In addition, this is achieved by providing a bag provided with a fastening portion 4 for maintaining the retracted state of the elastic portion 3 on the side wall portions 1 and 2.

The bag has an elastic portion 3 between the side walls 1 and 2 facing each other, and the thickness can be changed by expanding and contracting the elastic portion 3. When the baggage is small, the bag can be used in a state where the elastic portion 3 is maintained in the contracted state by the fastening portion 4, and when the baggage increases, the elastic portion 3 can be extended to increase the volume.

The elastic portion 3 can be formed by connecting a rigid material to each other via an appropriate hinge so as to be freely rotatable. However, when the elastic portion 3 is formed of a soft material, the hinge and the like are not required. , The structure becomes simple. In this case, claim 2
As described in the above, it is desirable to provide a rigid holding portion 5 for stiffening the bottom of the elastic portion 3 in the extended state. The rigid holding portion 5 may be made of a hard plate material held on one side or a stretchable pipe. In the present specification, “soft” refers to a material that is flexible enough to be foldable, and “hard” refers to a material that cannot be folded and has sufficient hardness to maintain its outer shape. .

The side walls 1 and 2 disposed on both sides of the expansion / contraction section 3 can be made of either a hard material or a soft material. The portion 1 can be formed of a hard material, and the side wall portion 2 formed in a flat shape can be formed of a soft material. That is, the invention according to claim 3 includes a side wall 1 having a tray shape,
When the expansion / contraction part 3 is in a contracted state, the open part of the hard side wall part 1 has a soft side wall. The state is closed by the unit 2. By forming one of the side wall portions 1 from a hard material, the shape retention of the entire bag is increased, and the luggage stored in the hard side wall portion 1 can be protected from impact.
