Abstract
A shutter for a camera includes a lever pivotable for operating a shutter, a shutter base plate formed from a synthetic resin, a shaft for pivotally supporting the lever, the shaft and the shutter base plate being formed from a synthetic resin as one unit, and a thick portion formed on the surface of the shutter base plate on which the shaft is formed. The thick portion is formed in a contiguous area of the shutter base plate surrounding the shaft so that the shaft surrounding area is made thicker than the area surrounding an aperture of the shutter base plate.
