A braking device for focal plane shutter in a photographic camera, in which the braking device has a braking function in its reciprocating motion. The braking device is moved forward by a shutter opening member near the end of aperture opening by the shutter opening member, and is moved backward by the shutter closing member near the end of aperture closing. During its reciprocating movement, braking force is applied to the shutter opening and closing members, and, in association with forward movement of the shutter opening and closing members, synchro-switch contacts are closed, while they are opened in association with the backward movement thereof. Further, in association with return of the aperture opening member to its original position at the shutter charging, the braking device is made returnable to its initial position.
