To provide a muffler heat shielding structure which can decrease a peak temperature of a surface of an insulator even if a space around the muffler is small.SOLUTION: A muffler heat shielding structure 1 is mounted on a vehicle 2 and shields heat from a muffler 3. The muffler heat shielding structure 1 includes: an outer insulator 5 and an inner insulator 6 which are disposed at the outer side of the muffler 3 when viewed in a vehicle width direction of the vehicle 2; and an attachment tool 7 which attaches the outer insulator 5 and the inner insulator 6 to the muffler 3. The inner insulator 6 is provided with a heat radiation rib 11 for discharging heat from the muffler 3.SELECTED DRAWING: Figure 1

    【課題】マフラの周りのスペースが狭くても、インシュレータの表面のピーク温度を低下させることができるマフラ遮熱構造を提供する。【解決手段】マフラ遮熱構造1は、車両2に搭載され、マフラ3からの熱を遮蔽する。マフラ遮熱構造1は、マフラ3よりも車両2の車幅方向の外側に配置された外側インシュレータ5及び内側インシュレータ6と、外側インシュレータ5及び内側インシュレータ6をマフラ3に取り付ける取付具7とを備え、内側インシュレータ6には、マフラ3からの熱を放出するための放熱リブ11が設けられている。【選択図】図1
