Abstract: A check link structure includes a first bracket, a cam arm and a cam follower. The first bracket has a pivot support structure defining a first pivot axis. The cam arm is coupled to the first bracket for pivotal movement about the first pivot axis. The cam arm includes a cam block and a support shell. The cam block has a cam surface that includes a plurality of positioning recesses and a plurality of movement restricting lobes between adjacent ones of the plurality of positioning recesses. The support shell defines a block receiving space that non-movably retains the cam block. The cam follower has a follower surface that is configured to continuously contact the cam surface of the cam block in response to movement of one of the first bracket and the cam follower relative to the other of the first bracket and the cam follower.
