A scroll compressor 1 is provided with: an insertion hole 61 formed in the other surface of the base plate 31a of a stationary scroll 31; an injection port 62 having an inner diameter smaller than that of the insertion hole 61 and passing between the bottom 61a of the insertion hole 61 and one surface of the base plate 31a; an injection pipe 60 which passes through a closed container 10, is inserted in the insertion hole 61, and injects fluid into a compression chamber 35 through the injection port 62; and an annular damping member 63 having an outer diameter D11 greater than the inner diameter of the injection port 62 and disposed between the injection pipe 60 and the bottom 61a of the insertion hole 61. The injection pipe 60 is provided with: a large-diameter section 60b1 having an outer diameter D21 greater than the inner diameter D22 of the damping member 63, the large-diameter section 60b1 being in contact with the damping member 63; and a small-diameter section 60b2 having an outer diameter D22 smaller than the outer diameter D21 of the large-diameter section 60b1, the small-diameter section 60b2 being fitted in the damping member 63. The axial dimension L21 of the small-diameter section 60b2 is smaller than the axial dimension L11 of the damping member 63. |
