- This fluoro rubber includes perfluoro fluoro rubber (FF KM) whose main chain is completely fluorinated, ordinary fluoro rubber (FKM) having a carbon-hydrogen bond in a part of the main chain, and extrusion molding.
- FF KM perfluoro fluoro rubber
- FKM ordinary fluoro rubber
- a possible fluorine-based thermoplastic elastomer is also preferable in terms of heat resistance and low gas generation.
- a groove 80 is formed in the vicinity of the outer edge portion of the bottom member 78 constituting the reticle storage case 74 as a modified example.
- a convex portion 82 is formed at the central portion of the groove 80 in the groove width direction.
- the other configuration of the reticle storage case 74 is the same as the configuration of the reticle storage case according to the first embodiment described above, and a description thereof will be omitted.
- the reticle storage case 74 is made of a resin such as polycarbonate.
- a predetermined pressure acts as a reaction force on the groove side walls 78A and 78A in which the rear end portions of the pressure portions 72A and 72A are opposed to the convex portion 82 in the groove width direction.
