Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vane type compressor capable of making refrigerant in a suction chamber easily flow toward a shaft seal device.SOLUTION: A shaft seal device is provided with a first shaft hole 12h and a shaft 15. On a first wall part, a first communication passage 24 and a second communication passage 25 communicating between a suction passage and the first shaft hole 12h are provided in a penetrated manner. At least one of a first inlet 22 and a second inlet 23 is opened in the middle of the suction passage. The first communication passage 24 is opened on a side closer to a suction port 11a than the second inlet 23, and the second communication passage 25 is opened on a side farther from the suction port 11a than the first inlet 22.SELECTED DRAWING: Figure 2 【課題】吸入室内の冷媒が軸封装置に向かってより流れやすくすることが可能なベーン型圧縮機を得る。【解決手段】軸封装置は、第１軸孔１２ｈとシャフト１５との間に設けられる。第１壁部には、吸入通路と第１軸孔１２ｈとを連通させる第１連通通路２４および第２連通通路２５が貫設される。第１吸入口２２と第２吸入口２３の少なくとも一方は、吸入通路の途中に開口している。第１連通通路２４は、第２吸入口２３よりも吸入ポート１１ａに近い側で開口し、第２連通通路２５は、第１吸入口２２よりも吸入ポート１１ａから遠い側で開口している。【選択図】図２
