To provide a slide structure of a vehicle seat in that a slider can be mounted on a fixed rail while maintaining the strength of a reinforcement plate.SOLUTION: A slide structure of a vehicle seat includes: a movable rail fixed to the vehicle seat; a fixed rail 1 that supports the movable rail in a linearly movable manner and is fixed to a vehicle body; a slider interposed between the movable rail and the fixed rail 1; and a reinforcement plate 5 that is integrally fixed to a lower surface 1s1 of the fixed rail 1 and has a screw hole 5a with a female screw part 5a1. The fixed rail 1 has a first through hole 1d that is concentric with the screw hole 5a and has a diameter larger than a root diameter of the female screw part 5a1. The slider has a large diameter second through hole 3b2 that is concentric with the first through hole 1d. The slide structure further includes a pin 6 having: a shaft part 6c with a male screw part 6c1, which is inserted in the first through hole 1d and screwed to the female screw part 5a1; and a head part 6a with a diameter larger than that of the second through hole 3b2 in that a peripheral edge part of the second through hole 3b2 is sandwiched between the fixed rail 1 and itself by fastening the male screw part 6c1 into the male screw part 5a1.SELECTED DRAWING: Figure 5
【課題】補強板の強度を維持しつつ固定レールにスライダを取り付けることができる乗り物用シートのスライド構造を提供する。【解決手段】乗り物用シートに固定された可動レールと可動レールを直動可能に支持し車体に固定された固定レール1と可動レールと固定レール1との間に介装されたスライダと、固定レール1の下面1s1に一体的に固定され雌ねじ部5a1を有するねじ孔5aを有する補強板5とを備える。固定レール1は、ねじ孔5aと同芯で雌ねじ部5a1の谷径より大径の第1貫通孔1dを有し、スライダは、第1貫通孔1dと同芯で大径の第2貫通孔3b2を有する。さらに第1貫通孔1dに挿通され雌ねじ部5a1に螺合する雄ねじ部6c1を有する軸部6c及び第2貫通孔3b2より大径で、雄ねじ部6c1の雌ねじ部5a1への締め付けで第2貫通孔3b2の周縁部を固定レール1との間に挟持する頭部6aを有するピン6を備えた。【選択図】図5
