Summary:PROBLEM TO BE SOLVED: To provide a dental syringe capable of finely adjusting a flow rate.SOLUTION: There is provided a dental syringe where a protrusion 17 that protrudes inward to a flow channel is formed on an inner wall of a valve 12 forming the flow channel. A corner part 21 which is a junction part for a lower surface part of the valve and a flat part 20 of the valve is formed in the protrusion 17. A curved part 18 that is protrusively curved toward the protrusion 17 is formed at the bottom edge of a spool 15. A flow rate first control part 23 where the diameter of the curved part is largest and a flow rate second control part 24 where the diameter of the curved part becomes smaller gradually as it goes higher than the flow rate first control part 23 are formed at the curved part 18.SELECTED DRAWING: Figure 7 【課題】 流量を細かく調節することができる歯科用シリンジを提供する。【解決手段】 流路を形成するバルブ１２の内壁に、内側に向けて流路に突出した突出部１７を形成し、突出部１７に、バルブ下面部とバルブ平坦部２０との連接箇所である角部２１を形成する。一方、スプール１５の下端に、突出部１７に向けて突状に湾曲した湾曲部１８を形成し、湾曲部１８に、直径が最大である流量第一制御部２３と、この流量第一制御部２３よりも上方に向かうにつれて直径が徐々に縮径した流量第二制御部２４とを形成する。【選択図】 図７
