Abstract:
To provide a lightweight and easy-to-use wave tube while maintaining linearity during straight piping.SOLUTION: A wave tube 100 according to the present invention includes a bellows tubular portion 105 in which a bellows convex portion 101 projecting outward in the radial direction and a bellows concave portion 102 recessed inward in the radial direction are continuous along a pipe axis, and that has a substantially uniform thickness in the circumferential direction, and a plurality of ridges 110 that are raised from the inner peripheral portion 106 of the base 105 inward in the radial direction at heights h1 and h2 so as to partially form a relatively thick portion in the circumferential direction, and extend in the elongated direction at intervals in the circumferential direction.
