PROBLEM TO BE SOLVED: To provide a power seat slide device which can be switched from electric operation to manual operation and can be prevented from being half-locked although having a structure allowing manual operation.SOLUTION: The power seat slide device is configured to move forward and rearward using a rack 21 attached to a lower rail 11 and a pinion 22 engaged with the rack and transmit driving force of a motor 51 to the pinion 22; and therefore can be used in an electric operation mode. While, since the device does not use a slide screw, when currents are not carried to the motor 51, the pinion is rotated to rotate an output shaft of the motor 51, allowing the device to be manually adjusted. When turning off an engine of a vehicle mounted with the power seat slide device or when rescuing an occupant when currents cannot be carried to the device due to an accident, or the like, a vehicle seat can be manually moved forward and rearward.

    【課題】電動だけでなく手動操作に切替可能であり、また、手動操作可能な構造でありながら、ハーフロックを防ぐことができるパワーシートスライド装置を提供する。【解決手段】前後動は、ロアレール11に付設したラック21とそれに噛合するピニオン22を用い、このピニオン22にモータ51の駆動力を伝達する構成としているため、電動モードでの使用が可能となる。その一方、スライドスクリューを用いていないため、モータ51の非通電時には、ピニオンを回転させればモータ51の出力軸が回転し、手動調整が可能となる。本発明のパワーシートスライド装置が搭載された乗物のエンジンオフのとき、あるいは、事故により非通電状態となった際の乗員救出の場合等において、手動で乗物用シートを前後動させることができる。【選択図】 図3
