As an option, the slider 40 has a pull attachment bracket 48 and a pull 49 attached to the upper blade 41 a via the pull attachment attachment 48. As an option, the slider 40 has a locking claw member 47 operated by a pull 49.

In addition to the first and

second fastener stringers

31 and 32 and the slider 40 described above, the slide fastener 1 is applied to the first tape area existing between the end 11 e of the first fastener tape 11 and the first fastener element 21. It has a first stop 51 attached and a second stop 52 attached to a second tape area existing between the end 12 e of the second fastener tape 12 and the second fastener element 22. The first stop member 51 slightly protrudes rearward of the end 11 e of the first fastener tape 11. Similarly, the second stop member 52 slightly protrudes rearward beyond the end 12 e of the second fastener tape 12. In other cases, the first stop member 51 projects rearward of the end 11 e of the first fastener tape 11 to a degree larger or smaller than the illustrated example. In some cases, the first stop member 51 does not project rearward of the end 11 e of the first fastener tape 11, and the entire first stop member 51 is located forward of the end 11 e of the first fastener tape 11. . Alternatively or additionally, in some cases, the second stop member 52 does not project rearward beyond the end 12 e of the second fastener tape 12, and the entire second stop member 52 is the end of the second fastener tape 12. Located forward of 12e. When the retaining member is made of resin, the retaining member adheres to the tape area.

The first stop member 51 is located between the first base 61 and the first base 61 and the first fastener element 21, and is inserted into the slider 40 through the rear opening 45 of the slider 40. Have. The first insertion portion 71 extends from the first base portion 61 toward the first fastener element 21 along the front-rear direction. The second stop member 52 is located between the second base 62, the second base 62 and the second fastener element 22, and is inserted into the slider 40 through the second slit 46n of the slider 40. Having 72. The second insertion portion 72 extends from the second base 62 toward the second fastener element 22 along the front-rear direction. The second stop member 52 optionally has a third fastener element 23. The third fastener element 23 is connected to the front end of the second insertion portion 72. The third fastener element 23 is disposed adjacent to the second fastener element 22. The third fastener element 23 promotes the ease of movement of the slider 40 when the slider 40 advances with the first insertion portion 71 and the second insertion portion 72 inserted in the slider 40, and / or a fastener It is provided to fill the gap between the element and the stop member.

The first insert 71 is suitably shaped to facilitate the retention of the slider 40 on the first insert 71. When the first insertion portion 71 is inserted into the slider 40, the movement of the slider 40 is restricted by the first insertion portion 71, whereby the positioning of the slider 40 on the first stop member 51 is promoted. In some cases, as is clearly understood from FIG. 7, the first insertion portion 71 may include a first side surface 71i or a first side surface 71i extending straight in the front-rear direction from the first base 61 or an upper stop wall 85a described later. It has a second side surface 71u that gradually inclines to the left as it extends forward. The first side surface 71i and the second side surface 71u correspond to the shape of the inner side surface of the upper flange portion 41b of the slider 40. As a result, when the first insertion portion 71 is completely inserted into the slider 40, the slider 40 is prevented from advancing such that the slider 40 is separated from the first insertion portion 71.

In some cases, the first insertion portion 71 has an upper plate portion 71a and a lower plate portion 71b, and at least a portion of the insertion groove 80 in which the second insertion portion 72 is inserted by the upper plate portion 71a and the lower plate portion 71b. Defined. By allowing the first insertion portion 71 and the second insertion portion 72 to be fitted, separation of the first stop member 51 and the second stop member 52 once combined can be suppressed. As can be understood from the following description, the second insertion portion 72 is moved by moving the slider 40 forward while the second insertion portion 72 enters the slider 40 through the second slit 46 n of the slider 40. It is inserted into the insertion groove 80 between the upper plate portion 71 a and the lower plate portion 71 b of the insertion portion 71. The vertical movement of the second insertion portion 72 is preferably restricted between the upper plate portion 71a and the lower plate portion 71b.

In some cases, as best seen in FIGS. 7 and 8, the upper plate portion 71a of the first insertion portion 71 has an upper plate inclined portion 71m obliquely inclined upward, and the lower plate portion 71b obliquely downward. An inclined lower plate inclined portion 71n is provided, and an inlet of the insertion groove 80 is positioned between the upper plate inclined portion 71m and the lower plate inclined portion 71n. In such a case, when the first insertion portion 71 is inserted into the slider 40, the upward and downward movement of the slider 40 is restricted by the first insertion portion 71, and it is further promoted that the slider 40 stays in the first insertion portion 71. Be done. In some cases, the upper plate inclined portion 71m contacts the inner surface of the upper wing portion 41 (or upper wing plate 41a) of the slider 40. The lower plate inclined portion 71 n contacts the inner surface of the lower wing portion 42 (or lower wing plate 42 a) of the slider 40. In some cases, the upper surface of the front end of the upper plate inclined portion 71m is a downward inclined surface, and wear due to contact with the slider 40 is avoided or suppressed. The distance A between the uppermost point of the upper plate inclined portion 71m of the first insertion portion 71 and the lowermost point of the lower plate inclined portion 71n in the thickness direction and the inner surface of the upper blade 41a of the slider 40 and the inner surface of the lower blade 42a The relationship of the distance B in the thickness direction satisfies A ≧ B.

The first stop member 51 may optionally have an upper stop wall 85a coupled to the upper plate portion 71a of the first insertion portion 71 and a lower stop wall 85b coupled to the lower plate portion 71b of the first insertion portion 71. . In some cases, the vertical height of the lower stop wall 85b is larger than the vertical height of the upper stop wall 85a. In some cases, when the first insertion portion 71 is completely inserted into the slider 40 through the rear opening 45 of the slider 40, the upper stop wall 85a is the upper wing plate 41a in the vertical direction in which the connecting post 43 extends. The lower stop wall 85b has a height not exceeding the lower surface of the lower blade 42a. Thinning of the first stop member 51 is promoted.

The first stop member 51 may optionally have a guide wall 86 coupled to the lower stop wall 85b. The guide wall 86 extends in the front-rear direction, and guides the movement of the slider 40 onto the first insertion portion 71. The first stop member 51 is optionally provided between an upper thin plate portion 87 a provided on the left of the upper plate portion 71 a of the first insertion portion 71 and a lower plate portion 71 b of the first insertion portion 71 and the guide wall 86. It may have a lower thin plate portion 87b provided. The upper thin plate portion 87a and the lower thin plate portion 87b promote adhesion of the first stopper 51 to the first fastener tape 11. The second stop member 52 optionally has upper and

lower stop walls

79a, 79b projecting up and down adjacent to the second insertion portion 72. The upper stop wall 79 a can contact the upper flange portion 41 b of the slider 40. The lower stop wall 79 b can contact the lower flange portion 42 b of the slider 40.

In the present embodiment, the second insertion portion 72 moves toward the second slit 46 n of the slider 40 according to the rotation of at least one of the first and

second bases

61 and 62.

Although not necessarily limited to this, in some cases, the first and

second bases

61, 62 may be stacked and / or united through rotation of at least one of the first and

second bases

61, 62. In response to this rotation, the second insertion portion 72 moves toward the second slit 46n of the slider 40, and the distance between the first and

second bases

61 and 62 decreases. In other words, by sandwiching the first and

second bases

61, 62 between the thumb and forefinger, the second insertion portion 72 moves toward the second slit 46n of the slider 40, and the first and second bases The

interval

61, 62 is reduced. By pinching the first and

second bases

61 and 62 between the thumb and forefinger, the second insertion portion 72 is pivoted, and the time and effort for inserting the second insertion portion 72 into the slider 40 is reduced. That is, facilitation of the operation of the first and

second stoppers

51, 52 required when closing the slide fastener 1 is promoted.

In some cases, as best understood from the additional reference to FIG. 25, the second insert 72 is formed between the second base 62 and the second fastener element 22 in the lower wing 42 (or lower wing 42a). It has an insertion end 73 which extends to have a shape according to the contour. Thereby, the interference between the insertion end 73 and the lower wing 42 is avoided or reduced, and the facilitation of the operation that should result in the movement of the second insertion part 72 toward the second slit 46 n of the slider 40 is promoted. This operation is not necessarily limited to the operation described in the next paragraph.

In some cases, when the second insertion portion 72 takes an initial position in contact with the lower surface of the lower wing portion 42 (see FIG. 26A), the first and

second bases

61 and 62 are placed between the thumb and forefinger. When pinched, the second insertion portion 72 passes the right side of the lower wing portion 42 (see FIG. 26B), and can then enter the slider 40 successfully through the second slit 46 n (FIG. 26 (FIG. c) see Smoothing of the operation of the first and

second stop members

51, 52 required when closing the slide fastener 1 is further promoted. In some cases, additionally or alternatively, the insertion end 73 extends to have a shape according to the contour of the upper wing 41 (or upper wing 41a).

In some cases, the second insertion portion 72 may be a left or right side surface (which may be referred to as a lateral side surface) extending between the front side 42p and the rear side 42q of the lower wing 42 (or upper wing 41) of the slider 40. It extends to have a shape substantially conforming to 42r (see FIG. 4). In brief, the second insertion portion 72 is a left or right side surface (which may be called a lateral side surface) 42r extending between the front side surface 42p and the rear side surface 42q of the lower blade 42a (or the upper blade 41a) of the slider 40. It can extend to have a shape substantially conforming to

In some cases, the upper wing portion 41 and / or the lower wing portion 42 have the

corners

In this case, it is clearly indicated by the arrow D2. The same applies to the inner and outer sides of the first fastener tape 11. The inward of the first fastener tape 11 is clearly shown by the arrow D3. The outward direction of the first fastener tape 11 is clearly shown by the arrow D4.

In some cases, when the second insertion portion 72 is positioned laterally of the upper or

lower flange portions

41b, 42b of the slider 40 in the left-right direction, the extension 75 is at the front portion of the upper or

lower flange portions

41b, 42b. It extends along the left or right side (which may be called the lateral side) and optionally extends substantially parallel. Similarly, when the second insertion portion 72 is positioned to the side of the upper or

lower flange portions

41b, 42b of the slider 40 in the left-right direction, the first inclined portion 76 is a left portion of the rear portion of the upper or

lower flange portions

41b, 42b. Or extending along the right side (which may be referred to as the lateral side) and optionally extending substantially parallel along its entire length. The front and rear portions of the upper and lower flanges are coupled together to form a bend. Similarly, when the second insertion portion 72 is positioned laterally of the upper or

lower flange portions

41b and 42b of the slider 40 in the left-right direction, the second inclined portion 77 extends along the rear surface of the upper blade 41a or the lower blade 42a. Extend, optionally extending substantially parallel. In some cases, the first ramp 76 and the second ramp 77 are provided to intersect at an angle within the range of 85 ° to 95 °.

In some cases, the insertion end 73 is configured to taper outwardly of the second fastener tape 12. The insertion end 73 may be configured in a tapered shape by the downward sloping upper surface and / or the upward sloping lower surface. As described above, the second insertion portion 72 has the insertion end 73 extending so as to have a shape according to the contour of the lower wing 42 (or the lower wing 42 a), and the insertion end 73 A notch 74 is provided to avoid interference with the

Interference with the portion 41 and / or the lower wing portion 42 is avoided or reduced. When the insertion end portion 73 is configured as described above, even if the second insertion portion 72 interferes with the upper wing portion 41 and / or the lower wing portion 42 due to the taper or the tapered shape, the second insertion portion 72 is an upper wing It is possible to move toward the second slit 46 n of the slider 40 by properly avoiding the portion 41 and / or the lower wing portion 42.

The first fastener tape 11, the first fastener element 21 and the first fastener stringer 31 may be alternatively referred to as a left fastener tape, a left fastener element and a left fastener stringer, respectively. The second fastener tape 12, the second fastener element 22, and the second fastener stringer 32 may alternatively be referred to as a right fastener tape, a right fastener element, and a right fastener stringer, respectively. The first retaining member 51 and the second retaining member 52 may alternatively be referred to as a left retaining member and a right retaining member, respectively. Similarly, the first insert 71 and the second insert 72 may alternatively be referred to as a left insert and a right insert, respectively. If appropriate, the first may be replaced by "left" and the second by "right".

The first and

second fastener tapes

11 and 12 may be a flexible woven or knitted fabric. The slider 40 may be made of metal or resin. The first and

second stoppers

51, 52 may be made of resin, but this is not necessarily the case and may be made of other materials such as metal. As one non-limiting example, the fastener element is attached to the fastener tape by injection molding. Subsequently, the retaining member is attached to the fastener tape by injection molding. Subsequently, the fastener elements of one fastener stringer are passed through the slider. Thus, the slide fastener 1 can be manufactured.

Hereinafter, non-limiting features of the first base 61 and the second base 62 will be described with reference to FIGS. 5 and 6. In some cases, the first base 61 of the first stop 51 is provided with a stem 81 and the second base 62 of the second stop 52 is provided with a receptacle 82 for receiving the stem 81. By providing the axial projection 81 on the first base 61, thinning of the second base 62 can be promoted, and the ease of use or the appearance of the slide fastener 1 can be improved. In the first stop member 51, the shaft-like protrusion 81 is provided on the first base 61 using a space for the upper and lower thickness of the slider 40, and the presence of the shaft-like protrusion 81 is provided on the second base 62 Inconspicuous. The axial projection 81 is received by the receiving portion 82, the initial alignment of the first base 61 and the second base 62 is easily or reliably ensured, and / or the rotation of the second base 62 with respect to the first base 61 and The stability of rotation of the first base 61 relative to the second base 62 is enhanced.

In some cases, at least one inclined surface 83 is provided on the outer peripheral portion of the axial projection 81 and inclined in an arc around the center line CX1 of the axial projection 81, and the receiving portion 82 slides on the inclined surface 83 At least one slide 84 is provided which is possible. When the first base 61 and the second base 62 are coaxially arranged, and then the first base 61 and the second base 62 are sandwiched between the thumb and forefinger, the sliding portion 84 descends the inclined surface 83 (FIG. 5). Arrow D5). In this way, the vertical force is converted into a force that causes the first base 61 and / or the second base 62 to rotate. As a result, movement of the second insertion portion 72 toward the second slit 46 n of the slider 40 occurs. In addition, as the sliding portion 84 descends the inclined surface 83, the distance between the first and

second base portions

61 and 62 decreases. When the sliding portion 84 finishes moving down the inclined surface 83, the distance between the first and

second base portions

61, 62 becomes minimum or substantially zero.

The slide 84 projects in some cases into the interior of the receiver 82 and, more particularly, radially inward with respect to the receiver 82 receiving the axial projection 81. Coaxially arranging the first base 61 and the second base 62 is achieved by arranging the first base 61 on the second base 62. At this time, the axial protrusion 81 of the first base 61 is inserted into the receiving portion 82 of the second base 62, and the center line CX1 of the axial protrusion 81 and the center line CX2 of the receiving portion 82 coincide with each other. The coincident center lines CX1 and CX2 are represented as rotation axis AX in FIG. It is also assumed that the first base 61 is disposed on the second base 62 so that the center line CX1 and the center line CX2 do not coincide with each other. Also in such a case, the center line CX1 and the center line CX2 may coincide with each other in the process of sandwiching the first base 61 and the second base 62 between the thumb and the index finger or as a result.

In some cases, the inclined surface 83 has two or more inclined surfaces provided at different positions in the radial direction with respect to the axial projection 81. Additionally, these two or more inclined surfaces may be provided radially adjacent to the axial protrusion 81. In addition, these two or more inclined surfaces are provided at different positions also in the circumferential direction with respect to the axial projection 81. By arranging two or more inclined surfaces having different inclinations and / or surface shapes, it is promoted that the first base 61 and the second base 62 are more properly aligned. As can be clearly seen from FIG. 5, in some cases, the inclined surface 83 is the first inclined surface 83 a provided closer to the inner diameter in the radial direction with respect to the axial protrusion 81 and the outer diameter closer in the radial direction with respect to the axial protrusion 81 And a second inclined surface 83b provided on the The first inclined surface 83a and the second inclined surface 83b are provided adjacent to each other in the radial direction. The first inclined surface 83a and the second inclined surface 83b are provided at different positions in the circumferential direction. The degree of inclination and / or the surface shape of the first inclined surface 83a is different from the degree of inclination and / or the surface shape of the second inclined surface 83b. The form in which the 3rd slope is provided is also assumed.

In some cases, the inclined surface 83 slopes downward so as to be separated from the first fastener tape 11. The thickness decreases in the downward direction on the inclined surface 83. When the inclined surface 83 is inclined downward so as to separate from the first fastener tape 11, a thick portion having a large thickness can be disposed closer to the first fastener tape 11, and a thin portion having a small thickness is separated from the first fastener tape 11. As a result, the attachment strength of the first stop member 51 to the first fastener tape 11 can be enhanced.

In some cases, the sliding portion 84 is in the circumferential direction (e.g., the circumferential direction of the center line CX2 of the receiving portion 82) with respect to the receiving portion 82 that receives the contact edge 84a contacting the inclined surface 83 and the axial projection 81. A protrusion 84b is provided on the opposite side of the contact edge 84a (see FIG. 12), and the axial projection 81 is provided with a recess 81j into which the protrusion 84b is inserted (see FIG. 9). In some cases, when the sliding portion 84 finishes moving down the inclined surface 83, the protrusion 84b and the recess 81j fit. Thereby, the separation of the first base 61 and the second base 62 in the vertical direction is avoided or suppressed. The axial projection 81 has a projection 81c formed by the recess 81j, and a hole 84c for receiving the projection 81c is provided below the projection 84b (see FIG. 12). The holes 84 c penetrate or do not penetrate the second base 62. In some cases, the upper surface of the projection 84b is an inclined surface that inclines downward toward the tip of the projection 84b.

In some cases, the axial protrusion 81 includes a frusto-conical portion 81a and a cylindrical tip portion 81b coupled to the frusto-conical portion 81a. The receiving portion 82 has a main portion 82a for receiving the truncated cone portion 81a and a bottom hole 82b for receiving the cylindrical tip portion 81b. In some cases, the side surface of the cylindrical tip portion 81b has a smaller angle with respect to the center line CX1 of the axial projection 81 than the side surface of the truncated cone portion 81a. In some cases, the side surface of the cylindrical tip 81b includes a region parallel to the center line CX1 of the axial protrusion 81. When the shaft-like protrusion 81 is received by the receiving portion 82, the cylindrical tip 81b fits into the bottom hole 82b, and movement of the cylindrical tip 81b by the bottom hole 82b, which is orthogonal to the vertical direction Its movement in the plane is constrained. Thereby, unintended separation of the first base 61 and the second base 62 is avoided or suppressed.

The axial protrusion 81 may be provided at the central portion of the circular first base 61 when viewed along the vertical direction. The receiving portion 82 may be provided at the central portion of the circular second base 62 as viewed in the vertical direction. The axial projection 81 is provided on the upper surface of the first base 61 and extends along the center line CX1 parallel to the vertical direction. The receiver 82 is provided in a manner to penetrate the second base 62 and extends along the vertically parallel center line CX2.

In some cases, the first stop member 51 has a fin portion 91 provided adjacent to the first fastener element 21. The third fastener element 23 is provided with a groove 92 into which the fin portion 91 is inserted. Assume an incorrect initial state shown in FIG. That is, in FIG. 27, the first base portion 61 is not correctly disposed on the second base portion 62, that is, in the state where the axial projection 81 and the receiving portion 82 are not fitted (in FIG. The portion 81 b is offset from the bottom hole 82 b), and the first insertion portion 71 and the second insertion portion 72 are inserted into the slider 40. In the case where the fin portion 91 is provided, when the slider 40 is advanced from the incorrect initial state shown in FIG. 27, the fin portion 91 of the first insertion portion 71 contacts the connecting post 43, and the left side surface 71k of the first insertion portion 71 Contact the upper flange portion 41b. This prevents the advance of the slider 40. For this reason, the slider 40 is advanced in a state where the axial projection 81 is not properly disposed in the receiving portion 82, and the engagement of the first and

second fastener elements

21 and 22 is avoided or suppressed.

In some cases, the first fastener element 21 comprises an array of first fastener elements 21 and the second fastener element 22 comprises an array of second fastener elements 22. The third fastener element 23 is coupled to the second insert 72 at a position adjacent to the end of the row of second fastener elements 22. As shown in FIG. 17, the third fastener element 23 has a base 23a coupled to the second fastener tape 12, and a head 23c coupled to the base 23a via a neck. The width W23 of the head of the third fastener element 23 along the longitudinal direction of the second fastener tape 12 is 1.4 or more times the pitch interval W22 of the second fastener elements 22 in the row of the second fastener elements 22. In some cases, the width W23 of the head is less than twice the pitch interval W22. It is assumed that the first base 61 is not correctly disposed on the second base 62 (see FIG. 28). In FIG. 28, the first fastener element 21 is inserted into the slider 40, and the third fastener element 23 of the second insertion portion 72 is inserted into the slider 40 from the second front opening 44 n of the slider 40. This is an incorrect initial state in which the first insertion portion 71 is not inserted into the slider 40. Even when trying to advance the slider 40 in this incorrect initial state, the third fastener element 23 is coupled to the first fastener element 21 in the slider 40 in order to satisfy the above-mentioned relationship of the head width W23 to the pitch interval W22. In this case, the first and

second fastener elements

21 and 22 can be prevented or prevented from being bonded while the first and

second stoppers

51 and 52 are not bonded.

FIGS. 17 and 18 show the slide fastener 1 according to an aspect of the present disclosure through rotation of at least one of the first base 61 of the first stopper 51 and the second base 62 of the second stopper 52. FIG. 17 is a schematic view for illustrating movement of the second insertion portion 72 of the second stopping member 52 toward the second slit 46 n of the slider 40 in the process of stacking and combining the two

FIG. 21 is an enlarged schematic view of a range specified by a circle indicated by a broken line in FIG. FIG. 22 is a slide fastener 1 according to an aspect of the present disclosure, in which the fitting portion 71c of the first insertion portion 71 is fitted to the cutout portion 74 provided in the insertion end portion 73 of the second insertion portion 72. It is a schematic cross-sectional schematic diagram which shows a state. FIG. 23 is a schematic top view showing the slide fastener 1 according to an embodiment of the present disclosure in which the first and

second stoppers

51 and 52 are coupled. FIG. 24 is a schematic cross-sectional schematic view taken along the dashed-two dotted line X24-X24 in FIG. It should be noted that in some cases the combination of the first base 61 and the second base 62 means that the separation of both is restricted in at least one arbitrary direction, for example, the vertical direction or the horizontal direction. .

In order to close the first fastener stringer 31 and the second fastener stringer 32, the slider 40 is first disposed on the first stop member 51. The first insertion portion 71 of the first stop member 51 enters the slider 40 through the rear opening 50 of the slider 40. The upper wing portion 41 (or upper wing plate 41a) of the slider 40 contacts the upper stop wall 85a coupled to the upper plate portion 71a of the first insertion portion 71, and the lower wing portion 42 (or lower wing) of the slider 40 The plate 42 a) contacts the lower stop wall 85 b coupled to the lower plate portion 71 b of the first insertion portion 71. The first base 61 and the second base 62 are coaxially arranged, and the axial projection 81 of the first base 61 is inserted into the receiving portion 82 of the second base 62. When the first base 61 and the second base 62 are sandwiched between the thumb and forefinger, the rotation of the first base 61 and / or the second base 62 occurs, and the sliding portion 84 of the second base 62 Go down the inclined surface 83 provided on the outer peripheral portion. At this time, the second insertion portion 72 of the second stopping member 52 moves toward the second slit 46 n of the slider 40 and enters the slider 40 through the second slit 46 n. In addition, the vertical distance between the first base 61 and the second base 62 is narrowed, and finally, the first base 61 is stacked on the second base 62, and both are combined. When the sliding portion 84 finishes moving down the inclined surface 83, the projection 84 b of the sliding portion 84 is inserted into the recess 81 j of the axial projection 81. The second insertion portion 72 is inserted into the insertion groove 80 between the upper plate portion 71 a and the lower plate portion 71 b of the first insertion portion 71 as the slider 40 advances.

As can be seen from FIGS. 19 and 20, in accordance with the rotation of the first base 61 and / or the second base 62, the raised portions 94 provided on the outer peripheral portion of the second base 62 of the second retaining member 52 The small protrusion 95 provided on the lower stop wall 85 b of the first stop member 51 is climbed to reach the recess 96 adjacent to the small protrusion 95. In this process, the vibration is transmitted to the finger of the operator of the slide fastener 1 and the operator of the slide fastener 1 is notified of a state in which the slider 40 can be advanced.

When the slider 40 advances, the connection between the first and

second stop members

51 and 52 is completed. The fin portion 91 of the first retaining member 51 is inserted into the groove 92 of the third fastener element 23 of the second retaining member 52. The fitting portion 71 c provided in the insertion groove 80 of the first stopper member 51 is fitted in the notch portion 74 of the insertion end portion 73 of the second insertion portion 72 of the second stopper member 52. The fitting portion 71 c may be provided on the bottom surface of the insertion groove 80. The fitting portion 71c can be coupled to the upper plate portion 71a and / or the lower plate portion 71b. It is avoided or suppressed that the cylindrical tip portion 81b fits in the bottom hole portion 82b, and the truncated cone portion 81a slides out of the main portion 82a and the first base 61 and the second base 62 are separated.
