<p>PURPOSE: A treadmill is provided to save driving energy for the rotation of a running belt by minimizing the friction resistance between the running belt and a support deck. CONSTITUTION: A treadmill comprises a mainframe(100); a running belt(400) which is installed within the mainframe, and rotated in connection with rotation of a support roller through the operation of a driver; and a pair of support decks(500) on right and left sides for supporting the running belt in case the pressure is applied from the upper side to the upper surface of the running belt, by being positioned in the inner space of the running belt. The support decks are installed in a movable manner along a guide rail which is installed on the mainframe in connection with the running operation of a user and the rotation of the running belt.</p> |
