Abstract: A side door comprises a door panel portion and a reinforcement portion (a lower-side reinforcement portion and others). The door panel portion is provided to cover an opening portion for entrance and configured such that its peripheral part overlaps with an opening-portion-forming vehicle-body frame member (a side sill and others) in a vehicle side view. The reinforcement portion is provided at the peripheral part of the door panel portion such that it overlaps with the 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. The reinforcement portion is provided at a portion of the peripheral part of the door panel portion which includes a part corresponding to the vehicle-width-direction-extending vehicle-body frame member (a first floor cross member and others).

Abstract: A tubular body (1) made of a fiber-reinforced plastic and used as a structural material of a vehicle includes corners (4) extending along an axis of the tubular body (1) on an outer circumferential surface thereof. The tubular body (1) is a tubular laminate that is formed by laminating a fabric layer (12) formed by laminating fabric materials and unidirectional material layers (11, 13). Each fabric material includes a fabric in which reinforcing fibers are woven and a plastic with which the fabric is impregnated. Each unidirectional material layer (11, 13) includes reinforcing fibers oriented in one direction and a plastic with which the reinforcing fibers are impregnated. The reinforcing fibers of each unidirectional material layer (11, 13) are oriented along the axis of the tubular laminate. The unidirectional material layers (11, 13) include an outer unidirectional material layer (13) laminated on an outer circumferential surface of the fabric layer (12), and an inner unidirectional material layer (11) laminated on an inner circumferential surface of the fabric layer.

Abstract: A vehicle roof structure is provided capable of maintaining side collision performance of a vehicle even without a roof reinforcing member. The vehicle roof structure includes an annular frame that is joined to a circumferential edge of a roof panel (which includes an outer panel and an inner panel), and supports the roof panel. The annular frame has a higher rigidity than the roof panel, is arranged in an opening of a roof, and is joined to a pair of roof side rails, a front header, and a rear header.

Abstract: There are provided a center pillar, a roof side rail connected to an upper end portion of the center pillar and having a closed cross section extending in a vehicle longitudinal direction, and a synthetic resin-made reinforcing member provided inside the roof side rail at a position near an upper end portion of the center pillar. The roof side rail comprises a roof rail inner having a protrusion portion and a roof rail outer forming the closed cross section together with the roof rail inner. The reinforcing member is provided to have a gap from the roof rail outer and integrally joined to an outward face, in a vehicle width direction, of the roof rail inner which is roughened by an anchor effect.
Abstract translation: 设置有与中心支柱的上端部连接并具有沿车辆前后方向延伸的封闭截面的中心支柱，车顶侧轨道，以及设置在车顶侧轨道内侧的合成树脂加强构件 位于中柱的上端部附近。 车顶侧轨包括具有突出部分和车顶轨道外部的车顶轨道内部，其与车顶轨道内部一起形成封闭的横截面。 加强构件设置成具有与屋顶轨道外侧的间隙，并且与通过锚固效应粗糙化的车顶轨道内部的车辆宽度方向的外侧一体地接合。

Abstract: In a vehicle side body structure, when a force that deforms a side door inward in a vehicle width direction acts on the side door, a second engagement section enters a clearance in the vehicle width direction of the side door, a first engagement section and the second engagement section respectively engage with a first engaged section and a second engaged section, and an engagement structure bent with the first engagement section serving as a fulcrum, so as to prevent the side door from flipping up.
