ABSTRACT:
A pulley holder for rotatably supporting a pulley around which a belt is wound, in which the pulley holder includes a shaft having a shaft body for supporting the pulley and a projection at least one end of the shaft body in its axial direction, and a holder body having a bearing for supporting the shaft body, and a fitting part for fitting the projection. Since the projection is biased from an axis of the shaft body, once the projection is fit into the fitting part, the shaft body would not rotate around the axis. Accordingly, a friction wear of the bearing of the holder body is prevented and thus a shift in conveying a carriage is prevented.
