A position detecting apparatus for generating a position detection signal when the sensor comes into contact with a workpiece is equipped with a swivel mechanism which allows the sensor to move in any direction within a constant range at the time of contact. This swivel mechanism comprises a metal cylinder for supporting the sensor, a mechanism for moving in the vertical direction guided by a center shaft supported by a swivel bearing, and a mechanism for moving the metal cylinder and center shaft in the horizontal direction. When the sensor contacts the workpiece, a display, for example, is lit up by a position detection circuit.
