[0003]
Further, in order to be suitably worn by a pregnant woman whose waist is inflated, as shown in FIG. 7, a knitted fabric continuously knitted in a cylindrical shape by a circular knitting machine is used, and this knitted fabric is partially knitted. The portion 111 corresponding to the abdomen is partitioned into a substantially semicircular shape, and the partition portion 111 has a three-dimensional bulge and has a knitted structure with a large elongation, while the left and right bulged portions 113 and 114 are Are provided with knitted fabrics 115 and 116 having small stretches (see Patent Document 2).

[Problems to be solved by the invention]
In general, when a pregnant woman is in the middle of the second trimester or later, as shown in FIG. 5, the abdomen bulges forward, the abdominal wall increases, and the lumbar lordosis increases. Therefore, the pregnancy uterus comes to protrude forward at the upper edge of the pubic bone, which is undesirable for both the mother and the fetus. Therefore, after the second trimester of pregnancy, the lumbar vertebral anterior degree must be prevented from increasing. In the underwear of Patent Document 1 and Patent Document 2 described above, although the effect of preventing back pain and preventing a burden on the abdomen is recognized, it was not devised in terms of keeping the lumbar lordosis small, Even when worn, the effect of reducing the lumbar lordosis was not obtained.
[0007]
The present invention has been made paying attention to the above problems, and an object thereof is to provide a maternity pant capable of preventing the posture of a pregnant woman from changing to an unfavorable posture even after the middle stage of pregnancy. .
[0008]

Here, as shown in FIGS. 4 and 5, the “pelvic inclination angle” means an angle formed with the pelvic upper edge line B with respect to the horizontal axis A, and the “change in pelvic inclination angle” means FIG. The change of the pelvic inclination angle from the state where the pants for pregnant women are not used (the pelvic inclination angle α1) to the case where the pants for pregnant women of the embodiment shown in FIG. 4 is attached (the pelvic inclination angle α2).
[0020]
