PROBLEM TO BE SOLVED: To provide a good temperature control characteristic by suppressing dropping of temperature of harmonic air in a case where a hot air passage and a bypass passage are opened/closed with a louver damper containing a plurality of band-like plate materials to adjust the temperature of the harmonic air.SOLUTION: Inside a casing 15, there are provided a hot air passage side damper 40 which opens/closes a hot air passage R2, and a bypass passage side damper 30 for opening/closing a bypass passage R3. A rotational angle is, when a band-like plate material 31 of a bypass passage side damper 30 is rotated from a fully closed state to a fully opened state, set to be smaller than a rotational angle when a band-like plate material 41 of a hot air passage side damper 40 rotates from a fully closed state to a fully opened state.SELECTED DRAWING: Figure 1 |
