The present invention provides a rotary connector device that enables relative rotation between the rotator and the stator to be easily and reliably fixed at a neutral position even when a steering device is disengaged. A rotary connector device (1) according to the present invention is provided with: a self-rotation pin (50) that is self-rotatable with respect to a sleeve (30) and that is provided with a pin-side notch (521) that restricts the self-rotation by coming into contact with an inner circumferential surface of a stator-side inner-circumferential cylindrical portion (23); a stationary-side gear (231) and a self-rotation-side gear (511) that transmit the relative rotation and the self-rotation in an interlocked manner; and a stationary-side switching mechanism (40) and a pin protrusion (52) that switch, in a neutral position, the self-rotation pin (50) from a released state to a restricted state.
