PROBLEM TO BE SOLVED: To provide a check link structure of a swing door capable of reducing opening and moving speed of the swing door by spring force of only a forked spring member sufficiently and preventing the swing door from rebounding when opening the swing door fully. SOLUTION: Internal/external pulling-out guide slopes 10S3, 10S4 formed on terminal parts 11a, 12a sides of inner/outer side plate spring members 11, 12 of the forked spring member 10 and inclined in the direction of approaching from a middle belly part toward a terminal of the forked spring member 10, respectively, are asymmetrically formed so that they come into contact with pressure contact pieces 20, 20A opposing mutually at a fully opened position of the swing door 1 at substantially equal pressure, respectively, and reaction force R3, R4 received by the internal/external pulling-out guide slopes 10S3, 10S4 from the pressure contact pieces 20, 20A is made substantially equal to increase resultant force and ensure sufficient resistance force generated when the forked spring member 10 is pulled out from among a pair of pressure contact pieces 20, 20A in order to prevent the swing door 1 from rebounding when opening the swing door 1.
