To improve rigidity of a lower end portion of a center pillar and prevent intrusion at the time of a side collision.SOLUTION: A vehicle side part structure is structured such that a reinforcement member 4 adapted to connect a roof side rail portion 2 and a side sill portion 3 is arranged inward of an outer panel of a center pillar 1. The reinforcement member includes: an outer upper reinforcement member 41 having an upper end portion 11a fixed to the side rail 2; and an outer lower reinforcement member 42 having a lower end portion 42b fixed to the side sill portion 3. An inner lower member 12 having a lower end portion 12b connected to the side sill portion 3 is disposed inward of a lower end portion of the pillar 1. A lower end portion 41b of the upper reinforcement member 41 extends to an upper end portion 12a of the inner lower member 12 to include a connection portion with the inner lower member. Front-to-rear end portions of the lower reinforcement member 42 are connected between the upper reinforcement member 41 and the inner lower member 12. An upper end portion 42a of the lower reinforcement member 42 extends above the upper end portion 12a of the inner lower member 12 to be connected to the lower end portion 41b of the upper reinforcement member 41, and an overlap portion D is formed at the connected portion.SELECTED DRAWING: Figure 2

    【課題】センタピラーの下端部剛性を向上させ、側突時の入り込みを抑制する。【解決手段】センタピラー1のアウタパネルの内側にルーフサイドレール部2とサイドシル部3との間を接合する補強部材4が配置された車両側部構造において、補強部材は、上端部11aがサイドレール部2に固定される外側上部補強部材41と下端部42bがサイドシル部3に固定される外側下部補強部材42を有し、該ピラー1の下端部内側には下端部12bがサイドシル部3に接合される内側下部部材12が設けられ、上部補強部材41の下端部41bは、内側下部部材12の上端部12aまで延び、内側下部部材との接合部を有し、下部補強部材42の前後端部は上部補強部材41と内側下部部材12との間に接合され、下部補強部材42の上端部42aは、内側下部部材12の上端部12aよりも上方へ延び、上部補強部材41の下端部41bに接合され、接合部箇所には重複部Dが形成される。【選択図】図2
