Abstract

PURPOSE: To prevent damage of reinforced glass, by covering the outer circumference of reinforced glass attached to the viewing window with an elastic packing.
CONSTITUTION: The outer sides of reinforced glass 306 inserted between the main body 301 and cover flange 302 and clamped with bolt 303 and nut 304 are rounded and covered with rubber or similar elastic packing 305. When load is applied to the packing 305 due to the tightening torque of bolt 303 and nut 304, the packing 305 shrinks due to elasticity to produce a reaction, which causes the main body 301 and the packing 305, the cover flange 302 and the packing 305, and the reinforced glass 306 and the packing 305 to tightly contact with each other respectively, thereby increasing the airtightness. Meanwhile, since the load is not directly applied to the reinforced glass 306, its damage may be prevented.
