Abstract: A surrounding structure of a door holding mechanism includes: an outer panel forming a pillar with an inner panel; a sliding door rearward of the pillar; a door holding mechanism holding the sliding door in a closed condition; and a pillar forming area of the outer panel having a substantially crank-shaped cross-section, wherein the door holding mechanism is attached to a front face of an intermediate portion of the pillar forming area, a pillar reinforcement is arranged between the outer and inner panel and includes front and rear portions, the front portion is overlapped with a rear face of the intermediate portion of the pillar forming area, the rear portion extending rearward from the front portion and having a substantially crank-shaped form in a longitudinal direction thereof, the pillar forming area and pillar reinforcement form a closed section, the pillar reinforcement joined to the outer panel.

Abstract: The present invention provides a pillar structure for a vehicle body rear portion which can suppress deformation of a pillar when a load is applied outward to a slide door in a state in which said slide door is closed. The slide door opens and closes an opening provided in a vehicle side surface. A pillar portion is composed of a closed section of an inner and outer panel. A fixing mechanism fixes a rear portion of said slide door at a closed position. Said fixing mechanism is provided on a surface facing a vehicle body front side of said pillar portion. A pillar reinforcement body forming a quadrangular closed section is mounted to an inner surface of said pillar portion. An interior-side reinforcement member is disposed between said pillar reinforcement body and said inner panel so as to have a gap in a vehicle width direction.
