DISPLACEMENT DETECTING DEVICE AND CONTINUOUSLY VARIABLE TRANSMISSION DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/056854

Kind Code:

A1

Abstract:

[Problem] To provide a displacement detecting device and a continuously variable transmission device that directly detect the position of a movable sheave. [Solution] The displacement detecting device comprises: a magnet 62 that forms a magnetic field; a movable sheave 21, the object to be measured, that rotates and is displaced in a direction perpendicular to the rotation direction, said movable sheave having a concave portion 210 (or a convex portion) in the circumferential surface; and a sensor 60 that is disposed between the magnet 62 and the circumferential surface of the movable sheave 21 and that detects a change in the magnetic flux density accompanying a displacement of the movable sheave 21 in the magnetic field formed by the magnet 62 and induced to the concave portion 210 (or the convex portion).
