を目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved electric toothbrush, and an object of the present invention is to provide an electric toothbrush that is easy to grasp the direction of the brush handle, has a non-slip toothbrush body, and is comfortable to use. purpose.

−以下本発明の一実施例を図面１こより詳述する。- Hereinafter, one embodiment of the present invention will be described in detail with reference to drawing 1.

１は内部に電池やモータ、ローリング駆動機構等を収納
した歯ブラシ本体で、合成樹脂により形成されており、
この歯ブラシ本体１の上端より突出した駆動軸（図示せ
ず）にブラシ柄４の基端が着脱自在に連結される。1 is the toothbrush body that houses the battery, motor, rolling drive mechanism, etc. inside, and is made of synthetic resin.
The base end of the brush handle 4 is detachably connected to a drive shaft (not shown) protruding from the upper end of the toothbrush body 1.

従ってブラシ柄４は歯ブラシ本体１に対して反転的にロ
ーリング駆動されるものであり、ブラシ柄の上端側部に

有する。2 is a recess formed on the surface of the toothbrush body 1,
When the brush handle 4 is normally attached to the toothbrush body 1, there are marks on the circumferential surface of the toothbrush body 1 corresponding to the side where the brush 3 is installed and the opposite side of the side where the brush 3 is installed in the longitudinal direction of the brush handle 4. As shown in FIG. 3, it has a spherical shape recessed at right angles to the surface of the toothbrush body 1.

５はスイッチであって、ブラシ３植設がわの凹所２列に

有する。As described above, the present invention has a cylindrical toothbrush body and a spherical recess on the outer circumference, so when you hold it, there is no corner on the outer circumference of the toothbrush body, making it easy to fit in your hand. Moreover, it has the advantage that one spherical recess allows you to comfortably insert your fingertips, makes your hand comfortable, and prevents slipping.In addition, there are multiple recesses intermittently in the longitudinal direction of the toothbrush body. Since it is recessed in the toothbrush body, it has the advantage of being able to prevent slipping in the longitudinal direction of the toothbrush body.Moreover, it is straight and discontinuous in the longitudinal direction, which is the direction in which the toothbrush body and the brush handle are connected, at predetermined positions in the circumferential direction of the toothbrush body. Since the recess is formed in the toothbrush body, it is possible to grasp the direction of the toothbrush body when connecting the brush handle to the toothbrush body, and therefore, the toothbrush body and the brush handle can be easily connected and connected by matching their directions. It has the effect that it can.
