The present invention relates to both-sided toothbrush. A fixing ring is accommodated in a hole to keep the length of main bodies same even when one of the multiple toothbrush main bodies rotates 360°. Rectangular parts are formed at the upper part of the hole, and curve supporting parts are formed at the lower part, which eases the movement of the fixing ring inside of the hole even when the handle of the toothbrush rotates. A space part is formed in the front side of the handle to accommodate multiple curve parts formed in the rear side of the handle. The multiple curve parts are formed on the rear side of the handle to be caught by user′s knuckles. H-depth of the space part is lower than s-depth of the other side of the space part. The inner thickness (t) of the handle formed integrally with the space part is thicker than the inner thickness (p) of the handle formed with another space part; therefore, the upper part of the curve part is caught by the space part and a support body having brushes is stretched out at a fixed angle. A head comprises a bending part, and is formed integrally with the support body. The head makes the both brushes touch the teeth effectively, and users can brush the both sides of their teeth at the same time. |
