Abstract
A buckle device in which it can be detected whether or not a tongue plate inserted into a case is locked, and in which reliability of such detection is high. In the buckle device, a magnetic plate is provided at a leg portion which moves together with the tongue plate which is inserted into an interior of the case. Changes in orientation of a magnetic field of a magnet of a sensing section, which orientation varies due to the magnetic plate approaching and moving away from the magnet, are detected at an MRE sensor.
