Abstract:
A fuel feed port sealing apparatus comprising:a sealing member made of an elastic material for hermetically sealing the gap between the inner periphery of a fuel feed port and the outer periphery of a fuel feed nozzle inserted thereinto; andan insertion guide for aligning said fuel feed nozzle inserted into said fuel feed port with respect to said sealing member,said sealing member comprising:an outer periphery sealing portion arranged to stick fast to the inner periphery of said fuel feed port; andan inner periphery sealing portion to be moved toward the fuel feed port inner side according to the insertion of said fuel feed nozzle and to be moved toward the fuel feed port opening side according to the removal of said fuel feed nozzle,said inner periphery sealing portion being arranged such that, as moved toward said fuel feed port opening side, said inner periphery sealing portion is increased in inner diameter at its part into which said fuel feed nozzle is inserted, the inner diameter thus increased being greater than the outer diameter of said fuel feed nozzle, and that said part is reduced in inner diameter with the movement of said inner periphery sealing portion toward said fuel feed port inner side, causing said part to stick fast to the outer periphery of said fuel feed nozzle.
