摘要： A stabilizer (10) includes a base (20) fixed on a motion reduction target (1); a gimbal (40) supported by the base to be rotatable around a first axis (RA); a damper mechanism (30) disposed to damp a relative rotary motion of the gimbal (40) to the base (20); a flywheel (50) disposed to be rotatable around a second axis (RB) orthogonal to the first axis (RA). The damper mechanism (30) is a passive-type damper mechanism. A first value (D1) of a damping coefficient (D) of the damper mechanism (30) when an angular velocity of the gimbal (40) is a first angular velocity is larger than a second value (D2) of the damping coefficient (D) of the damper mechanism (30) when the angular velocity of the gimbal (40) is a second angular velocity smaller than the first angular velocity.
