Contains things related to connectors. In recent years, a dental treatment instrument has been developed that is equipped with a light source T and a conductor assembly that extends in the direction of the y part in the direction of the ya part to illuminate the entire affected area. As a result, it has become widely used, but if a malfunction occurs in the hand-held member of a dental treatment instrument equipped with this illumination mechanism, a conventional dental treatment instrument without an illumination mechanism can be used in place of the hand-held member. Even if an attempt was made to use a hand-held member, the connection mechanism between the hand-held member and the joint member of the dental treatment instrument equipped with the illumination mechanism was different, so there was an inconvenience that the conventional dental treatment instrument could not be fully utilized.
