PROBLEM TO BE SOLVED: To provide a vehicular seat slide device that can suppress separation deformation of a lower rail from becoming unstable while delaying the separation deformation of the lower rail during the input of large loads.SOLUTION: A vehicular seat slide device comprises: a lower rail 2 which has a pair of first side wall parts 11 parallely arranged in a width direction, a bottom wall part 12 that connects both lower ends of both first side wall parts 11, a pair of inward expanding wall parts 13b which respectively expand inward in a width direction in which the parts approach each other from an upper ends of both first side wall parts 11, and a pair of downward expanding wall parts 13c which expand downward from tips of both inward expanded wall parts 13b; an upper rail 3 which has a main body part 17 and a pair of second flanges 16 that expand outward in a width direction in which the flanges separate from each other from the tip of the main body part 17 and further are folded back aso as to be surrounded by the first side wall parts 11 and the like; and a reinforcing member 40, connected to a rear end of the lower rail 2, which has a pair of side wall reinforcing parts 42 covering both first side wall parts 11 and a pair of inward expanding-wall reinforcing parts 43 which cover both inward expanding wall parts 13b, where a rear end of each inward expanding wall reinforcing part 43 has a notch 43a formed.SELECTED DRAWING: Figure 4

    【課題】大荷重入力時のロアレールの剥離変形を遅らせながらも、該ロアレールの変形が不安定になることを抑制できる車両用シートスライド装置を提供する。【解決手段】幅方向に並設された一対の第1側壁部11、両第1側壁部11の下端同士を接続する底壁部12、両第1側壁部11の上端から互いに近付く幅方向内側にそれぞれ張り出す一対の内延壁部13b及び両内延壁部13bの先端から下方に張り出す一対の下延壁部13cを有するロアレール2と、本体部17並びに本体部17の先端から互いに離隔する幅方向両外側に張り出して更に第1側壁部11等に包囲されるように折り返された一対の第2フランジ16を有するアッパレール3と、ロアレール2の後端に接合され、両第1側壁部11を覆う一対の側壁補強部42及び両内延壁部13bを覆う一対の内延壁補強部43を有し、各内延壁補強部43の後端には切り欠き43aが形成された補強部材40とを備える。【選択図】図4
