<P>PROBLEM TO BE SOLVED: To provide a lens module with reduced size. <P>SOLUTION: The lens module includes: a lens body 3; a lens retaining member 5 for retaining the lens body 3 by a side wall along an optical axis z; a fixing member 7 arranged facing the lens retaining member 5 with the lens body 3 in between; and a plurality of link bars 9 arranged in a position holding the lens body 3 from the side wall direction and with a plurality of sets hung across the lens holding member 5 and the fixing member 7. The link bars 9 compose a parallel linking mechanism by the lens retaining member 5 and the fixing member 7. A driving plate 13 is provided arranged in between the fixing member 7 and the lens body 3 in a state with one end side fixed by retaining a prescribed angle of θ=90° to the plurality of link bars 9 arranged at the same height to the optical axis z among the link bars 9 and at the same time having the other end being a free end 13a. In addition, a displacement element 15 is included deformed by application of voltage and arranged in between the fixing member 7 and the lens body 3 in a state of pressing the free end 13a side of the driving plate 13 by this deformation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
