PROBLEM TO BE SOLVED: To provide an oscillating drive device permitting oscillation in multiple directions by one motor and realizing at the same time the simplification in the configuration in device itself and price reduction at the same time for the polarizing plate. SOLUTION: This device is equipped with a support plate supporting almost the central portion of the rear surface of a polarizing plate for a polarizing door of a kitchen or the like, three oscillating rods with rollers attached to the tip portions contacting to the rear surface of the polarizing plate and the arm length being different each other, a base portion of the arm of the oscillating rods being coupled and a rotation drive section to which a support plate is coupled through a joint in a freely oscillating manner, a motor for rotating the rotation drive section, and a spring exerting the polarizing plate so that the rear surface of the polarizing plate always comes into contact with the roller, and by rotating a plural of oscillating rods in the circumferential direction by the rotation of a rotation drive section, the contact position to the rear surface of the polarizing plate of each roller varies and the polarizing plate is oscillated in multiple directions as the characteristics of this device. |
