A rotary connector device includes a fixed body, a rotation body, and a connector. The rotation body is rotatable about a rotation axis with respect to the fixed body. The connector includes a cover, a conductor, and a holding member. The cover includes a first wall and a space therein. The first wall extends from the rotation body in an axial direction substantially parallel to the rotation axis. The holding member is attached to the cover in the space and holds the conductor. The holding member includes, in the first wall, an exposed portion exposed to an outside of the space. The cover and the holding member include a restriction structure to restrict foreign matter from entering the space through the exposed portion. The restriction structure includes a first protrusion that protrudes in a direction substantially orthogonal to the first wall and a first recess in which the first protrusion is fitted.

Rotary connector device and rotation body of rotary connector device

A rotary connector device includes a fixed body and a rotation body. The fixed body includes an internal space. The rotation body is rotatably assembled to the fixed body about a rotational axis with respect to the fixed body. The fixed body includes an inserted portion into which a fixing tool is to be inserted to restrict the fixed body and the rotation body from rotating relative to each other. The inserted portion includes an inner space isolated from the internal space of the fixed body.

Rotary connector device and fixed body of rotary connector device

A rotary connector device includes a fixed body, a rotation body, and an inhibiting structure. The fixed body includes a first fixed body portion and a second fixed body portion disposed facing each other with a space being defined between the first fixed body portion and the second fixed body portion. The first fixed body portion and the second fixed body portion are coupled at a coupling portion. The rotation body rotatably is assembled to the fixed body. The inhibiting structure is configured to inhibit foreign matter from entering the space through the coupling portion. The coupling portion is exposed to an outer surface of the fixed body.
