う構成された車両用キー装置。 In a vehicle key device that drives a controlled object by magnetically coupling communication between a key and a key cylinder, there is a key in which the key grip has a built-in LC having a natural resonance point as key information, and a key on the key insertion hole side. A magnetic core that is fixed to the outer periphery of the rotor and forms a magnetic circuit with the key when the key is inserted; a key cylinder body that houses the rotor and is provided with a cover that surrounds the magnetic core; and a magnetic field generating coil in which the bobbin is provided with a cylindrical part for drawing out a winding, the cover is provided with a hole that communicates with the outside of the key cylinder body, and the cylindrical part of the bobbin is passed through the hole. The vehicle key device is configured such that the winding wire is pulled out of the key cylinder body.
