Therefore, it is preferable that the cover member such as the cover glass is configured so as not to be easily broken for the purpose of protecting the occupant.
  • the above head impact range may be set based on the regulations of the area where the vehicle is used.
  • the head impact range is the "Technical Standard for Shock Absorption of Instrument Panel” in "Article 20 Boarding Device” of "Safety Standards for Road Transport Vehicles” shown by the Japanese Ministry of Land, Infrastructure, Transport and Tourism. It may be set based on the range shown in the above.
  • Patent Document 1 it is expected that the strength against a shock (in other words, bending fracture) from a direction substantially perpendicular to the main surface of the cover glass can be expected.
  • the display device for a vehicle of Patent Document 1 is configured on the assumption that the head collides with the surface portion of the cover glass in a direction orthogonal to the surface portion.

Therefore, it is preferable that the display device for a vehicle is configured so that the cover glass is not easily broken even when the head collides obliquely from the upper end on the viewing side of the device.

Further, since the upper visible side end portion projects toward the visible side from the surface of the cover member, the upper visible side end portion tends to be displaced downward due to the impact of the head collision. That is, the upper visible side end portion continues to be interposed between the head portion and the edge portion of the cover member. As a result, it is possible to reduce the risk of collision impact on the edge portion of the cover member. Therefore, it is possible to reduce the risk of the cover member cracking due to a head collision with the vehicle display device.
