Abstract

PURPOSE:To improve the strength of an overall shutter base of its own by integrally forming a thicker part on the surface of the shutter base in which a blade sector is arranged and in any areas except an area in which the arm of the blade sector traveling the surface of the base travels. CONSTITUTION:With a caulked part between a main arm 11a and a divided blade 11d in the rear blade sector, a caulking pad 11f for caulking is formed on the shutter base (lower side in illustration). The protruding amount of the pad 11f has to be set an allowance on the surface of the shutter base in its thickness direction, and a greater allowance in the thickness direction is provided by taking account of safety. Therefore, the thicker part is placed so as to stick out the allowance in the thickness direction and so as to lie in any areas except for the area in which the main arm 11a and a sub-arm 11d in the rear blade sector travel, whereby the thickness of the overall shutter never increases.
