The present invention relates to a joint bracket. The joint bracket greatly improves durability against an external impact of a pillar fixing bracket by a plurality of reinforcing ribs formed between an outer surface of a connection part of the pillar fixing bracket and an inner surface of a fixing body at regular intervals. A mounting bracket in which a rail member is accommodated can be vertically inclined to a certain angle according to an inclination angle of a ground surface, and thus the rail member can be inclined to a certain angle according to the inclination angle of the ground surface. |
