It becomes difficult to fall down toward the part 41. - ⁇ Therefore, the first front wall portion 41 and the second front wall portion 51 are less likely to interfere with each other, so that the shock absorbing function can be exhibited more effectively.
  • the ribs 80 may be triangular in cross-section when viewed from the side, or may be concave on the side facing the center of the housing 30 as shown in FIG. 11A. Also, the rib 80 may be convex on the side facing the center of the housing 30 as shown in FIG. 11B. Moreover, the rib 80 may have a portion projecting toward the center of the housing 30, as shown in FIGS. 11C and 11D.
  • the second front wall portion 51 protrudes further forward than the first front wall portion 41, but the first front wall portion 41 protrudes more forward than the first front wall portion 41. It may protrude forward from the two front wall portions 51 .
  • the inclined surface of the first front wall portion 71 is formed so that the tip becomes narrower from the front to the rear
  • the inclined surface of the second front wall portion 72 is formed so that the tip becomes narrower from the rear to the front. is formed to be thin.
  • the shape of the inclined surface is not limited to the shape described above.
  • the slanted surface of the first front wall portion 71 is formed to taper from the rear to the front
  • the slanted surface of the second front wall portion 72 tapers from the front to the rear. You may form so that it may become thin.
  • only one of the upper end portion of the first front wall portion 71 and the lower end portion of the second front wall portion 72 may be provided with the inclined surface.
  • the arrangement with the lower end of the portion 51 is not limited to the arrangement described above.
  • the lower end of the second front wall portion 51 may be positioned above the upper end of the first front wall portion 41 . In this way, when the upper end of the first front wall portion 41 and the lower end of the second front wall portion 51 are arranged at positions that do not overlap in the vertical direction, the upper end of the first front wall portion 41 and the second front wall portion 51 are arranged. may be less than 3 mm.
  • the members for fastening the first housing 31 and the second housing 32 are not limited to the above-described members.
  • a clip may be used as a member that fastens the first housing 31 and the second housing 32 together.
  • the clip abuts, for example, the lower surface of the horizontally extending end of the first housing 31 and the upper surface of the horizontally extending end of the second housing 32, and clamps both members from above and below.
  • the first housing 31 and the second housing 32 may be locked with claws.
  • the interference avoidance structure is provided on the front side of the virtual image display device 100 was exemplified, but the position where the interference avoidance structure is provided is not limited to the position described above.
  • the interference avoidance structure may be provided on at least one of the right side, the left side, and the rear side of the virtual image display device 100 .
  • the windshield 10 was exemplified as the projection member, but the member that reflects the display light is not limited to the members described above.
  • a combiner or the like may be used as a member that reflects the display light.
