It is the matter of a perfuming device for vehicles to be put, through a suitable fork, on the tabs of the air grille. To always maintain the perpendicularity, the fork can take, by rotating on itself, eight different positions. The bottle of the perfumed essence is housed into a shell which is hermetically closed in its lower part and apt to contain any possible dripping from the wick. Bottle and shell, together, form the disposable recharge, without the hands come into direct contact with any essence leakage.
