Abstract
A connecting mechanism for connecting a king pin fixed to a trailer to a fifth wheel mounted on a tractor. The connecting mechanism has a box structure in which major parts for connecting the king pin are mounted pivotally. The box structure is secured detachably to the lower face of a fifth wheel plate, so that the major parts can easily be replaced or inspected simply by a demounting of the box structure. It is possible to provide an elastic member between the fifth wheel plate and the box structure so as to absorb the impact applied to the connecting mechanism to prevent rapid wear of the parts and to improve the comfort of the driver.
