A washer for guiding two mutually movable members has a circumferential portion including a cylindrical collar (5), of substantially the same diameter as a seat-forming aperture in one member, and a flange (6) projecting radially from the collar at one end. The central portion of washer body, spanning said one end of the cylindrical collar includes a central, thick core portion (7) proud of the flange (6) and an annular transition portion (8) extending between said core portion and said collar, the thickness of the transition portion decreasing radially from the core portion towards the collar. The annular transition portion is resilient in order to allow varying degrees of impression of the core portion (7) into the collar (5). |
