In a device for driving the brush body (1) of electric toothbrushes, having an electric motor (8) and a gear mechanism arranged between a motor pinion (12) and the brush body (1), to achieve a large oscillation angle with a large torque for the brush body (1), the motor pinion (12) is connected to a gearwheel (10) which has a cylindrical body (9) eccentrically on one end face (10'). The cylindrical body (9) can be moved between two sliding bodies (4, 4') which are plane-parallel with spacing, are designed to be pivotable, and are firmly connected to the drive shaft (2) of the brush body (1). <IMAGE>
