摘要： PROBLEM TO BE SOLVED: To improve the productivity and reduce the production cost of a casting by realizing the thinning and lightening of the casting, then preventing or suppressing the breakage of sand cores caused by molten metal and facilitating the removal of core sand after casting.
SOLUTION: A steering head turnably supporting a steering shaft of a steering mechanism supporting a front wheel in a motorcycle is produced by die casting wherein molten metal is poured into a cavity 60 formed of a mold 50 provided with a sand core 51 forming a first hollow part and a metal core 52 forming a through-hole for inserting the steering shaft. The flow velocity of the molten metal at the outlet 63a of a gate 63 is adjusted into a range of 5 to 15 m/s. Further, the gate 63 is formed at a position where the molten metal directly after the passage of the gate 63 comes in contact with the metal core 52 inside the cavity, and is thereafter comes in contact with the sand core 51.

SOLUTION: Rapidly solidified Al alloy powder having a composition containing, by mass, 10 to 40% Si, and at least two or more metals selected from Fe, Co, Ni, Cr, Mn, Ti, and V by 3 to 11% in total, and the balance substantially Al is produced by an atomizing method. This powder is subjected to cold preliminary molding. This molding is heated at 430 to 530 deg.C so that the time for which the molding is exposed to a temperature of >=430 deg.C is limited within 5 hr, and the preliminary molding is subjected to hot plastic working into a dense body having a relative density of >=99%. This dense body is hot- forged into the rough shape of a piston, and the forging is subjected to mechanical working to obtain the piston as a finished product.
