To provide one example of a driving device which can be applied to a sheet for a vehicle including a movable part that oscillates and is displaced through a taumel type speed reduction mechanism.SOLUTION: A driving device includes: a planetary gear mechanism 14 which constitutes a speed reduction mechanism for driving that reduces speeds of rotation output from electric motors 11 and 12 and outputs the rotation; a recliner which reduces a speed of rotation output from the planetary gear mechanism 14 and transmits the rotation to a back frame; a speed reduction mechanism 23 for detection which is the speed reduction mechanism 23 for detection which reduces the speeds of the rotation output from the electric motors 11 and 12 and transmits the rotation to rotation bodies 21 and 22, and reduces the speed so that rotation angles of the rotation bodies 21 and 22 become less than 360 degrees; and detection sections 24A and 24B which detect the rotation angles of the rotation bodies 21 and 22.SELECTED DRAWING: Figure 8

    【課題】 タウメル方式の減速機構を介して揺動変位する可動部を備える乗物用シートに適用可能な駆動装置の一例を開示する。【解決手段】 電動モータ11、12から出力された回転を減速して出力する駆動用減速機構をなす遊星歯車機構14と、遊星歯車機構14から出力された回転を減速してバックフレームに伝達するタウメル減速機構に構成されたリクライナと、電動モータ11、12から出力された回転を減速して回転体21、22に伝達する検出用減速機構23であって、当該回転体21、22の回転角度が360度未満となるように減速する検出用減速機構23と、回転体21、22の回転角を検出する検出部24A、24Bとを備える。【選択図】 図8
