| titleOfInvention | Lens drive device |
| abstract | In a lens drive device 1, a protrusion P is provided in a housing part 43 of a lens frame body 40, and a point at which the protrusion P comes in contact with a second surface f2 of a fixed end 51b serves as a fulcrum of a leaf spring member 51. The protrusion P can be provided at a designed position, and product-to-product positional variations cannot substantially occur. Therefore, also regarding a fulcrum P2 of the leaf spring member 51, which is determined by the position of the protrusion P, product-to product variations do not occur. Accordingly, variations in the distance between the fulcrum P2 of the leaf spring member 51 and a point of application P1 are suppressed, and variations in the biasing force of the leaf spring member 51, which is determined according to the distance between the fulcrum P2 and the point of application P1 are also suppressed. Consequently, frictional force of frictional engagement between a frictional engagement member 50 and an actuator 54 is made uniform, thereby achieving a uniform drive characteristic of the lens drive device 1. |
