Title:
BELT DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/024977
Kind Code:
A1
Abstract:
In the present invention, dislodging of a belt is prevented even when there is slack in a fastening member that secures a movement-side pulley for adjusting an inter-axial distance. An adjustment mechanism that adjusts an inter-axial distance between a first pulley and a second pulley is provided with a support member to which the first pulley is provided, first and second long holes provided in an arm part body, first bolts that are inserted into the first long holes and that fasten the support member to the arm part body, and second bolts that are inserted into the second long holes and that fasten the support member to the arm part body. The first long holes have a first length that enables the support member to move toward the second pulley until the inter-axial distance reaches a distance at which the belt can be wound between the first and second pulleys. The second long holes have a second length that retains the inter-axial distance at a distance such that the state in which the belt is wound between the first and second pulleys is not dislodged.
