Abstract: A side collision load transmission structure including a floor tunnel, a vehicle compartment side wall, a vehicle seat, side frames, a first transmission member that couples together lower end portions of the pair of side frames along the vehicle width direction, a load receiving member, and a second transmission member that couples together a portion further to a seatback up-down direction upper side than a join portion with the first transmission member on the side frame, out of the pair of side frames, on the vehicle compartment side wall side and a portion of the first transmission member that is further to a vehicle width direction outside than the length direction center of the first transmission member so as to be coupled at an incline as viewed from the front of the vehicle.

Abstract: A vehicle side door structure is provided including: an outer panel that configures a portion at a vehicle width direction outer side of a side door and that extends along a vehicle up-down direction and a vehicle front-rear direction; an inner panel that configures a portion at a vehicle width direction inner side of the side door, that extends along the vehicle up-down direction and the vehicle front-rear direction, and that, together with the outer panel, forms an internal space; an impact beam having both length direction end portions fixed to the inner panel, that is configured in a straight tube shape extending along the vehicle front-rear direction, and that is disposed at an outer panel side in the internal space; and a sensing bracket that is provided at the impact beam and that juts out from the impact beam toward the outer panel.

Abstract: Provided is a vehicle-body lower structure with a side collision sensor which vehicle-body lower structure can attain early sensing by improving a body structure. A first load transmission member of which a longitudinal section has a generally Z-shape is disposed in a closed section of a rocker. A first joining portion of first load transmission member is joined in a state where first joining portion is sandwiched between an upper flange of a rocker outer panel and an upper flange of a rocker inner panel, and a second joining portion is joined to an intermediate part, in a height direction, of a vertical wall portion of rocker outer panel. A body portion connects first joining portion and second joining portion diagonally, and transmits a load input into rocker outer panel at time of a side collision, to an upper-wall-portion side of rocker inner panel by a shortest distance.
