Abstract
In an air-conditioning refrigerant receiver having an annular clearance defined between an outer periphery of a lower cover supporting a contained assembly from the below and an inner periphery of a casing, a guide tube extends downwards to define an annular passage connected to the annular clearance between the guide tube and an inner surface of the casing, and is connected at its upper end to an outer periphery of the lower cover. Thus, a refrigerant, which has passed through the annular clearance, can be guided to a lower portion so as to quietly flow down along the inner surface of the casing, and hence, it is possible to inhibit to the utmost the refrigerant from leaving the inner surface of the casing and to become scattered, thereby more reliably preventing the occurrence of bubbling.
