PROBLEM TO BE SOLVED: To easily remove foreign matter when a liquid return hole 27a is clogged with the foreign matter, and check whether the liquid return hole 27a is actually clogged or not. SOLUTION: A female screw ring 24 is brazed to the lower end inner part of a tank chamber 18 storing liquid refrigerant separated into gas and liquid, and a lower cap 23 is detachably tightened to the female screw ring 24. A sub cap 27 having the liquid return hole 27a (ϕ1.0±0.1) for returning the liquid refrigerant stored in the tank chamber is fixed to the lower cap 23. With this structure, since the lower cap 23 is detachable from a tank body forming the tank chamber, when the liquid return hole 27a provided in the sub cap 27 is clogged with foreign matter, the foreign matter can be easily removed by removing the sub cap 27 together with the lower cap 23 from the tank body.
