An automobile seat slide unit includes two slide rail assemblies disposed on respective sides of a seat. Each of the slide rail assemblies has a lower rail to be secured to a vehicle floor and an upper rail to be secured to the seat and slidably mounted on the lower rail for adjusting the position of the seat in a direction longitudinally of a vehicle body. The lower rail has a generally flat bottom wall, two outer side walls extending upwardly from respective side edges of the bottom wall, and two inner side walls extending laterally inwardly and downwardly from respective upper edges of the outer side walls to present a shape generally similar to an inverted figure "U". On the other hand, the upper rail has a generally flat upper wall, two inner side walls extending downwardly from respective side edges of the upper wall, and two outer side walls extending laterally outwardly and upwardly from respective lower edges of the inner side walls to present a shape generally similar to the shape of a figure "U". The inner side walls of the lower rail are received within respective guide clearances each defined between the inner and outer side walls of the upper rail, while the outer side walls of the upper rail are received within respective guide clearances each defined between the inner and outer side walls of the lower rail. A plurality of spherical members are interposed between the upper and lower rails at lower corners thereof, while a plurality of rollers are interposed between upper edges of the outer side walls of the upper rail and laterally extending portions of the inner side walls of the lower rail.
