Abstract
To provide a displacement detection device and a continuously variable transmission that directly detect the position of the movable sheave. A displacement detection device includes a magnet that forms a magnetic field, a movable sheave that is rotated in a rotational direction and displaced in a direction perpendicular to the rotational direction and that is a measuring object having a concave portion (or a protrusion) on the circumferential surface, and a sensor disposed between the magnet and the circumferential surface of the movable sheave and detecting a change in magnetic flux density due to the displacement of the movable sheave in the magnetic field formed by the magnet and induced to the concave portion (or the protrusion).
