Abstract:
1. A belt attachment jig comprising: a jig body positioned such that a side surface thereof faces a side surface of a pulley, and a belt guide portion located at one end of the side surface of the jig body and protruding along a circumference of the pulley, and having, in a surface on a base side thereof, a holding surface for holding a belt, the belt guide portion being configured to guide the belt onto the holding surface and lead the belt out to a lateral side of the pulley, when fitted in a pulley groove of the pulley, and the belt attachment jig being used for wrapping the belt around at least two pulleys in a tight tension and attaching the belt to one of the at least two pulleys by fitting the belt guide portion in the pulley groove of the one pulley and holding the belt on the holding surface, with the belt looped over the other pulley, and fitting the belt in the pulley groove by moving the belt attachment jig in a pulley rotational direction together with the belt as the pulley is rotated, wherein the holding surface has a top at a middle portion of a part connecting the jig body the belt guide portion, and is tilted obliquely downward in radial directions from the top so that an inner circumferential surface of the belt faces the jig body, and the holding surface also serves as a detachment preventing portion that is curved in an inverted U shape in a convex manner away from the jig body along a lead-out direction of the belt to prevent the belt from being detached toward the jig body.
