PROBLEM TO BE SOLVED: To provide a lens drive device able to reduce variations in the pressing force applied to a movable body by a spring member, by adjusting the pressing force of the movable body by the spring member by a simple configuration even if the spring characteristic of a spring member connecting a movable body and a fixed body varies.SOLUTION: In the lens drive device, a sprig member 5 connecting a movable body 2 and a fixed body 3 comprises: a movable body fixed part 5a fixed to the movable body 2; a fixed body fixed part 5b fixed to the fixed body 3; and an arm part 5c connecting the movable body fixed part 5a and the fixed body fixed part 5b. Also, the spring member presses the movable body 2 toward a reference position of the movable body 2 in the direction of an optical axis. The movable body 2 has a movable side spring fixed part 8b to which the movable body fixed part 5a is fixed. This movable side spring fixed part 8b has a movable side projecting part 8e projecting toward and abutting on the movable body fixed part 5a. |
