Abstract
A driving force transmission mechanism configuring a vehicular air conditioning device includes: a driving lever coupled to a driving source; a following lever engaged with this driving lever and following this driving lever; and a rack rod engaged with the following lever and moving linearly. A first shaft and a link gear of the following lever are engaged with this rack rod. Moreover, by the driving lever and the following lever revolving under driving action of the driving source, a second shaft engaged with the link gear rotates, and the first shaft rotates via the rack rod. As a result, a first and a second air-mix door engaged with the first and the second shaft slide to undergo an opening/closing operation, and their opening extent characteristics are configured nonlinear under engaging action of a link pin and a link groove of the following lever.
