In addition, it is not necessary to open and close the lid with force, and the lid opens and closes within the opening and closing stroke of the lid due to the urging force of the elastic member. For this reason, the force acting on the hinge is within the fatigue limit, and the hinge is less likely to break. Also, when the lid is opened and closed, the elastic member slides on the rib, so that the lid does not shake. Further, since the elastic member does not connect the lid and the main body, the mold can be released and released at the same time. Further, since the labor for connecting the elastic member to the main body as in the related art can be omitted, the manufacturing cost is reduced.
