Abstract: A lower structure of a vehicle includes front side frames, a vehicle body strength member, a floor panel, and a power supply unit, in which the front side frames are formed to have cross-sectional shapes that open upward at least at rear sections thereof, the power supply unit is disposed below a floor panel, the floor panel includes a pair of reinforcing panel portions which are respectively joined to the rear sections of the front side frames and cover the rear sections from above, and a floor panel main body portion which constitutes a portion other than the reinforcing panel portions, and the reinforcing panel portions are formed to have higher strength than the floor panel main body portion.

Abstract: In a vehicle body front structure including a dashboard panel (10), a damper housing (18) attached to a front side of the dashboard panel, and a component mounting part reinforcing plate (24) attached to the dashboard panel, a dashboard panel reinforcing plate (40, 48, 50) extends between the attachment part of the dashboard panel for the vehicle body structure member and the attachment part of the dashboard panel for the component mounting part reinforcing plate, and is attached to the dashboard panel. The dashboard panel reinforcing plate is adjacent to or overlaps with the attachment part of the dashboard panel for the vehicle body structure member of the dashboard panel without being attached to the vehicle body structure member, and has a part (40B) attached to or adjacent to the component mounting part reinforcing plate.
