PURPOSE: To make it possible to leave open a tailgate to the fullest possible extent without entailing any contact with a load, by setting the first carrier to the roof panel side and the second carrier to the tail gate side each separately.

CONSTITUTION: When a tail gate 2 is opened in an arrow C direction, a long load 11 is lifted upward in its rear part together with the tail gate 2 and comes into a state of being pressed forward as a whole. In this case, a loading member 6 is able to rotate with the upper end of a link member 7 as a fulcrum as well as the link member 7 is able to rock with a pin 9 as a fulcrum so that a first carrier 3 can be shifted to the front of a car body with the hold of the long load 11 intact. In addition, the second carrier 4, as the loading member 6 is able to turn round with the upper end of a support member 5 as a flucrum, the second carrier 4 can give a variation in rotation at the carrier 4 for the long load 11 as required following the frontward movement of the first carrier 3.
