To provide a muffler support having a novel structure which can facilitate attachment to a vehicle or the like by improving the insertion workability of each attachment shaft into first and second attachment holes.SOLUTION: In a muffler support 10 which has a first attachment hole 12 and a second attachment hole 14 extending across each other by a projection in a vertical direction, and in which a peripheral wall part 16 of the first attachment hole 12 and a peripheral wall part 18 of the second attachment hole 14 are connected to each other by a pair of elastic arm parts 20, and the elastic arm parts 20 are formed into curved shapes which are bulged to the outside, a pressing operation face 30 in an axial direction of the first attachment hole 12 is constituted by enlarging a thickness dimension of a portion located at the first attachment hole 12 side of the elastic arm part 20 compared with a portion located at the second attachment hole 14 side, and by reducing thickness dimensions of the elastic arm parts 20 toward an end part of the second attachment hole 14 side, and making the elastic arm parts approach each other, a length B2 of the second attachment hole 14 is set smaller than maximum outer width dimensions B1 of the elastic arm parts 20.SELECTED DRAWING: Figure 2
【課題】第一及び第二の取付孔に対する各取付軸の挿通作業性を向上させて車両等への装着を容易となし得る、新規な構造のマフラーサポートを提供する。【解決手段】上下方向の投影で互いに交差して延びる第一取付孔12と第二取付孔14を有していると共に、第一取付孔12の周壁部16と第二取付孔14の周壁部18とが一対の弾性腕部20によって連結されており、各弾性腕部20がそれぞれ外方に膨らんだ湾曲形状とされているマフラーサポート10において、各弾性腕部20における第一取付孔12側に位置する部分が第二取付孔14側に位置する部分に比して厚さ寸法を大きくされることで第一取付孔12の軸方向への押圧操作面30が構成されていると共に、各弾性腕部20が第二取付孔14側の端部に向けて厚さ寸法を小さくされると共に相互に接近せしめられることで第二取付孔14の軸方向長さB2が各弾性腕部20の最大外幅寸法B1よりも小さくされている。【選択図】図2
