Abstract
A swinging link mechanism, provided on a conveyance truck, for raising and lowering a vehicle body held on a supporting member includes a first arm having a fixed end section which is attached to the conveyance truck in a vertically rotatable manner by means of a horizontally oriented support axle, a second arm having a fixed end section supported rotatably on the free end section of the first arm and having a supporting member provided on the free end section thereof, and a third arm coupled rotatably between the conveyance truck and a prescribed position on the second arm. Third arm is caused to rotate the second arm in the opposite direction to the first arm in response to rotation of the first arm, thereby to make the lower movement path of the supporting member to extend substantially vertically. Hence, the vehicle body can be raised or lowered in a substantially vertical movement path, and the position and attitude of the vehicle body can be controlled readily, by adopting a link mechanism of a simple configuration.
