1. A rotary connector device comprising:
a first case;
a second case, the first case and the second case being rotatably provided relative to each other about a rotation axis, the first case and the second case defining a cable housing space provided to surround the rotation axis;
a stopper structure to restrict a relative rotation of the first case and the second case within a predetermined rotation angle; and
the stopper structure comprising:
a movable member rotatable about the rotation axis along with the second case with respect to the first case, the movable member being movable in an axial direction defined along the rotation axis with respect to the first case and the second case;
a movement conversion portion to convert the relative rotation of the first case and the second case into a movement of the movable member in the axial direction with respect to the first case and the second case; and
a stopper provided on at least one of the first case and the second case, the stopper being contactable with the movable member.
