Abstract: A reciprocating transmission structure of an exercise machine, mounted to a frame of the exercise machine, includes a first reciprocating member, a second reciprocating member, a main rotating wheel, a first link, a second link, and a resistance wheel. The first reciprocating member reciprocally moves with a first reciprocating pivot portion as its axis. The second reciprocating member reciprocally moves with a second reciprocating pivot portion as its axis. The first link and the second link drive the main rotating wheel to rotate with a rotating shaft as its axis. The main rotating wheel drives the resistance wheel to rotate. After the first reciprocating member and the second reciprocating member move reciprocally, the resistance wheel can be driven to rotate by the cooperation of various components. The exercise machine is suitable for performing exercises related to reciprocating movement, and the operation is easier.
