A hinge mechanism includes a resin base member, and a support rotatably and pivotally mounted to the base member. The base member is formed by blow molding so as to be hollowed. The base member integrally includes a hinge member for rotatably and pivotally mounting the support to the base member. The hinge member is set in a molding die for clamping at the time of the blow molding of the base member, so as to be molded integrally with the base member. |
