A liquid receiver connected to a header tank of a condenser, comprising:
- a tubular base member comprising:
- a base circumferential wall to define a base inner space having a base first opening and a base second opening opposite to the base first opening in a longitudinal direction;
- a refrigerant inflow hole which passes through the base circumferential wall and via which the header tank is in communication with the base inner space so that refrigerant flows into the liquid receiver;
- a refrigerant outflow hole which passes through the base circumferential wall and via which the header tank is in communication with the base inner space so that the refrigerant flows out of the liquid receiver, the refrigerant outflow hole being provided between the refrigerant inflow hole and the base first opening in the longitudinal direction;
- and
- a female screw provided in an inner circumferential surface of the base circumferential wall and between the refrigerant outflow hole and the base first opening in the longitudinal direction;
- a tubular tank member comprising:
- a tank wall to define a tank inner space having a tank first opening and a tank closed end opposite to the tank first opening in the longitudinal direction, the tank first opening being connected to the base second opening so that the tank inner space is in communication with the base inner space;
- a plug comprising:
- a plug circumferential wall to define a plug inner space having a plug opening and a closed bottom opposite to the plug opening in the longitudinal direction;
- a plug end at an end opposite to the plug opening in the longitudinal direction;
- the plug being fitted into the base member along the longitudinal direction from the base first opening so that the plug opening is provided between the refrigerant inflow hole and the refrigerant outflow hole in the longitudinal direction and so that the plug inner space is in communication with the base inner space;
- a communication hole which passes through the plug circumferential wall and which is provided between the refrigerant inflow hole and the closed bottom in the longitudinal direction to be aligned with the refrigerant outflow hole;
- and
- a male screw provided in an outer circumferential surface of the plug circumferential wall and between the communication hole and the plug end in the longitudinal direction;
- a first seal member provided between the inner circumferential surface of the base member and the outer circumferential surface of the plug, between the base first opening and the female screw in the longitudinal direction, and between the plug end and the male screw in the longitudinal direction;
- and
- a second seal member provided between the inner circumferential surface of the base member and the outer circumferential surface of the plug, between the refrigerant inflow hole and the refrigerant outflow hole in the longitudinal direction, and between the plug opening and the communication hole in the longitudinal direction.
