Claims

[Scope of utility model registration request]

In a vehicle air conditioner in which a plurality of branch ducts are connected to a main duct to distribute cold air or warm air to various parts of the vehicle interior, the outer peripheral surface of either or both of the main duct or the branch ducts is coated with a heat insulating material. Alternatively, a structure of a vehicle duct which is covered with a heat-insulating space, whose outer peripheral surface is covered with a heat-shrinkable resin, and where the heat-shrinkable resin is thermoset in whole or in part.
