Claims

[Scope of utility model registration request]

A front cylinder part with a slightly larger inner diameter and a rear cylinder part with a slightly smaller inner diameter are formed separately through a stepped part in a cylindrical motor casing constituting a part of the gripping part, and in the front cylinder part, one A partition plate having a pair of ventilation holes around the periphery, an air motor having an air supply recess and an exhaust recess facing the pair of ventilation holes, respectively, and a holding plate are successively tightly fitted into the motor casing. A tightening member screwed onto the front end portion is used to press and fix the stepped portion in the force direction, and the output shaft of the air motor is connected to the rotating shaft of the cutting bar. A joint that tightly fits a rotation control member having an air supply passage and an exhaust passage therein which communicate with the ventilation hole, and has an air supply hole and an exhaust hole on its rear surface that communicate with the air supply passage and the exhaust passage, respectively. A dental handpiece equipped with an air motor in which cylindrical parts are joined together and pressed in the direction of the partition plate by a cap nut screwed onto the rear part of the motor casing.
