Claims

[Claims for Utility Model Registration] (1) The device includes an eccentric cam rotated by a motor, a rolling shaft connected to the eccentric cam via an arm, and a toothbrush attached to the rolling shaft. In an electric toothbrush configured such that the eccentric cam is rotated by the arm, the rotation of the eccentric cam is transmitted to the rolling shaft through the arm, and the rolling shaft rolls the toothbrush,
An electric toothbrush characterized by having the following configuration. (a) An elastic vibrator is connected between the eccentric cam and the arm. (b) A vibrator consists of a vibrating part and a fixed part. (c) Fixed parts are fixed directly or indirectly to the casing. (d) The vibrator has elasticity that connects the vibrating part to the fixed part so as to vibrate freely. (e) An eccentric cam and an arm are connected to the vibrating part. (f) The vibrating portion of the vibrator is vibrated by the eccentric cam, and this vibration is transmitted to the rolling shaft via the arm to roll the toothbrush. (2) It is equipped with an eccentric cam rotated by a motor, a rolling shaft connected to this eccentric cam via an arm, and a toothbrush attached to this rolling shaft. An electric toothbrush configured such that rotation of a cam is transmitted to a rolling shaft via an arm so that the rolling shaft rolls the toothbrush,
An electric toothbrush characterized by having the following configuration. (a) An elastic vibrator is connected between the eccentric cam and the arm. (b) A vibrator consists of a vibrating part and a fixed part. (c) Fixed parts are fixed directly or indirectly to the casing. (d) The vibrator has elasticity that movably connects the vibrating part to the fixed part. (e) An eccentric cam and an arm are connected to the vibrating part of the vibrator. (f) The vibrator includes a longitudinal motion transmission member in the vibrating part. (g) The eccentric cam and the arm are connected via a longitudinal motion transmission member. (h) The longitudinal motion transmission member has elasticity that transmits vibrations in the direction in which the arm rotates from the eccentric cam to the arm, and absorbs vibrations in a direction that intersects with the direction in which the arm rotates by deforming itself. . (i) The vibrator is vibrated by the eccentric cam, and the vibration of the eccentric cam is transmitted to the rolling shaft via the longitudinal motion transmission member of the vibrator and the arm, thereby rolling the toothbrush.
