ABSTRACT:
A structure for connecting a rotating shaft to a rotary sensor, includes a first stator having two magnet-facing sides disposed on an arc and spaced apart, a second stator having one magnet-facing side and disposed between the two magnet-facing sides, a hall element disposed between the first and second stators, a moving magnet having different polarities and disposed along the outside arc of the three magnet-facing sides, and a rotor having the moving magnet. The rotating shaft is loosely fitted in a fitting hole116bof the rotor. The rotating shaft is supported in the fitting hole by a pin, and a clearance-maintaining member maintains the distances between the moving magnet and the first and second stators constant. The rotary sensor can detect angles accurately even if misalignment occurs between the center of the rotor and the center of the rotating shaft.
