In the conventional flow meter, one end of the pitot tube 13 is inserted into the pitot tube insertion hole 15a formed in the flow path tube 15 as shown in FIGS. 1 and 2, and then the band is formed on the support portion 12a protruding before and after the transparent body 12. (B) wrapped and fastened the entire outer periphery of the flow pipe 15. As described above, when fastening the band (B) is not possible to accurately tighten, and it is cumbersome to use a separate tool, and as time passes, the band (B) is loosened or the pitot tube of the flow path tube 15 by an external impact. A gap is created between the insertion hole 15a and the pitot tube 13, which causes the fluid to flow out, and again, the band B has to be tightened or newly joined, and the connection portion between the flow path tube 15 and the pitot tube 13 is connected. It is weak and has a problem of being easily broken when subjected to external shock.
