PROBLEM TO BE SOLVED: To provide a compact anti-rolling device providing a desired anti- rolling effect. SOLUTION: The anti-rolling device 11 includes a base body 12 fixed on hull 10a, gimbal 13 provided on the base body 12, a damper 14, a fly wheel 15 provided on the gimbal 13, and a motor rotating the fly wheel 15. The gimbal 13 is supported rotatably around a first axis X1 by bearings 30, 31 built in side wall parts 21, 22 of the base body 12. The fly wheel 15 rotates around a second axis X2. A rotor member 40 of the motor 16 is attached on the flywheel 15. A stator member 41 is provided on the gimbal 13. The rotor member 40 and the stator member 41 are arranged within a rotation locus during oscillation of the gimbal 13. A cover part 23 covering an outer surface of the gimbal 13 is provided on the base body 12. |
