<p>PURPOSE:To improve portability of an electric tooth brush by providing a case with a body storing part for storing one side of a body which contains a drive shaft and an operation switch of the body, a tooth brush storing part, and an opening part through which the other side of the body is protruded. CONSTITUTION:When a tooth brush 1 and a part of a body 2 are stored inside a half case 30, the tooth brush 1 is held between the opening edge of the half case 30 and a retaining rib 39 which is protruded from the half case 30, and the body 2 comes into contact with a rib 36 at one end through which a drive shaft 20 is projected and is held by an engagement of a projection 38 formed on the flange of an opening 37 through which the other end of the body 2 is projected with the of edge of a protruded base 22 of the body 2. Thus a case 3 covers the entire tooth brush 1, the drive shaft 20 and the switch 21, and protests the brush 1 from dust, the shaft 20 from damages caused by careless dropdown, and the switch 21 from waste of power of the battery by careless switch-ON. The rest part of the body 2 is exposed outside the case 3.</p> |
