First convexities and second convexities are formed in opposing first wall surfaces and second wall surfaces of lead wire end portion holding grooves, and in holding coil ends that are housed in the lead wire end portion holding grooves with the first convexities and the second convexities, the first convexities and the second convexities are formed at positions that are offset with respect to each other in a circumferential direction and one end portions of the coil ends of the same phase that are connection portions are drawn out towards an outer diameter side from between the first convexities and the second convexities.

An ingot I made of a light alloy is produced using a continuous casting apparatus including a cylindrical water-cooled casting mold which is disposed immediately below a spout having an upward-turned molten metal receiving port and a downward-turned molten metal outlet, and which has an inside radius rlarger than an inside radius rof the molten metal outlet, and lubricating oil discharge passages provided below the spout to supply a lubricating oil to between the water-cooled casting moldand a molten metal m brought into contact with the water-cooled casting mold. In this production, a lubricating oil having a vaporization rate of 30% or more at 300&#xb0; is used, and an annular gas accumulation for spacing the molten metal apart from outlets of the lubricating oil discharge passages is defined below an annular protrusion of the spout by vaporization of the lubricating oil. Thus, it is possible to avoid the generation of a casting skin failure in a light alloy ingot due to the outlets of the lubricating oil discharge passages.

When a continuous casting is carried out while applying an electromagnetic agitating force to a molten metal of an aluminum alloy composition, the molten metal of the aluminum alloy composition has an Fe content in a range of 0.75% by weight &lE;Fe<2% by weight. Thus, a hard Fe-based intermetallic compound can be crystallized as a primary crystallized product, and an acicular intermetallic compound can be pulverized and finely divided by cooperation of the hard Fe-based intermetallic compound with the electromagnetic agitating force.

A cooling passage is formed to have a helical configuration so that a flow rate of a cooling medium supplied to the cooling passage is controlled to be in an optimum cooling region. Accordingly, the contact surface area and the cooling volume of cooling water are decreased respectively. Further, it is possible to stably obtain an optimum casting quality with ease.

An agitated continuous casting apparatus includes a spout having an upward-turned molten metal receiving port and a downward-turned molten metal outlet, a cylindrical water-cooled casting mold disposed immediately below the spout, and an agitator for applying an electromagnetic agitating force to the molten metal in the spout. The agitator has a function to form, in the spout, an upper area for moving the molten metal in a substantially radiate direction, and a lower area for rotating the molten metal in a circumferential direction. An upper area forming portion of an inner peripheral surface of the spout is formed into a tapered shape with its inside diameter gradually increased from its upper peripheral edge toward its lower peripheral edge. Thus, the molten metal moved in the substantially radiate direction to collide against the upper area forming portion can be moved toward the lower area, and crystallized products having a higher melting point in the molten metal can be spheroidized and collected into an outer periphery of a continuous casting material, and a shape retention effect of the crystallized products can be utilized. Therefore, the continuous casting material has a good rheologic property and an excellent shape maintaining property in its semi-molten state.

The external surface configuration of a portion of a mounted member that is joined to a mounting member includes, at a distal end position which first comes into contact with the mounting member when the mounted member is pressed against the mounting member, a curved surface bulged toward the mounting member. Other curved surfaces are bulged toward the mounting member with radii of curvatures larger than that of the curved surface and linking up with the curved surface.

A heated state-deciding apparatus and a thermocouple provided for a transport robot for detecting the temperature of a billet being transported by the transport robot, and a deciding member for deciding whether or not the billet is heated to be in a predetermined solid phase state on the basis of the detected temperature. Accordingly, it is possible to efficiently and accurately decide whether or not the solidus rate of the metal billet is good or bad, and it is possible to improve the productivity.

A hollow member whose internal surface is to be applied with composite plating is held in a condition in which a generatrix of the internal surface extends vertically. An electrode is inserted into the hollow member with a predetermined clearance to the internal surface of the hollow member. A composite plating liquid supply passage has a discharge opening which is in communication with an opening at a lower end of the hollow member. A gas is entrained in a form of bubbles into a composite plating liquid which is supplied into the clearance through the supply passage.
