ELASTIC GAS SEALING MATERIAL AND HOUSING

PROBLEM TO BE SOLVED: To provide an in-housing holding device which can prevent an apparatus in a housing or the housing itself from rusting by expanding an inside of the housing to push out air in the housing, thereby reducing the volume of the air which is directly brought into contact with the apparatus in the housing.SOLUTION: An in-housing holding device according to one embodiment is an elastic gas sealing material which is made of an elastic material and in which gas of molecules larger than a gap of films is sealed. A moisture absorption material is sealed in an inside of the elastic gas sealing material, and at least a part of the elastic gas sealing material is made of a water permeable material.SELECTED DRAWING: Figure 1 【課題】本発明の実施形態が解決しようとする課題は、筐体の中で膨らませ筐体内の空気を押し出すことで、筐体内機器に直接触れる空気の体積を減らし、筐体内機器や筐体自体が錆びることを防止する筐体内保持装置を提供することである。【解決手段】実施形態の筐体内保持装置は、伸縮性のある素材で作られ、膜の隙間より大きな分子の気体が封入される伸縮性気体封入材であって、伸縮性気体封入材の内部に吸湿性のある材料が封入され、伸縮性気体封入材の少なくとも一部に透水性のある材料で作られる伸縮性気体封入材。【選択図】 図１
