    摘要： PROBLEM TO BE SOLVED: To provide a structure capable of securing strength while making thickness of a hollow circular tubular steering column thinner partially.SOLUTION: By performing drawing processing on a front end of an iron-based cylindrical member 19, an inner diameter of a front end surface is made smaller than that of a part positioned on the inner diameter side of a part forming a rear end surface of a body part 18. In addition, a part near the front end in the cylindrical member 19 is inserted into an insertion hole 25 opening toward an outer surface 24 of a mold 23, the part near the front end is projected toward inside of the mold 23. Molten metal of light alloy is fed into the mold 23, so as to mold the body part 18. After taken out from the mold 23, a cutting process is performed to an inner diameter part of a front end inner peripheral edge projecting toward an inner part of a radial direction in the cylindrical member 19 and the body part 18 so as to make an inner diameter of at least the part near the front end in the cylindrical member 19 equal to or more than that of the body part 18.

    摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing an aluminum base composite material matter. SOLUTION: This method of manufacturing the aluminum base composite material matter includes: a first step where a semi-solid-like aluminum base material is formed; a second step where a semi-solid-like mixture is obtained by adding reinforcing nano-particles to the semi-solid-like aluminum base material; a third step where the semi-solid-like mixture is made into a liquid state by heating; a fourth step where the mixture in the liquid state is processed ultrasonically; and a fifth step where the aluminum base composite material matter is obtained by cooling the mixture in the liquid state.
