To provide a cover member which can suppress reflection while avoiding complication of a structure.SOLUTION: A bezel 70 is used in a movable body such as a vehicle mounted with a HUD device. The HUD device is the virtual image display device which displays a virtual image with projection of display light. The bezel 70 is a cover member which is installed so as to cover at least a portion of a housing 51 in the periphery of a projection opening formed in the housing 51 of the HUD device and includes a wall surface structure 70b. The wall surface structure 70b is formed within an expected reach range 70a where reflection outer light ROL incident on the inside of the housing 51 through the projection opening and reflected on a second reflection surface 32 in the housing 51 is assumed to arrive. The wall surface structure 70b includes a plurality of first wall surfaces 71 facing the first direction D1 and a plurality of second wall surfaces 72 facing the second direction D2 and has such a constitution that the first wall surfaces 71 and the second wall surfaces 72 are alternately arranged one by one.SELECTED DRAWING: Figure 7

    【課題】構造の複雑化を回避しつつ、映り込みの抑制が可能なカバー部材を提供する。【解決手段】ベゼル70は、HUD装置を搭載する車両等の移動体において用いられる。HUD装置は、表示光の投影によって虚像を表示する虚像表示装置である。ベゼル70は、HUD装置の筐体51に形成される投影開口の周囲に、当該筐体51の少なくとも一部を覆うように設置されるカバー部材であり、壁面構造70bを備えている。壁面構造70bは、投影開口を通じて筐体51の内部に入射し、筐体51の内部の第2反射面32にて反射された反射外光ROLの到達が想定される到達想定範囲70aに形成される。壁面構造70bは、第1方向D1を向く複数の第1壁面71及び第2方向D2を向く複数の第2壁面72を含み、第1壁面71及び第2壁面72が交互に1つずつ並ぶ構成とされる。【選択図】図7
