ABSTRACT:
Even if the tension of the endless belt against the sliding contact member is reduced, the slip of the endless belt out of the rotary roller is prevented and the endless belt is smoothly moved. Also, since frictional resistance of the endless belt against the sliding contact member is reduced, durability of the endless belt can be substantially improved.The present running machine comprises a rotary roller23for circulatingly move an endless belt20mounted to the bedplate10and supported at a supporting plate22by a driving unit26,a sliding contact member25for guiding the sliding-contact movement of the endless belt20,a tension roller30for depressing the upper portion of the endless belt toward the lower portion, thereby making a distance of the upper portion and the lower portion smaller than the diameter of the rotary roller23,and a tension/contact roller40depressing and contacting the endless belt20to the rotary roller23.Further, the tension/contact roller40constitutes the tension roller30,a tension/contact force-regulating unit43is provided to regulate the tension/contact force of tension/contact roller40,and a position-adjusting unit50for adjusting the fore and rear positions of the sliding contact member25is provided.
