PROBLEM TO BE SOLVED: To provide a seat adjustment device capable of further being downsized in the width direction.SOLUTION: A slide mechanism M2 includes: a direction conversion gear box 30 which has a helical gear 34 rotatably driven through a torque cable 13 on a drive unit, a helical gear 33 engaged with the helical gear 34 therebelow, and a direction conversion gear housing 31 storing the gears in a position deviated in the width direction from a lower rail 1; a slide drive gear box 20 which has a helical gear 23 rotatably driven to the helical gear 33, a helical gear 22 engaged with the helical gear 23 therebelow, and a slide drive gear housing 21 storing the gears in a position in the width direction of the lower rail 1; and a reed screw 12 which is integrally rotated with the helical gear 22. The direction conversion gear housing 31 and the slide drive gear housing 21 are integrally provided with a pair of supported protrusions 32 and support pieces coaxially connected to the helical gear 33 in a relatively rotatable manner, respectively.SELECTED DRAWING: Figure 3

    【課題】幅方向においてより小型化することができるシート調整装置を提供する。【解決手段】スライド機構M2は、駆動装置にトルクケーブル13を介して回転駆動されるハスバ歯車34、ハスバ歯車34の下方でこれに噛合するハスバ歯車33及びロアレール1に対して幅方向にずれた位置でそれらを収容する方向変換用ギヤハウジング31を有する方向変換用ギヤボックス30と、ハスバ歯車33に回転駆動されるハスバ歯車23、ハスバ歯車23の下方でこれに噛合するハスバ歯車22及びロアレール1の幅方向の位置でそれらを収容するスライド駆動用ギヤハウジング21を有するスライド駆動用ギヤボックス20と、ハスバ歯車22と一体回転するリードスクリュ12とを備え、方向変換用ギヤハウジング31及びスライド駆動用ギヤハウジング21には、ハスバ歯車33と同軸で相対回動自在に連結する一対の被支持突部32及び支持片がそれぞれ一体に設けられている。【選択図】図3
