To provide an autonomously travelling cleaner having a wheel with a driving device in which the size of a wheel unit can be reduced.SOLUTION: An autonomously travelling cleaner includes: a cleaner body; a driving wheel 3 rotated by the drive of a travelling motor 3m, and a speed reduction mechanism for reducing the speed of the drive of the travelling motor 3m and transmitting the reduced speed to the driving wheel. The speed reduction mechanism includes a pinion gear 31, a first eccentric gear that meshes with the pinion gear 31, a planet gear 34 rotatably supported by the first gear through a bearing, and an outer gear 37 that meshes with the planet gear 34, and is fixed to the body part. The driving wheel 3 is rotated by the rotation of the planet gear 34. The shaft of the travelling motor 3m and the driving wheel 3 are coaxially arranged. The travelling motor 3m and the speed reduction mechanism are accommodated inside the driving wheel 3.SELECTED DRAWING: Figure 7
【課題】車輪ユニットの小型化が可能な駆動装置付き車輪を有する自律走行型掃除機を提供する。【解決手段】掃除機本体と、各走行モータ3mの駆動でそれぞれ回動される駆動輪3と、前記走行モータ3mの駆動を減速して前記駆動輪に伝える減速機構とを備え、前記減速機構は、ピニオンギヤ31と、前記ピニオンギヤ31に噛み合う偏芯した第1の歯車と、前記第1の歯車に軸受を介して回転自在に支持される遊星歯車34と、前記遊星歯車34と噛み合い、前記本体部に対して固定されるアウターギヤ37とを有し、前記駆動輪3は、前記遊星歯車34の自転により回転している。また、前記走行モータ3mの軸と前記駆動輪3は同軸上に配置される。また、前記走行モータ3mおよび前記減速機構は前記駆動輪3の内側に収納される。【選択図】図7
