す。First, at the lower end of the wave-eliminating plate 2, a mounting piece 3 extending in the horizontal direction is provided.
Are connected in series via a horizontal U-shaped buffer portion 4. As shown in FIG. 3, the attachment piece 3 is formed in advance in a mountain shape having a base end portion a and a tip end portion c as a mountain hem and a center portion b as a mountain top, and the base end portion a and the tip end portion thereof are formed. c is placed on the inner surface of the tank bottom wall 1a, and spot welding is performed on the tank bottom wall 1a while bending the central portion 6 by a pair of upper and lower electrodes 5 and 6 of the spot welding machine (see FIG. 2). The spot weld portion is shown by reference numeral 7.
