<P>PROBLEM TO BE SOLVED: To provide a toothbrush with a spring that reduces pressurizing force of a toothbrush, since the conventional brush tends to directly receive hand force when performing brushing with the toothbrush, and often damages the surface of the teeth and the gums. Ž<P>SOLUTION: The toothbrush with a spring is provided with a linear spring at the upper part of a handle, an attachable/detachable part at the top of the spring, a recessed receiving part at the upper end of the attachable/detachable part, and a plug-in piece at the lower end of a head part having a brush part. Thus, the plug-in piece is made freely insertable into the receiving part. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
