A product receipt facility is provided to maintain a product container to a place with little dust even though wind force of the clean air flowed by a clean air ventilation member is small. A product receipt facility comprises a travelling carriage(44), an article collection shelf(S), a product return carrier(V), a clean air ventilation unit(B), an air flow space and a air guide(37). The both end unit of the travelling carriage is open to make the air flow in and out. An air flow channel is formed at the travelling carriage. The air flow channel makes the air flow in and out through an opening between the both sides of the travelling carriage. The air flow channel is formed on the bottom of the travelling carriage with the downwardly opened concave groove shape. A rectifying plate(49) is installed within the air flow channel. The rectifying plate extends to upward and downward and the travelling direction of the vehicle.
