To provide a shutter device dispensing with a conversion of a driving direction when disposing a driving source with making its output shaft parallel to a photographing optical axis.

A shutter bottom board 1 is formed with a first shaft 1b that is parallel to an optical axis 49 of a photographing luminous flux, and a blade lever 15 is rotationally turned about the first shaft 1b to drive a first blade 41 and a second blade 42. A drive lever 11 is turned about the first shaft 1b to drive a blade lever 15. A second cam gear 22 is rotated about a second shaft 1d that is so formed on the shutter bottom board 1 as to become parallel to the first shaft 1b, to charge a blade-driving spring 14. A first cam gear 21 is rotated about a third shaft 1c that is so formed on the shutter bottom board 1 as to become parallel to the first shaft 1b, to change over between a state of holding the blade lever 15 for making the first blade 41 and the second blade 42 close an aperture and a state of releasing the holding of the blade lever 15.
