A bridge-shaped frame member 11 is disposed on a front side frame 2 in front of a suspension tower 5 so as to extend vertically and stride over a No. 4 mount M4 . 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.

In an air intake system for a multi-cylinder in line engine (2) mounted transversely in an engine compartment (1), intake branch pipes of an intake manifold (4,9) extended rearward of the vehicle over the cylinder head cover (3) from intake ports formed in the vehicle front side face of the engine are respectively offset frontward of the engine against spark plug units (31) projecting upward from the cylinder head cover (3), and at least a part of each intake branch pipe (41,91) overlaps vertically when viewing the engine form the rear side. An air cleaner unit (6,10) is arranged above a transmission (2) on the rear side of the engine (2).

A first split-bracket 6 is joined to a first tube-shaped frame 2 by laser welding. A second split-bracket 8 is joined to an end portion of a second tube-shaped frame 4 by the laser welding. The second tube-shaped frame 4 equipped with the second split-bracket 8 is assembled to the first tube-shaped frame 2 equipped with the first split-bracket 6. A second flange 606 of the first split-bracket 6 and a second flange 806 of the second split-bracket 8 are joined temporarily by spot welding. The second flange 606 of the first split-bracket 6 and the second flange 806 of the second split-bracket 8 are joined by continuous welding with laser welding. Accordingly, the tube-shaped frames can be connected properly without forming any hole at a wall of the tube-shaped frame, ensuring the rigidity of the connection portion of the tube-shaped frames.

In a vehicle body structure in which a vehicle-body frame of front side frames 2 with a flangeless structure having a rectangular closed cross section and a vehicle-body panel of a dash panel 1 are welded, a concave portion 15 is formed at a specified portion of the vehicle-body panel to which the vehicle-body frame is welded so as to be concaved toward one side which is opposite to a disposition side of the vehicle-body frame and extends in its longitudinal direction, a temporary connection portion 16 which temporarily connects the vehicle-body frame to a side of the concave portion 15 is formed, and a laser welding portion 17 which connects the vehicle-body frame to the vehicle-body panel is formed near the temporary connection portion 16 so as to extend along the longitudinal direction of the vehicle-body frame.

A frame body 11 comprises a first face portion 11a on which a compressive force acts in case a load F is applied, a second face portion 11b on which a tensional force acts, and third face portions 11c, 11d which connect the first and second face portions 11a, 11b. The third face portions 11c, 11d are respectively equipped with a reinforcing member 12 which comprises a base portion 12a which is away from the frame body 11 and plural base portions 12b which project from the base portion 12a and are joined to the frame body 11. The convex portions 12 have plural convexities which are arranged so as to extend both in the longitudinal and sectional directions of a frame 1.
