Abstract

To increase an effect of absorbing an impact load from a vehicle front side. A vehicle-body structure includes a left-side suspension support member supporting a front suspension, a center frame disposed higher than and away from a floor panel at a vehicle-width-direction central portion of an occupant space and extending in a vehicle front-rear direction, a left-side front frame connected to a front portion of the center frame and extending to the left-side suspension support member, a right-side front frame connected to the front portion of the center frame and extending to a right-side suspension support member, and a connection member that connects the floor panel and at least one of a rear portion of the left-side front frame, a rear portion of the right-side front frame, and the front portion of the center frame.

Claims (30)

1. A vehicle-body structure provided in an automobile, the vehicle-body structure comprising:
