Abstract
A lens drive mechanism includes a drive source; a lead screw that is connected to the drive source and rotated by operation of the drive source; a nut member that screws on the lead screw and moves as the lead screw rotates; a lens hold portion that is so disposed as to move as the nut member moves and hold a lens; a guide member that guides the lens hold portion to move in the same direction as that of movement of the nut member; and a leaf spring member that if the nut member is situated near one end of a thread portion of the lead screw, pressurizes the nut member toward the other end of the thread portion of the lead screw.
