In a vehicle body side part structure, a front pillar has a pillar inner panel and a pillar outer panel. A side sill has a sill inner panel and a sill outer panel. A sidewall and a front wall of the pillar outer panel on an inner side in a vehicle width direction extend to a position at which the sidewall and the front wall overlap the side sill in an upward/downward direction. A defective section is provided on a front section of the sill outer panel. A reinforcement plate extending in a vehicle upward/downward direction is coupled to a rear region of an inner side surface of the pillar outer panel. A lower end of the reinforcement plate extends to a position at which the lower end overlaps the defective section in the upward/downward direction on a side behind the defective section. A lower edge portion of the sidewall of the pillar outer panel is joined to a sidewall of the sill outer panel on an outer side in the vehicle width direction.

Vehicle body side part structure

A vehicle body front part structure includes a front pillar and an upper member. The upper member includes: a side wall on an outside in a vehicle width direction; and an stiffener that is joined to an inner surface of the side wall, that has a rear end part facing a front surface of the front pillar, and that forms a closed cross-section extending substantially in a vehicle body front-to-rear direction together with the side wall. The side wall of the upper member includes: a pillar fixation part that is arranged in a rearward extension area extending in a vehicle body rearward direction further than the rear end part of the stiffener and that is fixed to a side wall on an outside in the vehicle width direction of the front pillar; and a bead shape part that convexly projects outward in the vehicle width direction and that extends to a vicinity of the pillar fixation part from a frontward position further than the rear end part of the stiffener.

Vehicle body front part structure

A subframe structure includes: a left-right pair of extension members extending in a vehicle front-rear direction and each having a rectangular orthogonal cross section; a rear member connected to rear end portions of the extension members and extending in a vehicle width direction; and connecting parts connecting the rear end portions and the rear member. Each extension member includes: a first weak portion located forwardly of the corresponding connecting part and deformable when a load is applied; and a second weak portion located forwardly of the first weak portion and deformable when a load is applied. The first and second weak portions of each extension member are formed in upper and lower faces thereof, respectively. The orthogonal cross section of each extension member has a height, dimension Hat the first weak portion and a height dimension Hat the second weak portion and His smaller than H

Subframe structure

A vehicle body front structure includes: a front side frame; a lower member placed at an outer side of the front side frame in the vehicle width direction; and a gusset placed between the front side frame and the lower member. The front side frame includes a first bending point which absorbs an impact load by being bent by receiving impact load upon a collision of the vehicle. An inner side of the gusset in the vehicle width direction is joined to the outer side of the front side frame in the vehicle width direction and extends from a front end of the front side frame to a first bending point. A tapered part which is inclined toward the front side frame as extending backward from the front end of the gusset is formed in an outer side of the gusset in the vehicle width direction.

Vehicle body front structure

With a structure for a front portion of a vehicle body, a front side frame has a front side frame main unit of which a cross-sectional shape is generally hat-shaped and of which an opening faces the outer direction where a front wheel is placed, a back plate forming a closed cross-section with the inner face of the front side frame main unit being layered with and joined with a flange facing toward the outer direction, and a tire clearance portion formed in a curved shape to correspond to steering range of the front wheels. A sidewall is formed into a sidewall straight portion in an approximately straight line from the tip of the front side frame to the middle including the tire clearance portion. The flange has a flange straight portion formed to the tire clearance portion, approximately parallel with the sidewall straight portion of the sidewall.
