To provide a door driving device which achieves downsizing and improvement of assemblability while improving driving force transfer efficiency to a door provided at an air conditioning case.SOLUTION: A transmission shaft 34 which can transmit driving force from a driving part 20 to a first door shaft 30 which drives a first air mix door 24 and a second door shaft 32 which drives a second air mix door 26 is provided at an air-conditioning case 12. In the transmission shaft 34, a first face gear 46 is engaged with a first spur gear 40 of the first door shaft 30, and a second face gear 48 is engaged with a second spur gear 42 of the second door shaft 32. A driven gear 50 to which the driving force from the driving part 20 is transmitted is provided at a center part of the transmission shaft 34. The driving force of the driving part 20 is transmitted to the driven gear 50 of the transmission shaft 34 to cause the transmission shaft 34 to rotate to transmit the driving force to the first and second door shafts 30, 32.SELECTED DRAWING: Figure 2

    【課題】空調ケースに設けられたドアへの駆動力の伝達効率を高めつつ小型化及び組付性の向上を図る。【解決手段】空調ケース12には、第1エアミックスドア24を駆動する第1ドアシャフト30と、第2エアミックスドア26を駆動する第2ドアシャフト32とに対して駆動部20からの駆動力を伝達可能な伝達シャフト34が設けられる。伝達シャフト34は、その第1フェースギア46が第1ドアシャフト30の第1平歯車40へと噛合され、第2フェースギア48が第2ドアシャフト32の第2平歯車42へと噛合される。また、伝達シャフト34の中央部には、駆動部20からの駆動力が伝達される従動ギア50が設けられている。そして、駆動部20からの駆動力が伝達シャフト34の従動ギア50へと伝達されることで、この伝達シャフト34が回転して第1及び第2ドアシャフト30、32へと駆動力が伝達される。【選択図】図2
