摘要：
A camera shutter has a shutter base plate for pivotally supporting blade groups each constituted by a plurality of blades carried by arms and a thick-walled portion formed on the surface of the shutter base plate that carries the blade groups. The thick-walled portion is formed in an area which excludes a pivoting area in which the arms make their pivotal motions and which is adjacent to the pivoting area. The shutter base plate and the thick-walled portion are integrally formed of a synthetic resin.
