換装置。[Scope of Claim for Utility Model Registration] (1) A printed wiring board equipped with a multiple-turn detection coil is placed across the air gap of an AC-excited magnetic core, and the interlinkage magnetic flux of the detection coil is transferred between the magnetic core and the printed wiring board. In a displacement conversion device that changes the shape according to the relative displacement between the magnetic core and the printed wiring board, the shape of each turn of the detection coil is made symmetrical with respect to a center line parallel to the direction of relative displacement between the magnetic core and the printed wiring board, and each turn is changed according to the relative displacement between the magnetic core and the printed wiring board. Displacement transducers arranged sequentially shifted along the center line. (2) The displacement converter according to claim 1, wherein the printed wiring board is cylindrical. (3) The displacement converting device according to claim 1, wherein the printed wiring board has an annular disk shape.
