold is performed by inputting an operation command to the device including the upper mold. The manufacturing steps are generally performed by the cooperation of human and manufacturing machines.

Next, when the lowering of the upper mold 200 is continued, as shown in the fourth diagram, the cloth 100 is opened by the cleavage of the shank portion 13. In the present embodiment, in the state from the third figure to the fourth figure, the wrinkle prevention device 30 presses the cloth 100, and the cloth 100 is fitted between the wrinkle prevention device 30 and the fastener 20 in the vertical direction. With this embedding, it is expected that the position of the cloth is fixed within the range of embedding (additional or alternative, in the range of embedding, a state in which the cloth is laid). By causing the shank portion 13 to pass through the cloth 100 in this state, the cloth 100 is prevented from advancing with the shank portion 13, whereby wrinkles can be suppressed from occurring on the cloth 100 to which the male and female snaps 90 are attached. It is also expected that the penetration of the cloth 100 by the shank portion 13 can be promoted by the holding of the cloth by the cooperation of the above-described wrinkle prevention device 30 and the fastener 20.

The lowering operation of the upper mold 200 is continued after the shank 13 is inserted through the fabric 100. As shown in Fig. 5, the upper surface of the end portion 12 of the fixture body 10 and the lower surface of the end portion 22 of the fastener 20 are formed. Direct clamp Hold the state of the cloth 100. When the fastener 20 is disposed directly above the fixture body 10 via the cloth 100, the front end position of the shank front end portion 13b is located higher than the fastener 20, and the crease prevention tool 30 faces outward due to pressure from the up and down direction. Expanded or stretched, that is, extruded.

As is clear from Fig. 5, the anti-wrinkle 30 is completely flattened and stuffed between the fixture body 10 and the cloth 100. As described above, the space between the fixture main body 10 and the cloth 100 is filled by the anti-wrinkle tool 30, and the wrinkle prevention device 30 can function as a sealing material (or may be referred to as a packaging material). The male and female buckles 90 are fixedly attached to the fabric 100. By providing the recessed portion 17 in the fixture main body 10, the accommodation space of the crushed wrinkle prevention device 30 can be appropriately ensured, and the extension of the wrinkle prevention device 30 to the outside of the male and female snap fastener 90 can be suppressed. In particular, the fabric 100 is thin, and for example, even if the thickness of the fabric is 0.5 mm or less, the anti-wrinkle can be used as a sealing material to function properly, and the male and female snaps 90 can be appropriately fixed to the fabric 100.

As shown in Fig. 5, the width of the concave portion 17 in the radial direction coincides with the width W17 between the shank portion 13 and the end portion 12. The thick wall portion of the fastener 20 is disposed to correspond to the recess 17. Thereby, in the process of flattening the wrinkle prevention device 30, the wrinkle prevention tool 30 is sufficiently extended from the side of the shank portion 13 toward the end portion 12, and as a result, the male and female snaps 90 can be sufficiently adhered to the fabric 100. Further, the volume of the internal space S50 shown in Fig. 5 is selected in accordance with the balance of the above-described epitaxy and hermeticity.

Next, as shown in Fig. 6, after the punch 202 of the upper mold 200 is lowered, the front end portion of the front end portion 13b including the shank portion 13 is deformed into a width. It is the width W13c, whereby the handle 13 fills the fastener 20 (W28>W13c>W27). Further, in the process in which the shank portion 13 passes through the cloth 100 and passes over the cloth 100, it is considered that the cloth 100 is partially introduced into the gap S51. This gap is between the outer peripheral surface of the shank portion 13 and the open side surface of the base portion 21 of the fastener 20. Even in this case, as described above, by the holding of the cloth 100 by the cooperative action of the anti-wrinkle 30 and the fastener 20, wrinkles which are likely to cause problems can be suppressed. As apparent from the above description, in the present embodiment, wrinkles are prevented from being generated in the cloth 100 mainly by the operation of the wrinkle prevention device 30. In the present embodiment, it is not necessary to change the existing manufacturing equipment itself. In the present embodiment, it is mainly changed with the addition of the anti-wrinkle tool 30, and there is no burden of causing a problem from the viewpoints of steps, costs, and the like.

<Second Embodiment>

The second embodiment will be described with reference to Figs. 8 to 10 . As described at the outset, the description of the portions overlapping with the first embodiment will be omitted. In the present embodiment, unlike the first embodiment, the wrinkle prevention device is integrally formed on the base portion 11 of the fixture main body 10 so as to surround the shank portion 13. More specifically, as is clear from Fig. 8, the wrinkle preventing portion 18 corresponding to the anti-wrinkle device 30 of the first embodiment is integrally formed on the base portion 11 of the fixture main body 10. Even in the above case, the wrinkle prevention portion 18 exhibits the same function as the anti-wrinkle device 30, whereby the same effects as those of the first embodiment can be obtained. In the present embodiment, it is not necessary to attach the wrinkle prevention device 30 to the shank of the fixture body 10 as in the first embodiment. 13, can achieve the simplification of the installation steps.

As shown in Fig. 8, as in the first embodiment, the front end position of the wrinkle prevention portion 18 is set to be higher than the front end position of the shank portion 13. However, the present invention is not limited thereto, and the front end position of the wrinkle prevention portion 18 may be formed to be lower than the front end position of the shank portion 13.

The procedure for attaching the male and female snaps 90 to the fabric 100 will be described with reference to FIGS. 9 and 10. As shown in Fig. 10, the wrinkle preventing portion 18 is V-shaped during the flattening process. Even in the above case, the holding of the cloth 100 can be achieved by the cooperation of the wrinkle preventing portion 18 and the fastener 20. In the embodiment, the wrinkle prevention portion 18 is made of the same material as the base portion 11 and the shank portion 13, but the thickness of the wrinkle prevention portion 18 can be made thinner than the base portion 11 and the shank portion 13 And easy to deform. Further, the wrinkle preventing portion 18 may be finally extruded as shown in Fig. 5 of the first embodiment. The wrinkle-preventing portion 18 may be finally housed in the concave portion 17 of the fixture main body 10 in a state of being kept in its original shape. The thick wall, the height of the wrinkle prevention portion 18, and the interval in the radial direction of the shank portion 13 are set in accordance with individual conditions.

<Third embodiment>

The third embodiment will be described with reference to Figs. 11 to 13 . In the present embodiment, unlike the above-described first embodiment, as shown in FIG. 11, the convex portion 24 is further provided on the inner circumference of the convex portion 23, whereby the wrinkle prevention member 30 is protruded by the outer convex portion 23 and the inner convex portion.
