Next, utilize Fig. 4～Fig. 7 to describe following state: to make pull head 50 drop to the position of the deutostoma of pull head 50 and the top butt of socket 40B, intubate 30 is plugged in the Plug Division 40Z of socket 40B, then, pull head 50 is moved upward, the zipper teeth chain of left and right is closed each other.

Under the state shown in Fig. 4～Fig. 7, intubate 30 is plugged in the Plug Division 40Z of socket 40B, under this state, intubate 30 becomes by table wall 40C and is positioned, manages with respect to seat the state that 40 sides are positioned by seat pipe side wall surface 40H with respect to the apparent bearing of slide fastener.And the leading section of intubate 30 lower ends becomes the state that is positioned, is positioned with respect to the side separating from seat pipe 40 by separation side anticreep tab 40D with respect to the back of the body direction of slide fastener by back side anticreep tab 40E.

Because back side anticreep tab 40E and separation side anticreep tab 40D are formed as the protuberance that projecting height is lower, so, as shown in Figure 5, with the position of table wall 40C and seat pipe side wall surface 40H face-off on be formed with wide opening 40J.

Below, to without following the operation that pull head 50 is left behind, the order that the zipper teeth chain of the left and right in engagement is ftractureed immediately describes.

As described above, pull head 50 is moved upwards up to behind the shoulder mouth of pull head 50 and the position of upper stop member 18 butts, if user applies the zipper teeth chain of the left and right power that direction is separated to the left and right each other, first the core 14 of the first zipper teeth chain 16 departs from from the trough of belt of pull head 50.

If user is further continuously applied the zipper teeth chain of the left and right power that direction is separated to the left and right each other, below pull head 50 the first chain denture 12 of left and right of engagement and the second chain denture 13 from above remove in order engagement, become the state separating successively, engagement releasing until intubate 30 and seat pipe 40 directly over, become the zipper teeth chain of left and right only by the state of intubate 30 and socket 40B combination.

And if user continues to apply by the zipper teeth chain of the left and right power that direction is separated to the left and right each other, the large opening 40J that intubate 30 limit inclined sides are vacated from the top of back side anticreep tab 40E departs from.Due to this opening 40J vacate larger, so, by making intubate 30 tilt can easily intubate 30 be pulled down from Plug Division 40Z.Therefore, carry out, by the operation that direction is separated to the left and right each other of the zipper teeth chain of left and right, just can promptly intubate 30 being pulled down from socket 40B by lighter power in the case of user.And, as shown in Figure 7, because back side anticreep tab 40E has flexible to the outside deflection of Plug Division 40Z, thus, can limit easily be pulled down intubate 30 by anticreep tab 40E deflection limit, the back side.

, utilize Fig. 8 and Fig. 9 to describe other embodiment of back side anticreep tab below, in intubate 30 is plugged into socket time, this back side anticreep tab is for positioning intubate 30 with respect to the back of the body direction of fast-open type slide fastener 10.

Fig. 8 be represent from the outstanding back side anticreep tab 40E of the lateral margin of the diapire 40G of socket 140B with directly with a figure for the state that the mode that pipe side wall surface 40H is connected forms.In addition, the parts that have an identical function with the parts shown in Fig. 2 are marked to identical Reference numeral and the description thereof will be omitted.

In the embodiment shown in Fig. 2～Fig. 7, between the seat pipe side wall surface 40H of the outstanding back side anticreep tab 40E of the lateral margin of the diapire 40G of socket 40B and socket 40B, directly do not connect, isolate slit 40F but be formed with betwixt.By forming this isolation slit 40F, can make back side anticreep tab 40E easily to the outside deflection of Plug Division 40Z.

But, isolation slit 40F but back side anticreep tab 40E is formed in the outstanding mode of lateral margin of the rear side of the both sides from seat pipe side wall surface 40H and diapire 40G can as shown in Figure 8, be set yet.Like this, even in the case of making back side anticreep tab 40E from the lateral margin of the both sides' of seat pipe side wall surface 40H and diapire 40G rear side extends, thereby the material by suitable adjusting back side anticreep tab 40E and shape make the flexible increase of back side anticreep tab 40E, can obtain thus the structure of easily intubate 30 being pulled down from Plug Division 40Z.

Fig. 9 be represent to make back side anticreep tab 240E as tab the figure from the rear side ora terminalis of the seat pipe side wall surface 40H of socket 240B to the side-prominent embodiment of Plug Division 40Z.In addition, the parts that have an identical function with the parts shown in Fig. 2 are marked to identical Reference numeral, and the description thereof will be omitted.

In the embodiment shown in Fig. 2～Fig. 8, show the embodiment that back side anticreep tab 40E is given prominence to upward from the lateral margin of the diapire 40G of socket 40B, but as shown in Figure 9, make the rear side ora terminalis of the seat pipe side wall surface 40H of back side anticreep tab 240E from socket 240B outstanding, also can make when be applied with about making the zipper teeth chain power that direction is separated to the left and right each other time intubate 30 separately become easy.

In the embodiment shown in Fig. 9, between anticreep tab 240E and the diapire 40G of socket 240B, form overleaf isolation slit 40F, thus, make back side anticreep tab 240E easily to the outside deflection of Plug Division 40Z, become the structure of easily intubate 30 being pulled down from Plug Division 40Z.In addition, in the embodiment shown in Fig. 9, show the embodiment that is formed with overleaf isolation slit 40F between anticreep tab 240E and the diapire 40G of socket 240B, isolate slit but can also form between separation side anticreep tab 40D and the diapire 40G of socket 240B.

The embodiment of other that use that Figure 10 explanation combines the socket of fast-open type pull head and separable bottom end stop of the present invention below.

Figure 10 is the figure that the fast-open type slide fastener 310 that to can not relying on the slip of pull head 350, the zipper teeth chain of closed left and right separated rapidly from face side is observed, and is that upper panel 52 at pull head 350 is (with reference to Figure 11, Figure 12 of hereinafter explanation.) just lower and left and right chain denture just go up the vertical view cutaway drawing that pull head 350 is dissectd.In addition, to parts such as the first zipper teeth chain 16 in fast-open type slide fastener 310, the second zipper teeth chain 17, core 14, the first chain denture 12, the second chain denture 13, intubate 30, seat pipe 40, socket 40B, also the description thereof will be omitted to mark the Reference numeral identical with the parts shown in Fig. 1.

In the inside of pull head 350, for making chain tooth path of navigation that the first chain denture 12 and the second chain denture 13 run through along the fore-and-aft direction of pull head 350 be formed as Y-shaped in the mode of being surrounded by flanging 50F and flanging 50T.In addition, dispose upper panel 52 (with reference to Figure 11 and Figure 12 of subsequent paragraphs explanation at the central portion of the shoulder mouth side of chain tooth path of navigation.) and the link post 50D that links of lower panel 53.

Two ends at chain tooth path of navigation have: the shoulder mouth of left and right, and it is located at the both sides of the link post 50D of the front of pull head 350; Deutostoma, it is located at the rear end side of pull head 350.The shoulder mouth of pull head 350 is for the chain tooth of the left and right separating is imported or derived to chain tooth path of navigation, and deutostoma is for importing the left and right chain tooth of engagement or derive to chain tooth path of navigation.

If make the operation of pull head 350 along the first chain denture 12 and the second chain denture 13 upward slidings, the first chain denture 12 of the left and right in released state and the second chain denture 13 are with engagement from the deutostoma of pull head 350 out.On the contrary, if make the operation of pull head 350 down slidings, the first chain denture 12 in engagement and the second chain denture 13 are imported into from the deutostoma of pull head 350, and the first chain denture 12 and the second chain denture 13 are with released state from the shoulder mouth of left and right out.

Use Figure 11 and Figure 12 that the structure of pull head 350 is described below.Figure 11 is the stereogram of observing pull head 350 from deutostoma side, and Figure 12 is the left side view of pull head 350.

As shown in FIG. 11 and 12, the upper panel 52 of pull head 350 and lower panel 53 link by linking post 50D.Pull head 350 is configured to and comprises: the pull head main body being made up of upper panel 52, lower panel 53, link post 50D; Drawing of operating for user when pull head main body is moved along the length direction of fast-open type slide fastener 310 climbs 59; Have for drawing and climb 59 center of rotation and draw and climb axial region 59A and rotate freely chimeric the drawing of peristome of play and climb erection column 58.

In order to follow the movement of pull head 350 that the first chain denture 12 and the second chain denture 13 are engaged with each other, extend and be provided with

chain tooth flanging

50F, 50T, the 50U of drawing each other that makes both sides in the edge, both sides of upper panel 52 and lower panel 53.Offer at the flanging 50F of upper panel 52 and lower panel 53 gap portion respect to one another and the flanging 50T gap portion relative with flanging 50U the trough of belt that the zipper strip for making the first zipper teeth chain 16 and the second zipper teeth chain 17 runs through.

Be formed on the trough of belt in flanging 50F part respect to one another, as shown in the side view of Figure 12, from shoulder mouthful side to deutostoma side with certain gap h ' formation.Because this trough of belt is that zipper strip for making the second zipper teeth chain 17 runs through the gap of offering, so the gap h ' of trough of belt is slightly wider than the thickness of zipper strip, slightly narrower than the thickness of the second chain denture 13, is set to the gap same with common pull head.

In contrast, the trough of belt of the gap portion that

flanging

50T, 50U are relative, as shown in the side view of Figure 12, the extension that the extension that is set to the flanging 50T that makes shoulder mouthful side place arranges aspect ratio central portion arranges highly low tilted shape.Thus, the gap H of the trough of belt of shoulder mouthful side can be set as to wide cut, and the gap h of the trough of belt of deutostoma side is set narrowly.

In addition, in the embodiment shown in Figure 12, the gap h of the trough of belt of deutostoma side is set as wider than the gap h ' of the trough of belt of flanging 50F side, but also can be according to flexible (the hereinafter explanation of upper panel 52.) and the gap h of the trough of belt of deutostoma side is set as to the degree of the gap h ' of the trough of belt that is too narrow to flanging 50F side.In addition, can also be according to upper panel 52 flexible, the gap of trough of belt is set as to certain gap.

In the embodiment shown in Figure 12, extend from the lower panel 53 of pull head 350 the flanging 50U arranging, be set to certain short extension from shoulder mouthful side to deutostoma height is set.In contrast, extend from upper panel 52 extension that extension that the flanging 50T arranging is set to shoulder mouthful side arranges aspect ratio central portion highly low tilted shape is set.In addition, as other embodiment, also can with the embodiment shown in Figure 12 on the contrary, the flanging that extends setting from upper panel 52 is set to certain low extension from shoulder mouthful side to deutostoma height is set, and the extension that the extension that the flanging that extends setting from lower panel 53 is set as shoulder mouthful side arranges aspect ratio central portion is arranged to highly low tilted shape.

, use Figure 13～Figure 15 below, flexible the describing when chain tooth and zipper teeth chain being pulled down in the lump on the pull head 350 from present embodiment.Figure 13 be the XIII-XIII shown in Figure 10 to looking cutaway view, Figure 14 is that the XIV-XIV shown in Figure 10 is to looking cutaway view.In addition, Figure 15 is that the XV-XV shown in Figure 10 is to looking cutaway view.In addition,, for the part identical with the part shown in Figure 10 and Figure 11, also the description thereof will be omitted to mark identical Reference numeral.

Figure 13～Figure 15 is respectively the chain tooth path of navigation of pull head 350 and the cutaway view of the first zipper teeth chain 16, is the cutaway view of observing to shoulder mouthful side from the inside of chain tooth path of navigation.Because the cross section shown in Figure 13 is the cutaway view of the part of the shoulder mouth of close pull head 350, so the extension of flanging 50T arranges altimeter and is shown minimum.Because the cross section shown in Figure 14 slightly approaches deutostoma side compared with the position shown in Figure 13, so compared with the state shown in Figure 13, the extension of flanging 50T arranges and highly represents highlyer.In the cross section shown in Figure 15, owing to more approaching deutostoma side, so compared with the state shown in Figure 14, the extension of flanging 50T arranges and highly represents get Geng Gao.

Like this, because arranging the deutostoma direction being highly set to along with approaching pull head 350, the extension of flanging 50T increases, so, make the first chain denture 12 of the released state being imported into from the shoulder mouth of pull head 350 engage with the second chain denture 13 of face-off in order to follow moving of pull head 350, can the chain tooth drawing each other that make both sides in highly higher part be set in the extension of flanging 50T.

In addition, pull head of the present invention 350 is preferably shaped by the flexible resin forming product that has of crystallinity polyamide etc.There is flexible material by use, can make the apparent bearing deflection shown in the double dot dash line of

flanging

50T, 50U side direction Figure 13 of the upper panel 52 of pull head 350.On the other hand, the material of first and

second chain denture

12,13 preferably uses the spring rate acetal resin more contour than described crystallinity polyamide etc.The material of pull head 350 and first and

second chain denture

12,13 is not limited to aforesaid example, but the preferred at least spring rate of the material of pull head 350 is set lowlyer than the spring rate of the material of first and second chain tooth example 12,13.

Below, to make to separate in 310 moments of fast-open type slide fastener of blocking operation time, the relation of pull head 350 and the first chain denture 12 describes.In the side of pull head 350, if apply the first zipper teeth chain 16 of left and right and the second zipper teeth chain 17 power that direction is separated to the left and right, the chain tooth of the most close shoulder of the first chain denture 12 mouthful side will enter into the trough of belt extending between flanging 50T, the 50U that the shoulder mouth side that height setting must be lower is set.Now, the chain tooth of the most close shoulder mouthful side of the first chain denture 12 makes the bight deflection upward of flanging 50T and upper panel 52.Its result is that the trough of belt of shoulder mouthful side is widened, and becomes the state that the first chain denture 12 is nipped in trough of belt.

And then, apply the first zipper teeth chain 16 and the second zipper teeth chain 17 power that direction is separated to the left and right that make left and right if continue, the chain tooth that bites into the first chain denture 12 in trough of belt is crossed

flanging

50T, 50U, and as shown in the imaginary line of Figure 13, depart from from the chain tooth path of navigation of pull head completely.

In the embodiment shown in Figure 13, the flanging 50T side showing at upper panel 52 has flexible embodiment, but also can, so that the mode of the flanging 50U side direction back of the body direction deflection of lower panel 53 has flexiblely, can also be configured to upper panel 52 and lower panel 53 both sides have flexible.

In addition, in the time applying the first zipper teeth chain 16 of left and right and the second zipper teeth chain 17 power that direction is separated to the left and right, for

flanging

50T, 50U are easily taken in the first chain denture 12, can on the bight of flanging 50T, the 50U of the 50V of the portion of taking of

flanging

50T, 50U and the first chain denture 12 initial butts, form C chamfering or R chamfering.In addition, can also form C chamfering or R chamfering in the bight of the first chain denture 12.

, use Figure 16～Figure 19 below, the action when operation zipper teeth chain of closed left and right being separated rapidly to not relying on the slip of pull head, the first chain denture 12 describes.

Figure 16 is illustrated in the part of shoulder mouth of the close pull head 350 shown in Figure 13, the vertical view cutaway drawing of the state in the trough of belt that the chain tooth 12-1 of the most close shoulder in the first chain denture 12 in the chain tooth path of navigation that is present in pull head 350 mouthful starts to nip between the opposite face of

flanging

50T, 50U most.In addition, Figure 17 is illustrated near the cross section shown in Figure 14 the nip vertical view cutaway drawing of the state in trough of belt of second chain tooth 12-2.Figure 18 is that the 3rd chain tooth 12-3 who represents engagement further separates from the state shown in Figure 17, again the nip vertical view cutaway drawing of the state in trough of belt of the chain tooth of this separation.The figure of the state that Figure 19 is that the engagement that represents whole chain tooth of the chain tooth path of navigation that enters into pull head 350 is disengaged, the first zipper teeth chain 16 of left and right and the second zipper teeth chain 17 separate.

For example, the first zipper teeth chain 16 is seamed on the lateral margin of center side of the left front body hunk of clothes, the second zipper teeth chain 17 is seamed on the lateral margin of center side of right front body hunk, the situation that the state in engagement separates the first zipper teeth chain 16 of left and right and the second 17 moments of zipper teeth chain from the first chain denture 12 and the second chain denture 13 is described.

First, make the first chain denture 12 and the second chain denture 13 become engagement.Then,, in the side of pull head 350, the first zipper teeth chain 16 and the second zipper teeth chain 17 to left and right apply respectively the power that direction is pulled open to the left and right as shown in arrow in Figure 17.

Like this, as shown in figure 16, initial, first chain tooth 12-1 of the first zipper teeth chain 16 in the part of the shoulder mouth near pull head 350, the state in the trough of belt in the flanging 50T side of nipping.Now, have flexible upper panel 52 to apparent bearing deflection, trough of belt is widened.

Separate if the first zipper teeth chain 16 about further making from the state shown in Figure 16 and the second zipper teeth chain 17 continue direction to the left and right, upper panel 52 is further to apparent bearing deflection, and the chain tooth of nipping is further widened trough of belt.Like this, as shown in figure 17, become the state that second continuous chain tooth 12-2 nips in the trough of belt of flanging 50T side.

The first zipper teeth chain 16 about further making from the state shown in Figure 17 and the second zipper teeth chain 17 to the left and right direction separate, and second the chain tooth 12-2 nipping in trough of belt makes upper panel 52 to apparent bearing deflection, and trough of belt is further widened.Then, chain tooth 12-3 in the chain tooth of the first chain denture 12 and the second chain denture 13, in engagement, as shown in figure 18, separates from the chain tooth of engagement object, meanwhile, become the state in the trough of belt that a part of the chain tooth 12-3 of the first chain denture 12 nips between

flanging

50T, 50U.

Separate if the first zipper teeth chain 16 about further making from the state shown in Figure 18 and the second zipper teeth chain 17 continue direction to the left and right, the chain tooth 12-3 nipping further widens trough of belt.Then,, in the chain tooth path of navigation of pull head 350, the engagement of the chain tooth 12-4 of engagement is disengaged.Like this, be present in multiple chain tooth 12-1～12-4 in the chain tooth path of navigation of pull head 350 from shoulder mouthful side in order by the trough of belt between flanging 50T, the 50U of pull head 350, final, the first chain denture 12 departs from completely from the chain tooth path of navigation of pull head 350.In the first chain denture 12, from the chain tooth path of navigation of pull head 350 departs from, the deflection (strain) of the upper panel 52 of the chain tooth of nipping is before this restored, and returns to free position (position shown in the solid line of Figure 13) originally.

Once the first chain denture 12 departs from from pull head, the first chain denture 12 and the second chain denture 13 that are engaged on the left and right of the below of pull head 350 are removed engagement in order from top, as shown in figure 19, become state separately.And, once make the first chain denture 12 of left and right and the second chain denture 13 separately, become intubate 30 from socket 40B extract, the first zipper teeth chain 16 and the distinct state of the second zipper teeth chain 17 of left and right.

The situation that makes the first zipper teeth chain 16 of distinct left and right and the second zipper teeth chain 17 again become engagement is described.In this situation, first make pull head 350 drop to the most the next of the second zipper teeth chain 17, make the deutostoma butt of socket 40B and pull head 350.

Then, the first zipper teeth chain 16 is inserted from the shoulder mouth in the left side of pull head 350, the bottom of intubate 30 is pushed until the Plug Division 40Z that is plugged on socket 40B (with reference to Fig. 2.) in.If continue the application of force in the direction that intubate 30 is declined, last, in the second engaging portion 44 of the present pipe 40 of the first engaging portion 34 butts of intubate 30.If make the operation of pull head 350 to pull-up above slide fastener under the state that this intubate 30 is plugged into lower end, the first chain denture 12 and the second chain denture 13 engage and from the deutostoma of pull head 350 out.Like this, can, by the left front body hunk of clothes and right front body hunk closure, both sides' front body hunk be bonded to each other.

In addition, in the embodiment shown in Figure 12, extend the flanging 50U arranging from the lower panel 53 of pull head 350 and be set as certain short extension from shoulder mouthful side to deutostoma height is set, extend from upper panel 52 extension that extension that the flanging 50T arranging is set to its shoulder mouthful side arranges aspect ratio central portion highly low tilted shape is set.

In addition, can also the gap H of the trough of belt of shoulder mouthful side be set as to wide cut by the flanging that forms as shown below pull head, and the gap h of the trough of belt of deutostoma side is set narrowlyer.

For example, can also abandon the lower panel 53 from pull head 350 shown in Figure 11 and extend the flanging 50U arranging, by the extension that makes to extend from upper panel 52 the flanging 50T arranging, highly entirety being set improves, and the gap H of the trough of belt of shoulder mouthful side is set as to wide cut, and make the gap h of the trough of belt of deutostoma side set narrowlyer.

In addition, can also abandon on the contrary from the upper panel of pull head and extend the flanging arranging, the extension that aspect ratio central portion is set by the shape of extending the flanging arranging from lower panel being set as to the extension of its shoulder mouthful side arranges highly low tilted shape, and the gap H of the trough of belt of shoulder mouthful side is set as to wide cut, the gap h of the trough of belt of deutostoma side is set narrowlyer.

In addition, in addition, extend the both sides' that arrange flanging about the upper panel from pull head and lower panel, the extension that aspect ratio central portion can also be set to become the extension of shoulder mouthful side arranges the mode of highly low tilted shape and sets, thus, the gap H of the trough of belt of shoulder mouthful side can be set as to wide cut, and the gap h of the trough of belt of deutostoma side is set narrowlyer.

In addition, the extension that can make the extension of the shoulder mouth side of flanging that aspect ratio central portion is set arranges in the part that highly low tilted shape is only formed on flanging, and remaining part is formed as parallel with upper panel or lower panel.In addition, can also with above-mentioned embodiment on the contrary, the extension that the extension of the deutostoma side of flanging is arranged to aspect ratio central portion arranges highly low tilted shape and is formed on flanging.The extension that aspect ratio central portion is set by being formed as the extension of deutostoma side of flanging arranges highly low tilted shape, can make band run through road from deutostoma side and expand, make chain denture pull down and become easy from pull head.

In addition, the extension that the extension that the extension that the extension that has the shoulder mouth side of flanging concurrently by use arranges aspect ratio central portion arranges the deutostoma side of highly low tilted shape and flanging arranges aspect ratio central portion arranges the flanging of highly low tilted shape, coordinate or head cooperation by afterbody, can be by this structure for making the separation of the slide fastener of configuration relatively of multiple pull heads.

, use Figure 20～Figure 22 below, thereby to by making at least either party deflection in upper panel and lower panel can make the embodiment that band runs through the pull head of widening on road describe.Figure 20 is to being formed on the stereogram that the pull head 650 on upper panel 52 is observed from deutostoma side for obtaining flexible thinner wall section 54.In addition, Figure 21 is the figure that the pull head 650 shown in Figure 20 is observed from deutostoma side.Figure 22 is to being formed on the figure that the pull head 750 on upper panel 52 and lower panel 53 both sides is observed from deutostoma side for obtaining flexible thinner wall section.In addition, the part that has an identical function with the part shown in Figure 11, Figure 12 etc. is marked to identical Reference numeral and the description thereof will be omitted.

On the upper surface of the right flank side of the upper panel 52 in the pull head 650 shown in Figure 20 and Figure 21, within the scope of the fore-and-aft direction of pull head 650, be formed with slot part 55.The dorsal part (chain tooth path of navigation side) of this slot part 55 is formed as plane, so, be formed with thinner wall section 54 in the bottom of slot part 55.Like this, on upper panel 52, spread all over pull head 650 fore-and-aft direction be formed with thinner wall section 54, thus, can make take this thinner wall section 54 as fulcrum the easily deflection upward of flanging 650T side of upper panel 52.By with easily make this flanging 650T upward the mode of deflection form, the band that can widen pull head 650 runs through road, and chain denture is easily departed from from chain tooth path of navigation.

In addition,, in the embodiment shown in Figure 20 and Figure 21, in order easily to carry out pulling down of chain denture, the extension of flanging 650U and flanging 650T is arranged to height setting and must arrange than the extension of flanging 50F highly low.Thus, gap H is formed as wider than the gap h ' of flanging 50F side.

In addition, in the embodiment shown in Figure 20 and Figure 21, the gap H that band runs through road is set to certain gap from shoulder mouthful to deutostoma, but this band runs through the gap on road, also can make the gap H that the band of shoulder mouthful side or deutostoma side runs through road be set as wide cut, and to be formed as tilted shape towards the mode of central portion gap turn narrow.

In addition, in the embodiment shown in Figure 20 and Figure 21, show on the upper surface by the upper panel 52 in left side and form slot part 55, thereby form the embodiment of thinner wall section 54 in the bottom of slot part 55, but the invention is not restricted to which, can also on the both sides of the single-blade side of the left and right of left wing's side of upper panel 52, upper panel 52 two flanks, lower panel 53 or two flanks, upper panel 52 and lower panel 53, form slot part 55 and thinner wall section 54, can widen thereby become the structure that band runs through road.

In addition, slot part 55 can also be opened in to chain tooth path of navigation side, make thinner wall section 54 be formed on the upside of upper panel 52.In addition, can also offer slot part from the upside of upper panel 52 and chain tooth path of navigation side both sides.Similarly, can also offer slot part from the downside of lower panel 53 and chain tooth path of navigation side both sides.

, use Figure 22 below, the embodiment that forms thinner wall section 54 on the upper panel 52 at pull head 750 and lower panel 53 both sides is described.In the embodiment shown in Figure 20 and Figure 21, show fore-and-aft direction by spreading all over pull head 650 and offer slot part 55 and form the embodiment of thinner wall section 54 in the bottom of this slot part 55.In contrast, can also be as shown in figure 22 like that, form the flat thinner wall section 54 that spreads all over the fore-and-aft direction of pull head 750 and left and right directions by roughly thickness forms uniformly.

By forming as illustrated in fig. 22 thinner wall section 54, in the time that the zipper teeth chain of left and right is applied to lateral pull, can easily make upper panel 52 and lower panel 53 both sides' deflections.And, widen band and run through road, thereby can easily pull down chain denture from chain tooth path of navigation.
