<p>PURPOSE:To ensure and simplify the sealing of a sealed chamber without considering the reactivity or the like with its stored object by inserting a liquid-tight or airtight elastic enclosing body into a through hole section and providing a female screw and a male screw mated together in this elastic enclosing body. CONSTITUTION:A male screw 106 or a female screw 105 is coupled and tightened to the mated female screw 105 or the male screw 106 in an elastic envelope body 102 through an opening section 103 from outside the opening section 103 of the elastic enclosing body 102. An annular bulge section 109 bulged annularly outward is generated between the flange section 104 of the elastic enclosing body 102 and the installation section of the female screw 105 or the male screw 106 provided in this elastic enclosing body 102. The periphery section of the through hole section 101 of the sealed chamber is pinched airtightly or liquid-tightly between this bulge section 109 and the flange section 104, and the through hole section 101 of the sealed chamber 100 is sealed by the elastic enclosing body 102. Accordingly, sealing is performed stably without directly contacting the stored object.</p> |
