Abstract
A rotary connector device includes a stator, a rotator, an electrical cable, an electrical connector, and a connector coupling portion. The stator includes a first stator and a second stator. The connector coupling portion is configured to couple the electrical connector to the first stator. The connector coupling portion is configured to support the electrical connector in a cantilever manner with respect to the first stator such that a second surface becomes a free end in a state where the electrical connector is positioned in a first position and where the second stator is detached from the first stator.
