PROBLEM TO BE SOLVED: To provide an attachment structure of a compressor which can suppress noise generated by the vibration of an attachment face of a member to be attached.SOLUTION: A line component which reaches a center point O of a basic circle C0 from the basic circle C0 of a reference involute curved line Iv0 of a fixed scroll 22 when viewed from an axial direction of a rotation center axis is set as a first line component L1, a line component which extends from an attachment face Ef of an engine EG (member to be attached) to a normal line direction while passing through the center point O is set as a second line component L2, an attachment angle α formed between the line component L1 and the second line component L2 is set so as to satisfy either of 65°≤α≤155° and 245°≤α≤335, and a vibration direction in which a vibration component out of radial directions of the compressor and a normal lined direction of the attachment face Ef are displaced with respect to each other. By this constitution, it is suppressed that the vibration component which is liable to generate noise at the attachment face Ef is transmitted to the attachment face Ef, and the noise generated by the vibration of the attachment face Ef is suppressed. |
