Therefore, in the event of a vehicle collision or the like, an occupant collides with the upper surface of the instrument panel, and a large load is input to the instrument panel, causing the bolt to move relatively from the bolt insertion hole toward the upper plate portion through the slit. When the instrument panel and the instrument panel supporting member are moved upward from the opening of the upper plate portion, the instrument panel and the instrument panel support member can be dropped downward from the vehicle body side support surface portion on the vehicle body side. can be done. Therefore, it is possible to reduce the impact from the instrument panel to the occupant side, so that the occupant protection performance can be improved.

A third aspect of the present invention is the instrument panel mounting structure according to the first aspect or the second aspect, wherein the width of the slit is narrower than the diameter of the bolt insertion hole.

In the above configuration, the width of the slit is formed to be narrower than the diameter of the bolt insertion hole of the fixed plate portion, so that when the bolt relatively moves upward in the slit, the bolt contacts the edge of the slit. easy. Therefore, when the bolt relatively moves upward in the slit, the impact of the occupant can be absorbed by the contact between the bolt and the edge of the slit.

In addition, since the width of the slit is narrower than the diameter of the bolt insertion hole, setting the width of the slit appropriately (for example, setting it narrower than the diameter of the shaft of the bolt) allows the input of a small load. Sometimes, it is possible to prevent the instrument panel from easily moving downward.

According to the present disclosure, it is possible to improve the occupant protection performance when the occupant collides with the upper surface of the instrument panel.
