摘要： Swivelling conduit for diverting the air to be fed into the passenger space of a motor vehicle. Said conduit includes two aligned and spaced trunnion mountings (20, 22) arranged on a fixed structural element, preferably on the wall of an air duct (10). The trunnion mountings have one bearing socket (24) connected with one of the two elements and one bearing spigot (28) connected with the other element. Both bearing elements have locating faces or counter-locating faces (32, 34) that limit a relative movement of the two bearing elements towards each other in the direction of the swivelling axis. The bore wall area of each bearing socket, cooperating with a lateral area of its corresponding bearing spigot, guides both structural elements radially towards the swivelling axis. In order to eliminate from said trunnion mountings in a simple, cost-effective manner both the axial play, which is very difficult to eliminate, and the radial play, which cannot be easily avoided, at least one of the cooperating surfaces (32, 34 or 46, 48) of the bearing elements has at least one elastically deformable section (50 or 60), which, when it is not tensioned, extends over the pofile which it engages after installation, when it is tensioned.
