Co-rotating scroll compressor

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 spiral 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 space;
• 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
• the driving-side scroll member includes a first driving-side scroll portion, a second driving-side scroll portion, and a wall fixing part, the first driving-side scroll portion including a first driving-side end plate and a first driving-side wall and being driven by the driving unit, the second driving-side scroll portion including a second driving-side end plate and a second driving-side wall, and the wall fixing part performing fixing while a front end in a rotation axis direction of the first driving-side wall and a front end in the rotation axis direction of the second driving-side wall face each other, and
• the driven-side scroll member includes a first driven-side wall and a second driven-side wall, the first driven-side wall being provided on one side surface of the driven-side end plate and engaging with the first driving-side wall, and the second driven-side wall being provided on another side surface of the driven-side end plate and engaging with the second driving-side wall.
