Patent attributes
To provide a tilt angle sensor that is capable of detecting acceleration, a tilt angle, and the like of a device to which the tilt sensor angle is mounted, and also capable of reducing the size and the cost with a simple structure. The tilt angle sensor comprises: a spring member having a fixed end a free end that has a flexibility to be bent at least in one direction; a magnetic field generating device for generating a magnetic field, which is mounted at the free end of the spring member; a magnetic field detecting device provided by facing the magnetic field generating device for detecting a direction of the magnetic field generated by the magnetic field generating device; and a damping device for giving a damping force to a bending action of the spring member.
