Abstract: An air delivery system includes a drain valve. The drain valve includes a flexible valve body, and a base portion. The valve body includes a valve main portion having a substantially disk-like and conical surface-like shape. The base portion includes a drain hole, and a ring-like region on a surface of the base portion. The ring-like region has a diameter which is smaller than a diameter of the valve main portion, and surrounds the drain hole. The valve body is fitted to the base portion such that the valve main portion covers the drain hole. When the drain valve is closed, the base portion abuts against the valve main portion at the ring-like region, and a peripheral portion, of the valve main portion, which is located in the outer periphery portion than the ring-like region, is spaced apart from the surface of the base portion.

Abstract: An air duct of this disclosure includes: a tubular duct body formed from a non-air-permeable material; and a tubular opening end member formed from an air-permeable material. The opening end member is integrated with an end portion of the duct body so as to extend a duct wall of the duct body. D representing a diameter of the opening end member and L representing a length thereof satisfy a relationship 0.1D?L?1.5D. An air permeability of the air-permeable material is in a range of 0.3 to 100 sec/300 cc.
