Abstract: Plate materials (37P) of an extended portion (37) are bonded to one another by substantially V-like crimped portions (50) in which center portions (50c) in a longitudinal direction (Y) protrude toward a base portion (38) while both end portions (50a) and (50b) in the longitudinal direction (Y) are being coupled to the plate materials (37P). Moreover, on a peripheral edge portion (60) in a lateral direction (X) of the crimped portion (50) of the plate material (37P) arranged on an outermost side in a direction away from the base portion (38) among the plurality of plate materials (37P) of the extended portion (37), an opening portion (53) that reaches an aperture (52) of the crimped portion (50) from the peripheral edge portion (60) is formed.
