Zusammenfassung: | A governor is provided with a pulley comprising a casing, a pulley rotatably supported by the casing and a long member wound around the pulley. The pulley is rotated when the long member is pulled. A spring member is provided for urging the pulley in the direction in which the long member is wound up. A braking device is provided for braking the pulley when the long member is pulled. A long member winding up portion is formed in the pulley so that winding up diameters thereof change as the long member is being pulled out which, in turn, changes the operation of the braking device. |
