PURPOSE:To decrease the number of parts and to make easy the assembling work, by including a bias spring and a spring of a shape memory alloy (SME metal) in one side of a blow outlet. CONSTITUTION:A right bearing 4 is attached to the right wall of a grill 3 with a coil spring between a lever arm 6 and the right wall. Depending on temperature, a coiled SME metal 7 can expand or contract, and one end of the metal 7 is engaged with an attaching hole 6a of the lever arm 6 and the other end is engaged with an attaching hole 8a of a wind changing blade 8a. One end of a bias spring 9a is attached to an attaching hole 8d of the wind changing blade 8, the central part thereof is put on a right shaft 8b of the wind changing blade 8, and the other end is attached to an attaching hole 6c of lever arm so that it may be parallel with the wind changing blade 8. The one end of the bias spring is attached to the wind changing blade at the SME metal, the central section is put in the changing blade, and the other end is attached to the lever arm. |
