PROBLEM TO BE SOLVED: To provide an inexpensive driving device that transmits driving force with one motor and a reduction gear through a differential lock of a differential device because a driving device built in a bearing has a fault of becoming expensive due to the production of an exclusive motor and reduction gear required for and adapted to each wheel although a driving device for driving and rotating wheels of a conventional wheelchair is formed to be foldable while having motors and reduction gears built in bearings of the respective right and left wheels and including a control panel for regulating the right and left driving force.SOLUTION: A driving device D includes, at a motor 7, a motor shaft 9 having a hypoid pinion 10 a hypoid gear 11 meshed with the motor shaft 9 a first gear 13 rotatably pivoted to and built in the hypoid gear 11 a second gear 14 orthogonally meshed with the first gear 13 and a differential device S transmitting the rotation of the second gear 14 to a large wheel 2 as an output shaft 15. A differential lock clutch 30 is provided at this differential device S.COPYRIGHT: (C)2014,JPO&INPIT【課題】従来の車椅子の車輪を駆動回転させる駆動装置は、左右の各車輪の軸受にモータと減速機を内蔵して、左右の駆動力を調整する制御盤を備えて、折り畳み可能にしている。しかし、軸受に内蔵する駆動装置は、各車輪に必要で車輪に合わせた専用のモータと減速機を製作しているため、高価になる欠点があった。本発明では、1台のモータと減速機で差動装置のデフロックを介して伝達する安価な駆動装置を提供する。【解決手段】本発明の駆動装置Dは、モータ7にハイポイドピニオン10を備えたモータ軸9と、該モータ軸9に噛合うハイポイドギヤ11と、該ハイポイドギヤ11に回転自在に軸着して内蔵された第1歯車13と、該第1歯車13と直交して噛合う第2歯車14と、該第2歯車14の回転を出力軸15として大車輪2に伝達する差動装置Sを備え、この差動装置Sにデフロッククラッチ30を備える構成とする。【選択図】図2
