- the oar components of the present invention are connected to the rotating shaft through the bearings and unilateral bearings. In this way, when the oar is rotated in one direction (it is actually the equivalent of swinging due to the small angle of rotation), the oar drives the rotating plate to rotate through the bearings and unilateral bearings.
- the present invention adopt two oar components, which are respectively connected to the unilateral bearing and the end portion of the rotating shaft in universal joining way. In this way, two oar components can be used simultaneously, but also one can be used only.
- the present invention can not only well simulate the rowing action, but also realize various simulation effects.
- a seat back is added at the rear part of the cushion plate, and the seat back is pivoted to the rear end of the cushion plate by a torsion spring, such to provide support to the back of the rowing athlete in the process of simulating rowing, greatly improving the effect of simulating rowing.
- the cross bars are sleeved with cylindrical rollers, the cylindrical roller can roll when used, providing massage on the back of the rowing athlete, and increasing health care of the product.
