Shutter

A shutter comprising:

• a pair of guide rails spaced apart in a first direction extending in a horizontal direction;
• a guide path extending in an extension direction of the pair of guide rails at a position between the pair of guide rails in the first direction;
• and
• an opening and closing body configured to move along the guide path,
• wherein:
• the opening and closing body comprises a plurality of rod-shaped members extending in the first direction and arranged at an interval in a guide direction extending along the guide path, and a plurality of coupling members disposed in the guide direction and configured to couple the plurality of rod-shaped members,
• opposite end portions of each of the plurality of rod-shaped members in the first direction are respectively guided by the pair of guide rails in such a manner as to be movable in the guide direction,
• each of the coupling members comprises a body part extending in a planar manner along the guide direction, a pair of fitting parts that are disposed at the body part, spaced apart in the guide direction, and configured to be fitted to a coupling target pair of rod-shaped members that are adjacent to each other in the guide direction, and one or more reinforcing ribs protruding from the body part from a front surface side or a back surface side and extending in a planar manner along the guide direction,
• opposite end walls of the body part in the first direction protrude from the back surface side in a planar manner, and
• each of the fitting parts comprises at least one cover part having flexibility and configured to cover a range of an outer circumferential surface of each rod-shaped member of the coupling target pair of rod-shaped members, the range being smaller than a circumference of the outer circumferential surface and larger than half the circumference as viewed in the first direction.
