整機構を有するベルト伝動装置。[Claims for Utility Model Registration] A driving and driven pulley consisting of a pair of rotating shafts that are parallel to each other, toothed pulleys supported by the rotating shafts, and and a timing belt for transmitting power, and the driving pulley includes a first pulley member rotatably supported by the rotating shaft, and a timing belt eccentrically disposed on the outer periphery of the first pulley member with respect to the axis of the first pulley member. a substantially ring-shaped second pulley member that is arranged so as to be able to engage with the timing belt and has a tooth portion on its outer periphery that engages with the timing belt; and an endless high-tensile-strength flexible member that rotationally connects both of the pulley members. The endless high tensile strength flexible member is provided with a plurality of engaging protrusions equally spaced in the length direction, while the endless high tensile strength member is provided on the outer periphery of the first pulley member and the inner periphery of the second pulley member, respectively. A plurality of engagement recesses that engage with the engagement protrusions of the flexible member to connect the flexible member to the pulley member, and a plurality of guide grooves that guide the flexible member on the sides of the engagement protrusions. The flexible member is provided at predetermined angular intervals in the circumferential direction, and the engaging protrusions of the flexible member are engaged with the engaging recesses of the first and second pulley members alternately and over the entire circumference. A belt transmission device having an automatic tension adjustment mechanism.
