PROBLEM TO BE SOLVED: To uniformize discharged air and to lower pressure loss. SOLUTION: A blowing nozzle is provided with a slit-like discharge port 15 in the longitudinal direction of a long cylindrical main body part 11 and a supply port 12 at one end part of the main body part 11 to blow air supplied from the supply port 12 belt-likely from the discharge port 15. The discharge port 15 is formed at a tip part of a discharge port part 13 projected in the discharge direction of air from the main body part 11, a pair of belt-like flow straightening plates extending in the back surface side of the main body part toward the inside of the main body part 11 from the inside of a root part of the discharge port part 13 are provided to face each other. A plurality of air through holes are provided in the flow straightening plates to keep the static pressure in the main body part 11 uniform. The whole of the main body part 11 and the discharge port part 13 is manufactured from a belt-like steel sheet by press work forming. COPYRIGHT: (C)2003,JPO
