Claim:
1. A belt attachment jig which is used for wrapping a belt around at least two pulleys in a tight tension, by being attached to one of the pulleys, comprising: a belt guide portion of which a back surface is curved along its longitudinal direction; a jig body provided at one end of the belt guide portion in the longitudinal direction and offset on one side of the belt guide portion in a width direction of the belt guide portion orthogonal to the longitudinal direction, wherein the jig body includes a contact portion which is arranged on a lateral side of the belt guide portion in the width direction and which extends in a direction to which the back surface of the belt guide portion faces, and a twisting preventing plate which protrudes from the contact portion along the longitudinal direction of the belt guide portion, the twisting preventing plate is offset from the belt guide portion in the width direction of the belt guide portion, when viewed in a direction orthogonal to the longitudinal direction and the width direction of the belt guide portion, a space is formed between the twisting preventing plate and the belt guide portion in the width direction of the belt guide portion, and the belt is wrapped on a surface of the belt guide portion, with the back surface of the belt guide portion contacting with an outer circumferential surface of the one of the pulleys, and the belt is brought to pass the space and is sandwiched between the twisting preventing plate and one of side surfaces of the one of the pulleys in a rotational axis direction of the one of the pulleys so as to be held with an inner circumferential surface of the belt facing the one of the pulleys.
