A door shutter is disposed in a device having an opening, and side portions for defining the opening. The other side of the opening extends higher than the one side. Guide grooves are formed along the side portions. The shutter includes main bodies bendable in a sliding direction for opening and closing the opening on the device, and projecting portions projecting from lateral sides of the main bodies in a width direction thereof and slidably engaging the guide grooves. The main body has first and second sides corresponding to the one and the other sides of the device. The wall thickness at the second side is thicker than that at the first side corresponding to the other side to form a substantially uniform surface from the one to the other sides through the main bodies.

What is claimed is: 1. A door shutter comprising: a device including an opening, and side portions for defining the opening having one side and the other side extending higher than the one side, guide grooves formed along the side portions extending substantially parallel to each other without substantial height difference between the two sides, and having curved portions, and a shutter including main bodies bendable in a sliding direction for opening and closing the opening on the device, and projecting portions projecting from lateral sides of the main bodies in a width direction thereof and slidably engaging the guide grooves, said main body having a cover member disposed between the guide grooves substantially parallel thereto, a wall thickness in the width direction, and first and second sides corresponding to the one and the other sides of the device, the wall thickness at the second side being thicker than that at the first side corresponding to the other side to form a substantially uniform surface from the one to the other sides through the main bodies inclined relative to the cover member, wherein said main bodies include elongated rigid pieces arranged along the sliding direction of the shutter with a predetermined space between two rigid pieces and having connecting projections at lateral sides thereof, said rigid pieces being inclined relative to the cover member. 2. A door shutter according to claim 1, wherein said side portions are side walls of a container for forming the device. 3. A door shutter according to claim 1, wherein said device further includes an installation portion having said opening and said side portions. 4. A door shutter according to claim 3, wherein said device further includes a container disposed under the installation portion and having said guide grooves. 5. A door shutter according to claim 1, wherein said opening of the device has a concave forming a holding portion, said curved portion of the guide grooves has a C shape or inverted L along a longitudinal direction of the guide groove, and a line connecting the guide grooves on both sides is substantially horizontal with respect to a bottom face of said concave. 6. A door shutter comprising: a device having an opening, and side portions for defining the opening, guide grooves formed along the side portions, and having curved portions, and a shutter including main bodies bendable in a sliding direction for opening and closing the opening of the device, and projecting portions projecting from lateral sides of the main bodies in a width direction thereof and slidably engaging the guide grooves, said main bodies including elongated rigid pieces arranged along the sliding direction of the shutter with a predetermined space between two rigid pieces and having connecting projections at lateral sides thereof, and rectangular elastic connecting members disposed on back sides of the rigid pieces to enable positioning and having elastic frame portions, said projecting portions being formed by the elastic frame portions where the connecting projections projecting laterally from the rigid pieces are received therein. 7. A door shutter according to claim 6, wherein said connecting members are formed of two members disposed on right and left of the back side of said rigid pieces. 8. A door shutter according to claim 6, wherein each of said connecting members includes piece portions with a number corresponding to that of the rigid pieces, said frame portions respectively provided on said piece portions, and thin-walled portions connecting said piece portions. 9. A door shutter according to claim 8, wherein each of said piece portions has a hole to insert a pin projecting on a back face of said rigid piece, and said thin-walled portion is formed between said piece portions and provided in more than two portions. 10. A door shutter according to claim 1, wherein said main bodies further include rectangular elastic connecting members disposed on back sides of the rigid pieces for connecting the rigid pieces along the sliding direction.
