摘要

A focal plane shutter for use in a photographic camera in which a shutter base plate is made of a synthetic resin material and a metallic supporting plate is mounted on a front surface of the shutter base plate. Shafts pivoting levers for driving a leading blade group and trailing blade group are fixed to a front surface of the metallic supporting plate, whereas shafts pivoting arms for driving the leading blade group and the trailing blade group are fixed to a rear surface of the supporting plate. The shafts pivoting the driving arms and supporting arms protrude from a rear surface of the shutter base plate.
