Description

[Technical Field]

[0001] The present invention relates to a button removal tool, and more particularly to a tool for removing a button made up of multiple parts attached to fabric by fastening members from the fabric. [Background technology]

[0002] Buttons made up of multiple parts, such as tuck buttons used on jeans and denim jackets, are known. FIG. 1 is a cross-sectional view showing an example of such a button in an exploded state, showing fabric f and a fastening member 10. FIG. 2 is a cross-sectional view showing button 1 attached to fabric f with fastening member 10. Button 1 comprises a body 2, which is an outer shell member, an insert 3 housed within body 2, and a cap 4 that closes a body head 2a of body 2 housing insert 3. Button 1 (see FIG. 2) assembled with body 2, insert 3, and cap 4 comprises head 1A with a relatively large diameter and body 1B with a smaller diameter than head 1A. Body 2 has body body 2b that forms the outer shell of body 1B and body head 2a that forms the outer shell below head 1A. Insert 3 comprises insert head 3a and insert body 3b, and includes a recess 3c recessed upward from the bottom surface of insert body 3b. The cap 4 has a disk portion 4a and a peripheral side portion 4b extending obliquely downward and radially inward from the radially outer end of the disk portion 4a. The button 1 is assembled by crimping the peripheral side portion 4b of the cap 4 from the outside onto the body head 2a of the body 2 that houses the insert 3.

[0003] 1 and 2 includes a disk-shaped base 11 and, for example, two pins 12 extending from the base 11. The diameter of the base 11 is slightly larger than the diameter of the body 1B of the button 1. The two pins 12 of the fixing member penetrate upward through the material f, and then further penetrate the bottom plate of the body 2 of the button 1, and are plastically deformed within the recess 3c of the insert 3, thereby attaching the button 1 to the material f.

[0004] Buttons attached to fabric such as clothing may be removed from the fabric to replace the buttons or recycle the clothing or buttons. Examples of button removal machines used in this case are disclosed in Japanese Utility Model Publication No. 55-87326 (Patent Document 1), Japanese Utility Model Publication No. 64-20209 (Patent Document 2), Japanese Utility Model Publication No. 2-32653 (Patent Document 3), and Chinese Utility Model No. 210551789 (Patent Document 4), etc.

[0005] After a button made up of multiple parts is removed from a fabric using the button removal machine described in the above patent document, there are cases where the button needs to be further disassembled for recycling, etc. The present inventors have focused on this point and arrived at the present invention. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Utility Model Application Publication No. 55-87326 [Patent Document 2] Japanese Utility Model Application Publication No. 64-20209 [Patent Document 3] Publication number 2-32653 [Patent Document 4] Chinese Utility Model No. 210551789 Summary of the Invention [Problem to be solved by the invention]

[0007] An object of the present invention is to provide a button removal tool that can be disassembled into multiple parts when removing a button attached to fabric. [Means for solving the problem]

[0008] According to one aspect of the present invention, there is provided a button removal jig for removing from fabric a button consisting of multiple parts that is attached to the fabric by a fixing member, the button removal jig comprising: a base; a press receiving portion that is arranged above the base and that receives a press and descends from an initial position; a separation plate that is arranged below the base and rises and descends together with the press receiving portion; and a deformation applying portion that extends downward from the press receiving portion and deforms the button, wherein the base includes a first button placement portion for placing the button, and the separation plate includes a second button placement portion that is provided at a position corresponding to the first button placement portion.

[0009] The button removal jig (jig) of the present invention is used as follows: First, a button attached to the fabric by the fixing member is placed in the first button placement portion of the base and the second button placement portion of the separator plate. At this time, the second button placement portion of the separator plate, which is in its initial position, overlaps the first button placement portion of the base. The button-side surface of the fabric is placed facing up, with the other surface (bottom) of the fabric aligned with the bottom surface of the separator plate. The base of the fixing member is then placed on the other surface of the fabric. Next, a downward press is applied to the press support portion using a press machine or the like. This causes the press support portion to descend from its initial position, and the separator plate also descends in conjunction with this. As a result, the second button placement portion of the separator plate moves downward away from the first button placement portion of the base, which is vertically immobile. This causes the separator plate to press the fabric downward and pull the fixing member downward, causing the button to catch on the first button placement portion of the base. This causes the fixing member to separate from the button, and the button is removed from the fabric. At the same time, the deformation applying part also descends together with the press receiving part, and the deformation applying part strikes the button arranged in the first button arrangement part of the base, deforming the button, thereby disassembling the button into multiple parts.

[0010] The buttons and fastening members to be removed from fabric by the button removal jig according to the present invention are shown in Figures 1, 2, 14, and 15, but these are merely examples and are not intended to be limiting. The base, press receiving portion, separating plate, deformation applying portion, etc. of the jig can be made from metal, resin, etc. that have a predetermined strength.

[0011] In one embodiment of the present invention, the first button arrangement portion includes a wide portion having a spacing larger than the diameter of the head of the button and a narrow portion having a spacing smaller than the diameter of the head and larger than the diameter of the body of the button. When the fixing member is pulled downward by the separation plate, the head of the button arranged in the first button arrangement portion of the base is caught between the wide portion and the narrow portion (step portion) of the first button arrangement portion, preventing downward displacement. This causes the fixing member to be pulled downward away from the button and separate from the button.

[0012] In one embodiment of the present invention, the second button arrangement portion includes a second narrow portion having a gap smaller than the diameter of the head of the button, larger than the diameter of the body of the button, and smaller than the diameter of the base of the fixing member. When the separation plate descends, the left and right edges of the separation plate that define the second narrow portion catch on the base of the fixing member via the fabric, and function to press down the base.

[0013] In one embodiment of the present invention, the base includes a base body and a button arrangement member replaceably attached to the base body, the first button arrangement portion being formed in the button arrangement member. This allows the jig to be compatible with multiple types of buttons by preparing multiple types of button arrangement members with different dimensions of the first button arrangement portion and selecting and attaching an appropriate button arrangement member to the base body depending on the dimensions of the button to be removed from the fabric.

[0014] In one embodiment of the present invention, the press bearing portion and the separation plate are connected by a plurality of connecting bars, the base has through holes for passing the connecting bars, and springs are wound around the connecting bars between the base and the press bearing portion. This configuration will be described later with reference to Figure 3 etc.

[0015] According to another aspect of the present invention, there is provided a button removal jig for removing buttons attached to fabric with fastening members from the fabric, the button removal jig comprising: a base; a press receiving section disposed above the base and descending from an initial position when pressed; and a separation plate disposed below the base and ascending and descending together with the press receiving section, the base including a first button placement section for placing the button, and the separation plate including a second button placement section provided at a position corresponding to the first button placement section. This jig differs from the above-described jigs in that it does not include a deformation applying section. Because this jig does not include a deformation applying section, it does not deform or disassemble the button, but only separates the fastening member from the button using the separation plate. [Effects of the Invention]

[0016] In the present invention, buttons attached to the fabric by fixing members are placed in the first button placement section of the base and the second button placement section of the separation plate, and by applying pressure to the press receiving section to lower it, the separation plate is lowered, thereby separating the fixing members from the buttons and deforming the buttons using the deformation applying section, allowing them to be disassembled into parts.

DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to such embodiments and can be modified within the scope of the claims. FIG. 3 is a perspective view of a button removal jig (hereinafter also simply referred to as "jig") 100 according to a first embodiment of the present invention. The jig 100 includes a base 110, a first plate 120 serving as a press receiving portion disposed above the base 110, a second plate 130 serving as a separation plate disposed below the base 110, a deformation applying portion 140 extending downward from the first plate 120, a first button arrangement portion 150 provided on the base 110, and a second button arrangement portion 160 provided on the second plate 130. The base 110 is supported by a stand 117. The base 110, the first plate 120, and the second plate 130 are arranged substantially horizontally. In FIG. 3, the jig 100 is in an initial state in which the first plate 120 is not pressed, and the first plate 120 and the second plate 130 are in their uppermost initial positions.

[0019] The first plate 120 and the second plate 130 are connected in parallel with each other at a predetermined vertical interval by multiple connecting bars 129. In this example, there are three connecting bars 129, but there may be four or more. The base 110 is provided with through-holes 119 through which each connecting bar 129 passes. A coil-shaped compression spring 128 is wound around each connecting bar 129 between the base 110 and the first plate 120. In the initial state, the compression spring 128 lifts and supports the first plate 120 to an initial position relative to the base 110. When the first plate 120 is in the initial position, the second plate 130 is also in the uppermost initial position in contact with the base 110. At this time, the second plate 130 overlaps the base 110. The first plate 120 descends from the initial position when its upper surface 121 is pressed by a press machine 200 (described later) or the like. At this time, the first plate 120 compresses the compression spring 128 between it and the base 110. The through-hole 119 of the base 110 guides the connecting bar 129 in the vertical direction, allowing the first plate 120 to rise and fall while maintaining a horizontal position. The second plate 130 rises and falls together with the first plate 120. The gap between the first plate 120 and the second plate 130 is always constant, including when rising and falling. The base 110 is immovable in the vertical direction and is maintained at the same height.

[0020] FIG. 4 is a perspective view showing the jig 100 set on the press machine 200. The press machine 200 is a device for applying a pressure of at least a certain amount to the first plate 120 of the jig 100. A commercially available hand press or the like can be used as the press machine 200, but the press machine 200 is not limited to this. The press machine 200 is a known device and will not be described in detail. The press machine 200 includes a table 201, a main body 202 that extends in a curved shape from the table 201, a core rod 203 provided at the end of the main body 202 opposite the table 201, and a lever 204 for lowering the core rod 203 from its initial position. A spring (not shown) is wound around the core rod 203. The jig 100 is placed on the table 201 of the press machine 200. When an operator presses down on the lever 204, the core rod 203 descends, allowing the first plate 120 of the jig 100 to be pressed down. When the lever 204 is released from being pressed down, the core rod 203 returns to its initial position above due to the force of the spring.

[0021] The first plate 120 has a plate shape with a portion of a circle removed along a straight line shorter than the diameter, and is larger than a semicircle. The first plate 120 includes an upper surface 121 and linear side surfaces 122. In this specification, the linear side surfaces 122 of the first plate 120 are defined as the front surface of the jig 100. A reinforcing member 123 is provided on the outer portion of the upper surface 121 of the first plate 120 that extends along the arc. The base 110 and the second plate 130 have approximately the same outer shape as the first plate 120 and include linear side surfaces 111 and 131, respectively, which form the front surface of the jig 100. The second plate 130 has a smaller thickness in the up-down direction than the base 110 and the first plate 120. The second plate 130 has a flat lower surface 132. The second plate 130 also includes a central thin portion 133 and an arc-shaped thick portion 134 outside the thin portion 133. The upper surface of the second plate 130 is higher at the thick portion 134 than at the thin portion 133. The lower end of the connecting bar 129 is connected to the thick portion 134 of the second plate 130. The base 110 includes an arc-shaped recess 112 recessed upward from its lower surface to receive the thick portion 134 of the second plate 130 in its initial position.

[0022] The base 110 includes a first button arrangement portion 150, and the second plate 130 includes a second button arrangement portion 160. Below, the buttons and fastening members that the jig 100 targets for removal from fabric will be described using the button 1 and fastening member 10 shown in FIGS. 1 and 2 as examples. However, other buttons and fastening members, including buttons 1C and 1D and fastening members 10A and 10B, which will be described later, can also be targeted. FIG. 5 is a front view of the base 110 cut away to show the first button arrangement portion 150 and the second button arrangement portion 160. The first button arrangement portion 150 is cut out in a roughly semi-elliptical or inverted U-shape from the linear side surface 111 of the base 110 at the midpoint between the left and right sides (the left and right sides are based on the paper surface of FIGS. 5, 6, etc.; the same applies below) to the rear (referring to the front to the back side in the paper surface of FIGS. 5, 6, etc.; the same applies below). The first button arrangement portion 150 penetrates the base 110 from top to bottom. The first button arrangement portion 150 includes a wide portion 151 for arranging the head 1A of the button 1, and a first narrow portion 152 provided below the wide portion 151 for arranging the body 1B of the button 1. A step 153 is formed at the boundary between the wide portion 151 and the first narrow portion 152. The left-right spacing of the wide portion 151 is set to be larger than the diameter of the head 1A of the button 1. The left-right spacing of the first narrow portion 152 is set to be smaller than the diameter of the head 1A of the button 1 and slightly larger than the diameter of the body 1B. The rear of the wide portion 151, the first narrow portion 152, and the step 153 form a semicircular large-diameter side surface, a small-diameter side surface, and a step that are convex rearward, respectively.

[0023] In this embodiment, the base 110 includes a base main body 110A and a button arrangement member 110B that is replaceably attached to the base main body 110A, and the above-described first button arrangement portion 150 is formed in the button arrangement member 110B. By preparing multiple types of first button arrangement portions 150 with different dimensions and selecting an appropriate first button arrangement portion 150 based on the dimensions of the button to be removed from the fabric and attaching it to the base main body 110A, the jig 100 can be made compatible with multiple types of buttons. Referring to FIG. 5, the base main body 110A includes a storage portion 116 for storing the button arrangement member 110B from above. The storage portion 116 is a space that expands the first button arrangement portion 150 and includes an upper large-diameter portion 116a and a lower small-diameter portion 116b. The button arrangement member 110B has an outer shape that roughly matches the housing portion 116, i.e., it includes an upper large diameter portion 115a that matches the large diameter portion 116a and a lower small diameter portion 115b that matches the small diameter portion 116b. The outer shapes of the multiple types of button arrangement members 110B, i.e., the large diameter portion 115a and the small diameter portion 115b, are common to all types. Note that the first button arrangement portion 150 can also be provided directly on the base 110, as will be described later.

[0024] The second button arrangement portion 160 is formed by cutting out the linear side surface 131 of the second plate 130 from the left-right intermediate portion to the rear in a generally semi-elliptical or inverted U-shape, and penetrates the second plate 130 from top to bottom. The second button arrangement portion 160 includes a second narrow portion 161. The left-right spacing of the second narrow portion 161 is set to be smaller than the diameter of the head 1A of the button 1, slightly larger than the diameter of the body 1B, and slightly smaller than the diameter of the base 11 of the fixing member 10. Also, referring to FIG. 5 , the total thickness in the vertical direction of the first narrow portion 152 and the second narrow portion 161, which are initially overlapped vertically, is set to be smaller than the axial length of the body 1B of the button 1. The rear of the second narrow portion 161 forms a semi-circular arc-shaped side surface that convex rearward.

[0025] The base 110 is supported by a stand 117 that curves and extends along the arc-shaped outer periphery of the base 110, with a partial opening on the left side. The front, i.e., the front surface (linear side surface 111) of the base 110 is also open. The fabric f with the attached button 1 is introduced through the front and left openings, and the button 1 is arranged in the first button arrangement portion 150 and the second button arrangement portion 160. A circular bottom plate 118 is provided on the inner bottom of the stand 117. The bottom plate 118 protrudes forward beyond the linear side surface 111 of the base 110. The bottom plate 118 also becomes gradually thinner from the middle to the front in the front-to-rear direction, with the front half of the top surface of the bottom plate 118 sloping toward the front end. This allows the body 2, insert 3, and cap 4, which are components of the button 1, to be easily ejected forward when the button 1 is disassembled into these components as described below.

[0026] The deformation applying portion 140 is a cylindrical member extending downward from the center of the arc-shaped outer periphery of the first plate 120. In this embodiment, the lower end of the deformation applying portion 140 is approximately hemispherical. The axis of the deformation applying portion 140 is concentric with the left-right midpoint of the first button arrangement portion 150 and the second button arrangement portion 160 and the center of the rear arc-shaped side surface. As a result, when the first plate 120 descends, the deformation applying portion 140 abuts against the center of the caps 4 of the buttons 1 arranged on the first button arrangement portion 150 and the second button arrangement portion 160.

[0027] 6 is a front view showing the jig 100 in an initial state in which the button 1 and fixing member 10 attached to the fabric f are placed in the first button arrangement portion 150 and the second button arrangement portion 160. The fabric f is introduced through the front and left openings of the stand 117 with the button 1 side facing upward and the fixing member 10 side facing downward. The head 1A of the button 1 is placed in the wide portion 151 of the first button arrangement portion 150, and the body 1B is placed in the first narrow portion 152 of the first button arrangement portion 150 and the second narrow portion 161 of the second button arrangement portion 160. At this time, the button 1 is pushed all the way to the rear ends of the first button arrangement portion 150 and the second button arrangement portion 160. The fabric f is also placed so as to fit along the underside of the second plate 130. 6, when the operator presses down the lever 204 of the press machine 200, the core rod 203 descends, and a press is applied from above to the first plate 120 of the jig 100, pushing down the first plate 120. Accordingly, the second plate 130 also descends, and each compression spring 128 is compressed between the descending first plate 120 and the stationary base 110.

[0028] Figure 7 is a front view showing the jig 100 in a state in which the second plate 130 and the deformation applying unit 140 have been lowered from the state shown in Figure 6 to their lowest operating positions. Figure 8 is an enlarged view of the area C enclosed by the dashed line in Figure 7. In the change of the jig 100 from Figure 6 to Figures 7 and 8, as will be explained below, the fixing member 10 is pulled downward from the button 1 by the second plate 130, and almost simultaneously, the button 1 is deformed by the deformation applying unit 140 and disassembled into the body 2, insert 3, and cap 4. When the second plate 130 descends together with the pressed first plate 120, the fabric f is also pressed downward by the second plate 130, and the base 11 of the fixing member 10 on the underside of the fabric f is pulled downward by the second plate 130. At this time, because the left-right spacing of the second narrow portion 161 of the second button arrangement portion 160 on the second plate 130 is smaller than the diameter of the base 11 of the fixing member 10, the left and right edges of the second plate 130 that define the second narrow portion 161 catch on the base 11 via the fabric f, functioning to press down on the base 11. Meanwhile, the button 1 arranged in the first button arrangement portion 150 on the stationary base 110 is also pulled downward by the fixing member 10, which is being pulled downward. However, until just before the descending deformation imparting portion 140 contacts the button 1, the head 1A arranged in the wide portion 151 catches on the step 153, preventing the button 1 from displacing downward. This causes the fixing member 10 to be pulled downward away from the button 1 and separate from it. At this time, the pin 12 of the fixing member 10, which was connected to the button 1 in a curved shape, deforms linearly and disengages from the button 1.

[0029] At approximately the same time that the fixing member 10 is separated from the button 1, the hemispherical lower end of the deformation applying portion 140, which descends together with the first plate 120, strikes the center of the cap 4 of the button 1 arranged in the first button arrangement portion 150 of the base 110. This pushes the center of the cap 4 downward, but the radially outer portion of the cap 4 catches on the step portion 153 of the first button arrangement portion 150, deforming the cap 4 so that its center enters the first narrow portion 152. This releases the connection between the cap 4 and the body 2, causing the body 2 and the insert 3 to fall from the first button arrangement portion 150. The body 2 and the insert 3 are ejected forward from above the bottom plate 118. Thereafter, when the lever 204 of the press 200 is released from being pressed down, the core rod 203 returns to its initial position, and the first plate 120 of the jig 100 returns to its initial position due to the decompression of the compression spring 128. At the same time, the second plate 130 also returns to its initial position.

[0030] FIG. 9 is a perspective view schematically illustrating a second embodiment of a button removal jig according to the present invention. The jig 101 shown in FIG. 9 differs from the jig 100 of the first embodiment mainly in that the base 110C is not divided into a base main body and a button arrangement member. In this case, the first button arrangement section 150C is provided directly on the base 110C. Since the configuration other than the base 110C is substantially the same as that of the jig 100, the same reference numerals are used and their description is omitted. Note that FIGS. 9 and 10 omit the recess 112 of the base 110, the reinforcing member 123 of the first plate 120, the thin-walled portion 133 of the second plate 130, the wide portion 151 and the first narrow portion 152 of the first button arrangement section 150, the left opening of the base 117, the bottom plate 118, and the like.

[0031] FIG. 10 is a perspective view schematically illustrating a third embodiment of a button removal jig according to the present invention. The jig 102 shown in FIG. 10 differs from the jig 100 of the first embodiment in that, like the jig 101 of FIG. 9, the base 110C is not divided into a base main body and a button arrangement member, and the jig 102 does not include a deformation imparting unit. Although not shown, the base 110C of the jig 102 may be divided into a base main body and a button arrangement member, like the jig 100. In other words, the third embodiment may be a jig 100 without the deformation imparting unit 140. The jig 102 does not deform or disassemble the button 1 using the deformation imparting unit; it only separates the fixing member 10 from the button 1 using the second plate 130. Therefore, the button to be removed from the fabric by the jig 102 is not limited to a button 1, such as a button 1, which is made up of multiple components, but may also be a button made up of a single component. The separation of the fixing member 10 using the jig 102 is extremely easy, as it only requires placing the button 1 attached to the fabric f in the first button placement section 150C and the second button placement section 160 and pressing down the lever 204 of the press machine 200.

[0032] The deformation applying portion 140 in the jigs 100 and 101 described above has a hemispherical lower end, but this is not limited to this. Fig. 11 is a perspective view showing a modified deformation applying portion. The deformation applying portion 141 shown in Fig. 11 has a flat or slightly downwardly curved lower end surface 141a, a tapered portion 141b whose outer diameter gradually decreases toward the lower end surface 141a, and four equally spaced recesses 141c provided around the tapered portion 141b. Similar to the deformation applying portion 140, this deformation applying portion 141 can also deform and disassemble the button 1.

[0033] FIG. 12 is a perspective view showing another modified example of the deformation applying unit. The deformation applying unit 142 shown in FIG. 12 includes a cylindrical base 142a and a shaft 142b extending concentrically downward from the base 142a. The shaft 142b is cylindrical and has a smaller diameter than the base 142a. FIG. 13 is a front view showing the deformation applying unit 142 lowered to just before its lowest position. The deformation applying unit 142 is provided on the first plate 120 of the jig 100 in place of the deformation applying unit 140. The first plate 120, the second plate 130, etc. are omitted in FIG. 13. A button 1D is arranged in the first button arrangement portion 150 of the base 110 (and the second button arrangement portion 160 of the second plate 130). The button 1D is shown in cross section in FIG. 15 and consists of two parts: a body 2A and a cap 4A. The body 2A includes a pin receiving portion 2B bent upward from its bottom. The center of the cap 4A is open as an opening 4C. The button 1D is fixed to the fabric f by a fixing member 10B. The fixing member 10B includes one pin 12B, which penetrates the fabric f, passes through the pin receiving portion 2B of the button 1D, and is then crimped.

[0034] At the time shown in Figure 13, fixing member 10B (see Figure 15) has been separated from button 1D by second plate 130, and shaft 142b of deformation imparting part 142 has entered the interior of button 1D through open part 4C. Shaft 142b then descends further, pressing body 2A downward through pin receiving part 2B. At this time, body 2A deforms from the portion caught on step 153, and separates from cap 4A. In this way, button 1D can be disassembled by deformation imparting part 142.

[0035] FIG. 14 is a partial cross-sectional view showing an exploded view of another example of a button made up of multiple parts, showing the base material f and the fastening member 10A. The button 1C shown in FIG. 14 is made up of two parts: a body 3A and a cap 4. The cap 4 is substantially the same as the cap 4 of button 1, and includes a disk portion 4a and a peripheral portion 4b. The body 3A has a body head 3Aa and a body trunk 3Ab. The body 3A also includes a pin receiving portion 3Ac, which is a cavity extending upward from the bottom surface. The button 1C is assembled by crimping the peripheral portion 4b of the cap 4 to the body head 3Aa of the body 3A. Like button 1, button 1C also includes a head 1A and a trunk 1B with a smaller diameter than the head 1A. For convenience, the head and trunk portions of buttons 1C and 1D (see FIG. 15) are designated 1A and 1B, respectively. Fixing member 10A has base 11A and one pin 12A extending from base 11A. A thread groove is machined into the tip of pin 12A. As with button 1, button 1C can also be separated from fabric f and fixing member 10A using jigs 100, 101, and 102, and button 1C can also be disassembled using jigs 100 and 101.

[0036] FIG. 15 is a partial cross-sectional view showing yet another example of a button made up of multiple parts, showing both the fabric f and the fastening member 10B. The button 1D shown in FIG. 15 consists of two parts: a body 2A and a cap 4A. As described above, the body 2A includes a pin receiving portion 2B bent upward from its bottom. The body 2A has substantially the same shape as the body 2 of the button 1, except for the pin receiving portion 2B. The cap 4A opens in the center as an opening 4C. The cap 4A has substantially the same shape as the cap 4 of the button 1, except for the opening 4C. The button 1D is fixed to the fabric f by the fastening member 10B. The fastening member 10B includes one pin 12B. After penetrating the fabric f, the pin 12B is passed through the pin receiving portion 2B of the button 1D and then crimped, thereby fixing the button 1D to the fabric f. As with button 1, button 1D can also be separated from fabric f and fixing member 10B using jigs 100, 101, 102, and button 1D can also be disassembled using jigs 100, 101, particularly jigs 100, 101 provided with deformation imparting portion 142.
