PROBLEM TO BE SOLVED: To improve compression efficiency by enhancing the reliability of a function for sealing a compression fluid between a roller and a cylinder, in a compressor having a helical type compression mechanism portion.SOLUTION: A compressor 1 compresses a working fluid in a compression chamber 23 formed in a spiral shape by a blade 24 between a cylinder 20 and a roller 21. The compressor 1 is equipped with a permanent magnet 5 provided on a wall inside portion of a proximity part 2020 to which an outer peripheral wall 211 of the roller 21 contacts or comes most closely, of an inner peripheral wall 202 of the cylinder 20, when the roller 21 rotates to the cylinder 20. Between the proximity part 2020 on the inner peripheral wall 202 of the cylinder 20 and the outer peripheral wall 211 of the roller 21, a magnetic fluid is interposed by using magnetic force generated by the permanent magnet 5. |
