Abstract

A shutter device includes a pair of support frames spaced in parallel with a predetermined distance therebetween, and a shutter arranged between the support frames. The support frames support both the right and the left shutter flanks of the shutter so as to allow the shutter to reciprocate along a longitudinal direction of the support frames. A weatherstrip is inserted between a side in each flank of the shutter and an opposing face of corresponding one of the support frames facing the side. The weatherstrip includes a long base material fixed to the support frame, a plurality of threads raised on the base material, and film member provided on the base material. The film member has a higher rigidity than the treads, and the height of the film member in a direction towards the opposing face of the support frame is lower than that of the treads. When the shutter is subjected to a strong external force, effective suppression of chattering of the shutter is achieved while at the same time reducing sliding resistance of the shutter.
