摘要： PROBLEM TO BE SOLVED: To provide a drainage structure of an engine hood easily and certainly removing salt water (water) attached in a gap at a front edge of the engine hood by the capillary action.
SOLUTION: The drainage structure comprises a water suction tube 20 sucking attached water W1 attached in the gap 18 and an air flow tube 21 passing travel wind C of a vehicle flowing into an engine room 17 through a grille. The air flow tube 21 is arranged extending in the vehicle length direction B on the engine room side of an inner panel 12, an end 20a of the water suction tube 20 faces the gap 18, and the other end 20b penetrates through the inner panel 12 to communicate with the air flow tube 21. This configuration sucks and removes the attached water by the principle of atomizing using the travel wind.

SOLUTION: The Al alloy sheet comprises 0.4-0.7% Mg and 0.8-1.2% Si, one or more of metals selected from 0.03-0.4% Mn, 0.01-0.4% Cr, 0.01-0.4% Zr, 0.01-0.4% V, 0.03-0.5% Fe, 0.005-0.2% Ti and 0.03-2.5% Zn, in which the content of Cu is controlled to ≤0.1%, and the balance substantially Al. In a region of 1/4 of the sheet thickness from the surface, cube orientation density is more than two fold of gross orientation density, and is four fold of that of a random sample. The Al alloy sheet has an electric conductivity of ≤54%IACS, and a mean crystal grain size of ≥4.5 in an ASTM number. Hot rolling is started at ≥370°C so as to obtain a sheet thickness of 1.0-8.0 mm and a finishing temperature of 180-350°C. Further, cooling is performed from the temperature range in the finishing of the hot rolling to ≤100°C at ≤100°C/min. Also, after cold rolling at a rolling ratio of ≥30%, solution treatment is performed under holding at ≥480°C for ≤5 min or without the holding, and cooling is performed to 50 to

摘要： PROBLEM TO BE SOLVED: To provide a self-piercing rivet capable of preventing buckling of the rivet and obtaining required and sufficient bonding strength. SOLUTION: This rivet is the self-piercing rivet 1 made of aluminum alloy and provided with a cylindrical shaft part 11 and a head part 12 forming a conical recessed part 121 at the center of an upper face 12a of the shaft part. When driving the rivet 1 into a member to be tightened, a diameter of the head part 12 is shrunk to the center side by the recessed part 121 substantially at the same time when the shaft part 11 starts to expand. The shaft part 11 can be easily expanded due to the shrinkage of the diameter of the head part 12 to obtain required and sufficient bonding strength. This rivet is favorable for tightening an aluminum alloy material 2 as a part to be tightened.

摘要： PROBLEM TO BE SOLVED: To provide an aluminum alloy self-piercing rivet preventing buckling at driving, and a fastening method using the self-piercing rivet. SOLUTION: This self-piercing rivet 1 is made of an aluminum alloy, and provided with a shaft portion 11 formed with a cutting edge portion 111 having a cutting edge function in a circumferential direction at a tip end, and a head portion 12 having a hole portion (an engaging means) for rotating the rivet 1. The fastening method comprises a first step wherein the rivet 1 is held to a rotating indenter by the hole portion 121, and the rivet 1 is driven in s fastened material while rotating the rivet by the rotating indenter; and a second step wherein the rivet 1 is further driven in the fastened material after stopping the rotations of the rivet 1. Since the first step driving the rivet 1 having the cutting edge function in the circumferential direction into the fastened material while rotating, pressing force added on the rivet 1 at driving can be decreased, so that buckling of the rivet 1 is prevented.
