Abstract

PURPOSE:To effectively prevent a damping operation by suppressing the vibration width depending on application of the repellent action and attractive action of a magnetic force to a damper gear. CONSTITUTION:Permanent magnets 15A, 15B are fixed to a movable holder 14 part and the variation in the intensity of the magnetic field depending on the permanent magnet 15A is detected by a magnetic sensor 12. The magnitude of this detection signal is applied through a DC power supply 16 to an electromagnet 13, and a signal is applied in the direction to provide the attractive action for the electromagnet 13 as the movable holder 14 approach a detecting magnetic sensor 12 and the signal is applied in the direction to provide the repellent action for the electromagnet 13 as the movable holder 14 goes away from the magnetic sensor 12. Thereby, the effect for preventing the damping operation can be improved.
