1. A vehicle lid seal structure, comprising:
a housing that is provided with a refueling port or an electric power feed port; and
a lid configured to open and close an opening of the housing, wherein:
one of the housing and the lid is provided with an annular sealing member, on a face facing the other;
a cross-sectional structure of the annular sealing member includes a base portion attached to one of the housing and the lid, and a lip portion extending from the base portion toward the other of the housing and the lid;
an end portion of the lip portion on a side opposite to a connecting end of the lip portion and the base portion is a free end; and
the lip portion is provided with a folding starting point between the connecting end and the free end, to cause folding deformation of the lip portion toward a radially-outward side of the annular sealing member,
wherein a substructure portion of the lip portion that extends from the folding starting point to the connecting end is higher in rigidity than a distal end portion that extends from the free end to the folding starting point,
wherein the substructure portion of the lip portion extends from the folding starting point toward the connecting end, being inclined toward the radially-outward side of the annular sealing member, and
wherein:
the annular sealing member is attached to a flange that is annular;
the flange is provided on a peripheral edge portion of the housing and faces the lid;
the substructure portion of the lip portion includes an outer peripheral side face and an inner peripheral side face;
both the outer peripheral side face and the inner peripheral side face are inclined upward from the folding starting point toward the connecting end; and
an upward inclination angle of the inner peripheral side face is smaller than an upward inclination angle of the outer peripheral side face.
