Abstract: 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.

Abstract: 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.
