PROBLEM TO BE SOLVED: To provide an objective lens driving-gear capable of correcting a tilt of the objective lens to an optical disk signal recording surface with high performance and at high speed. SOLUTION: A pair of supporting members for supporting a lens holder 2 consists of a first part 128 connected to the lens holder and a second part 126 connected to a fixing part. When a moment is added to the lens holder so that the lens holder rotates in the direction of tangential tilt, rotation rigidity of the first part is smaller than that of the second part. The first part and the second part are formed of elastic members and a wire made of a metal material is housed inside the second part. COPYRIGHT: (C)2004,JPO
