The invention aims to provide a backrest connecting structure which can prevent a seat back from opening forward under a forward impact load in a vehicle and is easy to assemble. The backrest connecting structure (100) comprises first and second backrests (102 and 104) which are separated from each other in a width direction of the vehicle, and a center hinge (106) which is attached to a rear floor panel (108) and connected with the two backrests at a junction (110) between the first and the second backrests so as to enable the first and the second backrests to freely rotate. The backrest connecting structure (100) further includes an elongate fastening pin (136) which is fixed to a side wall (140) of the junction of the first seat back, protrudes towards the second backrest in the width direction of the vehicle, is inserted through the hinge into a first wall (144) of the second backrest, and is provided with a locking groove (162); and a locking bracket (138) that is fixed to the second backrest, approaches the pin from a direction perpendicular to the pin, and is clamped with the clamping groove so as to enable a positional relation between the first backrest and the second backrest to be fixed to each other.
