PROBLEM TO BE SOLVED: To provide a rotation angle detection sensor capable of achieving the reduction in cost. ! SOLUTION: A rotation angle detection sensor 1 includes: a rotor 20 rotationally moving by receiving external force; a sensor element 31 in which characteristic change is generated by strain generated on the basis of the rotational motion; and a cam projection 23 for converting the rotational motion of the rotor 20 into the strain. The rotor 20 rotationally moves, so that the cam projection 23 generates the characteristic change in the sensor element 31 on the basis of the rotational motion. A rotation angle θ of the rotor 20 is identified by detecting the characteristic change. ! COPYRIGHT: (C)2015,JPO&INPIT |
