Claims

[Scope of Claim for Utility Model Registration] A thin bowl body 1 and a large diameter hole 2a of the plate body to be closed are formed into an arc shape with approximately the same outer diameter and thickness, and are arranged at the center of the inner surface of the bowl body 1 between the two. A plurality of arc-shaped plates 3 are arranged in succession on the same circumference with a gap 4 between them.
. . . The small diameter hole 2b of the plate body to be closed is curved into an arc having an outer diameter approximately equal to that, and a gap approximately equal to the gap 4' is provided between the outer surfaces 3a of each arcuate plate 3. The same number of curved plates 5 as the arc-shaped plates 3 are connected on the same circumference coaxially with the arc-shaped plates 3, and the curved plates 5 have the same number as the arc-shaped plates 3.
Engagement protrusions 6 protruding from key points on the outer surface of each curved plate 5 so as to be parallel to each other with a gap approximately equal to the thickness of the plate.
...and the base end is fixed in the gap 4 on the inner surface of the bowl body 1 so as to be parallel to the axis of the arcuate plate 3, and the outer surface is on the same circumferential surface as the outer circumferential surface of the arcuate plate 3. At the free end of the base piece 7a, the length in the axial direction is almost equal to the thickness of the plate, and the inner surface is on the inner circumferential surface between the outer circumferential surface of the arc-shaped plate 3 and the outer circumferential surface of the curved plate 5,
an engaging hook 7 that faces in the radial direction, has an inner surface on an extension surface of the outer surface 3a of the arc-shaped plate 3, and has an outer surface connected with a hook piece 7b that obliquely intersects with the radial edge of the inner surface; A blockage plug that is integrally molded with materials.
