To provide a liquid receiver which enables improvement of brazeability between a tank member and a base member.SOLUTION: A liquid receiver 4 includes: a tank member 24 which has a cylindrical shape in which an upper end is closed and a lower end opens and includes an inner peripheral surface that is a cylindrical surface; a base member 23 having a cylindrical shape in which upper and lower ends open; and a plug fitted in the base member 23. The base member 23 is provided with: an insertion part 33 which has an outer peripheral surface that is a cylindrical surface and is inserted into the tank member 24; and a flat surface which continues into the outer peripheral surface of the insertion part 33 and is located at an exterior part of the tank member 24. A linear knurled part 29 is formed on the outer peripheral surface of the insertion part 33. The insertion part 33 is press-fitted into a lower end opening of the tank member 24 to form a gap between a lower end surface of the tank member 24 and a flat surface of the base member 23 and further form a gap 40 between a groove part 29b of the knurled part 29 of the insertion part 33 and the inner peripheral surface of the tank member 24. Brazing fillets 43 are formed at the gaps 40.SELECTED DRAWING: Figure 5
【課題】タンク部材とベース部材とのろう付性が向上した受液器を提供する。【解決手段】受液器4は、上端が閉鎖されるとともに下端が開口した筒状であり、かつ内周面が円筒面であるタンク部材24と、上下両端が開口した筒状であるベース部材23と、ベース部材23内に嵌め入れられたプラグとからなる。ベース部材23に、外周面が円筒面でありかつタンク部材24内に挿入される挿入部33と、挿入部33の外周面に連なるとともにタンク部材24の外部に位置する平坦面とを設ける。挿入部33の外周面に平目状のローレット目29を形成する。挿入部33をタンク部材24の下端開口内に圧入し、タンク部材24の下端面とベース部材23の平坦面との間に隙間を形成し、さらに挿入部33のローレット目29の溝部29bとタンク部材24の内周面との間に隙間40を形成する。両隙間40にろう材フィレット43を形成する。【選択図】図5
