PURPOSE:To enable any one of louvers to be fixed by cutting it off from drive of a motor by dividing the shafts of air-flow direction change-over louvers provided at a plurality of air outlet ports from shafts to be operated by the motor, connecting the shafts to be operated by the motor to one another with universal joints and detachably mounting the shafts of the louvers to the shafts. CONSTITUTION:In the case where, for example, air-flow direction change-over louvers 3a - d are made to work in linkage with one another, power transmission shafts 5a - d and connecting rods 4a - d are coupled together by universal joints 6, and a power transmission bar 2 and a driving motor 1 are mounted to one of the connecting rods so that the shafts 5a - d are reciprocatingly rotated by the drive of the motor 1. The shafts 5a - d are penetrated through the hollow shafts of the louvers 3a - d to permit them to freely move, and a louver fixing bush 7 fixed to the shafts 5a - d is mounted to one end of each of the louvers while a bush 8 fixed to a bearing 9 is mounted to the other end thereof so that each louver is not simultaneously held by both the bushes 7 and 8. Thus, when fitted to the bushes 7, the louvers rotate in agreement with the rotation of the shafts 5a - d and, when any of them are fitted to the bushes 8, such louvers are fixed to the bearings 9 without regard to the rotation of the shafts 5a - d. |
