PROBLEM TO BE SOLVED: To provide a toothbrush handle, in which a through hole is formed through a toothbrush neck and a bending prevention portion and an elastic groove are formed on opposite sides of an outer circumference of the through hole, so that the bending prevention portion and the elastic groove prevent the neck from being deformed or broken even if the neck is bent beyond a predetermined angle during toothbrushing, and in which a head is flexibly moved, thus allowing the teeth to be easily brushed.SOLUTION: The toothbrush handle according to the present invention comprises: the neck formed between the head and a handle, and curved to protrude toward a front surface of the toothbrush handle; the through hole formed through both a front surface and a rear surface of the neck; the bending prevention portion formed in the neck, located at each of opposite sides on an outer circumference of the through hole to be curved outward along the outer circumference of the through hole, and spaced apart from both sides of the neck by a predetermined interval to define a predetermined space between both the sides of the neck, with an elastic member filled in the space; the elastic member filled in the through hole and coupled to be superposed on a rear surface of the handle; and the elastic groove formed in a rear surface of an upper portion of the elastic member to be opposite to the through hole.SELECTED DRAWING: Figure 1 |
