Rotation load instrument

Abstract

To provide a rotation load instrument that is excellent in reliability of a motion of a rotation shaft being restored to a neutral position.SOLUTION: A cam groove 29 has a cross-sectional shape in which a wedge angle θ formed with a tangential direction at a contact point between an internal surface of the cam groove 29 in a condition, where a steel ball 17 is pushed against the internal surface of the cam groove 29 and an internal surface of an axial groove 28 with a constraint force of an elastic member 19, and the steel ball 17, and an extending direction of the axial groove 28 is equal to or larger than 50° and equal to or smaller than 90°.SELECTED DRAWING: Figure 9
