The trunk has: a first ruled line which is formed in a circumferential direction of the trunk to be folded to a center side of the trunk and fitted to a peripheral edge part of the flange part; and a second ruled line which is constituted with one ridge-folding line and two right and left valley-like bent lines, which are formed at a prescribed position, as one set, and in which two or more sets are equally formed along the circumferential direction of the peripheral edge part. The peripheral edge part is roughly circular when viewed in the height direction of the trunk. The other end of the trunk is bent along the first and second ruled lines and is fitted to the peripheral edge part while forming pleats folded in an outer face of the other end of the trunk on the peripheral edge part.SELECTED DRAWING: Figure 1
