PROBLEM TO BE SOLVED: To improve assemblability of a rotation device that connects a vehicle seat to a vehicle body in the state of being rotated in a turning direction.SOLUTION: A rotation device 10 that connects a vehicle seat to a floor surface (vehicle body) in the state of being rotated in a turning direction has: a rotary wheel that has an inner wheel 22 and an outer wheel 23 assembled in the state of supporting each other outside and inside so as to be mutually rotatable on the same axis; a ring-shaped driven gear 30 that is provided to one of the inner ring 22 and the outer ring 23 and that exposes a gear surface to a radial-direction side opposed to the other; and a drive unit 40 that is fixed to the other of the inner ring 22 and the outer ring 23 and configured to transmit a rotational-direction driving force by a drive gear 45 engaged with the driven gear 30.SELECTED DRAWING: Figure 3

    【課題】乗物用シートを乗物本体に対して旋回方向に回転させられる状態に連結する回転装置の組付け性の向上を図る。【解決手段】乗物用シートをフロア面(乗物本体)に対して旋回方向に回転させられる状態に連結する回転装置10であって、同軸上で互いに相対回転可能に内外で支え合う状態で組み付けられる内輪22と外輪23を有する回転輪と、内輪22又は外輪23のうちの一方に設けられ、他方と対向する径方向側に歯面を露出させる輪状の従動ギア30と、内輪22又は外輪23のうちの他方に固定され、従動ギア30と噛合う駆動ギア45によって回転方向の駆動力を伝達する構成である駆動ユニット40と、を有する。【選択図】図3
