Claims

[Scope of utility model registration request]

(1) A holder that rotates together with the rotating body to be measured, a governor weight supported on the holder via an elastic member having elasticity in a plane perpendicular to the rotation axis of the holder, and a centrifugal force applied to the governor weight. a switch that operates when the governor weight moves against the elasticity of the elastic member, the governor switch device comprising: a switch that operates when the governor weight moves against the elasticity of the elastic member; What is claimed is: 1. A governor switch device comprising an additional elastic member that provides an elastic force that resists.

(2) The governor switch device according to claim 1, wherein a static distance between the additional elastic member and the governor weight is adjustable.
