In this structure, the liquid refrigerant sucked up from the inner pipe 1' is guided in two directions: the sight glass section 2 and the outflow hole 3. A conductive hole 5 is provided to communicate with the
It is necessary to form a through hole 5 from the side of the head body, which makes processing complicated.

量となる。(1) An inlet hole, a passage to the sight glass, and an outlet hole are bored in the head body of the receiver dryer, and a passage to the sight glass and the outlet hole are formed at the upper end of the inner pipe installed in the head body. (2) A lid portion is provided in which a tubular protrusion is fitted and fixed to the passage to the sight glass and the outflow hole of the head main body, and the lid portion is connected to the inner pipe having the conduction path. (3) The outer periphery of the upper end of the inner pipe having the conductive passage is fixed to the inner surface of the head body by caulking.According to the present invention, there is a conduction that communicates the passage to the sight glass with the outflow hole. Since the hole is removed from the head body and replaced by a conduit passage at the upper end of the inner pipe, the conventional complicated processing method of drilling a conduit hole from the side of the head body is omitted, while the head body The head of the main body is thinner and lighter.

考案の効果 (1) 従来例のごとくヘツド本体側面から導通孔を
穿設する必要がなくなり、加工が容易となつて
コスト低減が計れる。Effects of the invention (1) There is no need to drill through holes from the side of the head body as in the conventional case, making processing easier and reducing costs.

(2) ヘツド本体頭部の肉厚が薄くなるので軽量化
が計れる。(2) Since the wall thickness of the head body is thinner, weight can be reduced.
