従い圧縮空間１３の圧力が上昇する。Next, the compression mechanism of the scroll compressor will be explained. The rotational movement of the shaft 11 accompanying the rotation of the electric motor section 2 is transmitted to the orbiting scroll 6 via the boss section 11a and the protrusion section 10, but due to the action of the rotation prevention mechanism 6, the orbiting scroll 6 does not rotate on its own axis and becomes a fixed scroll. It rotates around the center of the involute No. 4 as the center of rotation. At this time, the end sb' of the wrap 6b of the orbiting scroll 5 is in contact with the wrap 4b of the fixed scroll 4, and the end 4b' of the wrap 4b of the fixed scroll 4 is in contact with the wrap 6b of the orbiting scroll 6. The state is that suction is complete, and as the orbiting scroll 5 revolves, the wraps 4b and 5b
As the two contact points approach the center of the involute, the pressure in the compression space 13 increases.

１６を介して冷却システム（図示せず）に吐出される。By the compression mechanism of this scroll compressor, the refrigerant sucked from the suction pipe 15 through the suction hole 9 is compressed and
The liquid is once discharged into a closed casing via a discharge pipe 16 and then discharged to a cooling system (not shown).

接触摺動する。In this compression stroke, the end plates 4a, 5a and wraps 4b, 5b of the fixed scroll 4 and the orbiting scroll 6 are deformed due to pressure load and thermal load. Further, the key groove portion 6C of the end plate 6a of the orbiting scroll 5 slides in contact with the rotation prevention mechanism 8.

向上することが一般的である。However, as for the material of the orbiting scroll 6, ferrous metals such as cast iron are generally used conventionally, but especially when rotating a scroll compressor at high speed using an inverter drive device, etc., it is necessary to reduce the centrifugal force of the orbiting scroll 5 as much as possible. In order to reduce this, it was necessary to use an aluminum alloy instead of iron-based metals, which have a heavy specific gravity. Therefore, it is necessary to reduce the bone shape and improve the wear resistance of the sliding parts. For this purpose, when using an orbiting scroll made of aluminum alloy, the projections
There is a method of press-fitting and fixing the bushing 10a to o, and attaching a receiving plate 6d to the part that contacts the thrust holding mechanism 14, but the key groove part 6C, which is the sliding part with the rotation prevention mechanism 6, is made of iron-based metal. It is common to improve wear resistance and material strength by forming a
