Abstract
A transmission device for use in a dental handpiece has a modular unit comprising an input shaft coaxial to and driven by the motor shaft, and an oblique shaft extending obliquely with respect to the input shaft and also to the tool driving shaft. Each end of the oblique shaft carries a bevel pinion, one bevel pinion meshing with a bevel wheel fixed to the input shaft and the other bevel pinion meshes with another bevel wheel fixed to the tool driving shaft. The input and oblique shafts are mounted in suitable bores formed in a socket, the oblique bore remaining without the peripheral limits of the socket. The socket is adapted to be forcibly fitted into the handle of the handpiece.
