PROBLEM TO BE SOLVED: To provide a rotational operation device for a game machine, which can be suppressed in number of failures and reduced in size and cost. SOLUTION: This rotational operation device has a handle operated by a player, a steering shaft 11 to which the handle is attached at its one end, a reaction force means 13 to give reaction force to the steering shaft 11 rotated axially from the neutral position to be returned again to the position, and an armature and a lining mutually set oppositely. An electromagnetic brake 20 to give rotation resistance to the rotated steering shaft 11 based on the contact resistance generated by variation by the distance between the armature and the lining is provided. |
