Summary:PROBLEM TO BE SOLVED: To allow a user to experientially learn a right toothbrushing method preventing an application of an excessive force to a brush while preventing the hurting of the alveolar arch of a user in a simple structure. SOLUTION: When a pressing force of a brush part 2 to teeth and the alveolar arch is increased even a little, vibration transmitted from a vibration generation means 4 to the brush part 2 via a movable part 3 is absorbed to stop the reciprocation of the brush part 2 and, when the pressing force of the brush part 2 is slightly reduced in response thereto, the reciprocation of the brush part 2 is restarted, so that the repetition of the stop and start of the reciprocation of the brush part 2 caused by the slight load change allows the user to experience such an extremely little load change that prevents the opening of the bristles of the brush 2a.
