PURPOSE:To prevent a plastic vane for use in opening or closing a cold air outlet from being deformed. CONSTITUTION:A plastic vane 4 capable of being opened or closed and swung within a predetermined range when it is released is supported at a cold air outlet 3 at its both ends of a longitudinal rear side and at the same time a holding piece 11 exposed at the cold air outlet 3 for restricting an excessive bending of the vane 4 by receiving the rear surface of the vane 4 is disposed at a central part of a rear side opening edge of the cold air outlet 3. In this way, the bending of the vane is restricted by the holding piece and a permanent strain caused by a load of the vane can be avoided. |
