PURPOSE: To maintain reliability of a lip seal 19 by avoiding downgrading in the sealing quality of the lip seal 19 which seals a driving shaft 18 for rotating a swash plate 23.
CONSTITUTION: A main hole 36 is formed along the center line of a driving shaft 18, and a leading-in hole 38 is made open to a swash plate chamber 9 in the boss part 23a of the swash plate 23 and is formed so as to be communicated with the main hole 36. Besides, a leading-out hole 37 is made open to a suction chamber 9 in the driving shaft 18 and is formed near the lip seal 19 so as to be communicated with the main hole 36, by which a suction passage 40 for sucking refrigerant is formed. When the driving shaft 18 rotates, the leading-out hole 37 rotates in the suction chamber 9 while refrigerant is being led out.
