To provide an attachment part structure of a cover member which can attach a cover member to an attachment hole easily while inhibiting rattling between the cover member and the attachment hole.SOLUTION: An attachment part structure of a cover member 6 includes: a plate member which has an attachment hole 9; and a cover member 6 which has a peripheral wall 11 and is fixed to the attachment hole 9 at the peripheral wall 11. The attachment hole 9 has a burring part 10 at a peripheral edge part. An outer peripheral surface of the peripheral wall 11 is provided with: a first engagement area which contacts with the burring part 10; and a second engagement area which contacts with the burring part 10 at a position facing the first engagement area on a circumference of the peripheral wall 11. The first engagement area is provided with: a removal restriction part which contacts with an extending end 10e of the burring part 10; and an insertion restriction part with which a curved outer surface 10c of the burring part 10 contacts. The second engagement area is provided with digging restriction parts in each of which the burring part digs to restrict displacement of the peripheral wall 11.SELECTED DRAWING: Figure 7
【課題】カバー部材と取付孔の間のがたつきを抑制し、かつカバー部材を取付孔に容易に装着することができるカバー部材の取付部構造を提供する。【解決手段】カバー部材6の取付部構造は、取付孔9を有するプレート部材と、周壁11を有し当該周壁11が取付孔9に固定されるカバー部材6とを備えている。取付孔9は、周縁部にバーリング加工部10を有する。周壁11の外周面には、バーリング加工部10に当接する第1の係止領域と、周壁11の周上の第1の係止領域に向かい合う位置でバーリング加工部10に当接する第2の係止領域が設けられている。第1の係止領域には、バーリング加工部10の延出端10eに当接する抜け規制部と、バーリング加工部10の湾曲外面10cが当接する挿入規制部とが設けられている。第2の係止領域にはバーリング加工部が食い込むことで周壁11の変位を規制される食い込み規制部が設けられている。【選択図】図7
