That is, the reinforcing rib 115 is provided so as to cross the fillet portion 113 formed along the core longitudinal direction (that is, the direction perpendicular to the paper surface of FIG. 8), and intersects the fillet portion 113.
  • a plurality of reinforcing ribs 115 are provided.
  • the plurality of reinforcing ribs 115 are arranged at predetermined intervals in the core longitudinal direction (that is, the direction perpendicular to the paper surface of FIG. 8).
  • the first duct plate 110 is prevented from being deformed at the fillet portion 113 by the reinforcing rib 115.
  • the reinforcing rib 115 is provided in the first duct plate 110 so as to cross the fillet portion 113.
  • the caulking plate 300 is positioned by the stopper portion 112 and the buffer rib 114, and the buffer rib 114 is provided at a position where the stress dispersion effect is maximized.
  • the caulking plate 300 may be positioned by any one of 114.
  • the buffer rib 114 is provided so as to correspond to the entire fillet portion 113, but the present invention is not limited thereto, and the buffer rib 114 may be provided so as to correspond to a part of the fillet portion 113. Good. For example, if there is a portion that is easily deformed in the fillet portion 113, the buffer rib 114 may be provided corresponding to the portion that is easily deformed.
  • the buffer rib 114 and the reinforcing rib 115 are provided integrally with the first duct plate 110.
  • the present invention is not limited thereto, and the buffer rib 114 and the reinforcing rib 115 are separated from the first duct plate 110. It is good.
