PROBLEM TO BE SOLVED: To provide a heat shielding structure capable of reducing an area irradiated with radiation heat.SOLUTION: In a heat shielding structure for shielding radiation heat from heat sources 2 and 5 by arranging a heat insulator 4 so as to cover the heat sources 2 and 5 supported on a prescribed fixing portion by a stay, the heat insulator 4 has a through hole 6 allowing the stay to pass through in a thickness direction thereof, and a wall 7 rising from the through hole 6 toward a side opposite from the heat sources 2 and 5. A part of the radiation heat from surfaces of the heat sources 2 and 5 is shielded by the wall 7. Therefore, a maximum range irradiated with the radiation heat is reduced compared to the case where the wall 7 is not formed. 【課題】輻射熱が照射される領域を小さくすることのできる遮熱構造を提供する。【解決手段】ステーによって所定の固定部に支持された熱源２，５を覆うようにヒートインシュレータ４を配置して熱源２，５からの輻射熱を遮る遮熱構造において、ヒートインシュレータ４に、その厚み方向にステーを貫通させる貫通孔６と、熱源２，５とは反対側に向けて貫通孔６から立ち上がった壁部７とが形成されている。熱源２，５の表面からの輻射熱の一部は、壁部７によって遮られる。そのため、壁部７が形成されていない場合に比較して、輻射熱が照射される最大範囲が小さくなる。【選択図】図１
