TOOTHBRUSH HAVING SPRING ENABLING USER TO CORRECT BRUSHING MANNER BY LETTING THE USER RECOGNIZE CONSTRICTION OF SPRING DUE TO RECIPROCATION OF TOOTHBRUSH IN INCORRECT DIRECTION
PURPOSE: A toothbrush having a spring is provided to enable a user to correct a brushing manner by letting the user recognize constriction of the spring due to reciprocation of a toothbrush in an incorrect direction, thereby preventing the user from brushing incorrectly. CONSTITUTION: The toothbrush(100) comprises: a head portion(10) having bristles(11); a handle portion(20); an elastic member(30) connected between the protrusions(12,21) in the form of a spring; protrusions(12,21) installed at ends of the head portion(10) and the handle portion(20), respectively, and spaced apart from each other by a gap corresponding to a constricted distance of the spring; and a cover portion(40) for preventing the elastic member(30) from deviating.
