To increase an effect of absorbing an impact load from a vehicle front side. A vehicle-body structure includes a left-side suspension support member supporting a front suspension, a center frame disposed higher than and away from a floor panel at a vehicle-width-direction central portion of an occupant space and extending in a vehicle front-rear direction, a left-side front frame connected to a front portion of the center frame and extending to the left-side suspension support member, a right-side front frame connected to the front portion of the center frame and extending to a right-side suspension support member, and a connection member that connects the floor panel and at least one of a rear portion of the left-side front frame, a rear portion of the right-side front frame, and the front portion of the center frame.

To decrease the retraction amount of a traveling motor at front collision. A vehicle-body structure includes a floor panel constituting a floor of an occupant space including a seat on which a passenger sits, a center frame disposed to be higher than and away from the floor panel at a vehicle-width-direction central portion of the occupant space and extending in a vehicle front-rear direction, and a connecting member extending upward from the floor panel, having an upper portion fixed to the center frame, and connecting the center frame to the floor panel. A traveling motor is arranged on a vehicle front side of the connecting member.

Each rear pillar () includes a rear pillar inner panel () and a rear pillar reinforcement (). The rear pillar inner panel () and the rear pillar reinforcement () each include a substantially L-shaped corner portion (C, C) raised toward the rear pillar inner panel (), and a ridge portion (X, X). The corner portions (C, C) are arranged next to each other in the direction toward a reinforcement (), and an L-shaped closed cross section () is formed between the corner portions (C, C). The reinforcement () is, not via the closed cross section, directly connected to the corner portions (C, C). An upper portion of the L-shaped closed cross section () is connected to a closed rear header cross section ().

The purpose of the present invention is to obtain a method for forming an excellent multi-layer coating film of high chroma and brightness and a rich color. With the method, color mottling does not occur easily in the coating film and the design obtained is homogeneous even without strict control of variations in film thickness during coating. The method for forming the excellent multi-layer coating film comprises: forming a metallic base coating film on the surface of the object to be coated by applying a metallic base coating containing a shiny material; then forming a color base coating film by applying a color base coating; subsequently forming a clear coating film by applying a clear coating on the color base coating film; and heat-curing the metallic base coating film, the color base coating film and the clear coating film obtained. In the method, the light reflectance of the metallic base coating film is in a specified range and the light transmittance of the single color base coating film obtained by heat-curing the color base coating film as a single film is adjusted to a specified range.

Method for forming excellent multi-layer coating film

A rear pillar inner provided at a side panel inner and extending upward from a front-side upper portion of a rear wheel house, a rear pillar reinforcement joined to an outside portion of the rear pillar inner, and an outside reinforcing member connecting an outside portion of the side panel inner and the rear wheel house are provided. The rear pillar reinforcement has a rear-side pillar-reinforcement ridge portion extending vertically. The outside reinforcing member has a front-side reinforcing-member ridge portion extending vertically. A lower end portion of the rear pillar reinforcement and an upper end portion of the outside reinforcing member are joined such that the both ridge portions are arranged to align substantially straightly, when viewed from the side, and to slant in such a manner that an upper side thereof is positioned relatively forward compared to a lower side thereof.

Rear vehicle-body structure of vehicle

A pair of right-and-left center pillars, a pair of right-and-left roof side rails, and an inflator provided on the inside, in a vehicle width direction, of the roof side rails and capable of supplying a gas pressure to an airbag are provided. A roof reinforcing member which extends in the vehicle width direction over respective upper end portions of the center pillars or respective nearby portions to upper ends of the center pillars is provided, which includes a front concave portion and a rear concave portion which are concaved downward respectively. The inflator is arranged such that at least a portion of the inflator overlaps with the roof reinforcing member, and a depth of the rear concave portion overlapping with the inflator is shallower than that of the front concave portion positioned nearer the center pillars.

Upper vehicle-body structure of vehicle

A bridge-shaped frame member is disposed on a front side frame in front of a suspension tower so as to extend vertically and stride over a No. 4 mount. Accordingly, there can be provided a vehicle front body structure that can attain a proper energy absorption of the front side frame with its axial compression can be attained at a vehicle crash.
