<p>PURPOSE:To provide a structure for actuating a motor switch by using a pressing force required for pushing a brush against teeth. CONSTITUTION:A body 1 is detachably provided with a brush 2. In addition, a battery 10, a motor 3 and a switching means 4 are laid inside the body 1. Also, the body 1 has an eccentric cam 5 for converting the rotation of the motor 3 to reciprocating motion, a link member 6 and a drive shaft 7 continuous thereto for mounting the brush 2. A support roller 8 for bearing the drive shaft 7 in such state as capable of free motion is also provided, together with a holding roller 9 for retaining one end of the shaft 7 in such state as capable of oscillation about the support roller 8, in a direction orthogonal with a moving direction. One end of the shaft of the roller 9 is linked to the switching means 4.</p> |
