Claim 9:
10. A rowing machine, comprising a rotating wheel (100) and a main shaft (200), wherein the main shaft (200) is arranged on the rotating wheel (100) in a penetrating manner;
a turntable part (110) and a resilience part (120) are axially distributed on the rotating wheel (100);
the turntable part (110) is connected to the main shaft (200) through a one-way bearing (111), so that the rotating wheel (100) drives the main shaft (200) to rotate in one way;
a volute spring (121) is arranged on the resilience part (120); an inner end of the volute spring (121) is fixed on the resilience part (120), and an outer end is fixed on a volute reel (122); the rotating wheel (100) and the volute reel (122) are relatively rotatable, so that the volute spring (121) is tightened to generate a resilience force for rotary resetting of the rotating wheel (100);
one end of the main shaft (200) is provided with a resistance mechanism used for preventing the rotating wheel (100) from rotating; and a handheld mechanism used for pulling the rotating wheel (100) to rotate is arranged on the turntable part (110).
