Abstract: PROBLEM TO BE SOLVED: To ensure the sealing property even when the holding force is set at a degree wherein the attaching/detaching operability may not be spoiled. SOLUTION: This hole closing lid member formed of an elastic material has a base section 10 and a resisting means 11. In this case, the base section 10 is arranged in a manner to be confronted with the opening surface 19 of a hole 18 to be closed, and has the outer edge which is larger than the opening. The resisting means 11 resists a movement in the direction in the axial direction of the hole under a specified lid closed state. In such a hole closing lid member, a lip section 12 is provided to protrude into a ring-shape while corresponding with the total periphery of the opening from the base section to the opening surface, and to expand into a horn shape to the opening surface side. The resisting means protrudes from the base section at a lip internal location, and is a plug body section which is fitted in the hole under a press-fitted state.  The plug body section is formed into a cylindrical shape. Then, the outer peripheral surface of the plug body section has an outer diameter-expanded section 13 of which the outer diameter is larger than the inner diameter of the hole, and outer diameter-reduced sections 14 and 15 of which the outer diameter is smaller than the inner diameter of the hole. In this case, the material of the hole closing lid member is polypropylene.
