In the focal plane shutter (1), one end of the biasing member 31 and engages with the opening lever (30) that drives the front curtain 130, the force applied in the counterclockwise direction, the open lever 30 is an electromagnet (40 ) there is a rotation in the counterclockwise direction is regulated by the. In addition, the other end of the biasing member 31 and a force is applied in a clockwise direction engages with the ratchet member 32, there is a clockwise rotation is regulated by the ratchet member 32. Film speed adjustment mechanism (2a) has a length of any other of the plurality of claw portions (33a1, 33a2) with the ratchet teeth (32a) to adjust the stop position of the ratchet member 32 by being fit to walk, the biasing member 31 and the ratchet by changing the engagement state of the member 32, it is possible to adjust the urging force of the biasing member (31) controls the film speed of the focal plane shutter (1).
