Claims

[Claims for Utility Model Registration] (1) A first shaft rotatably supported by a housing;
an annular permanent magnet attached to the first shaft via a sleeve; a second shaft rotatably supported by the casing and disposed opposite to the first shaft; , a continuous body connecting the first shaft and the second shaft, a magnetic core fixed to the second shaft, and a magnetic core fixed to the housing and in the vicinity of the outer peripheral surface of the magnetic core. A relative displacement detection device comprising a magnetic sensor held between magnetic members disposed in the first shaft body and a magnetic sensor sandwiched between the first shaft body and the magnetic core. A relative displacement detection device characterized in that the magnetic sensor detects the direction of relative position change and the amount of change in displacement about the rotation axis of the second shaft body. (2) A cylindrical sub-first body which is integrally connected to the first shaft body and into which the connecting body is inserted.
The relative displacement detection device according to claim 1, wherein the sleeve is attached to a shaft body.
