A vehicular seat slide device includes a lower rail, an upper rail supporting a seat above, a lock lever supported by the upper rail and configured to restrict the relative movement of the upper rail by engaging with the lower rail, a spring attached to the upper rail and biasing in such a manner that the lock lever engages with the lower rail. The spring includes a locking portion inserted in a locking hole provided at an upper edge of the upper rail and opening to a side surface of the upper rail, the locking portion is insertable into the locking hole by elastically deforming the spring body towards an inner side relative to the locking hole, the locking portion is restricted from being detached from the locking hole by being locked at a peripheral edge of the locking hole due to recovery of the elastic deformation.

Vehicular seat slide device

In a case where an engagement member is assembled on an upper rail, a second rotary shaft portion is inserted to a shaft receiving bore of a first side wall portion from an inner side of an upper rail. After the insertion, the engagement member is rotated so that the second rotary shaft portion is inserted to the shaft receiving bore of the second side wall portion. At this time, because a shaft allowable length is specified to be greater than a shaft maximum rotation length, an interruption of an insertion of the rotary shaft portion because of a contact of the second rotary shaft portion with an edge portion of the shaft receiving bore at the second side wall portion is restrained.
