<P>PROBLEM TO BE SOLVED: To provide a sensor capable of easily detecting an axial direction position of a measuring object rotating around the axis without increasing cost. <P>SOLUTION: In a sensor 1 for detecting an axial direction position of a measuring object 2 which displaces in the axial direction while rotating around the rotation axis, a first element 6 and a detector 5 having a magnetic member 7 are provided. A second element 8 for performing a predetermined linear displacement to the first element 6 while cooperating therewith at the time of the linear relative displacement is formed by the magnetic member 7 and is constituted so that the second element 8 is conveyed contactlessly due to the linear relative displacement by the measuring object 2 in order to produce a position signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
