Document Type and Number:
Japanese Patent JP2014240589
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To surely prevent that a rotating shaft part of one slat out of adjacent two slats falls from a circular cylindrical bearing part of the other slat.SOLUTION: When a support part 1b2 of a connecting protrusion 1b of one slat 1 of a shutter 100 is arranged in an arbitrary position between circumferential both ends 1c1a', 1c1b' of a circular cylindrical bearing part 1c1' of a connecting recess 1c' of the other slat 1', an external peripheral face of a circular cylindrical fall prevention part 1b3 of the slat 1 and an internal peripheral face of a circular cylindrical fall prevention part 1c3' of the slat 1' oppose each other on a plane S1 which connects a center axial line 1b1b of a rotation shaft part 1b1 of the slat 1 and an intermediate position 1c1e' of the circumferential both ends 1c1a', 1c1b' of the circular cylindrical bearing part 1c1' of the slat 1', and at a side opposite to the center axial line 1b1b apart from the intermediate position 1c1e', or an internal peripheral face of the fall prevention part 1b3 and an external peripheral face of the circular cylindrical bearing part 1c1' of the slat 1' oppose each other on the plane S1, and at the position at the side opposite to the intermediate position 1c1e' apart from the center axial line 1b1b.
