ABSTRACT:
A sealing device has a sealing assembly disposed between a pair of a fixed frame and a first moving frame that relatively circularly move and rectilinearly move. The sealing assembly is fixed by bonding to the fixed frame. Two inclined fins of the sealing assembly are in slidable contact with the outer peripheral surface of the first moving frame. The fins provide a reliable light shielding, waterproofing, drip-proofing, or dust-proofing effect between the fixed frame and the first moving frame. The gap between the first moving frame and a second moving frame and the gap between the second moving frame and a frame are also sealed by the sealing assembly in the same manner. The sealing device permits reliable light shielding, waterproofing, drip-proofing, or dust-proofing, and also enables a lens frame to be made smaller at the same time.
