Abstract
A speed change device arranged such that a driving shaft connecting with a driver and a tool working shaft connected with a driven tool are connected with each other for transmission of torque in the no speed change mode or in the speed change (acceleration or deceleration mode and wherein a manipulating sleeve on the outer periphery of the handpiece case is used for selecting either the no speed change or the speed change mode thereby saving the expense of providing alternative devices for the individual modes of torque transmission.
