<p>PROBLEM TO BE SOLVED: To provide a dustproof guiding device capable of ensuring a high dustproof property. SOLUTION: A pair of seal members 15a and 15b of band shape and having flexibility are disposed to an upper part and an lower part, respectively, along a periphery of an opening 13 formed by an outer package cover 12. A tip of the seal member 15a and a tip of the seal member 15b are overlapped to each other. A movable member 14 attached to a guide object opens the pair of seal members 15a and 15b and moves so as to push aside the seal members 15a and 15b. Since the pair of seal members 15a and 15b are overlapped to each other, a gap between the seal members 15a and 15b is not generated, and an inside of the outer package cover 12 is perfectly sealed. After the movable member 14 passes, the seal members 15a and 15b are restored immediately by their own elasticity, whereby the tips of the seal members 15a and 15b are again overlapped to each other, respectively.</p> |
