DAMPING MEMBER AND ROTARY CONNECTOR DEVICE

A damping member reduces noise between a rotary connector device and a vehicle body side, which are connected. An engaging portion is inserted through the damping member, and is provided in a rotary connector device. The engaging portion engages with an engaged portion provided in a vehicle body side, and includes an engaging shaft extending in an insertion direction and an engaging claw protruding from the tip side of the engaging shaft. The damping member is formed of butyl rubber, and includes a first slit through which the engaging shaft is inserted and a second slit extending from the first slit toward the protruding direction side of the engaging claw. The first slit and the second slit communicate with each other, the engaging portion being inserted there through.
