Abstract: A vehicle door attached to a vehicle body includes a bracket structure disposed between an interior-side panel and an exterior-side panel to support a door lock portion. The bracket structure has an interior-side extension portion disposed on an interior-side and joined to the interior-side panel, and an exterior-side extension portion disposed on an exterior-side and joined to the exterior-side panel. Extension portions extend in an upper-lower direction. As an alternative, a vehicle door includes a middle panel disposed between an inner panel and an outer panel, and a bracket structure disposed between the inner panel and the middle panel to support the door lock portion. The bracket structure has a front extension portion disposed frontward and joined to the inner panel, and a rear extension portion disposed rearward and joined to the middle panel. Extension portions are disposed in a front-rear direction of a vehicle and extend upward.

Abstract: An opening-closing member including an outer panel that faces an outside of a vehicle body, and opening and closing a rear opening of the vehicle body in response to operation of an operation part arranged at a rear end part, the opening-closing member including a bracket member in the operation part, the bracket member including a bracket member body extending along a vehicle body front-rear direction, and a vertical wall extending in a vehicle body vertical direction from at least one end part of the bracket member body in the vehicle body front-rear direction, the vertical wall being fixed to an inner side of the outer panel.

Abstract: An opening and closing member is attachable, in an openable and closable manner, to a rear opening of a vehicle body via a pair of hinges. The opening and closing member includes an outer panel and a reinforcing member. The outer panel and the reinforcing member form a window frame. The reinforcing member has closed section parts formed by an outer reinforcing member and an inner reinforcing member. The closed section parts have a pair of front-rear closed section parts that extend in a vehicle body front-rear direction, and a pair of inclined closed section parts that respectively extend from ends, located adjacent to a vehicle body front side, of the pair of front-rear closed section parts, and that respectively incline inwardly in the vehicle body width direction. Open section parts are respectively provided between the hinges and the front-rear closed section parts.
