Abstract: There is obtained a cooling structure for a vehicle that can keep low a temperature of an interior of a power unit chamber in which a power unit is disposed. A cooling structure for a vehicle has: a power unit that is disposed within a power unit chamber disposed at a vehicle front side and at which air intake ports are formed in a front end side in a vehicle front-rear direction; an air-cooling-type heat exchanger that is disposed at a rear side with respect to the power unit, and that is cooled by heat exchange with air that passes from a front side to a rear side; and a communication duct that communicates a rear side portion with respect to the air-cooling-type heat exchanger and a rear side portion of the power unit in the power unit chamber.

Abstract: A vehicle frame structure includes a tunnel portion provided in a floor and left and right side members. Each of the side members includes a front side member, an inner member, and an outer member. The inner and outer members branch off from the front side member in a direction toward the rear of the vehicle. The inner member extends toward the rear of the vehicle along the tunnel portion. The inner members of the left and right side members are connected together by a plurality of connecting portions in the longitudinal direction of the vehicle at least at a location corresponding to a front portion side of the tunnel portion. These connecting portions break when a front impact load is input to at least one of the side members.

Abstract: There is obtained a cooling wind introduction structure that can suppress entry of foreign matter into a vehicle body from an air intake port. A cooling wind introduction structure has: a duct that guides air, that is taken-in into a vehicle body from an introduction port that opens toward a road surface between a pair of front wheels that are lined-up in a vehicle transverse direction, to a cooling unit as cooling wind; and plural or a single flap that is provided along a vehicle longitudinal direction and a vehicle vertical direction in a vicinity of the introduction port within the duct.

Abstract: An air introduction structure has a lower cover that covers a front portion of a vehicle body from below. The lower cover includes a venturi wall, and a duct portion that diverts air from an inlet opening to a cooling unit that is disposed in the rear of a power unit. The venturi wall is inclined so that a portion thereof near the inlet opening is closer to the road surface than a front end portion of the venturi wall.

Abstract: A cooling airflow intake structure that can efficiently channel an airflow for cooling from outside a vehicle to a body to be cooled is obtained. The cooling airflow intake structure includes: a power unit that generates a driving force for an automobile to travel; an undercover that covers, from a vehicle underside, a power unit chamber in which the power unit is placed; a cooling unit that is placed on a vehicle rear side of the power unit; a first duct that channels air to the cooling unit from a first inlet port that is formed opening toward a road surface in the undercover; and a second duct that channels air to the cooling unit from a second inlet port that is formed opening toward a vehicle front side in a bumper cover. The second duct is disposed between the power unit and the undercover in a vehicle vertical direction.

Abstract: A vehicle front portion structure is provided which can lengthen a wheel base without increasing the size of a vehicle body. A vehicle front portion structure is provided with a bumper reinforcement of a front bumper, a power unit that drives a front wheel arranged to a vehicle rear of the bumper reinforcement, and a cooling unit which is arranged at a vehicle front of a dash panel, and is arranged at a vehicle rear of the power unit.

Abstract: A vehicle frame structure includes a tunnel portion provided in a floor and left and right side members. Each of the side members includes a front side member, an inner member, and an outer member. The inner and outer members branch off from the front side member in a direction toward the rear of the vehicle. The inner member extends toward the rear of the vehicle along the tunnel portion. The inner members of the left and right side members are connected together by a plurality of connecting portions in the longitudinal direction of the vehicle at least at a location corresponding to a front portion side of the tunnel portion. These connecting portions break when a front impact load is input to at least one of the side members.

Abstract: A vehicle body structure is provided capable of reducing load borne by front-rear members. A vehicle front portion structure 10 includes: a pair of side frames 12, each extending in the vehicle front-rear direction and arranged parallel to each other at positions in the vehicle width direction; a dash panel 20, disposed at a position that is separated toward the rear in the vehicle front-rear direction from the front end portions 12A of the pair of side frames 12, and extending in the vehicle width direction and in the vehicle vertical direction; a division plate 25, disposed toward the front in the vehicle front-rear direction from the dash panel 20; an impact absorbing member 26, provided between the dash panel 20 and the division plate 25 so as to be able to transmit load in the vehicle front-rear direction; and support pillars 14, provided so as to be able to transmit load toward the rear in the vehicle front-rear direction to each of the side frames 12 and the division plate 25.

Abstract: A webbing guide mechanism includes an upper webbing guide (58) and a lower webbing guide (60) that are disposed on the side portion of a seat back (30) of a front seat (24) that is a tumbling seat. A webbing (50) is wound in a looped manner on these guides (58, 60). The webbing (50) is pulled forward and a loading/unloading space (78) is easily enlarged by sequentially changing the seat back (30) from a standard state to an inclined state and then to a tumbled state. According to the invention, a webbing guide mechanism is provided which can easily secure, without troubling a passenger, loading/unloading space behind the front seat (24) when the passenger climbs into or out of the space or when the passenger loads items into or unloads items from the space.

Abstract: A lock mechanism which is capable of selecting a locked state or an unlocked state with respect to a seat fixing member is disposed on a rear leg portion of a seat. A hook portion is formed at each of a front portion and a rear portion of an opening portion of a notch formed in a front leg portion of the seat. A projection of a base hook which is swingably connected to the front leg portion is engageable with an engaging projection of a cam that is swingably connected to the front leg portion. The cam is engaged with a spring for urging the cam in a direction in which the engaging projection engages with the projection. Due to a hook portion of the front leg portion passing beneath a pin which is disposed in a rail and which has reached a bottom of a groove in the base hook, the seat and the pin are prevented from becoming disengaged from each other.
