[0035] [First Implementation Method]

[0036] The first embodiment of the present invention will now be described with reference to the accompanying drawings.

[0037] exist Figures 1 to 4 In this embodiment, the zipper pull 1 is used in an adjustable zipper for adjusting the size of specific parts of an item, such as the abdominal circumference or sleeve circumference of clothing. The zipper pull 1 includes: a main body 10, which is configured with a guide groove 11 for inserting along a pair of zipper teeth (not shown) in a manner that can engage and disengage; a pull tab 50, which can operate the main body 10 in a sliding direction; and a locking pin 60, which can engage with the zipper teeth in the guide groove 11.

[0038] In the following description, the sliding direction of the slider 1 is taken as the X-axis direction, the direction orthogonal to the X-axis direction is taken as the Y-axis direction (left-right direction, width direction), and the direction orthogonal to both the X-axis and Y-axis directions is taken as the Z-axis direction (up-down direction, thickness direction).

[0039] The main body 10 consists of a first main body component 20 made of metal using a mold for planar division and a second main body component 30 made using a mold for bending division.

[0040] The pull tab 50 has a plate-shaped pull tab body 51 and a shaft portion 52 formed at the end of the pull tab body 51. The shaft portion 52 is configured as a cam shape that allows the locking pin 60 to elastically deform upward during its rotation.

[0041] The locking pin 60 is composed of an elastic piece 63 that has an engaging end 61 and an mounting end 62 and is bent into shape.

[0042] The first main body component 20 includes: an upper plate portion 21; a column portion 22 continuous with the upper plate portion 21; and a first engaging portion 23 formed in the column portion 22. A connecting portion 211 is formed in the upper plate portion 21, which is rotatably connected to the shaft portion 52 of the pull tab 50. A pin mounting portion 24 for arranging the locking pin 60 is formed in both the upper plate portion 21 and the column portion 22. The upper surface 215 of the upper plate portion 21 is formed as a flat surface, except for the portion where the connecting portion 211 and the pin mounting portion 24 are mounted.

[0043] like Figure 2 As shown, the connecting portion 211 has a pair of connecting pieces 212 protruding upward from the upper plate portion 21 and facing each other in the X-axis direction, with a connecting groove 213 formed between the pair of connecting pieces 212. The pair of connecting pieces 212 are formed on the left and right sides respectively relative to the pin assembly portion 24. By causing the shaft portion 52 of the pull tab 50 to enter from above relative to the connecting groove 213 and pressing the top ends of the pair of connecting pieces 212 together, they are brought closer to each other, thereby making the connecting portion 211... Figure 1 It is connected to pull tab 50 as shown.

[0044] In this embodiment, the pin assembly portion 24 is formed in the shape of a groove along the X-axis and has a pin insertion hole portion 241 for inserting the engaging end 61 of the locking pin 60 and a pin mounting portion 242 for mounting the mounting end 62. The pin insertion hole portion 241 is formed to pass vertically through the upper plate portion 21 so that the engaging end 61 can move in and out relative to the guide groove 11. The pin mounting portion 242 is formed to pass vertically through the upper plate portion 21 and the post portion 22 so that the mounting end 62 of the locking pin 60 can be engaged by pushing against the front and rear walls.

[0045] Here, the locking pin 60, mounted on the pin assembly 24, abuts against the shaft portion 52 of the pull tab 50 from above. The engaging end 61 is normally configured to protrude into the guide groove 11 and engage with the chain teeth, restricting the sliding movement of the pull head 1 in the X-axis direction. Furthermore, when the locking pin 60 elastically deforms upwards due to the shaft portion 52 during rotation of the operated pull tab 50, the engaging end 61 is configured to be pulled out of the guide groove 11, releasing the engagement with the chain teeth.

[0046] The first engaging portion 23 has an engaging main body portion 231 extending from the lower part of the post portion 22 in the front and rear directions in the X-axis direction, and engaging step portions 232 and 233 descending downward on the front and rear sides of the engaging main body portion 231. Figure 4 As shown, the engaging step portion 232 extends from the lower surface of the engaging main body piece portion 231 to one of the front and rear sides, and the engaging step portion 233 extends from the lower surface of the engaging main body piece portion 231 to the other of the front and rear sides.

[0047] The dimension L1 of the engaging main body plate 231 in the X-axis direction is smaller than the dimension L2 of the groove 35 formed on the lower plate 31 (described later) in the X-axis direction. The dimension L3 of the upper surface 232A of the engaging step 232 in the X-axis direction is larger than the dimension L4 of the upper surface 233A of the engaging step 233 in the X-axis direction. The combined dimension of L1 and L4 is equal to or less than the dimension L2. The combined dimension of L1, L3, and L4 is larger than the dimension L2.

[0048] like Figure 2 As shown, the second main body component 30 includes: a lower plate portion 31; left and right guide sides 32, which are formed on the front and rear sides of the lower plate portion 31 in the X-axis direction relative to the column portion 22, respectively; a cord-like mounting portion 33 provided on one of the front and rear ends of the lower plate portion 31; and a second engaging portion 34 formed to engage with the first engaging portion 23. A groove portion 35 extending in the X-axis direction between the left and right guide sides 32 is formed in the lower plate portion 31. The lower surface 310 of the lower plate portion 31 is preferably a relatively flat surface without protrusions or the like.

[0049] The cord / strap mounting section 33 is formed by a through hole in the Z-axis direction, through which cords / straps (not shown) pass and are mounted. Here, the cord / strap is connected to a specific part of an item such as clothing, and the specific part is tightened or loosened by the sliding movement of the pull head 1.

[0050] The left and right guide sides 321 on one of the front and rear sides, which are opposite each other in the Y-axis direction, are inclined to the left and right outwards relative to the X-axis direction as they move from one of the front and rear sides towards the other side of the front and rear sides. Therefore, the spacing between the left and right guide sides 321 on one of the front and rear sides gradually increases as they move from one of the front and rear sides towards the other side of the front and rear sides.

[0051] The left and right guide sides 321 on the other side of the front and rear sides, which are opposite each other in the Y-axis direction, are inclined relative to the X-axis direction in such a way that they move outward to the left and right as they move from the other side of the front and rear sides towards one of the front and rear sides. Therefore, the spacing between the left and right guide sides 321 on the other side of the front and rear sides gradually increases as they move from the other side of the front and rear sides towards one of the front and rear sides.

[0052] The second engaging portion 34 has engaging holes 341 and 342 formed on the lower plate portion 31. The engaging hole 341 on one of the front and rear sides is connected to the front or rear end of the groove portion 35 in the X-axis direction, allowing the engaging step portion 232 on one of the front or rear sides to be inserted. The engaging hole 342 on the other of the front and rear sides is connected to the other front or rear end of the groove portion 35 in the X-axis direction, allowing the engaging step portion 233 on the other of the front or rear sides to be inserted. Furthermore, clamping grooves 313 are formed on the lower plate portion 31 on both the left and right sides of the engaging hole 341.

[0053] The engagement dimension of the engaging hole portion 341 and the engaging step portion 232 in the X-axis direction, and in this embodiment, the engagement dimension of the lower surface 311 of the portion forming the engaging hole portion 341 in the lower plate portion 31 and the upper surface 232A of the engaging step portion 232 in the X-axis direction, is greater than the engagement dimension of the engaging hole portion 342 and the engaging step portion 233 in the X-axis direction, and in this embodiment, the engagement dimension of the lower surface 312 of the portion forming the engaging hole portion 342 in the lower plate portion 31 and the upper surface 233A of the engaging step portion 233 in the X-axis direction.

[0054] The following describes the assembly steps for the zipper puller 1.

[0055] First, the pull tab 50 and the locking pin 60 are installed on the connecting part 211 and the pin assembly part 24 of the first main body component 20, as follows: Figure 3As shown, the engaging step portion 232 of the first main body component 20 is inserted into the engaging hole portion 341. Next, the engaging step portion 233 of the first main body component 20 is positioned into the engaging hole portion 342, and the engaging main body piece portion 231 is positioned into the groove portion 35 of the lower plate portion 31.

[0056] Next, the first main body component 20 is slidably moved relative to the second main body component 30 to the other side of its front and rear sides (the engaging hole 342 side) to engage the engaging step portion 233 into the engaging hole portion 342. At this time, as Figure 4 As shown, the engaging step portions 232 and 233 are engaged with the engaging hole portions 341 and 342 respectively. The upper surface 232A of the engaging step portion 232 abuts against the lower surface 311 of the lower plate portion 31, and the upper surface 233A of the engaging step portion 233 abuts against the lower surface 312 of the lower plate portion 31.

[0057] Finally, tools are inserted into the left and right clamping grooves 313 of the second main body 30 and clamped, thereby preventing the engaging step portion 232 from being pulled out of the engaging hole portion 341.

[0058] Since the main body 10 is constructed by directly engaging the first main body component 20 and the second main body component 30, the zipper pull 1 can be easily assembled.

[0059] A pair of zipper teeth are inserted into the guide groove 11 of the assembled zipper head 1. During the sliding movement of the zipper head 1, the pair of teeth are separated left and right by the post 22, and then guided and engaged by the left and right guide sides 32. Therefore, the part of the teeth not containing the zipper head 1 is always in an engaged state.

[0060] According to the first embodiment of the zipper pull 1, since the first engaging part 23 and the second engaging part 34 directly engage without using other components such as the pull tab 50, a single zipper pull 1 can be formed. For example, compared with the case where two zipper pull components are connected by a connecting member to form a zipper pull, since only a single zipper pull 1 is exposed to the outside, the appearance is good. In addition, since there is no need for connecting members, the zipper pull 1 can be miniaturized.

[0061] Furthermore, since the first engaging portion 23 and the second engaging portion 34 directly engage as described above, the first main body component 20 and the second main body component 30 can be easily aligned, and the installation of other components can be omitted, reducing the effort required to connect the first main body component 20 and the second main body component 30. Therefore, the productivity of the zipper pull 1 used in adjustable zippers can be improved. In addition, since the pull tab 50 and the locking pin 60 can be installed relative to the first main body component 20 itself before connecting the first main body component 20 and the second main body component 30, the productivity of the zipper pull 1 can be improved.

[0062] Furthermore, since the first main body component 20 has an upper plate portion 21, a column portion 22, and a first engaging portion 23, while the second main body component 30 has a lower plate portion 31, left and right guide portions 32 on the front and rear sides, and a second engaging portion 34, conventional molds such as planar division can be used in the manufacture of the first main body component 20, and conventional molds such as bending division can be used in the manufacture of the second main body component 30. For example, compared with the case of using a special mold for special division, the mold is easier to manufacture and the durability of the mold can be improved.

[0063] [Second Implementation]

[0064] The second embodiment of the present invention will now be described with reference to the accompanying drawings.

[0065] exist Figures 5 to 7 In the second embodiment, the zipper pull 1B is used in an adjustable zipper in the same manner as described above, and includes a body 10B, a pull tab 50, and a locking pin 60. The body 10B is configured with guide grooves 11 for inserting along a pair of zipper teeth in a manner that allows them to engage and disengage. The body 10B is composed of a first body component 20B made of metal using a planar dividing mold, and a second body component 30B made using a bending dividing mold.

[0066] The first main body component 20B includes: an upper plate portion 21B; a column portion 22B continuous with the upper plate portion 21B; and a first engaging portion 23B formed in the column portion 22B. A connecting portion 211, as described above, is formed in the upper plate portion 21B, and a pull tab 50 is rotatably connected to the connecting portion 211. A pin mounting portion 24, as described above, is formed on the upper plate portion 21B and the column portion 22B, and a locking pin 60 is mounted on the pin mounting portion 24. The upper surface 215 of the upper plate portion 21B, except for the portion where the connecting portion 211 and the pin mounting portion 24 are mounted, is formed as a flat surface.

[0067] The first engaging portion 23B has a plate-shaped engaging main body plate portion 231B that is continuous with the lower part of the post portion 22B, and engaging holes 234B formed on the left and right sides of the engaging main body plate portion 231B in the X-axis direction. A cord-like mounting portion 33 is formed on one end of one of the front and rear sides of the engaging main body plate portion 231B. Side wall portions 235B are formed on the engaging main body plate portion 231B in the left and right directions along the X-axis direction. Figure 7 The image shows the front and rear engaging holes 234B on one side. Although not shown, the other side also has front and rear engaging holes 234B. The hole shape of each engaging hole 234B is formed to complement the shape of each guide side 32B described later.

[0068] The second main body component 30B includes: a lower plate portion 31B; left and right guide sides 32B, which are formed on the front and rear sides of the lower plate portion 31B in the X-axis direction relative to the column portion 22B, respectively; and a second engaging portion 34B formed to engage with the first engaging portion 23B. The lower surface 310 of the lower plate portion 31B is preferably a relatively flat surface without protrusions or the like. Since the left and right guide sides 32B on the front and rear sides are configured in substantially the same way as the aforementioned left and right guide sides 32, detailed description is omitted.

[0069] The second engaging portion 34B has engaging claw portions 345B respectively formed on each guide side portion 32B. The left and right engaging claw portions 345B formed on the left and right guide side portions 32B on one of the front and rear sides protrude along the X-axis direction toward the left and right guide side portions 32B on the other of the front and rear sides. The left and right engaging claw portions 345B formed on the left and right guide side portions 32B on the other of the front and rear sides protrude along the X-axis direction toward the left and right guide side portions 32B on one of the front and rear sides.

[0070] The following describes the assembly steps for the slider 1B.

[0071] First, the pull tab 50 and locking pin 60 are installed onto the first main body component 20B, which is attached to the connecting part 211 and the pin assembly part 24. Next, the left and right guide sides 32B of the second main body component 30B are inserted from below relative to the left and right engaging holes 234B on the front and rear sides of the first main body component 20B. Then, the left and right engaging claws 345B on the front and rear sides are engaged with the engaging main body plate 231B, resulting in a mating state between the engaging main body plate 231B and the lower plate 31B.

[0072] Since the main body 10B is constructed by directly engaging the first main body component 20B with the second main body component 30B, the zipper pull 1B can be easily assembled.

[0073] A pair of zipper teeth are inserted into the guide groove 11 of the assembled zipper head 1B. During the sliding movement of the zipper head 1B, the pair of teeth are separated left and right by the post 22B, and after separation, they are guided and engaged by the left and right guide sides 32B. Therefore, the portion of the teeth not containing the zipper head 1B is always in an engaged state.

[0074] According to the second embodiment of the pull head 1B, since the first main body component 20B and the second main body component 30B directly engage, the effort required to connect them can be reduced. In addition, conventional molds such as planar division and bending division can be used in the manufacturing of the first main body component 20B and the second main body component 30B.

[0075] Therefore, the pull head 1B of the second embodiment can perform the aforementioned effects.

[0076] [Third Implementation Method]

[0077] The third embodiment of the present invention will now be described with reference to the accompanying drawings.

[0078] exist Figures 8 to 10 In the third embodiment, the zipper pull 1C is used in an adjustable zipper in the same manner as described above, and includes a main body 10C, a pull tab 50, and a locking pin 60. The main body 10C is configured with guide grooves 11 for inserting along a pair of zipper teeth in a manner that allows them to engage and disengage. The main body 10C is composed of a first main body component 20C and a second main body component 30C manufactured using a planar segmentation mold, and has left and right guide sides 32C respectively arranged on the front and rear sides in the X-axis direction relative to the post portion 22C described later.

[0079] The first main body component 20C includes: an upper plate portion 21C and a lower plate portion 25C; a column portion 22C connecting the upper plate portion 21C and the lower plate portion 25C; a cord-like mounting portion 33 formed on the lower plate portion 25C; and a first engaging portion 23C formed on the lower plate portion 25C. The aforementioned connecting portion 211 is formed on the upper plate portion 21C, and the pull tab 50 is rotatably connected to the connecting portion 211. The aforementioned pin mounting portion 24 is formed on the upper plate portion 21C and the column portion 22C, and a locking pin 60 is mounted on the pin mounting portion 24. The upper surface 215 of the upper plate portion 21C is formed as a flat surface, except for the portion where the connecting portion 211 and the pin mounting portion 24 are mounted. The lower surface 310 of the lower plate portion 25C is preferably a relatively flat surface without protrusions or the like.

[0080] The rope-type mounting part 33 is located at one end of the lower plate part 25C in the X-axis direction, either front or rear.

[0081] The first engaging portion 23C is composed of an engaging recess located at the opposite end of the lower plate portion 25C in the X-axis direction.

[0082] One of the left and right guide sides 32C is formed on one of the front and rear sides of the lower plate portion 25C, and is disposed between the column portion 22C and the rope-type mounting portion 33 in the X-axis direction. Since the left and right guide sides 32C are substantially the same as the aforementioned left and right guide sides 32, detailed description is omitted.

[0083] The second main body component 30C has an insertion main body portion 36C that is inserted between the upper plate portion 21C and the lower plate portion 25C in the X-axis direction, and a second engaging portion 34C that is formed to engage with the first engaging portion 23C.

[0084] The insert body 36C has an inner upper plate 37C and an inner lower plate 38C, and an auxiliary column 39C connecting the inner upper plate 37C and the inner lower plate 38C. The inner upper plate 37C is arranged along the upper plate 21C. The inner lower plate 38C is arranged along the lower plate 25C. The auxiliary column 39C is fitted onto the other side of the column 22C in the X-axis direction from the front and rear sides. By fitting the auxiliary column 39C in this way, the second body component 30C can be easily and securely assembled with respect to the first body component 20C.

[0085] like Figure 10 As shown, the second engaging portion 34C is composed of an engaging protrusion provided on the inner lower plate portion 38C, which protrudes downward from the lower surface of the inner lower plate portion 38C.

[0086] The left and right guide sides 32C on the other side of the front and rear sides are respectively formed on the inner lower plate portion 38C. Since the left and right guide sides 32C are configured in a substantially the same way as the aforementioned left and right guide sides 32, detailed description is omitted.

[0087] The following describes the assembly steps for the zipper puller 1C.

[0088] First, the pull tab 50 and locking pin 60 are prepared to be installed on the first main body component 20C, which is attached to the connecting part 211 and the pin assembly part 24. Next, the second main body component 30C is inserted relative to the first main body component 20C from the other side of the front and rear sides in the X-axis direction, and the second engaging part 34C engages with the first engaging part 23C. At this time, the inner upper plate part 37C is arranged along the upper plate part 21C, the inner lower plate part 38C is arranged along the lower plate part 25C, and the auxiliary column part 39C is fitted into the column part 22C. The guide groove 11 is formed by the first main body component 20C and the second main body component 30C.

[0089] Since the main body 10C is constructed by directly engaging the first main body component 20C with the second main body component 30C, the zipper pull 1C can be easily assembled.

[0090] A pair of zipper teeth are inserted into the guide groove 11 of the assembled zipper head 1C. During the sliding movement of the zipper head 1C, the pair of teeth are separated left and right by the post 22C, and then guided and engaged by the left and right guide sides 32C. Therefore, the portion of the teeth not equipped with the zipper head 1C is always in an engaged state.

[0091] According to the third embodiment of the zipper pull 1C, since the first main body component 20C and the second main body component 30C directly engage, a single zipper pull 1C can be formed. For example, compared with the case where two zipper pull components are connected by a connecting component to form a zipper pull, since only a single zipper pull 1C is exposed to the outside, the appearance is good. In addition, since there is no need for connecting components, the zipper pull 1C can be miniaturized.

[0092] In addition, since the first main body component 20C and the second main body component 30C directly engage as described above, the time required for their connection can be reduced.

[0093] Furthermore, since the first main body component 20C has a left and right guide side 32C on one of the front and rear sides in the X-axis direction, and the second main body component 30C has a left and right guide side 32C on the other side in the X-axis direction, conventional molds such as planar division can be used in the manufacturing of the first main body component 20C and the second main body component 30C. For example, compared with the case of using a special mold with special division, the mold is easier to manufacture and the mold durability can be improved.

[0094] Therefore, the pull head 1C of the third embodiment can perform the aforementioned effects.

[0095] [Fourth Implementation Method]

[0096] The fourth embodiment of the present invention will now be described with reference to the accompanying drawings.

[0097] exist Figure 11 and Figure 12 In the fourth embodiment, the pull head 1D is constructed in a manner substantially similar to the pull head 1 of the first embodiment, but the structures of the mounting end 62 of the locking pin 60 and the pin mounting portion 242 of the pin assembly portion 24 are different.

[0098] In this embodiment, the mounting end 62 of the locking pin 60 is not as... Figure 4 As shown, it is formed by bending from the upper plate portion 21 toward the interior of the column portion 22, rather than as... Figure 12 It extends along the X-axis as shown, and its top end bends downward. In addition, the mounting end 62 is inclined downward relative to the X-axis direction as it moves away from the engaging end 61 along the X-axis direction.

[0099] In this embodiment, the pin mounting portion 242 has a clamping portion 243 that clamps the mounting end 62 of the locking pin 60. For example... Figure 11 As shown, the clamping part 243 is composed of clamping plate parts 244 disposed on the left and right sides relative to the mounting end 62.

[0100] In the pull head 1D, the locking pin 60 can be easily installed on the upper plate 21 by pressing the mounting end 62 from the left and right by the clamping part 243 against the locking pin 60 disposed on the pin assembly part 24.

[0101] [Fifth Implementation Method]

[0102] The fifth embodiment of the present invention will now be described with reference to the accompanying drawings.

[0103] exist Figure 13 and Figure 14 In the fifth embodiment, the pull head 1E is constructed in a manner substantially similar to the pull head 1 of the first embodiment, but the structures of the mounting end 62 of the locking pin 60 and the pin mounting portion 242 of the pin assembly portion 24 are different.

[0104] like Figure 14 As shown, in this embodiment, the mounting end 62 of the locking pin 60 folds the elastic piece 63 back to form a cross-section that is approximately U-shaped.

[0105] In this embodiment, the pin mounting portion 242 has a hook portion 245 for hooking the top end of the mounting end 62 of the locking pin 60. For example... Figure 13 As shown, the hook portion 245 is composed of hook plate portions 246 disposed on the left and right sides relative to the mounting end 62. The upper edges of the left and right hook plate portions 246 protrude inward to the left and right, and a downwardly protruding top hook portion 247 is formed on the portion of the upper edge on the engaging end 61 side in the X-axis direction.

[0106] In the zipper pull 1E, by inserting the mounting end 62 of the locking pin 60 between the left and right hook portions 246 and hooking the top end 62 onto the top hook portion 247, the locking pin 60 can be easily mounted on the upper plate portion 21.

[0107] [Sixth Implementation Method]

[0108] The sixth embodiment of the present invention will now be described with reference to the accompanying drawings.

[0109] exist Figure 15 and Figure 16 In the sixth embodiment, the pull head 1F is constructed in a manner substantially the same as the pull head 1 of the first embodiment, but the structure of the mounting end 62 of the locking pin 60 and the pin mounting part 242 of the pin assembly part 24 are different.

[0110] like Figure 16 As shown, in this embodiment, the mounting end 62 of the locking pin 60 extends along the X-axis direction and is inclined downward relative to the X-axis direction as it moves away from the engaging end 61 along the X-axis direction.

[0111] In this embodiment, the pin mounting portion 242 has a pin pressing portion 249 composed of pin pressing pieces 248 disposed on the left and right sides relative to the mounting end 62, and a pin insertion portion 250 formed between the left and right pin pressing pieces 248. The upper edge of the left and right pin pressing pieces 248 is configured as a pin abutment portion 251 protruding inward to the left and right sides.

[0112] In the pull head 1F, by inserting the mounting end 62 of the locking pin 60 into the pin insertion portion 250, the pin abutment portion 251 is pushed from above relative to the mounting end 62, thereby enabling the locking pin 60 to be easily mounted on the upper plate portion 21.

[0113] According to the aforementioned fourth to sixth embodiments of the zipper pulls 1D to 1F, for example, compared to the case where the mounting end 62 of the locking pin 60 is inserted from the upper plate portion 21 into the column portion 22 for installation as in the first embodiment, it is no longer necessary to insert the locking pin 60 into the column portion 22. Therefore, the constraints on the arrangement of the column portion 22C and the connecting portion 211 are reduced, and it is easier to arrange the column portion 22C and the connecting portion 211 at the central position in the X-axis direction of the main body 10C. Therefore, it is possible to improve the operability and appearance design of the zipper pull 1F.

[0114] Furthermore, the pull heads 1D to 1F according to the fourth to sixth embodiments can exert the same effect as those in the first embodiment described above.

[0115] [Variation Example]

It may also be formed at the other end, which is opposite to the end of the first end, or at both ends. Alternatively, it may be formed at one or two edges in the Y-axis direction of the second main body component 30.

[0117] In the second embodiment, a cord-like mounting portion 33 is installed on the first main body component 20B, but it may also be installed on the second main body component 30B instead of the first main body component 20B. Furthermore, in the second embodiment, the cord-like mounting portion 33 is formed at one end of the engaging main plate portion 231B in the first engaging portion 23B of the first main body component 20B, but it may also be formed at the other end opposite to the one-way end, or at both ends. Additionally, it may be formed on one or two edges in the Y-axis direction of the first main body component 20B.

[0118] In the third embodiment, the first engaging portion 23C is formed on the lower plate portion 25C and the second engaging portion 34C is formed on the inner lower plate portion 38C. However, instead of this, or otherwise, the first engaging portion 23C may be formed on the upper plate portion 21C and the second engaging portion 34C may be formed on the inner upper plate portion 37C.

[0119] In the third embodiment, the left and right guide sides 32C on one side of the front and rear sides are formed on the lower plate portion 25C, and the left and right guide sides 32C on the other side of the front and rear sides are formed on the inner lower plate portion 38C.
