PROBLEM TO BE SOLVED: To provide a seat rotating device which enables cost reduction by reduction of the number of components, achieves improvement of the quality of shaft peripheral components, and can prevent damage of the shaft peripheral components and breakage of a cable while achieving downsizing and weight reduction.SOLUTION: A seat rotating device includes: a motor 51; a drive member 60 which rotates an underframe 11 of a seat 10; a release member 70 which releases the seat 10 restrained by a lock mechanism 40; and a switch member 80 which selectively transmits output of the motor 51 to the drive member 60 or the release member 70. The switch member 80 is pivotally supported between the drive member 60 and the release member 70 so that a rotation force can be transmitted to a rotary shaft 53 by a spline and is provided so as to move axially to a restraint release position where the switch member 80 engages with the release member 70 to integrally rotate therewith and a rotation drive position where the switch member 80 engages with the drive member 60 to integrally rotate therewith.SELECTED DRAWING: Figure 1

    【課題】部品点数の削減によるコスト低減が可能となり、軸回り部品の品質向上を図ることができ、小型化や軽量化を実現しつつ、軸回り部品の破損やケーブルの破断を防止することができる座席回転装置を提供する。【解決手段】モーター51と、座席10の台枠11を回転させる駆動部材60と、ロック機構40による座席10の拘束を解除する解除部材70と、モーター51の出力を駆動部材60または解除部材70に選択的に伝達する切換部材80と、を有する。切換部材80は、駆動部材60と解除部材70との間で、回転軸53にスプライン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
