PROBLEM TO BE SOLVED: To enable preservation of such oxidation-phobic substances easily deteriorated by oxidation represented by fuel in a fuel tank, in an inactive atmosphere, without hindering mountability to a vehicle, and without causing deterioration in fuel efficiency.SOLUTION: An oxidation inhibition mechanism keeps insides of storage parts in an inactive atmosphere, by supplying nitrogen-rich air 5 to the storage parts (a fuel tank 2, a reservoir tank 13, a transmission casing 14 and a differential casing 15) for storing oxidation-phobic substances easily deteriorated by the oxidation in a vehicle, is aimed at the vehicle mounted with an air tank 1 for storing compressed air as an operation source of a pneumatic operation device, and is constituted so that parts between the air tank 1 and the storage parts are connected by an air feeding pipe 3 and the nitrogen-rich air 5 generated by a film separation type nitrogen gas generator 4 can be supplied to the storage parts by interposing the film separation type nitrogen gas generator 4 of using a nitrogen-rich film in the middle of the air feeding pipe 3. |
