Rotary connector device and fixed body of rotary connector device

A rotary connector device comprising:

• a fixed body comprising an internal space;
• a rotation body rotatably assembled to the fixed body about a rotational axis with respect to the fixed body;
• the fixed body comprising 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;
• and
• the inserted portion comprising an inner space isolated from the internal space of the fixed body, wherein
• the fixed body comprises a first wall substantially perpendicular to the rotational axis, and a second wall disposed at a distance from the first wall in an axial direction substantially parallel to the rotational axis,
• the inserted portion comprises a first opening provided in the first wall,
• the fixed body comprises a third wall extending from an outer edge of the first opening in the axial direction and connected to the second wall, and
• the third wall and the first wall are formed of a single member.

A fixed body of a rotary connector device, comprising:

• a fixed body main body to be assembled to a rotation body rotatable about a rotational axis;
• an extending portion comprising an internal space and connected to the fixed body main body;
• a first wall substantially perpendicular to the rotational axis;
• and
• a second wall disposed at a distance from the first wall in an axial direction substantially parallel to the rotational axis,
• the extending portion comprising an inserted portion into which a fixing tool is to be inserted to restrict the fixed body main body and the rotation body from rotating relative to each other,
• the inserted portion comprising an inner space isolated from the internal space of the extending portion,
• the internal space of the fixed body being provided between the first wall and the second wall,
• the inserted portion comprising a first opening provided in the first wall,
• the inserted portion comprising a second opening provided in the second wall,
• an area of the first opening being substantially identical to an area of the second opening,
• the fixed body main body comprising a first fixed body portion and a second fixed body portion coupled to the first fixed body portion,
• the first fixed body portion comprising a third wall extending from an outer edge of the first opening in the axial direction, and
• the second fixed body portion comprising a fourth wall extending from an outer edge of the second opening in the axial direction, the third wall and the fourth wall being in contact with each other in a direction substantially orthogonal to the rotational axis.
