Abstract:
An attachment structure for a hole plug is provided with: a first member to be attached in which a first attachment hole is formed; a second member to be attached in which a second attachment hole larger in diameter than the first attachment hole is formed and over which the first member to be attached is superposed; a cylindrical outer peripheral wall part inserted through the first attachment hole and the second attachment hole; and a hole plug having a blocking part that closes the interior of the outer peripheral wall part, an annular flange part that extends outward in the radial direction of the outer peripheral wall part from an end on the side opposite in the insertion direction of the outer peripheral wall part and that covers a part around the second attachment hole, and a hook part that protrudes radially outward from a side at the end along the insertion direction of the outer peripheral wall part and engages with an edge part of the first attachment hole. When a reverse surface of the flange part is in contact with both the edge part of the first attachment hole and an edge part of the second attachment hole, the portion of the flange part in contact with the edge part of the second attachment hole is thicker than the portion in contact with the edge part of the first attachment hole.
