Device for guiding the relative displacement of two bodies

A device for the guidance of two bodies relative to one another, comprising a slide with a female member and a male member contained within the said female member, being supported on the latter, a row of elements for fixing one of the members to one of the bodies and another row of elements for fixing the other member to the other body, whereby those rows are substantially parallel and spaced by a given distance limited by the assembly regulations which must be observed in order to obtain a satisfactory guidance, whereby the fixing elements of at least one of the said rows each comprises a threaded rod and at least one nut cooperating with the said rod, wherein at the position of each of the said threaded rods a recess is made in the body corresponding to the said row of threaded rods issuing, in order to permit the introduction of the nut or nuts into the recess, into one face of the said body which is perpendicular to the fixing face of the member fixed to the said body, is delimited by a volume of material wherein is provided an orifice issuing into the fixing face and containing the nut or nuts, the said orifice permits the introduction of the end of the threaded rod into the recess but prevents the removal of the nut or nuts from the recess via the fixing face.
