PROBLEM TO BE SOLVED: To provide a camera shake compensation device by which a compensation optical element is exactly supported by simple structure in an image stabilization device incorporated in a lens part of an imaging system. SOLUTION: Arms (6a, 6b) are inserted into arm guides (2a, 2b) to be floatable on an XY plane. An arm (7) is slidably inserted in a hole (11) penetrating the side of a rotary bearing (9) and the rotary bearing (9) is pivotally supported to be freely to Y-θby an axis (10) by a hole which is not illustrated, punched on a main body (1) in parallel with a light axis and a hole punched on a rotary bearing pressure foot (12) to be installed by poles (4a, 4b) provided on the main body. A mirror frame (5) freely moves in the Y direction without accompanying rotation and freely moves in the X direction while accompanying the rotation. A mirror chamber (5) moves its center to be freely to X-Y by permanent magnets (14a, 14b, 14c, 14d) consisting at least of two coils to one of a coil (13a) and a coil (13b) installed in coil holders (8a, 8b).
