PROBLEM TO BE SOLVED: To provide a camera shake correction device and a zoom lens unit which can be made compact, and suppress hysteresis of a movement locus and a rotation of a moving lens when the lens moves.SOLUTION: A camera shake correction device includes: a base 41 fixed to a main case 1; and a slider 61 which supports lenses 18 and 19, and which can freely move in a direction orthogonal to an optical axis of the lenses 18 and 19 for the base 41. Three balls 81 and two coil springs 82 are arranged between the base 41 and the slider 61. The coil springs 82 are locked by the slider 61 and the base 41 which are on both sides of the balls 81, and attracts and holds them. A center of gravity of a line segment connecting these coil springs 82 matches the optical axis of the lenses 18 and 19 supported by the slider 61 in a neutral position. |
