WIPO Patent Application WO/2011/027686

A1

A lens drive device configured in such a manner that the guide function of shafts is sufficient and the movement load of a lens module is reduced in comparison with conventional products. Shafts include a primary shaft (51) which is one of the shafts and a secondary shaft (52) which is other than the main shaft. Holes for the shafts comprise a primary shaft hole (15) in which the main shaft (51) is inserted and a secondary shaft hole (16) in which the secondary shaft (52) is inserted. The area of a portion of the inner peripheral surface (16a) of the secondary shaft holes (16), said portion being in sliding contact with the outer peripheral surface (52a) of the secondary shaft (52), is less than the area of a portion of the inner peripheral surface (15a) of the primary shaft hole (15), said portion being in sliding contact with the outer peripheral surface (51a) of the primary shaft (51).
