Fig. 4 is the figure that schematically shows the state in the underwear that absorbent commodity 1 is worn on.Fig. 5 is the cutaway view of B-B section shown in Figure 4.The external force of being brought by the action of wearer etc. towards the inboard from the width outside acts on and is configured in the zone that near the alar part the portion 43 clips between hipbone.
Alar part 43 be when the lower limb of wearer closes up etc. from the width outside towards the part that receives power medially.Aileron portion 60 is configured in the position of leaning on the rear than alar part 43, when the power that receives from the width outside towards the inboard, receives from the front side at alar part 43 places towards the power at rear.
At this moment, owing in aileron portion 60, be formed with the 1st narrowing portion 61 and the 2nd narrowing portion 62, therefore, aileron portion 60 is that the basic point distortion absorbs the power from the front side with the 1st narrowing portion 61 and the 2nd narrowing portion 62.For example, the power that applies from alar part 43 sides is absorbed by the 1st narrowing portion 61, can make to the power of leaning on the rear to propagate than the 1st narrowing portion 61 to reduce.Thus, suppress to propagate to whole aileron portion, thereby can prevent that whole aileron portion from producing fold, fold from the power of front side.
In addition, the Breadth Maximum position configuration of the 1st aileron portion the 63, the 2nd aileron 64 and the 3rd aileron portion 65 is in the position of leaning on rear side than the center of the length direction of each aileron portion.For example, when the Breadth Maximum position of each aileron portion was positioned at the front side, only the front part of aileron portion was crooked partly, can not come absorbing power with each aileron portion integral body.
Yet, be positioned at the position of leaning on rear side than the center of the fore-and-aft direction of each aileron portion through the Breadth Maximum position that makes each aileron portion, can be in each aileron portion absorbing power integrally, can suppress to produce partly fold.
In addition, the 2nd Breadth Maximum position is positioned at the position of leaning on the width outside than the 1st Breadth Maximum position, and the 3rd Breadth Maximum position is positioned at the position of leaning on the width outside than the 2nd Breadth Maximum position.That is the position in the width outside is leaned in the Breadth Maximum position that the Breadth Maximum position that, is positioned at the aileron portion at rear is positioned at than is positioned at the aileron portion in the place ahead.Thus, can utilize the aileron portion in the place ahead to absorb the power of propagating from the place ahead, then, utilize the aileron portion at rear to absorb.That is absorbing power by stages.In addition, therefore aileron portion, can dispose along underwear because width becomes big along with going towards the rear.
In aileron portion 60, be formed with the depressed part 70 that on thickness direction T, caves in.As shown in Figure 3, in depressed part 70, the lateral plate 41, intermediate 35 and the back sheet 20 that are used to constitute surface patch are compressed on thickness direction.Depressed part 70 comprises: the 1st depressed part 71, and its back medial end 43RI from alar part 43 rearward extends; The 2nd depressed part 72, it is from the 1st depressed part 71 branches and arrive the 1st narrowing portion 61; The 3rd depressed part 73, it is from the 1st depressed part 71 branches and arrive the 2nd narrowing portion 62; The 4th depressed part 74, its from the 1st depressed part 71 branches, and arrive near the 3rd the most significantly the putting the 65WM of the width outside of the 3rd aileron portion 65 that is positioned at.
Depressed part is compressed at thickness direction towards back sheet side ground from the surface patch side.Form depressed part 70 through compressing towards back sheet side ground, when forming depressed part, can suppress to break by the back sheet that film constitutes from the surface patch side.In this embodiment, compress towards back sheet side ground from lateral plate 41 sides that are used to constitute surface patch.
The 2nd depressed part the 72, the 3rd depressed part 73 and the 4th depressed part 40 along with going towards the rear in the width side direction width outside extend.Through forming depressed part with the mode that extend in the side direction width outside in the width along with going towards the rear, because depressed part is along the action direction of power, therefore, depressed part becomes folding starting point, and aileron portion is folding by naturally.Thus, aileron portion 60 still all is not easy to be fit to underwear to health not difficultly.Thereby, be difficult to produce chaotic fold in aileron portion, can produce the distortion that does not have sense of discomfort, can access happy wearing sense.
