VIBRATING TOOTHBRUSH

摘要

The present invention comprises a toothbrush head part including an insertion groove formed inside, and a catching protrusion protruding from a side surface of the insertion groove; and a connection member including a connection member body, a first insertion portion protruding from one side in a length direction of the connection member body and coupled to the insertion groove, and a coupling protrusion protruding from the external circumference surface of the first insertion portion. Accordingly, the possibility of fatigue fracture due to external force applied in a radial direction can be significantly reduced.
