To improve visibility of a display image displayed by a HUD device.SOLUTION: In a HUD device (3) installed to a helmet (101), a projection unit (39) for projecting display light to a combiner (73) comprises: a light emitter (57) for emitting display light; a housing (61) having a projection opening (63) for allowing the display light emitted from the light emitter to pass therethrough; and a translucent cover member (65) provided so as to cover the projection opening. The projection unit is incorporated into the jaw part (113) of the helmet body so as to allow the display light projected to the combiner to pass through a light path (119) provided in a mouth cover (115) of the helmet body (105). The cover member is disposed at the inner side of an interior material with respect to the interior material's surface where the end of the light projection side of the light path is open.SELECTED DRAWING: Figure 5

    【課題】HUD装置によって表示される表示像の視認性を良くする【解決手段】ヘルメット(101)に搭載されるHUD装置(3)において、コンバイナ(73)に表示光を投射する投射ユニット(39)は、表示光を出射する光出射器(57)と、光出射器から出射された表示光を通過させる投射開口(63)が形成されたハウジング(61)と、投射開口を覆うように設けられた透光性を有するカバー部材(65)とを備え、コンバイナに投射される表示光をヘルメット本体(105)のマウスカバー(115)に設けられた光路部(119)に通すようにヘルメット本体の顎部(113)に内蔵され、カバー部材は、内装材の表面における光路部の光出射側の端部が開口した面よりも当該内装材の内方に配置されている。【選択図】図5
