To provide a guiding structure of a shutter curtain and a guide member easily fitted in a shutter storing part, and restraining contact noise in opening and closing the shutter curtain, thereby improving fitting workability and reducing contact noise.

This guiding structure of a shutter curtain is provided in a connecting part between a shutter storing part 1 and a guide rail 7 to guide the entering and leaving of the shutter curtain. The guiding structure includes: a bracket 3 constituting the side of the shutter storing part 1; and the guide member 5 having a fit-in part 27 fitted to the bracket 3 in which the upper end 7a of the guide rail 7 is inserted, and a pair of curved guide pieces 19, 21 confronting with the surface and back of the shutter curtain whose gap is gradually decreased as it goes toward the guide rail 7 to be substantially equal to the curtain holding gap (d) of the guide rail 7. At least the curved guide pieces 19, 21 of the guide member 5 are formed of synthetic resin.
