A braking device for shutter blades or the like which comprises a pivotable actuating member normally extending into the path of movement of the blade and serving to displace a braking member which is thereby urged against the blade, preferably in a direction at right angles to the direction of movement of the blade, to produce a controlled braking action. The braking member is integral with or is coupled to the actuating member by a torsion spring or the like. Elastic cushions are provided on the actuating and braking members in such positions that the cushion of the actuating member is struck by the moving blade and the cushion of the braking member strikes against the blade in response to resulting displacement of the actuating member.
