A shaft position sensor to be used to measure the dimensions of the shape of an object to be measured or to sense the displacement of the object, comprising:
- a housing in which a bearing is provided;
- a measuring shaft having a tip projecting out of said housing and slidably supported by the bearing of said housing;
- a biasing means for biasing said measuring shaft toward said tip;
- a plurality of switching means for operating to open or close in response to the displacement of said measuring shaft and arranged in parallel along the periphery of said measuring shaft;
- a non-pivotable movable body fixed to said measuring shaft, said movable body containing said plurality of switching means in parallel with said measuring shaft;
- and
- a switch operating position adjusting means for adjusting the opening and closing positions of said plurality of switching means.
