The weight 73 is fixed to the output shaft 72. Further, the center of gravity of the weight 73 is eccentric to the output shaft 72.
　取付ケース１２は、ブラシ取付軸５２が形成されたアウターケース５０と、このアウターケース５０に取り付けられたインナーケース６０とを含む。 The mounting case 12 includes an outer case 50 in which the brush mounting shaft 52 is formed, and an inner case 60 mounted to the outer case 50.
　インナーケース６０は、電池１３が取り付けられた電池取付部分６１と、回路基板１４が取り付けられた基板取付部分６２と、振動発生装置７０が取り付けられた装置取付部分６３とを含む。 Inner case 60 includes a battery attachment portion 61 to which battery 13 is attached, a substrate attachment portion 62 to which circuit board 14 is attached, and a device attachment portion 63 to which vibration generator 70 is attached.
　アウターケース５０は、操作部材１７が取り付けられた筒状のケース本体５１を含む。ブラシ取付軸５２は、ケース本体５１の上端部分から上方に突出している。 The outer case 50 includes a cylindrical case main body 51 to which the operation member 17 is attached. The brush mounting shaft 52 protrudes upward from the upper end portion of the case main body 51.
　ブラシ取付軸５２は、筒状の軸部分５２Ａと、この軸部分５２Ａの上端部分を覆う平面部分５２Ｂとを含む。ブラシ取付軸５２の内部には、内部空間５３が形成されている。 The brush mounting shaft 52 includes a cylindrical shaft portion 52A and a flat portion 52B covering an upper end portion of the shaft portion 52A. An internal space 53 is formed inside the brush mounting shaft 52.
　平面部分５２Ｂには、同平面部分５２Ｂから上方に突出する突起部分５４が形成されている。ステインケアアタッチメント４０は、突起部分５４への取り付けおよび突起部分５４からの取り外しが可能な状態で突起部分５４に取り付けられている。 The flat portion 52B is formed with a protruding portion 54 projecting upward from the flat portion 52B. The stain care attachment 40 is attached to the projection 54 in a manner that allows attachment to the projection 54 and removal from the projection 54.
　ブラシ取付軸５２の内部空間５３には、インナーケース６０の装置取付部分６３の大部分、振動発生装置７０の電動モータ７１の大部分、出力軸７２、および分銅７３が収容されている。また、ブラシ取付軸５２の内部空間５３に振動発生装置７０が収容された状態においては、装置取付部分６３の外側面と軸部分５２Ａの内側面とが接触している。 In the internal space 53 of the brush mounting shaft 52, most of the device mounting portion 63 of the inner case 60, most of the electric motor 71 of the vibration generating device 70, an output shaft 72, and a weight 73 are accommodated. Further, in a state in which the vibration generating device 70 is housed in the internal space 53 of the brush mounting shaft 52, the outer surface of the device mounting portion 63 and the inner surface of the shaft portion 52A are in contact.
　歯ブラシ２０のケース２２は、ブラシ毛２１を保持する平板状の保持部分２３と、保持部分２３から下方に向けて延びるケース本体２４とを含む。 The case 22 of the toothbrush 20 includes a flat holding portion 23 for holding the brush bristles 21 and a case main body 24 extending downward from the holding portion 23.
　ケース本体２４の前面部分２４Ａは、上方に向かうにつれて後方に傾斜している。ケース本体２４の後面部分２４Ｂは、上方に向かうにつれて前方に傾斜している。ケース本体２４の前面部分２４Ａの傾斜度合は、ケース本体２４の後面部分２４Ｂの傾斜度合よりも大きい。このため、保持部分２３は、本体１０の中心線Ｃ１に対して後方に位置している。なお、本体１０の中心線Ｃ１は「本体ケースの中心線」に相当する。 The front portion 24A of the case body 24 is inclined rearward as it goes upward. The rear surface portion 24B of the case body 24 is inclined forward as it goes upward. The degree of inclination of the front surface portion 24A of the case body 24 is larger than the degree of inclination of the rear surface portion 24B of the case body 24.

The center line C1 of the main body 10 corresponds to "the center line of the main body case".
　ケース本体２４の内部には、内部空間２５が形成されている。この内部空間２５は、ケース本体２４の前面部分２４Ａの傾斜および後面部分２４Ｂの傾斜と同様の形状として形成されている。すなわち、内部空間２５の前方の部分の傾斜度合が後方の部分の傾斜度合よりも大きい。 An internal space 25 is formed inside the case body 24. The inner space 25 is formed in the same shape as the inclination of the front surface portion 24A of the case main body 24 and the inclination of the rear surface portion 24B. That is, the degree of inclination of the front portion of the inner space 25 is larger than the degree of inclination of the rear portion.
　ケース本体２４の内部空間２５には、ステインケアアタッチメント４０が収容されている。ステインケアアタッチメント４０の上端は、ケース本体２４において内部空間２５を形成する壁面の最上部分よりも下方に位置している。すなわち、内部空間２５の上方の部分にはステインケアアタッチメント４０が存在していない。 The stain care attachment 40 is accommodated in the internal space 25 of the case body 24. The upper end of the stain care attachment 40 is located below the uppermost portion of the wall surface forming the internal space 25 in the case main body 24. That is, no stain care attachment 40 exists in the upper part of the internal space 25.
　図１および図２を参照して、電動歯ブラシ１の動作について説明する。 The operation of the electric toothbrush 1 will be described with reference to FIGS. 1 and 2.
　歯ブラシ２０がブラシ取付軸５２に取り付けられた状態において、操作部材１７の操作によりスイッチ１６がオンされたとき、電池１３の電圧が電動モータ７１に印加される。そして、電動モータ７１の出力軸７２および分銅７３が回転することにより、電動モータ７１が振動する。この振動は、ブラシ取付軸５２を介して歯ブラシ２０およびステインケアアタッチメント４０のそれぞれに伝達される。 In a state where the toothbrush 20 is attached to the brush attachment shaft 52, when the switch 16 is turned on by the operation of the operation member 17, the voltage of the battery 13 is applied to the electric motor 71. Then, when the output shaft 72 and the weight 73 of the electric motor 71 rotate, the electric motor 71 vibrates. This vibration is transmitted to each of the toothbrush 20 and the stain care attachment 40 via the brush attachment shaft 52.
　図２～図４を参照して、ステインケアアタッチメント４０およびその周辺の構成について説明する。 The stain care attachment 40 and the configuration around it will be described with reference to FIGS. 2 to 4.
