Mode with deflection laterally easily constitutes back side anticreep tab 40E, thus, under the situation that the first chain denture 12 and the second chain denture 13 are engaged with each other, even when carrying out the washing of clothes, under the situation of the power that is applied with compressing on intubate 30 and the socket 40B, because intubate 30 can break away from from socket 40B because of more weak power, so, can make intubate 30 and socket 40B that damaged unfavorable condition takes place and reduce.

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

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

Because back side anticreep tab 40E and separate side anticreep tab 40D and form the lower protuberance of projecting height, 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, make need not to follow the operation that pull head 50 is left behind be in engagement about the order that ftractures immediately of zipper teeth chain describe.

As described above, make pull head 50 be moved upwards up to pull head 50 the shoulder mouth and on end the position of part 18 butts after, if the user apply with about the zipper teeth chain direction power of separating to the left and right each other, then at first the core 14 of first zipper teeth chain 16 breaks away from from the trough of belt of pull head 50.

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

And, if the user continue to apply with about the zipper teeth chain direction power of separating to the left and right each other, then the big opening 40J that vacates from the top of back side anticreep tab 40E of intubate 30 limit inclined sides breaks away from.Because it is bigger that this opening 40J vacates, so, tilt can easily intubate 30 be pulled down from Plug Division 40Z by making intubate 30.Therefore, the user carry out with about zipper teeth chain each other under the situation of the operation that separates of direction to the left and right, just can promptly intubate 30 be pulled down from socket 40B by lighter power.And, as shown in Figure 7,, thus, can the limit easily be pulled down intubate 30 by anticreep tab 40E deflection limit, the back side because back side anticreep tab 40E has flexible to the deflection of the outside of Plug Division 40Z.

Below, utilize Fig. 8 and Fig. 9 that other embodiment of back side anticreep tab is described, when being plugged into intubate 30 in the socket, this back side anticreep tab is used for the back of the body direction of intubate 30 with respect to fast-open type slide fastener 10 positioned.

Fig. 8 is expression from the figure of the outstanding back side anticreep tab 40E of the lateral margin of the diapire 40G of socket 140B with the state that directly forms with seat pipe side wall surface 40H ways of connecting.In addition, to having the identical Reference numeral of the parts mark of identical function and omit its explanation with parts shown in Figure 2.

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

But, can as shown in Figure 8, not be provided with yet and isolate slit 40F but back side anticreep tab 40E is formed in the outstanding mode of lateral margin from the both sides' of seat pipe side wall surface 40H and diapire 40G rear side.Like this, even under the situation that the lateral margin that makes back side anticreep tab 40E from the both sides' of seat pipe side wall surface 40H and diapire 40G rear side extends, thereby the flexible increase that material and shape by suitable adjusting back side anticreep tab 40E make back side anticreep tab 40E can access the structure of easily intubate 30 being pulled down from Plug Division 40Z thus.

Fig. 9 is that expression makes back side anticreep tab 240E manage the figure of the rear side ora terminalis of side wall surface 40H to the side-prominent embodiment of Plug Division 40Z as tab from the seat of socket 240B.In addition, to having the identical Reference numeral of parts mark of identical function, and omit its explanation with parts shown in Figure 2.

In the embodiment of Fig. 2～shown in Figure 8, show and make back side anticreep tab 40E from the outstanding upward embodiment of 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 zipper teeth chain each other to the left and right direction separate power the time intubate 30 separately become easy.

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

Below, the embodiment of other that use that Figure 10 explanation makes up the socket of fast-open type pull head and grafting-separate pieces of the present invention.

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

In the inside of pull head 350, be used to make 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 to form the Y font in the mode of being surrounded by flanging 50F and flanging 50T.In addition, the central portion at the shoulder oral-lateral of chain tooth path of navigation disposes upper panel 52 (with reference to Figure 11 and Figure 12 of subsequent paragraphs explanation.) and the binding post 50D that links of lower panel 53.

Two ends at chain tooth path of navigation have: about the shoulder mouth, it is located at the both sides of binding 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 used for the chain tooth about separating is imported or derives to chain tooth path of navigation, and deutostoma is used for the left and right sides chain tooth of engagement is imported or derives to chain tooth path of navigation.

If the operation that pull head 350 is upwards slided along the first chain denture 12 and the second chain denture 13, then be in released state about the first chain denture 12 and the second chain denture 13 come out with the deutostoma of engagement from pull head 350.On the contrary, if make the operation of pull head 350, then be in the first chain denture 12 of engagement and the second chain denture 13 and be imported into from the deutostoma of pull head 350 to lower slider, the first chain denture 12 and the second chain denture 13 with released state from about the shoulder mouth come out.

Below, use Figure 11 and Figure 12 that the structure of pull head 350 is described.Figure 11 is a stereogram of observing pull head 350 from the back oral-lateral, and Figure 12 is the left side view of pull head 350.

As Figure 11 and shown in Figure 12, the upper panel 52 of pull head 350 and lower panel 53 link by linking post 50D.Pull head 350 constitutes and comprises: by upper panel 52, lower panel 53, link the pull head main body that post 50D constitutes; Make the pull head main body climb 59 for drawing of operating of user when the length direction of fast-open type slide fastener 310 moves; Have for drawing and climb 59 center of rotation and promptly draw and climb axial region 59A and rotate freely chimeric the drawing of peristome of play and climb erection column 58.

For the mobile first chain denture 12 and the second chain denture 13 of making of following pull head 350 is engaged with each other, extends in the both side edges portion of upper panel 52 and lower panel 53 and to be provided with

chain tooth flanging

50F, 50T, the 50U of drawing each other that makes both sides.Offer the trough of belt that the zipper strip that is used to make first zipper teeth chain 16 and second zipper teeth chain 17 runs through 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.

Be formed on the trough of belt on the flanging 50F part respect to one another, shown in the side view of Figure 12, from the shoulder oral-lateral to the back oral-lateral with certain clearance h ' formation.Owing to this trough of belt is for the zipper strip that makes second zipper teeth chain 17 runs through the gap of offering, narrower slightly so the gap h ' of trough of belt is wideer slightly than the thickness of zipper strip than the thickness of the second chain denture 13, be set to the gap same with common pull head.

With it relatively, the trough of belt of the gap portion that

flanging

50T, 50U are relative, shown in the side view of Figure 12, the extension that the extension that is set to the flanging 50T that makes shoulder oral-lateral place is provided with the aspect ratio central portion is provided with highly low tilted shape.Thus, the gap H that takes on the trough of belt of oral-lateral can be set at wide cut, and the gap h of the trough of belt of oral-lateral sets narrowly after inciting somebody to action.

In addition, in embodiment shown in Figure 12, the gap h of trough of belt of back oral-lateral is set at wideer 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 trough of belt that will the back oral-lateral is set at 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 at certain clearance.

In embodiment shown in Figure 12, extend the flanging 50U that is provided with from the lower panel 53 of pull head 350, be set to certain short extension from the shoulder oral-lateral to deutostoma height is set.With it relatively, extend the extension that extension that the flanging 50T that is provided with is set to the shoulder oral-lateral is provided with the aspect ratio central portion from upper panel 52 highly low tilted shape is set.In addition, as other embodiment, also can with embodiment shown in Figure 12 on the contrary, to extend the flanging that is provided with from upper panel 52 and be set to certain low extension from the shoulder oral-lateral to deutostoma height is set, highly low tilted shape will be set and will extend the extension that extension that the flanging that is provided be set at the shoulder oral-lateral is provided with the aspect ratio central portion from lower panel 53.

Below, use Figure 13～Figure 15, flexible the describing when on the pull head from present embodiment 350 chain tooth and zipper teeth chain being pulled down in the lump.Figure 13 is XIII-XIII shown in Figure 10 to looking cutaway view, and Figure 14 is that XIV-XIV shown in Figure 10 is to looking cutaway view.In addition, Figure 15 is that XV-XV shown in Figure 10 is to looking cutaway view.In addition, for Figure 10 and the identical part of part shown in Figure 11, mark identical Reference numeral and omit its explanation.

Figure 13～Figure 15 is respectively the chain tooth path of navigation of pull head 350 and the cutaway view of first zipper teeth chain 16, is the cutaway view of observing to the shoulder oral-lateral from the inside of chain tooth path of navigation.Because cross section shown in Figure 13 is the cutaway view near the part of the shoulder mouth of pull head 350, so the extension of flanging 50T is provided with altimeter and is shown minimum.Because approaching slightly back oral-lateral is compared in cross section shown in Figure 14 with position shown in Figure 13, so, to compare with state shown in Figure 13, the extension of flanging 50T is provided with highly to be represented higherly.In cross section shown in Figure 15, because more approaching back oral-lateral, so, to compare with state shown in Figure 14, the extension of flanging 50T is provided with highly represents De Genggao.

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

In addition, pull head of the present invention 350 preferably is shaped by the flexible resin forming product that has of crystallinity polyamide etc.Have 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 spring rate of the material of pull head 350 is at least set lowlyer than the spring rate of the material of first and second chain tooth example 12,13.

Below, relation when making the operation that 310 moments of fast-open type slide fastener of being in blocking separate, pull head 350 and the first chain denture 12 describes.Side at pull head 350, if apply with about first zipper teeth chain 16 and the second zipper teeth chain 17 direction power of separating to the left and right, then the chain tooth of the most close shoulder oral-lateral of the first chain denture 12 will enter into the trough of belt that extends between flanging 50T, the 50U that the shoulder oral-lateral that height setting must be lower is set.At this moment, the chain tooth of the most close shoulder oral-lateral of the first chain denture 12 makes the bight deflection upward of flanging 50T and upper panel 52.Its result is, the trough of belt of shoulder oral-lateral is widened, and becomes nip state in the trough of belt of the first chain denture 12.

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

flanging

50T, 50U, and shown in the imaginary line of Figure 13 like that, break away from from the chain tooth path of navigation of pull head fully.

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

In addition, apply with about first zipper teeth chain 16 and second zipper teeth chain 17 to the left and right direction separate power the time, for

flanging

50T, 50U are taken easily on 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.

Below, use Figure 16～Figure 19, the action during operation that separates rapidly to the slip that do not rely on pull head and with the zipper teeth chain about closure, the first chain denture 12 describes.

Figure 16 is illustrated in the part of shoulder mouth of close pull head 350 shown in Figure 13, the chain tooth 12-1 of the most close shoulder in the first chain denture 12 in being present in the chain tooth path of navigation of pull head 350 mouthful begin most the to nip vertical view cutaway drawing of the state in the trough of belt between the opposite face of flanging 50T, 50U.In addition, Figure 17 is illustrated near the nip vertical view cutaway drawing of the state in the trough of belt of second the chain tooth 12-2 cross section shown in Figure 14.Figure 18 is that the 3rd chain tooth 12-3 of expression engagement further separates from state shown in Figure 17, nip the again vertical view cutaway drawing of the state in the trough of belt of the chain tooth of this separation.Figure 19 be the engagement of whole chain teeth that expression enters into the chain tooth path of navigation of pull head 350 be disengaged, about first zipper teeth chain 16 and the figure of the state that separates of second zipper teeth chain 17.

For example, first zipper teeth chain 16 is seamed on the lateral margin of center side of left front body sheet of clothes, second zipper teeth chain 17 is seamed on the lateral margin of center side of right front body sheet, to the state that is in engagement from the first chain denture 12 and the second chain denture 13 with about first

zipper teeth chain

16 and 17 moments of second zipper teeth chain situation of separating describe.

At first, make the first chain denture 12 and the second chain denture 13 become engagement.Then, in the side of pull head 350, to about first zipper teeth chain 16 and second zipper teeth chain 17 shown in arrow among Figure 17, apply like that the power that direction is to the left and right drawn back respectively.

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

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

First zipper teeth chain 16 about further making from state shown in Figure 17 and second zipper teeth chain 17 to the left and right direction separately, second chain tooth 12-2 in the trough of belt of then nipping makes upper panel 52 to the apparent bearing deflection, 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, that be in engagement, as shown in figure 18, from the chain tooth separation of engagement object, simultaneously, a part that becomes the chain tooth 12-3 of the first chain denture 12 state in the trough of belt between flanging 50T, the 50U of nipping.

If first zipper teeth chain 16 about further making from state shown in Figure 180 and second zipper teeth chain 17 continue to the left and right direction separately, the chain tooth 12-3 that then nips 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 a plurality of chain tooth 12-1～12-4 in the chain tooth path of navigation of pull head 350 from the shoulder oral-lateral in order by the trough of belt between flanging 50T, the 50U of pull head 350, final, the first chain denture 12 breaks away from fully from the chain tooth path of navigation of pull head 350.After the chain tooth path of navigation disengaging of pull head 350, 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 in the first chain denture 12.

In case the first chain denture 12 breaks away from from pull head, then be engaged on pull head 350 the below about the first chain denture 12 and the second chain denture 13 remove engagement in order from the top, as shown in figure 19, become state separately.And, in case the first chain denture 12 about making and the second chain denture 13 are separately, then become intubate 30 from socket 40B extract, about first zipper teeth chain 16 and second zipper teeth chain, 17 distinct states.

The situation that makes first zipper teeth chain 16 about distinct and second zipper teeth chain 17 become engagement is once more described.Under this situation, at first make pull head 350 drop to the most the next of second zipper teeth chain 17, make the deutostoma butt of socket 40B and pull head 350.

Then, the shoulder mouth of first zipper teeth chain 16 from the left side of pull head 350 inserted, 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 on the direction that intubate 30 is descended, continue the application of force, last, in the second fastening portion 44 of the present pipe 40 of the first fastening portion, 34 butts of intubate 30.If under the state that this intubate 30 is plugged into the lower end, make the operation of pull head 350 pull-up above slide fastener, the then

first chain denture

12 and 13 engagements of the second chain denture and come out from the deutostoma of pull head 350.Like this, can the large stretch of and right front body of the left front body of clothes is large stretch of closed, both sides' front body hunk is bonded to each other.

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

In addition, can also the gap H that take on the trough of belt of oral-lateral be set at wide cut by the flanging that forms pull head as followsly, and the gap h of the trough of belt of oral-lateral sets narrowlyer after inciting somebody to action.

For example, can also abandon the lower panel 53 from pull head 350 shown in Figure 11 and extend the flanging 50U that is provided with, by making the extension of extending the flanging 50T that is provided with that highly whole the raising is set from upper panel 52, and the gap H that will take on the trough of belt of oral-lateral is set at wide cut, and makes the gap h of the trough of belt of back oral-lateral set narrowlyer.

In addition, can also abandon on the contrary from the upper panel of pull head and extend the flanging that is provided with, by will for the extension that its extension of takeing on oral-lateral is provided with the aspect ratio central portion highly low tilted shape being set from the shape set that lower panel extends the flanging that is provided with, and the gap H that will take on the trough of belt of oral-lateral is set at wide cut, sets the gap h of trough of belt of back oral-lateral narrower.

In addition, in addition, extend the both sides' that are provided with flanging about upper panel and lower panel from pull head, the extension that can also the aspect ratio central portion be set with the extension that becomes the shoulder oral-lateral is provided with the mode of highly low tilted shape and sets, thus, the gap H that takes on the trough of belt of oral-lateral can be set at wide cut, and the gap h of the trough of belt of oral-lateral sets narrowlyer after inciting somebody to action.

In addition, the extension that can make the extension of the shoulder oral-lateral of flanging that the aspect ratio central portion is set is provided with on the part that highly low tilted shape only is formed on flanging, and remaining part is formed 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 back oral-lateral of flanging is provided with the aspect ratio central portion is provided with highly low tilted shape and is formed on the flanging.The extension that the extension of the back oral-lateral by forming flanging is provided with the aspect ratio central portion is provided with highly low tilted shape, can make the coherent road of wearing expand and open from the back oral-lateral, the chain denture is pulled down from pull head become easy.

In addition, the extension that the extension that the extension that the extension that has the shoulder oral-lateral of flanging concurrently by use is provided with the aspect ratio central portion is provided with the back oral-lateral of highly low tilted shape and flanging is provided with the aspect ratio central portion is provided with the flanging of highly low tilted shape, cooperate or the head cooperation by afterbody, this structure can be used to make the separation of the slide fastener of configuration relatively of a plurality of pull heads.

Below, use Figure 20～Figure 22, thereby to by making the deflection of either party at least in upper panel and the lower panel that the coherent embodiment of wearing the pull head of widening on the road is described.Figure 20 is formed on the stereogram that the pull head 650 on the upper panel 52 is observed from the back oral-lateral to being used to obtain flexible thinner wall section 54.In addition, Figure 21 is the figure that pull head shown in Figure 20 650 is observed from the back oral-lateral.Figure 22 is formed on the figure that the pull head 750 on upper panel 52 and lower panel 53 both sides is observed from the back oral-lateral to being used to obtain flexible thinner wall section.In addition, to having the identical Reference numeral of the part mark of identical function and omit its explanation with the part shown in Figure 11, Figure 12 etc.

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

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

In addition, in Figure 20 and embodiment shown in Figure 21, the coherent gap H that wears the road is set to certain clearance from the shoulder mouth to deutostoma, but this coherent gap of wearing the road, also can make the coherent gap H that wears the road of shoulder oral-lateral or back oral-lateral be set at wide cut, and form tilted shape in mode towards the central portion gap turn narrow.

In addition, in Figure 20 and embodiment shown in Figure 21, show by on the upper surface of the upper panel 52 in left side, forming 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 this mode, can also on the both sides of the single-blade side of two flanks, lower panel 53 about left wing's side of upper panel 52, upper panel 52 or two flanks, upper panel 52 and lower panel 53, form slot part 55 and thinner wall section 54, can widen coherent structure of wearing the road thereby become.
