Claim:
A rail assembly for a drawer, comprising: a first rail defining a track, having an inner surface and a front end, and formed with a stopping protrusion that is disposed adjacent to said front end, that protrudes from said inner surface into said track, and that has a rear end; and a second rail mounted slidably on said first rail, slidable along said track, having a rear end, and formed with an engaging protrusion that is disposed adjacent to said rear end of said second rail and that protrudes therefrom toward said inner surface of said first rail; wherein said engaging protrusion includes a head body that has opposite top and bottom ends and that gradually reduces in cross-section from said top end to said bottom end, said bottom end of said head body being formed with a curved first nose that protrudes downwardly therefrom and that is blocked by said rear end of said stopping protrusion when said second rail is moved frontwardly to a first front position relative to said first rail; and wherein said head body is elastically deformable so as to be compressed by said rear end of said stopping protrusion to an extent that said first nose is able to slide over said rear end of said stopping protrusion when said second rail is further moved frontwardly from said first front position.
