Claim:
An enclosure for outdoor equipment, comprising: an airtight main body; and an inside air pressure adjusting mechanisms, wherein said inside air pressure adjusting mechanism comprises: a plate part having a plate in which a hole passing through said plate is formed, a valve seat formed in said hole having a step and a conical shape, and whose diameter is enlarged toward the outside of said airtight main body, a valve shaft part in which a flange is formed at one end and an air pressure receiving surface on which air pressure inside said airtight main body is received is formed at the other end, and said valve shaft part sits on said valve seat such that a place between said valve seat and said valve shaft part can be opened and closed, and said valve shaft part is loosely inserted into said hole of said plate part such that an inside surface of said flange faces said valve seat and a ring shape sealing component is disposed between said inside surface of said flange and said valve seat; and an elastic component, which is disposed at a part of said valve shaft part which sticks out from a rear surface of said plate, makes said valve shaft part sit on said valve seat by pushing the rear surface of said plate such that a place between said plate shaft part and said valve seat can be opened and closed, and said airtight main body comprises: an opening part into which said inside air pressure adjusting mechanism is inserted, wherein said inside air pressure adjusting mechanism is fixed to said opening part of said airtight main body such that said air pressure receiving surface of said valve shaft part faces toward the inside of said airtight main body, wherein said inside air pressure adjusting mechanism is fixed to said airtight main body, and said inside air pressure adjusting mechanism prevents the atmosphere from entering said airtight main body, and exhausts air inside said airtight main body corresponding to a rise of air pressure inside said airtight main body.
