A paint baking method includes a process for conveying a vehicle body (B) while exposing the vehicle body to a hot air atmosphere to bake a wet coating film applied to the vehicle body. In the vehicle body, hinges (HI, H2) and door offset members (70) are attached between hinge fastening parts (BT11, BT21) of the main shell body (B1) and hinge fastening parts (BT12, BT22) of the side doors. The distance (L1) between the hinge fastening parts of the main shell body and the hinge fastening parts of the side door in a state in which the hinges and the door offset members are attached is longer than a distance between the hinge fastening parts of the main shell body and the hinge fastening parts of the side door in a finished vehicle state.
