PROBLEM TO BE SOLVED: To provide a shutter apparatus with a locking device, capable of reducing a risk that smooth opening-closing movement of a shutter curtain is affected by a latch-receiving part of a latch-receiving member.SOLUTION: In a shutter curtain 1 guided by a guide rail 4 and moving for opening-closing, a latch member 21 is arranged so as to be able to advance and retreat. The latch member 21 is engageable with and disengageable from a latch-receiving part 61 of a latch-receiving member 22 attached to the guide rail 4. The latch member 21 advancing from the shutter curtain 1 projects to the shutter curtain 1 side and locks to the latch-receiving part 61 provided inside the guide rail 4, and thus the shutter curtain 1 is locked. Inside the guide rail 4, a projection 62 projected to the shutter curtain 1 side is provided so as to be deviated from the latch-receiving part 61 in the opening-closing movement direction of the shutter curtain 1, and the projection amount of the projection 62 is larger than that of the latch-receiving part 61. |
