This is a continuation of U.S. patent application Ser. No. 10/884,443, entitled “Folding Treadmill,” filed Jan. 5, 2006. 1. Field of the Invention This invention relates to a treadmill, more particularly to a folding treadmill having a tread base movable rearward or forward relative to a base support when turning to a folded or unfolded position. 2. Description of the Related Art Treadmills are popular exercise apparatuses which permit a user to perform physical activities, such as walking, jogging or running movements, so as to exercise the cardiovascular system and the other parts of the body. Since treadmills are bulky and occupy a considerable space, it becomes a trend to design a treadmill with a foldable tread base in order to decrease the volume of the treadmill when the treadmill is stored. U.S. Pat. No. 5,899,834 discloses a foldable treadmill with a deck having a rear end that is hingedly attached to a stationary base. The treadmill comprises structures capable of performing a linear translation of a handrail relative to the deck. The handrail is automatically collapsed into alignment with the deck when the deck is rotated into a storage position. However, the collapsible design of the handrails renders the handrails unstable. Thus, when a user grips the handrails for support while walking or jogging on the treadmill, the user may lose balance and fall backward. U.S. Pat. No. 5,960,893 discloses a treadmill having a deck that is hingedly attached to a cabinet and having folding handrails which are folded into the cabinet while the treadmill is positioned into a storage position. However, the handle structures disclosed in the aforesaid patents are weak. U.S. Pat. No. 6,398,696 discloses a folding treadmill which includes a tread base, and two rollers attached respectively to two sides of the tread base and mounted respectively inside two vertical slide rails. The tread base is turnable about the axes of the rollers to move between a storage position and an operational position. Through upward movement of the rollers along the vertical slide rails, the tread base can move upward to an inclined position. However, since the rollers move only in a vertical direction, the movement of the tread base is restricted by the vertical slide rails so that the tread base moves only upward or downward while the tread base is folded or elevated to its inclined position. U.S. Pat. No. 6,110,076 discloses a folding treadmill with a console pivotally mounted about a hinge. The console can be rotated about the hinge while the tread base is placed in a storage position so that the tread base could be substantially vertical without interference between the tread base and the console. However, the construction of the console is complicated since the console must be pivotal about the hinge in order to avoid interference. While various forms of foldable treadmills have been suggested in the art, there is a need for an improved treadmill having a stable folding structure. An object of the present invention is to provide a folding treadmill including a tread base which can be moved rearward, when being folded upward, so as to move away from a console or control board mounted on an upright structure so that the tread base can be folded to a nearly vertical position without interfering with the console or control board. Another object of the present invention is to provide a folding treadmill with a stable construction which can stabilize a tread base, especially when the tread base is in a folded position. According to one aspect of the present invention, A folding treadmill comprising: a base support including a front end and a rear end; a guider provided on the base support adjacent the front end and having a slide rail extending substantially in a front-to-rear direction; a pivot member supported movably and guided by said slide rail; a tread base which includes a frame and an endless belt mounted to the frame and which is mounted pivotally to the base support through the slide rail and the pivot member to turn between a folded position and an unfolded position and to move rearward when the tread base turns to the folded position or to move forward when the tread base turns to the unfolded position; and a first roller attached to the tread base and guided and supported by the base support. According to another aspect of the present invention, a folding treadmill comprises: a base support including a front end and a rear end; a guider provided on the support base adjacent the front end and having a slide rail which extends substantially in a front-to-rear direction and which is inclined downward and rearward; a tread base including a frame and an endless belt mounted to the frame; and a coupler mounted movably on the base support and connected pivotally to the tread base and the guider so as to enable the tread base to turn relative to the support base between a folded position and an unfolded position. The coupler includes a pivot member which is supported movably and guided by the slide rail and which is connected to the tread base so that the tread base is movable rearward and downward when turning to the folded position or is movable forward and upward when turning to the unfolded position. The treadmill further includes a first roller attached to the coupler and supported movably on the base support so as to mount movably the coupler on the base support. According to still another aspect of the invention, a folding treadmill comprising: a base support including a foot structure and an upright structure extending upward from the foot structure, the foot structure having a front end and a rear end; left and right guide members mounted on the foot structure rearwardly of the upright structure and provided respectively with left and right slots which extend substantially in a front-to-rear direction; left and right pivot members mounted movably and respectively within the left and right slots for moving substantially along the front-to-rear direction; and a tread base which includes a frame and an endless belt mounted to the frame and which is mounted pivotally to the left and right guide members through the pivot members to turn between a folded position and an unfolded position and to move rearward when the tread base turns to the folded position or to move forward when the tread base turns to the unfolded position.
