To provide a seat rotation device which can reduce a cost by reducing the number of components and the number of assembling man-hours, can support a demand of space-saving by reducing a dimension and can easily secure an arrangement space in a seat.SOLUTION: A rotational shaft 30 is directly connected in an integrally rotatable manner to an output shaft 23 of a motor 21 by a connection part 31 on the one end side. A switching member 80 is pivotally supported so as to be able to transmit the rotational force by a spline 35 to the rotational shaft 30 between a drive member 60 and a release member 70, and is provided so as to be movable in the axial direction between a constraint release position of integrally rotating by being engaged with the release member 70 and a rotation driving position of integrally rotating by being engaged with the drive member 60.SELECTED DRAWING: Figure 1

    【課題】部品点数および組付工数の削減によりコスト低減が可能となり、寸法の小型化により省スペース化の要請にも応じることが可能となり、座席における配置スペースを容易に確保することができる座席回転装置を提供する。【解決手段】回転軸30は、その一端側の連結部31により、モーター21の出力軸23に一体に回転可能に直接連結されている。切換部材80は、駆動部材60と解除部材70との間で、回転軸30にスプライン35により回転力が伝達可能に軸支され、解除部材70に係合して一体に回転する拘束解除位置と、駆動部材60に係合して一体に回転する回転駆動位置とに、軸方向に移動可能に設けられている。【選択図】図1
