Abstract
An improved vibration absorbing structure of treadmill is comprising two connecting rods on both sides of the support board; a tube on each angled tube with one insertion unit on either side of the tube; an angled tube is fixed on each connecting rod and this angled rod is connected to a tube with an elastic unit and an insertion unit; the tube is connected with a cap by a fixing bolt with another elastic unit in between. Therefore, the supporting board can send its vibrations to the two tubes and the vibrations can be effectively absorbed by the two elastic units at both sides of the two tubes.
