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. ## Claims ### Claim 1 A pillar structure for a vehicle body rear portion in which a slide door that opens and closes an opening portion provided in a vehicle side surface is provided, a pillar portion on a vehicle body rear portion side of the opening portion is composed of a closed section of an inner panel and an outer panel, and a fixing mechanism that fixes a rear portion of said slide door at a closed position of said slide door is provided at said pillar portion on the vehicle body rear portion side, wherein said fixing mechanism is provided on a surface facing a vehicle body front side of said pillar portion on the vehicle body rear portion side, a pillar reinforcement body that forms a quadrangular closed section in horizontal section is internally mounted to an inner surface of said pillar portion on the vehicle body rear portion side to which said fixing mechanism is mounted, and 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 between the interior-side reinforcement member and said pillar reinforcement body. ### Claim 2 (depends on 1) The pillar structure for a vehicle body rear portion according to claim 1, wherein said pillar reinforcement body is formed by combining a vehicle body inner-side reinforcement member and a vehicle body outer-side reinforcement member whose horizontal sections are respectively formed in substantially L shapes; a front surface wall portion of said pillar portion on the vehicle body rear portion side is formed by said outer panel; a front surface portion of the vehicle body outer-side reinforcement member is overlapped on an inner wall surface of the front surface wall portion of said pillar portion on the vehicle body rear portion side; a rear surface portion of the vehicle body outer-side reinforcement member is extended to a vehicle body rear side; and the vehicle body inner-side reinforcement member that forms said quadrangular closed section together with said vehicle body outer-side reinforcement member is joined to a front end portion and a rear end portion of said vehicle body outer-side reinforcement member. ### Claim 3 (depends on 2) The pillar structure for a vehicle body rear portion according to claim 2, wherein a corner portion on a vehicle body rear outer side of said quadrangular closed section formed by said vehicle body outer-side reinforcement member and said vehicle body inner-side reinforcement member is formed as a substantially right angle in horizontal section. ### Claim 4 (depends on 3) The pillar structure for a vehicle body rear portion according to claim 3, wherein a reinforcement member is disposed in a vehicle body longitudinal direction at a bottom of a window portion of said slide door, and said fixing mechanism, said vehicle body outer-side reinforcement member, said vehicle body inner-side reinforcement member, and said interior-side reinforcement member are overlapped in vehicle body front view at a height of a lower end position of the reinforcement member. ### Claim 5 (depends on 1) The pillar structure for a vehicle body rear portion according to claim 1, wherein a corner portion on a vehicle body rear outer side of said quadrangular closed section formed by said vehicle body outer-side reinforcement member and said vehicle body inner-side reinforcement member is formed as a substantially right angle in horizontal section. ### Claim 6 (depends on 5) The pillar structure for a vehicle body rear portion according to claim 5, wherein a reinforcement member is disposed in a vehicle body longitudinal direction at a bottom of a window portion of said slide door, and said fixing mechanism, said vehicle body outer-side reinforcement member, said vehicle body inner-side reinforcement member, and said interior-side reinforcement member are overlapped in vehicle body front view at a height of a lower end position of the reinforcement member. ### Claim 7 (depends on 1) The pillar structure for a vehicle body rear portion according to claim 1, wherein a reinforcement member is disposed in a vehicle body longitudinal direction at a bottom of a window portion of said slide door, and said fixing mechanism, said vehicle body outer-side reinforcement member, said vehicle body inner-side reinforcement member, and said interior-side reinforcement member are overlapped in vehicle body front view at a height of a lower end position of the reinforcement member.
