A posture adjusting mechanism according to the present invention is used for a cargo handling device for a cargo truck in which an arm member is mounted in such a manner that it can swivel about a vertical shaft provided on an upper end portion of a pole member, such as a pole, mounted on a bed of the cargo truck upright and above a cab of the truck and in which a cargo supporting member, such as a hook, hangs from the distal end of the arm member in such a manner that it can be raised or lowered freely. The vertical shaft provided on the upper end portion of the pole member so as to swivel the arm member thereabout is made pivotal relative to a vertical axis. |
