Claim:
A hinge with catch comprising a skeleton side attaching member which can be attached to a skeleton; a door side attaching member which can be attached to a door; an inner and an outer link whose opposite ends are turnably connected to said skeleton side attaching member and said door side attaching member, respectively, so that said door side attaching member is turnably connected to said skeleton side attaching member between a closed position and an open position; an abutment member disposed generally in parallel relation to rotation axes of said inner and outer links and opposite ends of said abutment member are turnably supported by selected one of said inner and outer links; and biasing means for turnably biasing said door side attaching member through said abutment member and said selected link, by one end of said biasing means which is in abutment with said skeleton side attaching member and the other end thereof which is in abutment with an outer peripheral surface of said abutment member, wherein said abutment member is formed as a shaft and includes an enlarged-diameter part having a circular cross section and fitting shaft parts having a circular cross section, the outside diameter of said fitting shaft parts being smaller than that of said enlarged-diameter part, said fitting shaft parts formed coaxially on said enlarged-diameter part; said selected link is provided at opposite sides thereof in the direction of the rotation axis with one pair of projection pieces which are placed in opposing relation in the direction of the axis of said abutment member; each of said projection pieces is provided with a cutout recess respectively, said cutout recess being formed such that said fitting shaft parts of said abutment member can be turnably inserted into said recesses through open parts thereof until reach bottom parts of said cutout recesses; said fitting shaft parts are pressed against said bottom parts of said cutout recesses by biasing force of said biasing means; and, opposite end faces of said enlarged-diameter part of said abutment member are abutted with said pair of projection pieces, thereby said abutment member is prohibited from escaping in the axial direction thereof through said cutout recesses.
