The invention relates to a lifting device for a treadmill comprising: a motor for positioning and transmitting a spindle pivotably connected to the bottom of the deck frame; a socket screwed to the spindle and movable to and fro by rotating the spindle; a T-shaped cross bar pivotably connected with the socket, the T-shaped cross bar extending between both sides of the deck frame, and two lifting rods each with one end connected to the T-shaped cross bar and with the other end pivotally connected to the front end of the base seat, thereby forming a pivot point. Accordingly, when the lifting motor is actuated to allow the socket to be displaced by rotating the spindle, the T-shaped cross bar and the lifting rods move in the desired direction. Therefore, the deck frame is movable up and down on the pivot point.
