効果を奏するガバナー装置が提供できる。 Since the present invention is configured as described above, when the controlled member moves in one direction, the speed of movement is controlled by the sliding contact between the sliding member and the annular friction member, and when the controlled member moves in the opposite direction, only the rotating member is idly rotated. uncontrolled,
In addition, since the sliding contact member is rotatably incorporated between the disc of the second rotating member and the inverted L-shaped retaining part by means of the support provided on the disc, the configuration is simple and the sliding contact member is simple. It is possible to provide a governor device that has excellent practical effects such as easy assembly of contact members.
