Abstract: A back door structure of a vehicle capable of reducing noise in a vehicle interior by suppressing vibration of an outer panel while reducing the weight and costs includes an outer panel and an inner panel. The inner panel includes a horizontal frame part, side-direction frame parts, and connecting parts. The horizontal frame part and each of the side-direction frame parts are mutually connected. The connecting part extends only from one end part on an opening part side in a vertical width direction of the horizontal frame part, the connecting part extends only from one end part on an opening part side in the vertical width direction of the side-direction frame part, and the connecting part extends only from one end part on an opening part side in the vertical width direction of the side-direction frame part. The connecting parts are respectively connected to the outer panel.

Abstract: A back door that reduces noise in a vehicle interior by suppressing vibration of an outer panel while reducing the weight and costs includes an outer panel and an inner panel. The inner panel includes a horizontal frame part, vertical frame parts, merging parts, and connecting parts. The connecting part extends only from one end part on an opening part side in a width direction of the horizontal frame part, the connecting part extends only from one end part on an opening part side in the width direction of the vertical frame part, and the connecting part extends only from one end part on an opening part side in the width direction of the vertical frame part. The connecting parts are respectively connected to the outer panel. The merging parts are formed with higher torsional rigidity than the horizontal frame part and the vertical frame parts.

Abstract: A body front structure for an automobile includes: fenders; an engine compartment; a bonnet; a cowl grille; a center seal which is installed on an upper portion of a vertical wall section of the cowl grille; and side seals which are made from a material that is more flexible than the vertical wall section of the cowl grille. A void where the vertical wall section is not present is formed between each fender and an outside end portion of the vertical wall section of the cowl grille in the vehicle width direction. The side seals each have a seal section which abuts against the bonnet in a closed state and a supporting section which supports the seal section from below, and extend substantially in the vehicle width direction so as to close off the void.
