Abstract
A plurality of resistance-imparting portions (34A to 34E) are disposed adjacent to each other. A first contraction flow portion forming one of the resistance-imparting portions (34A to 34E) adjacent to each other is in communication with an enlarged diameter portion forming another resistance-imparting portion. First contraction flow portions (32AH to 32DH) forming the resistance-imparting portions (34A to 34E) adjacent to each other are disposed at different positions in a direction in which an outer frame member (31) extends.
