An intermediate plate member (22) having a thickness less than or equal to that of a plate of a door body (19) is provided between the door body (19) and a reinforcing member (24) which constitute a right side door (18). The door body (19) and the intermediate plate member (22) are joined together by spot welding, and the intermediate plate member (22) and the reinforcing member (24) are joined together by fillet welding. By this, the reinforcing member (24) is joined to an inner surface (19A) of the door body (19) through the intermediate plate member (22). In this process, when the door body (19) and the intermediate plate member (22) are joined together by welding, the intermediate plate member (22) having lower strength than the door body (19) deforms before the door body (19) deforms, and this minimizes the possibility of occurrence of strain in the door body (19) to maintain the aesthetic appearance of the right side door (18) in a good condition.
