Abstract: A front pillar structure includes a first skeleton portion, a second skeleton portion extending along the first skeleton portion with a gap therebetween, and a connecting member. A cross-section of the first skeleton portion is a hollow closed cross-section and a width of the first skeleton portion in a horizontal direction orthogonal to a gaze direction of a driver seated in a driver's seat is equal to or less than a standard pupillary distance. A cross-section of the second skeleton portion is a hollow closed cross-section and a width of the second skeleton portion in the horizontal direction orthogonal to the gaze direction is equal to or less than the standard pupillary distance. The connecting member is transparent and is disposed between the first skeleton portion and the second skeleton portion.

Abstract: A vehicle pillar structure that includes: a first framework section that extends along a first vehicle width direction side edge of a front windshield of a vehicle; a second framework section that is provided so as to form a gap toward a vehicle rear and vehicle width direction outer side of the first framework section, that extends along the first framework section; and a see-through section that is formed so as to be see-through and that spans between the first framework section and the second framework section, wherein the first framework section and the second framework section are each formed with a closed cross-section as viewed along their length directions, and at least one of a rear edge corner of the first framework section or a front edge corner of the second framework section is formed with a beveled profile.

Abstract: A vehicle pillar structure, including: a first pillar; a second pillar that is disposed a predetermined distance away from the first pillar substantially in a vehicle front-rear direction, with an upper end portion of the second pillar being coupled to an upper end portion of the first pillar and with a lower end portion of the second pillar being coupled to a lower end portion of the first pillar; a transparent member that spans between the first pillar and the second pillar to thereby cover an opening formed by the first pillar and the second pillar, and through which an area exterior to the vehicle can be seen; and a reinforcement member that couples a vehicle upper portion side of the first pillar to a vehicle upper portion side of the second pillar substantially in the vehicle front-rear direction.

Abstract: A vehicle pillar structure including: a pillar outer panel that extends with a length direction substantially in a vehicle vertical direction and configures a first part of a vehicle pillar, the vehicle pillar including a first column extending substantially along the vehicle vertical direction and a second column disposed at a predetermined spacing from the first column and extending substantially along the vehicle vertical direction; a pillar inner panel that configures a second part of the vehicle pillar, that extends with a length direction in the substantially vehicle vertical direction so as to face the pillar outer panel; and a weld portion at which an end in a short direction of one of the pillar outer panel or the pillar inner panel is abutted against a flat face provided at the other of the pillar outer panel or the pillar inner panel, and welded to the flat face.

Abstract: A method manufactures a composite member that can exert a sufficient effect of reinforcing a metal part with a fiber-reinforced resin material when the metal part is obtained by bending a tubular member. The method firstly bends a tubular metal member having a plate-like outer wall extending in the longitudinal direction so that compressive stress acts on the outer wall to manufacture the metal part. Next the method prepares a plate-like metal plate. Next the method attaches a fiber-reinforced resin material to a surface of the prepared metal plate, the fiber-reinforced resin material including a fiber substrate containing reinforcement fibers having one orientation direction and impregnated with uncured thermosetting resin, followed by thermally curing of the thermosetting resin to prepare a reinforcement member. Next the method joins the metal plate of the reinforcement member to the surface of the outer wall of the metal part.
