This invention provides an iron-based sinter multilayer wound bush having excellent cost effectiveness, a method for manufacturing the same and an operating machine connecting apparatus. The iron-based sinter multilayer wound bush comprises an iron-based sinter sliding material layer, which , while lowering the coefficient of friction, can realize excellent antiseizure properties and abrasion resistance, can impart self-lubricity to increase grease-supply intervals or eliminate the need to supply grease, firmly sinter-bonded onto a back metal steel plate. The iron-based sinter multilayer wound bush is characterized by comprising a back metal steel plate, an iron-based sinter sliding material layer sinter-bonded onto the back metal steel plate, a diffusing layer of iron-based alloy particles provided near the bonded interface of the iron-based sinter sliding material layer and the back metal steel plate, and a Cu alloy phase provided around the bonded interface and extended on the bonded interface side. |
