摘要： In an electric toothbrush of the present invention, a head case is detachable from a main case, so that brushes on the head case can be easily washed and kept clean. The orientation of the brushes with respect to the main case can be changed, so that every tooth can be brushed well. A driving force of a motor is transmitted by first and second shafts and gears, so that the force can be positively transmitted to the brush even through the transmitting route is bent. Vibration of the electric toothbrush is less than conventional toothbrushes which alternately rotate brushes because the brushes are rotated by the first and second shafts. Holes of lead-pieces for connecting terminals have inwardly extending claws, and the terminals can be connected only by insertion into the holes, so that assembling steps can be reduced. If the tips of the claws are sharpened, the terminals are held tightly.
