Abstract
Disclosed is a rotary sensor, in which an engagement portion and a shaft portion are projectively formed on one side and on the other side respectively on the center of rotation of a rotator. The shaft portion is supported by a support portion on the bottom plate. And the engagement portion is movably supported on the support portion as a support point so as to be movable in an arbitrary direction orthogonal to the axial direction of the drive shaft.
Claims6
A rotary sensor, comprising:
- a rotator having an engagement portion with which a drive shaft engages, a housing rotatably supporting said rotator between an upper plate and a bottom plate, and an angle sensing member for detecting the rotation angle of said rotator;
- said rotator having on the center of rotation an engagement portion and a shaft portion projectively formed on one and other sides of said rotator;
- said shaft portion being pivotally supported by a support portion formed on said bottom plate;
- and said rotator being inclinably supported in a direction where its rotator shaft is orthogonal to the axial direction of said drive shaft as said drive shaft is eccentrically shifted with said pivot support being applied as a fulcrum point.
