Claims

[Scope of utility model registration request]

It has an annular governor boss attached to the rotating shaft, a fan-shaped main body part divided into equal circumferences, and a leg part extending in the axial direction of the rotating shaft on the inner peripheral part of the sector-shaped main part, A plurality of governor weights are pivotably mounted to be swingable in the radial direction via the leg rods at equidistant positions on the circumference of the governor boss, and the entire outer periphery of each governor weight and extension of the leg rod. A lining shoe installed in an L-shaped cross section so as to straddle the end face in the side axis direction; a spring that is stretched between the respective governor weights in the circumferential direction and applies a restoring force in the diametrical direction to each governor weight; and a fixed governor case having an annular inner circumferential surface with an L-shaped cross section, which is arranged to be spaced apart from the lining shoe in the radial direction and in the axial direction within the radial swing range of the governor weight. A plurality of governor weights are arranged equally on the circumference of the governor boss, and two surfaces of each governor weight, the entire outer circumference and the axial end surface, are pressed against the governor case via the lining shoe. A centrifugal governor characterized by:
