Vehicle-body structure of vehicle

A vehicle-body structure of a vehicle, comprising:

• an opening-portion-forming vehicle-body frame member forming an opening portion for entrance at a vehicle side part;
• a side door provided so as to open and close the opening portion;
• and
• a vehicle-width-direction-extending vehicle-body frame member extending in a vehicle width direction from a portion, in a peripheral direction of the opening portion, of said opening-portion-forming vehicle-body frame member,
• wherein said side door comprises a door panel portion and a reinforcement portion, the door panel portion being provided to cover said opening portion and configured such that a peripheral part thereof overlaps with said opening-portion-forming vehicle-body frame member in a vehicle side view, the reinforcement portion being provided at the peripheral part of said door panel portion such that the reinforcement portion overlaps with said opening-portion-forming vehicle-body frame member in the vehicle side view, thereby reinforcing the peripheral part of the door panel portion against a collision load applied to the side door from a vehicle side,
• wherein said reinforcement portion is provided at a portion of the peripheral part of the door panel portion which includes a part corresponding to said vehicle-width-direction-extending vehicle-body frame member;
• wherein the vehicle-body structure of the vehicle further comprises:
• a front-side reinforcement portion, disposed along an inner front portion of the door panel portion which extends in a substantially vertical direction along a hinge pillar of the opening-portion-forming vehicle-body frame member,
• a rear-side reinforcement portion, disposed along an inner rear portion of the door panel portion which extends in a substantially vertical direction along a lower part of a center pillar of the opening-portion-forming vehicle-body frame member,
• a lower-side reinforcement portion, disposed along an inner lower portion of the door panel portion which extends along a side sill of the opening-portion-forming vehicle-body frame member and connects a lower-side end portion of the inner front portion and a lower-side end portion of the inner rear portion, and
• an upper-side reinforcement portion, disposed at a window frame portion of the door panel portion which forms a window opening portion and extends along a roof-side outer panel of the opening-portion-forming vehicle-body frame member;
• wherein the front-side reinforcement portion overlaps with a rear-side hinge-pillar flange and a hinge-pillar side wall portion of the hinge pillar in the vehicle side view,
• wherein the rear-side reinforcement portion overlaps with a front-side center-pillar flange and a center-pillar-side wall portion of the center pillar in the vehicle side view,
• wherein the lower-side reinforcement portion overlaps with an upper-side side-sill flange and a side-sill side wall portion of the side sill in the vehicle side view, and
• wherein the upper-side reinforcement portion overlaps with a roof-side flange of the roof-side outer panel in the vehicle side view.
