Abstract: Described is a stopper including a filtering unit housed in an interior of a liquid receiver main body through which a refrigerant passes, a fixed portion that includes a screw portion that is screwed into an inner peripheral face of the liquid receiver main body, a sealing member in contact with the inner peripheral face of the liquid receiver main body, thereby preventing a leakage of a refrigerant to the fixed portion, and a movable connection portion provided between the filtering unit and the fixed portion for linking the filtering unit to the fixed portion in such a way that the filtering unit is not caused to follow a rotation of the fixed portion, and in such a way that the filtering unit is caused to follow an axial direction movement of the fixed portion.

Abstract: A stopper includes a filtering unit that is housed in an interior of a liquid receiver main body and through which a refrigerant passes, a fixed portion that includes on an outer peripheral face thereof a screw portion that is screwed into an inner peripheral face of the liquid receiver main body, a sealing member that is brought into contact with the inner peripheral face of the liquid receiver main body, thereby preventing a leakage of a refrigerant to the fixed portion from between the filtering unit and the liquid receiver main body, and a movable connection portion that is provided between the filtering unit and the fixed portion and links the filtering unit to the fixed portion in such a way that the filtering unit is not caused to follow a rotation of the fixed portion, and in such a way that the filtering unit is caused to follow an axial direction movement of the fixed portion.
