发明名称 SENSOR DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a compact sensor device obtaining stable output characteristics. SOLUTION: The sensor device includes a detection coil 21, a conductive cylindrical body 32 which is disposed around the detection coil 21 and displaced relatively to the detection coil 21 in a winding shaft direction of the detection coil 21, a control board 4 which outputs a position signal indicating a relative position of the conductive cylindrical body 32 to the detection coil 21 based on an inductance of the detection coil 21 which changes depending on a displacement of the conductive cylindrical body 32, and a movable body 30 which supports the conductive cylindrical body 32 at an intermediate portion of the conductive cylindrical body 32 in the displacement direction and is displaced movably together with the conductive cylindrical body 32 within a predetermined range.
