The governor is pivoted from an operating position in which the rotatable portion rotates in response to car movement, to an operated position, in response to the locking of the rotatable portion to the fixed portion by predetermined car speed in the down travel direction. Movement of the governor to the operated position actuates a car safety via a suitable link.
