That is, in a state where the storage portion 11 and the bag portion 12 are doubled, the inner surface of the storage portion 11 and the outer surface of the bag portion 12 are in contact with each other, and the inner surface of the bag portion 12 is filled with the storage portion 11. It is the part that an object comes into contact with when it is hit. Note that the bag portion 12 does not have to be spread out in a bag-like shape inside the storage portion 11 and not overlapped. It may be stored.

The bag portion 12 is connected to the storage portion 11. More specifically, the outer peripheral edge of the opening portion 13 of the bag portion 12 is aligned with the inner peripheral edge of the opening portion 14 of the storage portion 11 by, for example, sewing. The bag portion 12 is connected (bonded) to the storage portion 11 by bonding with an adhesive, fusion bonding, or the like. The method of connection is not limited to these. At this time, since only the edge of the outer circumference of the opening 13 of the bag portion 12 is connected to the storage portion 11, the bottom portion 15 of the bag portion 12 is pulled upward from the opening portion 14 of the storage portion 11 as shown in FIG. becomes possible.
