<p>Disclosed is a vehicle body top structure for enhancing the rigidity and strength of the intersections of side rails (32) and a front rail (22). The vehicle body top structure (13) is provided with left and right side rails (32) provided so as to extend in the front-rear direction at the top part of a vehicle body side part (16), and a front rail (22) extending left and right, one end part (57) of which is joined to the left side rail (32), and the other end part (58) of which is joined to the right side rail (32). Thin-plate parts (63, 64, 65) having a smaller plate thickness than thick-plate parts (62, 62) and thick-plate parts (61, 62) are disposed at the one end (57) and the other end (58) of the front rail (22). The thin-plate parts (63, 64, 65) are each connected to the left and right side rails (32).</p> |
