摘要： A shutter apparatus includes a shutter base plate having an aperture, a blade group configured to open and close the aperture, a blade driving member configured to drive the blade group, a charge lever configured to rotate the blade driving member, a first roller which is attached to a first axis portion extending from the blade driving member and abuts against the charge lever, a cam member configured to rotate the charge lever, and a second roller which is attached to a second axis portion extending from the charge lever and is configured to trace a cam portion formed on the cam member. The cam member has a flange protruding from the cam portion to periphery of the cam member. And the cam member is arranged so that the second roller is overlapped with the flange in an extending direction of the second axis portion.
