Mechanical locking system for floor panels

A tongue adapted for being received in a sidewardly open groove of an edge portion of a floor panel, wherein the tongue, which is of an elongated shape, when received in the groove is bendable in a plane substantially parallel with a front face of the floor panel and bendable in a direction parallel to a direction in which the tongue is received in the groove, such that the tongue is at least partially resiliently displaceable in said plane and wherein the width of the tongue, which is parallel to an insertion direction of the tongue into the groove, varies in the longitudinal direction of the tongue, the longitudinal direction extending parallel to the edge portion of the floor panel and the front face of the floor panel, and the tongue, when received in the groove, includes an upper displacement surface facing the front face of the floor panel and a lower displacement surface facing a rear face of the floor panel, and the upper displacement surface or the lower displacement surface has a beveled edge in the longitudinal direction.
