ROTATING CONNECTOR DEVICE

A rotary connector device (1) comprises a first case (10), a second case (20), and a stopper structure (70). The stopper structure (70) includes a movable member (71), a movement conversion portion (72), and a stopper (73). The movable member (71) is rotatable about a rotation axis (A1) with respect to the first case (10) along with the second case (20) and movable in an axial direction (D1) defined along a rotation axis (A1) with respect to the first case (10) and the second case (20). The movement conversion portion (72) converts a relative rotation of the first case (10) and the second case (20) into a movement of the movable member (71) in the axial direction (D1) with respect to the first case (10) and the second case (20). The stopper (73) is provided on at least one of the first case (10) and the second case (20). The stopper (73) is contactable with the movable member (71).
