A hybrid vehicle driving system includes: a generator; a motor; a case which accommodates the generator and the motor; and a power control unit for controlling the generator and the motor, the generator and the motor being disposed side by side on a same axis within the case. The power control unit is mounted on the case by connecting a unit-side generator connector and a unit-side motor connector which are provided on a bottom surface of the power control unit with a case-side generator connector and a case-side motor connector which are disposed on the case, directly and respectively. The case is fixed to a vehicle framework member via a mount member, and a fixing point where the case and the mount member are fixed together is disposed near the case-side generator connector and the case-side motor connector.

A dump truck includes: a vehicle body frame; a body supported by the vehicle body frame and configured to be raised or lowered; a plurality of tires provided to the vehicle body frame via a suspension; and a driving unit in a form of an electric motor configured to drive the tires, in which the vehicle body frame includes: supports respectively supporting an upper arm and a lower arm of a suspension arm of the suspension; and a hollow part at least partially in the vicinity of the supports, and the electric motor is fixed to the vehicle body frame while being housed in the hollow part of the vehicle body frame and supported by an inner surface of the hollow part.

A hollow vane structure for an active grille system 100 having a first piece 12 of the vane body 10 that includes a front side 14 and a back side 16. The first piece 12 has a concave cross-section extending from the front side 14 toward the back side 16. This concave section creates a hollowed inward section 18 on the back side 16 of the first piece 12. The first piece 12 also includes an edge surface 20 formed on the first piece which defines a perimeter of the hollowed inward section 18. A second piece 22 of the vane body is connected to the back side 16 of the first piece 12 and extends across the hollowed inward section 18 and is connected to the first piece 12 to at least the edge surface 20 on the back side 16 of the first piece 12.

A vehicle panel structure that includes a first panel that is provided to a vehicle, the first panel being made from a fiber reinforced resin and including a plurality of first beads extending along one direction, and a second panel that is disposed so as to face the first panel and that includes a plurality of second beads extending along another direction intersecting with the first beads.

A floor module is provided for installation in the rear area of a motor vehicle. A rear area of the floor module facing the tail of the vehicle includes a first plastic composition, and a front area facing away from the tail includes a second plastic composition, wherein the first plastic composition imparts a higher elastic deformability to the rear area than to the front area.

An auxiliary frame for supporting elements of a front suspension of a motor-vehicle includes two end supports for connection thereto of suspension elements and a structure which connects the end supports to each other. The connecting structure has a front beam and a rear beam which connect the end supports to each other. The rear beam has an arch-like configuration which extends substantially in a horizontal plane, with a central portion arranged in a forwardly spaced position. The front beam of the connecting structure has a configuration which is substantially straight and perpendicular to a vertical median plane of the auxiliary frame. The front beam and the rear beam are longitudinally spaced from each other and connected to each other by at least two lateral longitudinal arms spaced from each other and which have a configuration substantially straight and parallel to the vertical median plane of the auxiliary frame.

Provided is a vehicle door structure that enables manufacturing cost reduction and weight reduction. A vehicle door structure 1 includes a lock mechanism 40. The lock mechanism 40 locks sliding of a slide door 6 in a fully closed position in which the slide door 6 closes a door opening portion 4 and in a fully open position in which the slide door 6 fully opens the door opening portion 4. The lock mechanism 40 includes the portion to be locked 50 provided to the guided body 18 and the locking portions 60 and 70 provided to the slide rail 17. The portion to be locked 50 protrudes toward the locking portions 60 and 70 and is locked by the locking portions 60 and 70 in the fully closed position or the fully open position.

A vehicle door includes a lower part and an upper part designed as a window frame. The upper part includes several frame elements, which are joined together by spraying plastic onto the frame elements.

An overall knuckle is formed by a second carbon-fiber composite material, and a first carbon-fiber composite material is embedded in particular portions, whose rigidities are insufficient only with the second carbon-fiber composite material. The one particular portion is provided to a neck part, and the first carbon-fiber composite material is embedded in this particular portion such that continuous fibers thereof are orientated in a direction orthogonal to a central axis of a torsional load so as to enhance a torsional rigidity. The other particular portions are provided to the body part, and the first carbon-fiber composite material is embedded in these particular portions such that the continuous fibers thereof are orientated in a vertical direction so as to enhance a bending rigidity.

A vehicle lower-body structure includes a front pillar, including a front-pillar outer panel and a front-pillar inner panel, and a side sill, including a side-sill outer panel and a side-sill inner panel and joined to a lower portion of the front pillar. The front-pillar outer panel is joined to an outer surface of the side-sill outer panel. The front-pillar inner panel is held between the side-sill outer panel and the side-sill inner panel. The side-sill outer panel and the side-sill inner panel respectively include vertical beads in front of a reinforcement member disposed at a front portion of the side sill and below the front pillar, the vertical beads extending vertically.
