PROBLEM TO BE SOLVED: To reduce a risk of failure of a device for adjusting length of a seat cushion and obtain high-class usability.SOLUTION: A device that is disposed on a seat bottom surface of a seat cushion to adjust the length of the seat cushion by moving the seat cushion in the backward/forward direction includes an actuator that is coupled to a support section provided integrally with the seat bottom surface and an adjustment member mounted to the support section to enable displacement and slidably fitted to the seat bottom surface and that displaces the adjustment member with respect to the support section. The actuator includes an electric power driving section, a reduction gear, and a flexible spindle provided in a spindle drive of a motion conversion mechanism which is provided at an approximately central portion in a direction orthogonal to the backward/forward direction in the device and converts rotational motion of the reduction gear to linear displacement between the adjustment member and the support section.SELECTED DRAWING: Figure 3

    【課題】シートクッションの長さを調節する装置の故障リスクを低減し、かつ高級な使用感を得ること。【解決手段】シートクッションのシート底面に配置され、かつシートクッションを前後方向に移動させて、同シートクッションの長さを調節する装置はシート底面に一体的に設けた支持部と、支持部に変位可能に搭載され、かつシート底面に摺動可能に装着される調節部材とに連結されるとともに、支持部に対して調節部材を変位させるアクチュエータに関し、同アクチュエータは電力駆動部と、減速ギアと、装置において前記前後方向と直交する方向におけるほぼ中央部に設けられ、減速ギアの回転運動を、調節部材と支持部との間の線形変位に変換する運動変換機構のスピンドルドライブに可撓スピンドルを備える。【選択図】図3
