Rear vehicle body structure

A vehicle body includes: a vehicle body floor having a battery housing portion; a pair of left and right side sills; a front cross member disposed in front of the battery housing portion; a rear cross member disposed behind the battery housing portion; and a battery cover that covers a battery from above. A widened portion of which a height in a vertical direction increases with respect to a center region of the front cross member in a vehicle width direction and of which a front-rear width expands to a vehicle rear side with respect to a front-rear width of the center region of the front cross member in the vehicle width direction is provided on an end portion of the front cross member on an outer side in the vehicle width direction. The battery cover is made of a metal and includes an outer connecting portion connected to the widened portion on an outer side in the vehicle width direction.

Vehicle body lower section structure

A rear portion of a vehicle body includes a front floor panel, a rear floor panel, a pair of left and right side sills, and a front cross plate. The rear floor panel has a higher upper surface height than the front floor panel. The front cross plate connects a rear portion of the front floor panel and a front wall of the rear floor panel, and an outer end portion in a vehicle width direction is coupled to the left and right side sills. The front wall of the rear floor panel has a plurality of bent corner portions having a side view shape bent in a substantially L shape. At least one of the bent corner portions constitutes a closed cross section extending along the vehicle width direction together with the front cross plate in a vertical height range of the left and right side sills.

A catcher structure of a door beam is provided. A catcher mechanism is composed of an engaging hook connected to a rear end part of a door beam, and an insertion hole provided at a lower end part of a center pillar, which is a member on a vehicle body side. In a state in which a door is closed, the rear end part of the door beam, and the engaging hook and the insertion hole of the catcher mechanism are arranged at positions overlapping with each other when viewed from a vehicle width direction. The engaging hook includes a projection part projecting from the rear end part of the door beam toward an inner side in the vehicle width direction, and the insertion hole opens toward an outer side in the vehicle width direction.
