Scroll compressor

A scroll compressor, comprising:

• a housing;
• a first scroll disposed in the housing;
• and
• a second scroll disposed in the housing and facing the first scroll to form a compression chamber between the first scroll and the second scroll, the second scroll being configured to rotate relative to the first scroll about a driving axis of the scroll compressor to compress fluid in the compression chamber,
• the second scroll having:
• an end plate formed in a disc shape extending orthogonally to the driving axis, the end plate having a first surface facing the first scroll and a second surface located opposite to the first surface;
• a spiral element integrally formed with the end plate and spirally protruding from the first surface toward the first scroll in a direction in which the driving axis extends;
• and
• an adjustment portion formed in the end plate and recessed from the second surface toward the first surface, the adjustment portion adjusting a center-of-gravity of the second scroll, wherein
• the adjustment portion has:
• a bottom surface extending in parallel with the second surface;
• a peripheral surface enclosing the bottom surface and extending in the direction in which the driving axis extends;
• and
• a connection surface located between the bottom surface and the peripheral surface, and connecting the bottom surface to the peripheral surface,
• the peripheral surface has a first peripheral surface located close to an outer periphery of the end plate and a second peripheral surface located closer to the driving axis than the first peripheral surface and facing the first peripheral surface in a radial direction of the end plate, and
• a length of the second peripheral surface in the direction in which the driving axis extends is shorter than a length of the first peripheral surface in the direction in which the driving axis extends.
