Co-rotating scroll compressor

A co-rotating scroll compressor comprising:

• a housing;
• a driving scroll;
• a driven scroll;
• a driving mechanism;
• and a driven mechanism,
• the housing having a scroll chamber in which the driving scroll, the driven scroll, and the driving mechanism are accommodated,
• the driving mechanism having a stator and a rotor that encloses the stator and that is rotationally driven by the stator,
• the driving scroll being driven rotationally about a driving axis by the driving mechanism,
• the driven scroll being eccentric to the driving scroll and being driven rotationally about a driven axis by the driving scroll and the driven mechanism to follow the driving scroll, and
• the driving scroll and the driven scroll forming a compression chamber in which fluid is compressed by the rotational driving of the driving scroll and the rotational following of the driven scroll, wherein
• a projection body and a restricting body are provided in the scroll chamber,
• the projection body extends toward the driving scroll and the driven scroll in a direction in which the driving axis extends, is formed separately from the housing, and is attached to the housing with a gap between the projection body and the housing,
• the restricting body restricts the projection body from rotating relative to the housing,
• the stator is attached to the projection body,
• the driving scroll is supported rotatably about the driving axis by the projection body,
• the driven scroll is supported rotatably about the driven axis by the projection body,
• the restricting body has:
• a shaft member that is inserted into the housing and the stator;
• and
• a supporting member that is provided on an outer peripheral surface of the shaft member, and
• the supporting member supports the shaft member while elastically deforming between the shaft member and a specific member that is one of the housing and the stator.
