Scroll compressor

A scroll compressor, comprising:

• a casing comprising a rotational shaft;
• a discharge cover fixed inside of the casing to partition the inside of the casing into a suction space and a discharge space;
• a first scroll that is revolved by rotation of the rotational shaft;
• a second scroll that defines a plurality of compression chambers together with the first scroll, the second scroll having an intermediate pressure discharge hole that communicates with a compression chamber having an intermediate pressure of the plurality of compression chambers;
• a back pressure plate that defines a back pressure chamber that accommodates a refrigerant discharged from the intermediate pressure discharge hole;
• a floating plate movably disposed on or at a side of the back pressure plate to define the back pressure chamber together with the back pressure plate;
• and
• a sealing member disposed on at least one of the floating plate or the back pressure plate to prevent the refrigerant within the discharge space from being introduced into the back pressure chamber or prevent the refrigerant within the back pressure chamber from being introduced into the discharge space, wherein the sealing member comprises a seal cover that contacts the back pressure plate or the floating plate while the floating plate slides, and a seal, in which a portion of the seal cover is accommodated, and wherein the seal cover has a friction coefficient less a friction coefficient of the seal.
