PROBLEM TO BE SOLVED: To simplify and reduce the weight of a double hinged structure of a lid member, and to materialize the smooth opening/closing operation of the lid member. SOLUTION: To a first mounting plate portion 17 positioned on a rear side of an upper opening portion 12, a first lid supporting member 60 is rotatably supported by a first hinge portion 55. To a second mounting plate portion 18 positioned on a front side of the upper opening portion 12, a second lid supporting member 80 is rotatably supported by a second hinge portion 56. A moving member 100 arranged in a lid member L reciprocates between a first coupling position on the first hinge portion 55 side and a second coupling position on the second hinge portion 56 side. The moving member 100 moving to the first coupling position is coupled to the first lid supporting member 60, and the lid member L opens/closes while supported by the first lid supporting member 60. The moving member 100 moving to the second coupling position is coupled to the second supporting member 80, and the lid member L opens/closes while supported by the second lid supporting member 80.
