Abstract
A dental tool having a head with an output spindle to which are coupled dental treating devices such as a dental massaging brush. The output spindle is driven with a reciprocatory rotary motion imparted to it from a rotationally driven drive shaft coupled to the output spindle by a drive coupling device which converts the rotational motion of the drive shaft to reciprocatory rotary output of the output spindle. An O-ring effects a seal about the output spindle where it extends outwardly of the head. The drive coupling device has an eccentric stud fixed eccentrically to the drive shaft extending therefrom from one side to the other of a projection of the longitudinal axis of the drive shaft and making an angle with the projection of the axis. The eccentric stud is received in an axial slit in the output spindle for effecting the motion conversion.
