Abstract
PURPOSE:To erase a moisture infiltration due to diffusion and to maintain the inside of an enclosure at low humidity, by providing a valve to keep a pressure in the enclosure and the pressure of atmosphere to an equilibrium state to an atmosphere infiltration route to execute ventilation between the inside of the enclosure and the atmosphere. CONSTITUTION:To the atmosphere infiltration route, valves 10, 11 are provided to be opened by breathing operation and to completely disconnect the inside and outside of an enclosure 3 while being closed in other cased. Namely, the valves 10, 11 are opened by the pressure difference of the inside and outside of the enclosure 3 and have the breathing operation so as to be closed when the pressure difference is erased. When the bulbes are closed, the enclosure 3 goes to a completely closed condition. Thus, the infiltration of the moisture occurred by the diffusion from the atmosphere, is erased and the inside of the enclosure 3 is maintained at the low humidity.
