摘要： A press die and a processing method of the press die surface, and a manufacturing method of a vehicle body of an automobile, are capable of maintaining a high non-defective product rate of works after press processing, even in a case in which foreign matter such as iron filings and the like have adhered to a die surface. A press die for sheet metal forming has a multitude of concave portions on a die surface, and has a roughness (Ry) of a die surface on which the multitude of concave portions has been formed of 30 to 38 μm.

摘要： A fuel injection nozzle includes a lift piece located on the side of a nozzle needle. A protrusion of the lift piece and the distal end of a push rod are held by a spring seat with a specified clearance therebetween as a prelift. The adjustment of the prelift can be performed only by taking out the lift piece to be adjusted, so that the adjusting work of the prelift, accompanied with disassembly of the fuel injection nozzle becomes easy and fuel injection characteristics are improved.
