置。[Claims for Utility Model Registration] (1) A key 1 that is moved over a certain distance by a pressing force applied to the key top 1a, a key receiving portion 2 that guides this key 1, and a key receiving portion 2 that guides this key 1 in a direction opposite to the pressing direction described above. In a key device equipped with a spring 5 that biases in a direction, a magnet 3 is provided on one of the key 1 and the key receiving portion 2, and a magnetic flux generating portion 4 that generates magnetic flux acting on the magnet 3 is provided on the other. A key device characterized in that the magnet 3 and the magnetic flux generating section 4 change the restraining force according to the movement of the key 1. (2) The magnet 3 is a bar magnet 3 installed below the key top 1a and magnetized with different polarities on the upper and lower ends.
The key device according to claim 1, wherein the magnetic flux generating section 4 has a coil 4a whose upper and lower ends are magnetized with different polarities.
