Rotary connector device

A rotary connector device (1) is provided with a first housing (10), a second housing (20), and a stopper structure (70). The stopper structure (70) includes a movable member (71), a movement conversion part (72), and a stopper (73). The movable member (71) is rotatable together with the second housing (20) about a rotation axis (A1) with respect to the first housing (10), and is movable in an axial direction (D1) defined along the rotation axis (A1) with respect to the first housing (10) and the second housing (20). The movement conversion unit (72) is configured so as to convert relative rotation between the first housing (10) and the second housing (20) into movement of the movable member (71) in the axial direction (D1) with respect to the first housing (10) and the second housing (20). The stopper (73) is provided to at least one of the first housing (10) and the second housing (20), and is capable of coming into contact with the movable member (71). 旋转连接器装置(1)具有第1壳体(10)、第2壳体(20)以及止挡构造(70)。止挡构造(70)包含可动部件
