An amusement device (1) with a central shaft (2) which includes a base structure (2a); and a plurality of arms (3a, 3b, 3c, 3d), coupled to the central shaft (2), each of the arms (3a-3d) being rotatable around a relevant arm axis (A2), provided with one or more vehicles (6) having seats for users of the amusement device (1).

Amusement device (1) comprising: a central shaft (2) comprising a base structure (2a); a plurality of arms (3a, 3b, 3c, 3d), coupled to said central shaft (2), each of said arms (3a-3d) being rotatable around a relevant arm axis (A2), provided with one or more vehicles (6) having seats for users of said amusement device (1); a gear system (7) for rotating said plurality of arms (3a-3d). The gear system (7) comprises a gear motor (M) coupled to a first gear (71), to rotate said first gear (71) and a plurality of second gears (72a, 72b, 72c, 72d), one for each arm (3a, 3b, 3c, 3d) of said plurality of arm, coupled to said first gear (71) so that rotation of the first gear (71) drives in rotation said second gears (72a-72d), the rotation of said second gears (72a-72d) causing rotation of each arm (3a-3d) around the relevant arm axis. The gear system (7) is configured so that the angular speed of said arms (3a-3d) is substantially identical for all the arms. The first gear (71) is directly meshing with said second gears (72a-72d), or it is coupled to said second gears (72a-72d) via one or more secondary gears.
