Abstract
Abstract An anti-lifting mechanism which utilizes a braking torque during braking of a rear wheel of a motor vehicle to prevent the vehicular body frame from being lifted up at the rear portion thereof. The anti-lifting mechanism includes a torque link arrangement for transmitting the braking torque to the vehicular body, the torque link arrangement comprising a substantially straight first torque transfer member, a substantially straight second torque transfer member and a link member interposed between the first and the second torque transfer members to interconnect the torque transfer members. Because the torque link arrangement can be constituted as a bent path, its constituent members can be disposed a selective arrangement, and the unsprung load of a shock absorber is reduced.
