Claims

[Scope of utility model registration request]

(1) A rotating shaft that is rotatably supported inside the head of the handpiece, an exchange shaft that is detachably attached to the inside of this rotating shaft, and a handle of a cutting bar that is attached to the inside of this exchange shaft. In the chuck for a handpiece, the outer circumferential wall surface of the intermediate tube is recessed in the circumferential direction, and the friction chuck is replaced by attaching and detaching the exchange shaft to and from the rotating shaft. The intermediate tube is provided with a flexible exchange shaft having a plurality of slots parallel to the center line, and an elastic body that covers the outer peripheral wall surface of the intermediate tube. A chuck for a handpiece, characterized in that a handle of the cutting bar or the like is fixed to the friction chuck by the elasticity of the intermediate tube body and the elasticity of the elastic body.

(2) The intermediate tube is embedded in an elastic member, the elastic member on the inner peripheral wall of the intermediate tube acts as the friction chuck, and the elastic member on the outer peripheral wall of the intermediate tube acts as the friction chuck. Utility model registration claim 1 (claim 11) The chuck for a handpiece is characterized in that it acts as an elastic body.
