ロール圧縮機。 a casing, a drive shaft rotatably provided on the casing, an orbiting scroll rotatably provided on the drive shaft and having a spiral wrap portion erected on an end plate; A fixed scroll having a spiral wrap section erected on an end plate so as to overlap the wrap section of the orbiting scroll and form a compression chamber while rotating, and a fixed scroll for discharging air compressed in the compression chamber. In a scroll compressor comprising a discharge port provided at the center of the orbiting scroll and a suction port provided at a position near the end of each of the wrap portions away from the discharge port, The gap between the tip of the tooth of each lap part and the sliding surface of the end plate is made a uniform minute gap from the position of at least 180 degrees from the end position of the minute gap to the winding start position of each lap part. The gap between the tip of the tooth of the lap part and the sliding surface of the head plate is formed to increase at an increasing rate proportional to the temperature rise during gas compression, or at an increasing rate approximating the temperature rise. A scroll compressor characterized by:
