Abstract: A rotary compression mechanism includes: a shaft attached to a casing; a drive cylinder rotatably supported on the shaft; a rotor provided inside the drive cylinder; a transfer mechanism connecting the drive cylinder and the rotor in rotational motion at a constant speed; and a partition plate dividing a space defined between an inner periphery of the drive cylinder and an outer periphery of the rotor. The rotor has a second rotation center which is eccentric with respect to a first rotation center of the drive cylinder such that the outer periphery of the rotor is in contact with the inner periphery of the drive cylinder at a contact portion. The partition plate has a structure by which one end of the partition plate is let in and out in a vicinity of the inner periphery of the drive cylinder or in a vicinity of the outer periphery of the rotor.

Abstract: An attachment structure is for attaching a compressor to an attachment surface of an attachment target member. The compressor is a scroll type compressor and has a housing, a fixed scroll and a movable scroll. The housing is fixed to the attachment surface. The fixed scroll is fixed inside the housing and has a fixed-side tooth having a scroll shape. The movable scroll has a movable-side tooth having a scroll shape and engaging with the fixed-side tooth. The movable scroll revolves with respect to the fixed scroll. A central axis around which the movable scroll revolves is parallel with the attachment surface. A vibration direction, which is included in a radial direction of the compressor and in which a vibration component becomes largest, is different from a normal direction when viewed in an axial direction of the central axis.
