Claims

[Claims for Utility Model Registration] 1. Printing on a flat electrically insulating substrate 2 such that a plurality of resistors R are connected in series to change the rotation speed of the fan motor M in multiple stages by changing the total resistance value. The flat resistance FR is connected to the air passage 12 near the air outlet 16 of the fan scroll 11.
In the air blowing control device for an automobile air conditioner installed in a vehicle, the flat resistance FR
is parallel to a position spaced apart by a predetermined length l from the flat side wall 11c facing the nose portion 23 of the fan scroll 11, or the inclination angle θ with respect to this parallel position is ±1.
A ventilation control device for an air conditioner for an automobile, characterized in that it is installed on a bottom wall 11a adjacent to the side wall 11c so as to have an angle of 0 degrees. 2. The air blow control device according to claim 1, wherein the side wall 11c faces a dash panel 17 of an automobile.
