PROBLEM TO BE SOLVED: To provide a seat lifter device for a vehicle capable of stably supporting a seat even at endpoint positions of a seat adjustment range.SOLUTION: A rotation controller 21 includes a rotation regulation mechanism having: a ratchet wheel rotating in unison with a rotary shaft 22 of a pinion gear; and lock members for being engaged with the ratchet wheel and thereby regulating the rotation of the rotary shaft 22. The rotation controller 21 further includes a rotation range restriction mechanism 81 for restricting the rotation range of the rotary shaft 22. The rotation range restriction mechanism 81 includes: a pair of regulation protrusion portions 83 (83a, 83b) provided at a first support member 23 for supporting the lock members, so as to be circumferentially spaced apart from each other; an engaging pin 85 provided at the ratchet wheel; and a ring member 80 provided between both regulation protrusion portions 83, and having an engagement protrusion portion 82 and an engagement groove 84 into which the engaging pin 85 is inserted.SELECTED DRAWING: Figure 21

    【課題】シート調整範囲の端点位置においても安定的にシートを支持することのできる車両用シートリフター装置を提供すること。【解決手段】回転制御装置21は、ピニオンギヤの回転軸22と一体に回転する爪車と当該爪車に噛合することにより回転軸22の回転を規制するロック部材とを有した回転規制機構を備える。また、回転制御装置21は、回転軸22の回転範囲を制限する回転範囲制限機構81を備える。そして、回転範囲制限機構81は、ロック部材が支持された第1支持部材23に設けられた周方向に離間する一対の規制突部83(83a,83b)と、爪車に設けられた係合ピン85と、両規制突部83の間に配置される係合突部82及び係合ピン85が挿入される係合溝84を有したリング部材80と、を備える。【選択図】図21
