Claim:
A hinge comprising a metal-made first hinge member including a first attachment plate part and a first cylindrical part disposed along one side part of said first attachment plate part with at least one part of said first cylindrical part projecting forward from a front surface of said first attachment plate part, a metal-made second hinge member including a second attachment plate part and a second cylindrical part disposed along one side part of said second attachment plate part with at least a part of said second cylindrical part projecting forward from a front surface of said second attachment plate part, a metal-made hinge pin inserted in said first and second cylindrical parts, said first and second cylindrical parts having axes aligned to each other, said metal-made hinge pin adapted to relatively turnably interconnect said first and second cylindrical parts, and a synthetic resin-made bush including an insertion cylindrical part inserted between an inner peripheral surface of said first cylindrical part and an outer peripheral surface of said hinge pin and movable with respect to at least one of said first cylindrical part and said hinge pin, and a flange part formed on one end part of said insertion cylindrical part in such a manner as to project radially outward therefrom and contacted with an end face of said first cylindrical part, said flange part being interposed between mutually opposing end faces of said first and second cylindrical parts, wherein a protection cylindrical part extending in the same direction as said insertion cylindrical part from said flange part and externally inserted to an outer peripheral surface of said first cylindrical part is integrally disposed at an outer peripheral part of said flange part, and said hinge further comprising a synthetic resin-made second bush, said second bush including a second protection cylindrical part and a second flange part integrally disposed at one end part of said second protection cylindrical part and projecting radially inward of said second protection cylindrical part, said second protection cylindrical part being externally inserted to said second cylindrical part, said second flange part being contacted with an end face of said second cylindrical part, said opposing end faces of said first and second cylindrical parts with said second flange part disposed therebetween being press-contacted with each other through said flange part and said second flange part.
