发明名称 LENS-DRIVING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a lens-driving device having simple configuration and driving lenses without rattling. SOLUTION: A magnet 21 is arranged on a lens holder 10 side, and a shaft 50 which supports the lens holder 10 is formed of a magnetic material. A pore 12, into which the shaft 50 is inserted, is nearly triangular. The shaft 50 is pushed against the two inner surfaces of the pore 12 by magnetic force in an arrow direction generated between the shaft 50 and the magnet 21, and the relative displacement, in the vertical direction to the shaft 50, between the pore 12 and the shaft 50 is regulated. Accordingly, rattling in driving the lens holder 10 is effectively restrained. COPYRIGHT: (C)2008,JPO&INPIT
