The present invention relates to a toothbrush comprising: a neck part formed between a head part and a handle part and bent to protrude toward the front of the toothbrush; a penetration hole penetrating a front surface and a rear surface of the neck part; an anti-bending part formed inside the neck part and outwardly rounded along an outer circumferential surface of the penetration hole at one side and the other side of the outer circumferential surface of the penetration hole; and an elastic member filling the penetration hole and coupled with a rear surface of the handle part. According to the present invention, the penetration hole is formed in the neck part of the toothbrush and the anti-bending part is formed at one side and the other side of the outer circumferential surface of the penetration hole, thereby preventing the neck part from being deformed or broken by the anti-bending part even when the neck part is bent at a predetermined angel or more at the time of tooth brushing, and allowing the head part to smoothly move to easily clean teeth. |
