PROBLEM TO BE SOLVED: To provide a unitized lower end sealing device to be used in a pair of panel with a same width of a sliding shutter. SOLUTION: The accommodation base 41 of a pair of arms 4 is respectively accommodated in a lifting frame 3 to fix both ends of a leaf spring 7 to each rising part 42 and the rising part 42 is fixed to one pair of end slide rods 5. Furthermore, a working projection 6 is fixed to the panel 21 side of the end slide rods 5, and a coil spring 8 is arranged between the rising part 42 and the stopper 74 of the leaf spring 7 to be a unit of the lower end sealing device B. While being mounted to the bottom rail 24 through an end cap, the working projection 6 projects/retracts to operate the leaf spring 7, and a lifting frame support member 73 in the middle lifts the lifting frame 3 in the bottom rail 24. When closing the panel 21, the air-tightness between the panel and the lower frame 1b is secured through the contact with the downward inclined sealing beat 31 of the lifting frame 3. When opening/closing the panel, the sealing beat 31 is contact-released for smooth opening/closing of the panel. COPYRIGHT: (C)2011,JPO&INPIT
