Co-rotating scroll compressor and method of assembling the same

A co-rotating scroll compressor, comprising:

• a driving-side scroll member that is rotationally driven by a driving unit and includes a spiral driving-side wall disposed on a driving-side end plate;
• a driven-side scroll member that includes a driven-side wall corresponding to the driving-side wall, the driven-side wall being disposed on a driven-side end plate and engaging with the driving-side wall to form a compression chamber;
• and
• a synchronous driving mechanism that transmits driving force from the driving-side scroll member to the driven-side scroll member to cause the driving-side scroll member and the driven-side scroll member to perform rotational movement in a same direction at a same angular velocity, wherein
• positioning pins that position a phase of the driving-side scroll member around a rotation axis are provided at two positions around the rotation axis at a front end of the driving-side wall in an axis direction, and dummy pins that are provided at equal angular intervals around the rotation axis with the positioning pins are provided at one or more positions, and/or
• positioning pins that position a phase of the driven-side scroll member around a rotation axis are provided at two positions around the rotation axis at a front end of the driven-side wall in an axis direction, and dummy pins that are provided at equal angular intervals around the rotation axis with the positioning pins are provided at one or more positions.
