<p>Disclosed is a folding mechanism including two folding rollers, which are fitted in a swingable manner to a folding finger so as to hold deviated positions of a carcass band in a circumferential direction and in a meridian direction. The folding roller provided frontward of a swinging shaft prevents wheelie, and the folding roller provided rearward of the swinging shaft prevents fitting in a gap at a boundary between a bead lock segment and a bead. A swinging member (302) is supported at the leading end portion of a folding finger (301). Folding rollers (303), (304) are provided frontward and rearward of a swinging shaft (305). A swinging angle restriction member (306) is provided on a rear surface of substantially central portion of the swinging member (302) so as to restrict swinging angle within a predetermined value in the direction where the swinging member (302) moves away from the surface of the end portion of the carcass band (counter-clockwise rotation in the drawing).</p> |
