<p>A guide bush (10) has a bar member support (14) adjacent one axial end of a base (12). The bar member support (14) comprises a diametrically elastically deformable outer sleeve portion (16) integrally connected to the base (12), a plurality of inner sleeve piece members (20) disposed inside the outer sleeve portion (16), made of hard material and cooperating with each other to form a cylindrical bar member support surface (18), and an elastic member (22) for elastically holding the inner sleeve piece members (20) in the position where they form the bar member support surface (18). The elastic member (22) comprises elastic connecting elements (34) each interposed between adjacent inner sleeve piece members (20) to elastically interconnect the latter, and elastic intermediate sleeves (36) each interposed between the outer sleeve portion (16) and each inner sleeve piece member (20) to elastically support these inner sleeve piece members (20) from outside. The elastic connecting elements (34) may be formed of liquid gaskets.</p> |
