Abstract
A cushion adjustable device for a treadmill includes a base plate fixed on a horizontal portion of one of two sides of a frame of the treadmill and a movable member is slidably engaged with a groove defined in the base plate. The movable member includes a resilient roller which is in contact with an underside of the deck of the treadmill. By moving the adjustable device, the resilient roller is moved to a desired position relative to the deck so as to provide a better cushion feature of the deck. A cushion display device includes an indication member and an extension rod which is fixed to the underside of the deck so that when the deck is deformed in vertical direction, the indication member is moved in vertical direction to show the deformation of the deck in the vertical direction.
