<p>PROBLEM TO BE SOLVED: To provide an automatic moving toothbrush which can easily exchange a bunch of bristles to be used to move toward a longitudinal direction by being connected to a drive side. SOLUTION: This automatic moving toothbrush has the bunch of bristles 11 protruded from a base 11a, and the toothbrush body 2 a part or the whole of which becomes a grip 1, and a drive structure 8 which is set within the body 2, connected to the bunch of bristles 11 detachably and moves the bunch of bristles 11 automatically toward a longitudinal direction at the end of the body 2. The object of this invention is achieved by connecting the bunch of bristles 11 to the drive structure 8 detachably in a moving direction by magnetic coupling by magnetic attraction of a magnetic coupler 25 set in both the base 11a of the bunch of bristles 11 and the moving action 23 of the drive structure 8.</p> |
