A bearing bushfor use in a toggle has a cylindrical metallic base materialand a solid lubricantembedded in the metallic base material, and the metallic base materialhas dead end groovesformed in a cylindrical inner peripheral surface, an annular grooveformed in the cylindrical inner peripheral surface, and circular holesandas well asandformed in each of a pair of semicylindrical inner peripheral surfacesandadjacent to each other in an axial direction X and two pairs of semicylindrical inner peripheral surfacesandsandwiching the pair of semicylindrical inner peripheral surfacesandin a circumferential direction R and adjacent to each other in the axial direction X in each pair.

Bearing bush for use in toggle

High-strength brass alloy having superior wear maintains single-structure &#x3b2; phase and Fe&#x2014;Cr&#x2014;Si-based intermetallic compounds dispersed in the &#x3b2; phase. A high-strength brass alloy for sliding member comprises Zn from 17% to 28%, Al from 3% to 10%, Fe from 1% to 4%, Cr from 0.1% to 4%, Si from 0.5% to 3%, mass ratio, and the remnant including Cu and inevitable impurities. The high-strength brass alloy has structure in which the matrix shows single-phase structure of &#x3b2; phase and Fe&#x2014;Cr&#x2014;Si-based intermetallic compounds are dispersed in the &#x3b2; phase. The high-strength brass alloy for sliding member has the structure in which the matrix shows single-structure of &#x3b2; phase and hard Fe&#x2014;Cr&#x2014;Si-based intermetallic compounds are dispersed in the &#x3b2; phase. Thus the hardness is increased and wear resistance is improved.
