Claims

[Claims for Utility Model Registration] A mechanism for a shutter 16 that is provided in an opening 3 and opens and closes by reciprocating the opening surface of the opening 3 in a parallel direction, the shutter 16 being placed opposite the opening 3. A sliding means 18 is slidably engaged with a slit 17 provided in parallel to the orthogonal direction of the side edge 3', and the end 1 of the first lever 19 is engaged with the sliding means 18.
9a is rotatably locked, and the other end 19b
is rotatably locked to the end 20a of the second lever 20, and the locking portion 2 of the first and second levers 19, 20
2 in a direction perpendicular to the opening surface, the other end 20b of the second lever 20 can be freely rotated to a predetermined position where the shutter 16 can be opened and closed in the opening 3. A shutter mechanism characterized by being locked.
