Claims

[Claims for Utility Model Registration] A slide plate that can be positioned in three stages by sliding to an intermediate position, a first position, and a second position in the opposite direction to the first position; Based on the first
a rotating body that rotates when in the second position and reversely rotates when in the second position; a substrate having a pattern for a motor positive terminal, a pattern for a motor negative terminal, a pattern for a battery positive terminal, and a pattern for a battery negative terminal; , When the rotating body rotates, it is elastically deformed, thereby providing electrical continuity between the motor positive terminal pattern and the battery positive terminal pattern, as well as electrical continuity between the motor negative terminal pattern and the battery negative terminal pattern. a first contact piece that is elastically deformed when the rotating body rotates in the reverse direction, and conducts the motor positive terminal pattern and the battery negative terminal pattern, and connects the motor negative terminal pattern and the battery negative terminal pattern; A second contact piece electrically connected to the positive terminal pattern; and a plastic motor for driving a toothbrush that is driven when the first contact piece is elastically deformed and reversely driven when the second contact piece is elastically deformed. , electric toothbrush.
