PURPOSE:To obtain an easy selection of an oscillation of fins in a fin driving equipment of an air conditioning unit for vehicles, by connecting guide-rotor grooves, consisting of more than one patterns and a connecting groove, to a plural number of fins through a guide pin. CONSTITUTION:The leftward rotation of a small type motor 11 rotates a guide roller 7 rightward through a reduction gear 12. At this time, a guide-pin 6 moves tracing a pattern 8a, being oscillated right and left as the roller rotates, while fins oscillate simultaneously through a common link 2b. Next, rightward rotation of the motor 11 rotates the guide rotor 7. In this process, the guide-pin 6 moves tracking the right side of the patterns 8a shown at left, whose waveform period is short, enters a connecting groove 8c, and moves to a pattern 8b shown at right, whose waveform period is long, which oscillates the fins according to the other waveform pattern 8b. Next, if the direction of the motor 11 is reversed, the movement of fins returns to the old pattern 8a. |
