PROBLEM TO BE SOLVED: To provide an inside-outside air pressure difference eliminator for surely eliminating a pressure difference, even if a driving spring is not used for setting a timing lag (a required clearance) for a pressing member.SOLUTION: A driving member 51 is composed of a slider 52 operated by pressing force of operation pieces 23 and 35 and a cooperation lever 53 journaled by a support shaft 55 existing in a position separate by a predetermined interval from the operation pieces of an operation member so as to cooperate with the slider, and the pressing member is also composed of a sliding control body 62 for sliding to the front 8a side of a lock box 8 against energization force of energization means 67 via the driving member and a swing type pressing body 65 connected via linking means 64 including a frame-shaped connection projection piece 64a having a clearance for a timing lag in a tip part of this sliding control body and having an engaging projection tip part 65b journaled via a vertical shaft 66 and also always projecting from the front 8a to its tip part side.SELECTED DRAWING: Figure 4 |
