A vehicle ventilation duct includes a duct body, a conduit, a sound absorption chamber, a transmission opening communicating the conduit with the sound absorption chamber, and an air-permeable member closing the transmission opening permeably. The duct body is disposed in a vehicle outer hull, and includes a frame having a ventilation opening opened to the outside of a vehicle and a valve element covering the ventilation opening openably and closably. The conduit is formed integrally with or independently of the duct body, is disposed on a vehicle-passenger-room side of the duct body, is communicated with the ventilation opening of the duct body, and is communicated with the inside of a vehicle passenger room, whereby enabling air inside and outside the vehicle to pass therethrough back and forth. Thus, the ventilation duct lets out air in the vehicle passenger room to the outside of the vehicle or vice versa.

A wheel cap is detachably joined to a disc wheel and having air discharge openings formed in the outer periphery thereof. The wheel cap has a plurality of radial fins provided for the reverse side of the wheel cap and formed from the wheel cap center toward the outside. Further, the wheel cap has an annular air suction opening, and a center plate disposed more adjacent to the center thereof as compared with the air suction opening. The inner distance between the innermost wall of the air suction opening and the center of the wheel cap is shorter than securing distance between a hub nut for securing the disc wheel to an axle hub and the center of the disc wheel.
