As shown in Fig. 3 and Fig. 5 B, absorbent main body 10 comprises: absorbent cores 11, and described absorbent cores 11 is made by being configured as by the paper pulp fiber of an example as liquidabsorbing fibres from the general hourglass shape (example as reservation shape) during top view; Surficial sheets component 13, described surficial sheets component 13 covers absorbent cores 11 from the skin side of absorbent cores 11; And back-sheet component 15, described back-sheet component 15 covers absorbent cores 11 from the non-skin side of core 11 and becomes the outside of absorbent main body 10.It should be pointed out that this absorbent cores 11 can comprise such as super absorbent polymer and, as liquid absorbent particulates, maybe can comprise the liquid absorptive material outside liquidabsorbing fibres and liquid absorbent particulates.In addition, absorbent cores 11 can be covered by the liquid permeability sheet material (not shown) of such as thin paper.
Surficial sheets component 13 is such as the non-woven fabrics of the liquid permeability that planar dimension is larger than absorbent cores 11.In addition, as shown in Figure 5 B, back-sheet component 15 is also the sheet material that planar dimension is larger than absorbent cores 11, and as the example, can provide and have double-deck sheet material 15, wherein the leakproof sheet material 15a of such as polyethylene or polyacrylic opaque liquid and the outer sheet 15b of such as non-woven fabrics fits each other.Then, under the state that absorbent cores 11 is folded between back-sheet component 15 and surficial sheets component 13, the leakproof sheet material 15a of back-sheet component 15 and similar frame sentenced by surficial sheets component 13 mode from the four limits part outwardly of absorbent cores 11 are fitted.Roughly form absorbent main body 10 by this way.
It is pointed out that in some cases, as shown in Fig. 2, Fig. 3, Fig. 5 B, rivel LG around so-called leakage-proof turnup LSG and leg can be formed by outer sheet 15b.Leakage-proof turnup LSG is the leakproof wall portion LSG of each end portion office being in a lateral direction arranged in surficial sheets component 13 with raised state.On the other hand, around leg, rivel LG is the scalable part LG formed at each leg circumferential openings part 1HL of diaper 1,1HL place.When describing such outer sheet 15b in detail, first, as shown in Figure 5 B, the amount that the size in a lateral direction of outer sheet 15b is enough greatly than the size of leakproof sheet material 15a.In other words, outer sheet 15b significantly gives prominence to from the both sides in a lateral direction of leakproof sheet material 15a in a lateral direction.Then, the center side that this ledge 15bf utilizes the position of the end sections 10es in a lateral direction of absorbent main body 10 to turn back in a lateral direction as folding position, further, the elastic component 17 of such as elastica is fixed near position of turning back in a longitudinal direction under the extension state of longitudinal direction.Therefore, rivel LG around above-mentioned leg is formed.In addition, the part 15bg that turns back extends to center side in a lateral direction further, and joins described end sections in the position of the end sections in a lateral direction of covering surfaces sheet element 13.Then, the part joining this end sections to is used as the base end part LSGb of leakage-proof turnup LSG, in other words, from this base end part LSGb in a lateral direction further tip side part can be used as free end portion LSGf and erect from surficial sheets component 13.In addition, in the top ends office of free end portion LSGf, the elastic component 18 of such as elastica is fixed in a longitudinal direction under the extension state of longitudinal direction.Therefore, this absorbent main body 10 bends towards longitudinal direction due to elastic component 18 contraction in a longitudinal direction, to allow described surficial sheets component 13 side to become inner circumferential side, and when absorbent main body 10 bends by this way, free end portion LSGf utilizes the contractility applied from elastic component 18 shrink in a longitudinal direction and erect from surficial sheets component 13.Therefore, free end portion LSGf plays the effect stopping sieve LSG.
Although it is pointed out that not shown in the accompanying drawings, the liquid permeability sheet material of such as thin paper can be used as to be placed between the second sheet material between surficial sheets component 13 and absorbent cores 11 or in some cases between be placed between back-sheet component 15 and absorbent cores 11.
As shown in Figure 3, veutro band member 30a and DLZ component 30b is from rectangular shape during top view and uses the sheet element of flexible sheet material as material of such as non-woven fabrics.At this, as fig. 5 a and fig. 5b, each band member 30a, 30b are by being formed overlapping also joint of two non-woven fabrics 31,32.Band member 30a, 30b respectively middle body 30ac, 30bc place in a lateral direction cover end sections 10ea, 10eb the longitudinal direction of absorbent main body 10 from the non-skin side of absorbent main body 10, middle body 30ac, 30bc of band member 30a, 30b are overlapping with end sections 10ea, 10eb respectively and join described end sections 10ea, 10eb to simultaneously.
It is pointed out that these two non-woven fabrics 31,32 dimensionally can be different.Such as, Fig. 6 illustrates when this configuration along the viewgraph of cross-section that the line VI-VI in Fig. 3 gets as its example view, and this configuration shown in Fig. 6 is also acceptable.Namely, also acceptable is, in figure 6, non-woven fabrics 31,32 has the size on different longitudinal directions, to make the non-woven fabrics 31 of the non-skin side be positioned on thickness direction give prominence to more towards the end side on longitudinal direction than the non-woven fabrics 32 being positioned at skin side.Then, in this case, as shown in Figure 6, be arranged in the non-woven fabrics 31 of non-skin side, from the non-woven fabrics 32 the being positioned at skin side ledge 31f outstanding to longitudinal direction, utilize the position of the end edge be adjacent on the longitudinal direction of the non-woven fabrics 32 being positioned at skin side as position of turning back, the center side of turning back on longitudinal direction.Then, the part 31g that turns back is overlapping with the non-woven fabrics 32 being positioned at skin side and engage.It is pointed out that the available above-mentioned part 31g that turns back of a part of end sections 10ea, 10eb on the longitudinal direction of absorbent main body 10 covers from the skin side of absorbent main body 10 when performing this and turning back.
At this, when absorbent main body 10 is overlapping with middle body 30bc, 30ac of above-mentioned band member 30a, 30b, absorbent main body 10 is arranged to not overlapping with end sections 30ae2,30be2 on the longitudinal direction of band member 30a, 30b, but overlapping with part 30ac2,30bc2, described part 30ac2,30bc2 than end sections 30ae2,30be2 closer to the center side on longitudinal direction.Therefore, end sections 30ae2,30be2 on the longitudinal direction of band member 30a, 30b are that absorbent main body 10 is not along part 30ae2,30be2 that whole length is in a lateral direction zonally overlapping.It is pointed out that these non-overlapped part 30ae2,30be2 become the part (Fig. 2) of the trunk opening 1HB forming diaper 1.Therefore, in part 30ae2,30be2, elastic component 35U described below is arranged continuously in the substantially whole length in a lateral direction of part 30ae2,30be2.In addition, in size La, Lb on those the part 30ae2 do not overlapped in absorbent main body 10, the longitudinal direction of 30be2, the size of DLZ component 30b is greater than the size (Lb>La) of veutro band member 30a in this example.In other words, absorbent main body 10 is arranged closer to veutro band member 30a than DLZ component 30b as a whole.Therefore, stable urine absorption is guaranteed.But the present invention is not limited to this.Such as, above-mentioned magnitude relationship between La, Lb can be put upside down (that is, Lb<La), or above-mentioned size La, Lb can mutually the same (that is, Lb=La).
As shown in Fig. 3, Fig. 5 A and Fig. 5 B, multiple elastic components 35,35 of such as elastica ... along being placed between horizontal direction between two non-woven fabrics 31,32 of being associated with band member 30a, 30b, and engage under the state extended in a lateral direction and be fixed to non-woven fabrics 31,32.By this way, scalability in a lateral direction will be given to described band member 30a, 30b.In addition, so multiple elastic components 35,35 ... to arrange in a longitudinal direction between the spaced mode of tool in a longitudinal direction.It is to be noted, such elastic component 35,35 ... be set to veutro band member 30a and DLZ component 30b respectively, and their basic comprising is substantially mutually the same, except detailed specification difference, such as elastic component 35,35 ... thickness and number and its allocation position in a longitudinal direction.Therefore, hereinafter, as the elastic component 35,35 be included in veutro band member 30a and DLZ component 30b ... representative, only to the elastic component 35,35 in veutro band member 30a ... be described, and omit the elastic component 35,35 in DLZ component 30b ... description.Therefore, in figure 3, the elastic component 35 in DLZ component 30b is shown by the use Reference numeral 35 identical with the elastic component 35 in veutro band member 30a.In addition, this is equally applicable to all formations relevant to DLZ component 30b.Such as, in described hereinafter diagram sheet material 40, colored portion 50 etc., be provided with the Reference numeral identical with the diagram sheet material 40 in veutro band member 30a, colored portion 50 etc., and omit the description to the diagram sheet material 40 relevant to DLZ component 30b, colored portion 50 etc.
In addition, hereinafter, illustrate for the ease of explaining, as shown in Figure 4, band member 30a is divided into three regions AU, AM and AD in a longitudinal direction.Arrange that three regions AU, AM and AD are in a longitudinal direction called as " upper area AU ", " zone line AM " and " lower area AD " in a longitudinal direction respectively from end side towards center side.It is pointed out that as may be seen in fig., all region AU, AM and AD are the belt like shape regions along horizontal direction.
Upper area AU is the part of the trunk opening 1HB forming diaper 1.In addition, region AU is the region whole length in a lateral direction not having at all overlapping absorbance main body 10.In this upper area AU, elastic component 35U (35) arranges continuously and fixes under the state extended in a lateral direction on the substantially whole length from an end of horizontal direction to the other end of region AU.Therefore, scalability is in a lateral direction given to described upper area AU due to elastic component 35U (35) in the substantially whole length in a lateral direction of upper area AU.This scalability becomes the scalability of the trunk opening 1HB of diaper 1.
Zone line AM (corresponding to first area) is overlapping with the central part AMc in a lateral direction of zone line AM and the fixing region of end sections 10ea on the longitudinal direction of absorbent main body 10.More suitably, do not have the part 10n of absorbent cores 11 overlapping with the above-mentioned central part AMc of region AM in absorbent main body 10 and fix.It is pointed out that in this zone line AM, absorbent main body 10 is not overlapping with the part AMe, the AMe that are positioned on central part AMc both sides.
At this, in such zone line AM, elastic component 35M (35) arranges continuously on the substantially whole length from an end of horizontal direction to the other end of region AM, fixing under the state simultaneously extended in a lateral direction.Therefore, scalability is in a lateral direction given to described zone line AM due to elastic component 35M (35) in the substantially whole length in a lateral direction of zone line AM.In addition, in absorbent main body 10, banded colored portion 50 (Fig. 7) is arranged in the part relative with zone line AM, to allow consumer visually to identify the object of the elastic component 35M (35) zone line AM from the non-skin side of diaper 1.This will hereinafter be described.
Overlapping with the central part ADc in a lateral direction of lower area AD and the fixing region of the part 10p of absorbent cores 11 is there is in lower area AD (corresponding to second area) in absorbent main body 10.It is pointed out that in such lower area AD, absorbent main body 10 is not overlapping with the part ADe, the ADe that are positioned on above-mentioned central part ADc both sides.
In addition, in each part ADe, Ade, elastic component 35D (35) arranges continuously on the substantially whole length from an end of horizontal direction to the other end of part ADe, fixing under the state simultaneously extended in a lateral direction.Therefore, scalability is in a lateral direction given to each region ADe, ADe in the substantially whole length in a lateral direction of each region ADe, Ade.
On the other hand, in above-mentioned central part ADc, elastic component 35D (35) discontinuous layout in a lateral direction.More specifically, in this example, the end sections of aforementioned flexible component 35D (35) is positioned in a lateral direction two end sections ADce, ADce places of premise central portion ADc.But, there is no elastic component 35D (35) in the middle body ADcc in a lateral direction of centre portion ADc in the preamble.Therefore, in above-mentioned central part ADc, elastic component 35D (35) discontinuous layout in a lateral direction.Therefore, when not having elastic component 35D (35) in the middle body ADcc of central part ADc, scalability is given to middle body ADcc hardly, therefore suppresses middle body ADcc contraction in a lateral direction.Therefore, because absorbent cores 11 contraction is in a lateral direction also suppressed, prevent from, in core 11, fold occurs, thus the skin side of core 11 keeps smooth substantially.Consequently, effectively can prevent the liquid-absorbent of infringement core 11 and prevent urine from leaking due to fold.
In addition, as shown in Figure 4, the diagram sheet material 40 (corresponding to the second colored portion) being formed with unshowned diagram such as animal is set at the above-mentioned central part ADc place of lower area AD.For reason similar to the above, also can suppress to form fold in this diagram sheet material 40.Therefore, diagram becomes easily in sight.
It is pointed out that in this example, band member 30a is formed by two overlapping non-woven fabrics 31,32, and illustrates and to be placed between sheet material 40 between two overlapping non-woven fabrics 31,32 and to utilize bonding agent etc. fixing, as shown in Figure 5 B.But the present invention is not limited to this.Such as, diagram sheet material 40 can be fixed to the non-skin side of band member 30a and do not put, and can be fixed to the skin side of band member 30a.Incidentally, when illustrating on the skin side being placed between non-woven fabrics 31,32 between sheet material 40 or be fixed to band member 30a, the diagram of diagram sheet material 40 can be seen by non-woven fabrics 31 (32) via the gap between the fiber of the non-woven fabrics 31 (32) be arranged on the non-skin side of band member 30a.By this way, this diagram can visually identify from the non-skin side thickness direction by non-woven fabrics 31 (32).In addition, as the material of such diagram sheet material 40, resin film such as polyethylene film or polypropylene film can be exemplary.But material is not limited to this, as long as sheet material is flexible and illustrates and can be formed on non-skin side.Such as, also non-woven fabrics or woven can be used.
Incidentally, as mentioned above, if the elastic component 35D (35) of discontinuous layout in the lower area AD (Fig. 4) of band member 30a sees in consumer, then consumer can may worry to some extent to the stickiness of diaper.But, can think, if the elastic component 35 arranged continuously in the substantially whole length in a lateral direction of band member 30a is seen by consumer, then can reduce this worry.Such as, in the upper area AU and zone line AM of this example, there is the elastic component 35 (35U, 35M) arranged continuously by this way.Therefore, can think, if elastic component 35U, 35M in upper area AU and zone line AM see in consumer, then can eliminate this worry.
But, white non-woven cloth and white film are respectively used to outer sheet 15b and the leakproof sheet material 15a of the back-sheet component 15 of the non-skin side being used as absorbent main body 10 as in many diapers, in the diaper 1 shown in the example of Fig. 5 A also.In addition, white non-woven cloth 31,32 is for band member 30a, and white, elastic line is used for elastic component 35 (35U, 35M).Therefore, the elastic component 35 (35U, 35M) in the upper area AU and zone line AM of the band member 30a of Fig. 4 becomes and is difficult to find out as sematic color, is difficult to the existence identifying elastic component for consumers.
In the present embodiment, the object of the elastic component 35M (35) of the zone line AM (Fig. 4) of band member 30a is identified in for the ease of the non-skin side visually from diaper 1, as shown in Figure 5A, in the absorbent main body 10 of locating closer to the skin side on thickness direction than elastic component 35M (35), corresponding to the part of above-mentioned zone line AM by with the color beyond white, thus make colored portion 50 correspond to described zone line AM to be formed.By this way, just colored portion 50 (such as with reference to Fig. 7) can be shown as the background image of the elastic component 35M (35) being arranged in zone line AM.Consequently, the visuality of the elastic component 35M (35) in zone line AM is improved.Detailed description will be provided below.
Fig. 7 is the schematic enlarged view of the veutro band member 30a when observing from the non-skin side of diaper 1.
In this example, as shown in Fig. 7 and Fig. 5 A, colored portion 50 (corresponding to the first colored portion) is arranged in the part place (dash area with reference in Fig. 7) relative with zone line AM in the non-skin side of the leakproof sheet material 15a of the back-sheet component 15 with absorbent main body 10.Therefore, as shown in Figure 7, when observing elastic component 35M (35) in zone line AM from the non-skin side of diaper 1, elastic component 35M seems overlapping with colored portion 50 (dash area in Fig. 7).Therefore, colored portion 50 is used as the background image of above-mentioned elastic component 35M, and elastic component 35M can see from the non-skin side of diaper 1.Consequently, visually identify that the state that elastic component 35M arranges in a lateral direction continuously becomes easy for consumers.
In addition, as shown in Figure 7, colored portion 50 is formed along horizontal direction with belt like shape.Specifically, colored portion 50 is formed with belt like shape in the whole length in a lateral direction of leakproof sheet material 15a (Fig. 5 A).In addition, as shown in Figure 7, colored portion 50 size in a longitudinal direction corresponds to zone line AM.Therefore, the visuality for all (Fig. 7 is three) elastic component 35M, 35M, the 35M being arranged in zone line AM strengthens.In addition, as from above-mentioned being understood that, in this example of Fig. 5 A, because colored portion 50 is arranged continuously in the whole length in a lateral direction of leakproof sheet material 15a, can make visually positively to identify that elastic component 35M is continuous print state in a lateral direction.But colored portion 50 can be elastic component 35M, 35M of being arranged in zone line AM ... in the background image of at least one elastic component 35M.Therefore, in some cases, colored portion 50 can be formed be less than the planar dimension of zone line AM, and in other words, colored portion 50 can in zone line AM.
Incidentally, in this example of Fig. 5 A, the sheet element of locating closer to the non-skin side on thickness direction compared with the leakproof sheet material 15a being furnished with colored portion 50 is two components, and they are outer sheet 15b and the band member 30a of the back-sheet component 15 of absorbent main body 10.These outer sheet 15b and band member 30a are made up of non-woven fabrics.Therefore, the colored portion 50 of leakproof sheet material 15a can the mode seen by these outer sheet 15b and band member 30a of colored portion 50 visually can be identified from the non-skin side of diaper 1 at least slightly.Therefore, the colored portion 50 of leakproof sheet material 15a can play the effect of the background image as elastic component 35M effectively.
In addition, in this example of Fig. 7, diagram sheet material 40 is arranged in the lower area AD of band member 30a, is not namely arranged in zone line AM.Therefore, when observing from the non-skin side of diaper 1, effectively prevent diagram sheet material 40 overlapping with colored portion 50.Therefore, can effectively prevent from colored portion 50 from becoming visually to be difficult to identify from non-skin side.
In addition, the state that diagram sheet material 40 is not arranged in zone line AM and colored portion 50 is arranged in zone line AM as mentioned above can be stated in another way as follows.That is, " when observing from the non-skin side of diaper 1, colored portion 50 comprises not overlapping with diagram sheet material 40 part 50n ".Then, in this case, when colored portion 50 is observed from non-skin side in an identical manner, the elastic component 35M of zone line AM is overlapping with the part 50n of not overlapping with diagram sheet material 40 in colored portion 50.Therefore, it is possible to effectively prevent the elastic component 35M due to substantially whole length in a lateral direction being arranged and in diagram sheet material 40, fold occur.Therefore, the diagram illustrating sheet material 40 can be more easily in sight.
In addition, in this example, owing to forming the outer sheet 15b of back-sheet component 15 of absorbent main body 10 and leakproof sheet material 15a, elastic component 35 (35U, 35M, 35D) be white with described band member 30a (30b), as the example being different from white color, blue for colored portion 50.But the present invention is not limited to this.Such as, redness or green can be used, and other color outside those colors can be selected.In other words, the optional color beyond white can be selected.It is pointed out that when at least one in outer sheet 15b, leakproof sheet material 15a, elastic component 35 and band member 30a (30b) has the color beyond white, according to the combination of these colors, suitably select the color of colored portion 50.That is, the color of colored portion 50 is selected to the color emphasizing elastic component 35M (35) when observing described elastic component 35M (35) from the non-skin side of diaper 1.Such as, the color of colored portion 50 can be configured to the color of the color of the both sides being different from elastic component 35M (35) and leakproof sheet material 15a, and can be configured to be different from the color of each color of described elastic component 35M (35), leakproof sheet material 15a and outer sheet 15b.
Incidentally, same color as herein described is defined as follows.First, at this, all colours can represent as prerequisite by the combination of the analog value of brightness, tone and saturation, and described analog value is selected from 0 ° to 360 °.Then, under this prerequisite, by determining the brightness of their colors, the analog value of tone and saturation compares respectively between two kinds of colors.As the result compared, when the analog value of a kind of brightness of color, tone and saturation be included in respectively the brightness of another kind of color, tone and saturation analog value ± 5 ° scope in time, then think that they have " identical color ", even and if when brightness, tone and saturation one of value not included in the scope of ± 5 ° time, they are considered to have " color different from each other ".
In addition, in the example of Fig. 5 A and Fig. 7, colored portion 50 is passed through directly painted on the non-skin side of leakproof sheet material 15a and is formed.But the present invention is not limited to this.Such as, colored portion 50 is arranged by another color sheet being joined to leakproof sheet material 15a.In addition, colored portion 50 can be formed on outer sheet 15b instead of on leakproof sheet material 15a.It is pointed out that the formation method as colored portion 50 in this case, the method identical with leakproof sheet material 15a situation can be adopted.That is, colored portion 50 is by directly painted on the non-skin side of outer sheet 15b and formed, or colored portion 50 is formed by joining another color sheet to outer sheet 15b.
Incidentally, as understood from the above description, colored portion 50 is set to the part relative with zone line AM in absorbent main body 10.That is, as shown in Figure 7, colored portion 50 is set to the part 10n not having absorbent cores 11 in absorbent main body 10.On the other hand, the elastic component 35M (35) emphasized by colored portion 50 arranged continuously in a lateral direction is also set to zone line AM.Then, such elastic component 35M (35) makes absorbent main body 10 shrink in a lateral direction, and the zone line AM arranging elastic component 35M (35) comprises part 10n, in absorbent main body 10, absorbent cores 11 is not had, as understood from description above in part 10n.Therefore, it is possible to effectively suppress because these elastic components 35M (35) produces fold in absorbent cores 11, thus the skin side of absorbent cores 11 is made easily to keep general planar.This also contributes to the liquid-absorbent preventing from damaging absorbent cores 11 effectively.
Other embodiment
Although the present invention is described in conjunction with the embodiments, should be understood that, providing above-described embodiment is to easily understand the present invention, but is not used for explaining the present invention in restricted mode.It is to be further understood that without departing from the spirit of the invention, changes and improvements can be carried out to the present invention, and the present invention also comprises their equivalent naturally.Such as, modification as described below is possible.
Above-described embodiment is the exemplary embodiment of following situation, and the colored portion 50 wherein as an example of the first colored portion is set to part relative with the zone line AM of veutro band member 30a in absorbent main body 10.But the present invention is not limited to this.That is, similar colored portion 50 can be set to part relative with the zone line AM of DLZ component 30b in the absorbent main body 10 of Fig. 4.By this way, be arranged in the elastic component 35M (35) of the zone line AM of DLZ component 30b, that is, the elastic component 35M (35) the substantially whole length in a lateral direction of zone line AM arranged continuously visually positively can be identified by consumer.This will relax the worry of consumer in diaper 1 landing after defecating.
In the foregoing embodiments, in order to be reduced in described band member 30a (30b) scalability of the central part ADc in a lateral direction of the lower area AD being provided with diagram sheet material 40, elastic component 35D (35) the discontinuous layout of central part ADc.Then, as an example of these discontinuous elastic component 35D, as shown in Figure 7, following configuration is exemplary, its elastic member 35M (35) is present in a lateral direction two end sections ADce of central part ADc, in ADce, and elastic component 35D (35) is not stored in the middle body ADcc in a lateral direction of central part ADc.But the present invention is not limited to this.
In other words, if elastic component 35D is discontinuous be arranged in central part ADc to reduce the scalability of the central part ADc of lower area AD, then elastic component 35D also may reside in the middle body ADcc of this central part ADc.Fig. 8 is the diagrammatic plan view for the example that this formation is shown.It is pointed out that Fig. 8 illustrates that the non-woven fabrics 31 of the non-skin side of band member 30a is removed and makes elastic component 35 (35U, 35M, 35D) expose outside state.In example in fig. 8, the elastic component 35D being arranged in middle body ADcc has been subdivided and has cut.If segmented under the state of cutting, scalability be not given to middle body ADcc by elastic component 35D substantially.Therefore, the elastic component 35D that such segmentation is cut can be present in middle body ADcc.Segment the length of elastic component 35D of cutting such as to be greater than 0 millimeter and to be less than or equal to 5 millimeters, be less than or equal to 3 millimeters more preferably greater than 0 millimeter.But if there is the elastic component 35D segmenting and cut, then degraded appearance, therefore preferably elastic component 35D does not exist (Fig. 7) in middle body ADcc.
In the above-described embodiments, discontinuous layout in the central part ADc in a lateral direction of elastic component 35D (35) lower area AD in the diagram.But the present invention is not limited to this.Such as, elastic component 35D (35) can not be arranged in central part ADc.That is, in the example of above-mentioned Fig. 4, the end sections of elastic component 35D (35) is arranged in the position of the respective end part ADce in a lateral direction of central part ADc, ADce.But this end sections of elastic component 35D (35) can not be arranged on the position of the end sections ADce of central part ADc.
