Abstract
A non-contact displacement detecting device including a permanent magnet fixed with a rotational member, a sensor portion fixed with a non-rotational member, and the sensor portion detects a displacement of a detected object connected with the shaft. The non-contact displacement detecting device includes a housing for supporting the rotational member rotatably and restricting one movement of the rotational member in an axial direction, and a holder for contacting with the rotational member at a plurality of contact points and restricting another movement of the rotational member in the axial direction. Thereby, the movement of the rotational member in the axial direction is restricted by the holder and the housing.
