Abstract
PURPOSE: To control a rotation at a predetermined speed by a construction wherein a shoe capable of expanding outwards under a centrifugal force is provided and a torsion spring is placed on the outside of the shoe so that the shoe provides a braking action by expanding against the torsion spring when the rotational speed reaches or exceeds a preset value.
CONSTITUTION: A shaft 1 is fitted with the shoe 3 by a pin 4 through a fitting shaft 2. The shoe 3 consists of a pair of shoe members having a circular outside periphery. The spring 5 is provided on the outside of the shoe 3, with both ends of the spring 5 fixed to the shoe 3. When the rotational speed of the shaft 1 reaches or exceeds the preset value, the shoe 3 expands outwardly against the spring 3 to press against the inside surface of a casing 7, thereby creating a braking action.
