Abstract
A scroll compressor includes a housing, a fixed scroll, and a movable scroll. A compression chamber is formed between the movable scroll and the fixed scroll. An opposing wall is located in and fixed to the housing. A back pressure region is formed between the opposing wall and the movable scroll, and a back pressure in the back pressure region urges the movable scroll toward the fixed scroll. An annular sealing member is arranged between the movable scroll and the opposing wall. The movable scroll includes a holding portion that holds the sealing member. The sealing member includes a rubber portion, which elastically deforms in the holding portion, and a resin portion, which is made of a material harder than the rubber portion. The resin portion at least partially projects out of the holding portion toward the opposing wall. The resin portion is in contact with the opposing wall.
