<p>PROBLEM TO BE SOLVED: To provide a resister for reducing speed of leaked wind at the time of fin shut.SOLUTION: Several vertical fins 6 arranged side by side in a retainer of a resister have a protrusion 7 protruded along an end part 6B of a vertical fin 6 near a surface 6A positioned at an upstream side in an aeration direction W of the retainer at the time of fin-shut and having a side surface 7A formed with "return-back" part facing toward the end part 6B of the vertical fin 6 near the surface 6A. Leaked wind (refer to a line F) generated from between the surface 6A and the end part 6B of the vertical fin 6 near the surface 6A changes its direction by the "return-back" part formed at the side surface 7A of the protrusion 7 and does not merge with another leaked wind. Accordingly, since each of the leaked winds is uniformly dispersed over an entire surface of a bezel, it is possible to reduce speed of leaked wind at the time of fin-shut.</p> |
