The connecting piece 4 is arranged along the circumferential direction of the rim portion 3. Reference numeral 21 denotes a lid, which closes the opening at the tip of the spoke portion 2 in an airtight manner. The end of the connecting piece 4 is connected to the lid 21 in a state of standing upright. That is, the rim portion 3 is connected to the spoke portions 2, 2,.
