A tubular journal member of predetermined inner diameter and composed of material having a predetermined elasticity is provided. An element to be journaled in the journal member has an outer circumferential surface of a given diameter and at least one circumferential bead projecting from the surface by a predetermined amount. The bead is inserted through the journal member and the diameters, the predetermined amount of projection and the elasticity of the material of the journal member are so correlated that insertion of the bead through the journal member effects calibration of the inner diameter of the latter with the material of the journal member elastically yielding to the bead and thereupon returning to define with the outer circumferential surface a predetermined amount of play.
