Rotary connector
摘要:
Any one of the reversing portions of the flat cables is positioned in the sighting window when the inner case is in the neutral state. A prescribed mark is attached to the reversing portion which is positioned in the sighting window when the inner case is in the neutral state. Thus, it can be determined that the inner case is in the neutral state when the prescribed mark is attached to the reversing portion sighted through the sighting window.
