A stabilizer mounting member comprising a tubular cushion member and a bracket member, wherein the tubular cushion member has lobe portions projecting radially outwardly at its opposite axial ends, while the bracket member has corresponding recesses which receive these lobe portions, wherein the projecting height of the lobe portions is greater than the depth of the recesses so that the cushion member is more tightly gripped at its opposite axial ends than at its middle portion so as to prevent entry of mud, sand or the like between the cushion member and the stabilizer.
