20120121366 | SUSPENDING MEMBER BREAKAGE PREVENTING MECHANISM IN A SPARE WHEEL HOLDING APPARATUS - A spare wheel holding apparatus includes a device for winding up a spare wheel with a suspending member. The device includes a rotation restricting plate and a rotation restricting pin having a projecting pin portion. When a winding-off force is applied to the suspending member, the rotation restricting plate abuts on the projecting pin portion, thereby stopping winding-off of the suspending member. A suspending member breakage preventing mechanism also uses the rotation restricting pin as a safety pin. If the winding-off force is larger than that in normal, the projecting pin portion is broken at a root portion, the suspending member is wound off, thereby preventing breakage. The root portion has a smaller thickness than a tip end portion of the projecting pin portion. | 05-17-2012 |
