POSITION DETECTING SENSOR, A CLUTCH ACTUATOR INCLUDING THE SAME, AND A CLUTCH DEVICE INCLUDING THE SAME, CAPABLE OF DETECTING A POSITION OF A NON POSITION DETECTING MEMBER BY DETECTING THE CHANGE OF A MAGNETIC FIELD OF A MAGNETIC FIELD GENERATING MEMBER

摘要

PURPOSE: A position detecting sensor, a clutch actuator including the same, and a clutch device including the same are provided to reduce the costs and to precisely detect the position with a magnetic field generating member when a lineal movement of a non-position detecting member is big.;CONSTITUTION: A position detecting sensor(1) comprises a magnetic field generation member(3) and a magnetic field detecting unit(4). The magnetic field generation member includes a soft magnetic body(3a) installed in a lineal movement direction of a non-position detecting member(2) and a pair of magnets(3b,3c). The magnetic field detecting unit converts change of a magnetic field of the magnetic field generating member into an electric signal.;COPYRIGHT KIPO 2013
