    摘要： A liquid tank capable of preventing a gas passage from being clogged and a dental device including this liquid tank are provided. A liquid tank having an accommodation space in which a liquid L to be supplied to outside is accommodated includes a tank body having a mouth part with an opening, a cap mounted on the mouth part to close the opening, a liquid passage through which the liquid L in the liquid tank flows toward outside, a gas passage having a gap between the mouth part and the cap and a path communicatively connecting to the gap and the accommodation space, a liquid flow valve provided on the liquid passage to allow or inhibit a flow of the liquid L to outside, and an aeration valve provided on the gas passage to compensate for a negative pressure occurring in the accommodation space.

    摘要： An object is to provide a control device of a dental handpiece that is able to prevent giving a shock to the operator having the dental handpiece and the patient of treatment subject and also that is able to reduce the load onto the motor and to suppress heat generation thereof. The rotational direction of a motor 20 of a dental handpiece is switched at every certain time. At this time, before the rotational direction of the motor 20 is switched through switching of a relay 17, voltage to be applied to the motor 20 is reduced. It is thereby prevented that a large current flows into the motor 20 when the relay 17 is switched, and also that a large rotation torque is applied to a cutting tool rotationally driven by the motor 20.

    摘要： The present dental handpiece has a burr sleeve, a head section, an air supply passage for introducing compressed air into the head section for driving the burr sleeve, and an air discharge passage for discharging the compressed air. The air supply passage includes a through hole axially extending through the rear terminal part of the handpiece, and a tubular pressure regulating member and an air supply tube connected in series between the through hole and the head section. The pressure regulating member has an aperture for allowing communication with the air discharge passage, and an annular valve body arranged axially slidably for opening/closing the aperture. When the pressure of compressed air passing through the air supply passage exceeds a predetermined level, the valve body is slid to open the aperture to discharge the compressed air for regulating the pressure of the compressed air to be supplied to the burr sleeve.
