A sidebody structure of a motor vehicle includes a pillar reinforcement member provided in a center pillar so that center pillar has a substantially strong structure against a bending moment when a side impact load is applied thereto. A first yieldable portion is provided at the connecting portion of the center pillar and a side rail so that the center pillar is bent inwardly at the first yieldable portion when a side impact load is applied to the center pillar, and a second yieldable portion is provided at the second connecting portion of the center pillar and a side sill so that the side sill is deformed inwardly at the second yieldable portion, being pushed by the incoming center pillar. Thus, in an event of a side collision, a passenger's seat swings inwardly around the connecting portion of the center pillar and the side rail like a pendulum, coordinating with the movement of the center pillar, whereby a passenger can avoid being struck by the incoming center pillar.
