To suppress deformation volume of a lock component when receiving an impact load in a cross direction, and achieve stability and improvement of lock strength.SOLUTION: A lock component 117 is attached to an upper rail 105 at an oscillation fulcrum part 151, and comprises, at an end part on a rear side of the oscillation fulcrum part 151, five lock teeth 125b (125b1 to 125b10) along a cross direction on both of left and right sides. The lock component comprises, in left and right lower inside walls 103e of a lower rail 103, a plurality of lock grooves 127 in the cross direction with which the lock tooth 125b engages from below. The plurality of lock grooves 127 have groove widths in the cross direction which are equal to each other in design. A width L1 in the cross direction of the lock tooth 125b3, which is positioned on the right side of the center in the cross section, of the plurality of lock teeth 125b is largest among widths of other lock teeth in the cross direction, and a width L2 of the lock tooth 125b8, which is positioned on the left side of the center in the cross direction, of the plurality of lock teeth 125b, is second largest after the width L1 of the lock tooth 125b1.SELECTED DRAWING: Figure 14

    【課題】前後方向に衝撃荷重を受けたときに、ロック部材の変形量を抑制してロック強度の安定と向上を図る。【解決手段】ロック部材117は、アッパレール105に揺動支点部151で取り付けられ、揺動支点部151の後方側の端部に、左右両側に前後方向に沿って五つのロック歯125b(125b1〜125b10)を備える。ロアレール103の左右のロア内側壁103eには、ロック歯125bが下方から係合するロック溝127を前後方向に複数備える。複数のロック溝127は、前後方向の溝幅が設計上互いに等しい。複数のロック歯125bのうち前後方向中央の右側に位置するロック歯125b3の前後方向の幅L1が、他のロック歯の前後方向の幅に比較して最も大きく、複数のロック歯125bのうち前後方向中央の左側に位置するロック歯125b8の幅L2が、ロック歯125b1の幅L1の次に大きい。【選択図】図14
