PROBLEM TO BE SOLVED: To provide a lobe mixer for a jet stream in which an internal flow of high speed and an external flow of low speed are sufficiently mixed, a vibration with high stress and displacement hardly occurs, and a long life and a low noise are made consistent. SOLUTION: The lobe mixer for a jet stream is provided with: a cylindrical partition wall 22 partitioning the internal flow of high speed and the external flow of low speed; a lobe part 24 provided at a downstream side of the partition wall, having a cross section of waveform and molded to a large shape at the downstream; and a connection reinforcement member 26 provided between side walls of lobe radially extending from the lobe part and connecting the adjacent side walls 24a of the lobe. The connection reinforcement member 26 is a thin member along a stream line of a fluid flowing between the side walls of the lobe. COPYRIGHT: (C)2003,JPO
