To simplify a bearing structure of an optical element disposed in an image irradiation device such as a HUD device and provide an image irradiation device that enables an optical element to be positioned.SOLUTION: A display (HUD) device 1 installed in a device body 5 includes a concave mirror 3 configured to be inclined about rotation shafts 31, 32, 61. The rotation shafts 31, 61 are rotationally supported by shaft holes of bearings 51, 52 disposed on side walls 53 of the device body 5. The rotation shafts 31, 61 to be rotationally supported are inserted from a different direction from the axial core direction of the shaft holes of the bearings 51, 52 and to be supported thereby. Additionally, a positioning mechanism 7 configured to position the axial direction of the rotation shafts of the concave mirror 3 is disposed on the device body 5.SELECTED DRAWING: Figure 3

    【課題】HUD装置等の画像照射装置に設けられる光学要素の軸受構造を簡易化するとともに、光学要素の位置決めを可能にした画像照射装置を提供する。【解決手段】装置ボディ5に内装され、回転軸31,32,61を支点として傾動される凹面鏡3を備える表示装置(HUD)1であり、回転軸31,61は装置ボディ5の側壁53に設けられた軸受51,52の軸穴に回転可能に軸支される。軸受51,52の軸穴は、軸支される回転軸31,61が軸穴の穴芯方向とは異なる方向から内挿されて軸支される。また、装置ボティ5には凹面鏡3の回転軸の軸方向の位置決めを行う位置決め機構7が設けられる。【選択図】 図3
