Patent ID: 7648773

Claim:
A connecting apparatus comprising a first machine constituent element on a first side connected to a second machine constituent element on a second side placed via a supporting axis supported by the first machine constituent element on the first side and a bearing bushing outer-engaged on the supporting axis so that the first machine constituent element and the second machine constituent element are mutually revolvable or rotatable, wherein said supporting axis is made of a contact member in which a contact surface of a contact part base material of an apparatus having a rotation contact mechanism and/or a linear contact mechanism is formed of a thermal spray membrane contact material comprising a Mo metal phase, or 5 vol % or more of a Mo metal phase and another metal phase containing one or more elements selected from the group consisting of Fe, Ni, Co, Cr, Cu, Zn and alloys thereof, as a constituent material, and said bearing bushing is constituted of a sintered material of a Fe—C-based alloy, a Fe—C—Cu-based alloy or a Cu—Sn-based alloy, said sintered material having a content of pores of 5 to 30 vol %, in which the pores are filled with a lubricating oil or a lubricant composition, or is constituted of a sintered material of a Fe—C-based alloy, a Fe—C—Cu-based alloy or a Cu—Sn-based alloy, said sintered material having a content of pores of 5 to 30 vol %, in which the pores are filled with a lubricating oil or a lubricant composition, and a solid lubricant is dispersed therein.
