PURPOSE: A method for manufacturing a link of a chain for a trolley conveyor is provided which reduces product cost by simply and safely manufacturing the link forming the chain for the trolley conveyor and reducing processes for manufacturing the link at the same time. CONSTITUTION: The method for manufacturing a link of a chain for a trolley conveyor comprises the steps of blanking an iron plate(100") having a certain thickness so as to form a processing plate(100) in which a pair of processing parts(110) with curved parts(111) which have relatively wide widths and are projected to the inner side are symmetrically connected by a connection part(120) having a relatively narrow width so that female grooves(130) are formed inside the processing plate(100); pressing the processing parts(110) of the processing plate(100) so as to form and bend the curved parts(111) to the outside; forming a support part(110') with curved parts(111') which are projected to upper and lower surfaces of the processing plate(100) by pressing the processing parts(110) of the processing plate(100) on which the curved parts(111) are formed to the outside; forming a curved surface(121) by processing an inner surface of the connection part(120) of the processing plate(100) which is symmetrically formed in a straight line shape around the support part(110'); and forming a link(100') by trimming the processing plate(100) in which the curved surface(121) is formed on the inner surface of the connection part(120).
