PROBLEM TO BE SOLVED: To provide high shock absorbency even when a duct main body has a complicated shape. SOLUTION: An air conditioning duct P1 is provided with a thermoplastic resin duct main body 1 having one wall 2 and the other wall 3 facing each other at an interval in the shock application direction (arrow direction) and a reinforcing member 6 having a plate type shock absorbing part 6a absorbing a shock. On the other side wall 3 in the duct main body 1, a slit 8 for inserting the plate type shock absorbing part 6a in the reinforcing member 6 is arranged in the longitudinal direction. The reinforcing member 6 is provided with a plate type mounting part 6b protruding to the both sides in one lateral side part of the plate type shock absorbing part 6a. The reinforcing member 6 is mounted to the duct main body 1 while abutting the back face of the mounting part 6b to the other wall 3, when the plate type shock absorbing part 6a is inserted via the slit 8 arranged on the other wall 3. |
