Abstract:
1. A scroll compressor comprising: a fixed scroll, which is fixed in position and has a spiral-shaped wall body on one side face of an end plate; a swiveling scroll, which has a spiral-shaped wall body on one side face of an end plate, being supported by engaging of the wall bodies so as to revolve in a swiveling movement since the swiveling scroll is prevented from rotating; top edges of the wall bodies being divided at one or more points, the height at each point being low on the center side of the spiral direction and becominghigh on the outer side, thereby forming a step; one side face of the end plates similarly being divided at one or more points, the height at each point being high on the center side of the spiral direction and being low on the outer side, thereby forming a step in correspondence with each point; and a covering material, provided on a join wall face which joins adjacent points on a side face of each of the end plates, the covering material being worn away by the sliding of a join edge, which joins the adjacent points on the top edges, so as to increase airtightness between the join edge and the join wall face, wherein the covering material is made of material selected from a group consisting essentially of soft covering material, molten or plated metal, iron phosphate, and molybdenum disulfide.
