動作の原因となる。(Problems to be Solved by the Invention) In the conventional method of manufacturing a traveling wave tube device as described above, since the fitting gap is small, the high frequency acting part 2 of the tube body is very long and narrow. Due to its flexibility, if there is some bending in the sealed and assembled state of the electron gun part 1, high-frequency action part 2, and collector part 3, the electron gun part 1 can be fixed with the fixing fitting 10. Since it is forcibly pressed against the shaft in the radial direction, the high frequency acting section 2 is fixed to the base plate 9 in a bent state. As a result, a biased load is applied to the main body of the traveling wave tube, causing unstable operation such as output fluctuations.
