的効果が大である。 As described above, according to the present invention, a cylindrical electrode terminal and a cylindrical electrode terminal are provided at the bottom of a holder into which a charger for charging a storage battery built into a dental treatment instrument driven by a cordless motor and a treatment instrument are inserted and held. A rod-shaped electrode terminal located at the center of the cylindrical electrode terminal is elastically attached via separate springs,
Since the output lead wire of the charging circuit is connected to both electrode terminals, even if the treatment instrument is inserted into the holder at an angle, the cylindrical electrode terminal and the rod-shaped electrode terminal will not resist the spring due to the weight of the treatment instrument. At the same time, the cylindrical electrode terminal tilts to make stable contact with both electrode terminals of the storage battery attached to the end face of the treatment instrument, ensuring reliable charging. Therefore, the charger can be placed on an inclined surface. Moreover, it has a simple structure and can be provided at low cost, which has great practical effects.
