To restrain backlash of an upper rail in a vehicle longitudinal direction at lock.SOLUTION: A seat slide device 101 comprises a lower rail 103, an upper rail 105, a lever member 131, a lock member 117, an urging member 132 and an operation member 133. The upper rail 105 includes a shaft member 115 which is disposed so as to stride over left and right both side walls. The lever member 131 includes bearing parts which are provided on a pair of left and right side walls 147, respectively and engage to the shaft member 115. A pair of respective left and right bearing parts each include a surface which is in contact with the shaft member 115 at one point in a vertical direction by urging due to the urging member 132. The surface which is in contact with the shaft member 115 in one bearing part of the pair of left and right bearing parts is formed as a circular arc surface which includes a slightly larger radius than the outer diameter of the shaft member 115. The surface which is in contact with the shaft member 115 in the other bearing part is formed as a plane surface which extends in a longer direction of the upper rail 105.SELECTED DRAWING: Figure 14
【課題】ロック時におけるアッパレールの車両前後方向のガタつきを抑制する。【解決手段】シートスライド装置101は、ロアレール103と、アッパレール105と、レバー部材131と、ロック部材117と、付勢部材132と、操作部材133とを備える。アッパレール105は、左右両側壁に跨るように配置される軸部材115を有し、レバー部材131は、左右一対の側壁147にそれぞれ設けられ、軸部材115に係合する軸受部を有する。左右一対の軸受部がそれぞれ、付勢部材132による付勢によって軸部材115に上下方向の1点で接触する面を有する。左右一対の軸受部のうち、一方の軸受部における軸部材115と接触する面は、軸部材115の外径よりも僅かに大きい半径を有する円弧面として形成され、他方の軸受部における軸部材115と接触する面は、アッパレール105の長手方向に沿って延びる平面として形成される。【選択図】図14
