Abstract

A vehicle side portion structure including: a rocker that extends in a vehicle longitudinal direction at a vehicle transverse direction outer side of a vehicle body lower portion; a sliding door that slides in the vehicle longitudinal direction, includes a door inner panel, which is connected to the rocker by a door hinge slidable in the vehicle longitudinal direction and which has a mounted-to portion that is lined up in a vehicle transverse direction with the rocker, and includes a door outer panel that is disposed further toward a vehicle transverse direction outer side than the door inner panel; and a load transmitting member that is mounted to the mounted-to portion and transmits a collision load, which is input to the door outer panel from a vehicle side, to a region of the rocker that is different from a region to which the door hinge is connected.

First claim

What is claimed is:

1. A vehicle side portion structure comprising:
a rocker that extends in a vehicle longitudinal direction at a vehicle transverse direction outer side of a vehicle body lower portion;
a sliding door that slides in the vehicle longitudinal direction, includes a door inner panel, which is connected to the rocker by a door hinge slidable in the vehicle longitudinal direction and which has a mounted-to portion that is lined up in a vehicle transverse direction with the rocker, and includes a door outer panel that is disposed further toward a vehicle transverse direction outer side than the door inner panel; and
a load transmitting member that is mounted to the mounted-to portion and transmits a collision load, which is input to the door outer panel from a vehicle side, to a region of the rocker that is different from a region to which the door hinge is connected.

2. The vehicle side portion structure of claim 1 , wherein:
the door hinge includes a mounted portion that is disposed between the rocker and the door inner panel, and that is superposed from a vehicle transverse direction inner side on the mounted-to portion, and that is mounted to the mounted-to portion by fasteners; and
the load transmitting member is mounted, together with the mounted portion, to the mounted-to portion by the fasteners.

3. The vehicle side portion structure of claim 1 , wherein:
a side member outer panel that structures an outer plate of a vehicle is provided at a vehicle transverse direction outer side of the rocker; and
the load transmitting member includes:
a facing portion that faces the side member outer panel in the vehicle transverse direction, and
a protruding portion that protrudes from the facing portion toward a vehicle transverse direction inner side and is lined up in a vehicle vertical direction with the rocker and the side member outer panel.

4. The vehicle side portion structure of claim 3 , wherein:
an accommodating portion, which is recessed toward a vehicle transverse direction inner side and accommodates the door hinge, is provided at the rocker; and
the protruding portion includes a first protruding portion that protrudes toward an inner side of the accommodating portion, and a second protruding portion that protrudes toward at least one of an upper side and a lower side, in the vehicle vertical direction, of the rocker.

5. The vehicle side portion structure of claim 1 , wherein:
a lower portion, in a vehicle vertical direction, of a center pillar that is provided so as to extend in the vehicle vertical direction is fixed to the rocker; and
the load transmitting member is disposed between the door inner panel and the door outer panel so as to span between the rocker and the center pillar when projected in the vehicle transverse direction, and is mounted to the mounted-to portion from a vehicle transverse direction outer side.

6. The vehicle side portion structure of claim 1 , wherein the load transmitting member is disposed between the door inner panel and the door outer panel, and is mounted to the mounted-to portion from the vehicle transverse direction outer side.

7. The vehicle side portion structure of claim 6 , wherein the load transmitting member is formed in a hat shape in cross-section that opens toward the vehicle transverse direction inner side.
