ル２に係合すると共にケーシング４側に係合する。A main shaft 5 rotated by a prime mover (not shown) is pivotally supported within the casing 4, and an orbiting scroll 2 is pivotally supported via a bearing 7 on a crankshaft 6 formed eccentrically at the tip thereof. The wrap 2A of the orbiting scroll 2 engages with the wrap 3A of the fixed scroll 3 integrally formed on the casing 4 side, and compresses the medium introduced into the space formed therebetween. The orbiting scroll 2 is slidably supported by the casing [11], and rotates and slides while being restrained from rotating by the Orgum joint 8. Note that the alternating bristles 8 engage with the orbiting scroll 2 and also engage with the casing 4 side.

is formed. On the other hand, the wrap 2A formed on the orbiting shumir 2 is formed in a spiral shape along an involute curve from its center, so that it is eccentric with respect to the central axis of the orbiting scroll (the center of the crankshaft 6). That is, the center of gravity of the orbiting scroll 2 is eccentrically formed. In order to eliminate vibrations and the like during operation, it is necessary to eliminate the eccentricity of the orbiting scroll 2. In the prior art, as shown in FIG. 4, a means for correcting the balance has been adopted by forming a missing portion 10 on the surface of the edge of the flange plate-like mirror plate 2B on which the wrap 2A is erected.

アップとなる欠点が生ずる。Problems to be Solved by the Invention As shown in FIG. 4, the orbiting scroll 2 has a wrap 2A,
A flange plate-like mirror plate 2B for installing this, and a wrap 2A.
The boss portion 20 is formed protrudingly on the opposite side and has a bearing hole 2D in the center thereof into which the bearing 7 is mounted. As described above, as the balance correcting means of the prior art, one is generally adopted in which the cutout part 10 is formed on the outer edge surface of the end plate 2B at a position opposite to the direction in which the chive 2A extends. As a result, the unbalance amount based on the wrap 2A is removed, but the missing portion IO is the dregs shown in the figure.
Since the height b is required, the flange mountain of the end plate 2B (-=
When the width of the flange (indicated by the dimension t) of the end plate 2B becomes thinner, the larger the width of the flange (indicated by the dimension t). This may cause an increase in production costs and costs. Also, press the end plate 2B from the side of the mirror 7 plate 2A! 1ili
Since the flange is pressed by the medium, if the thickness of the flange becomes thin, there is a risk of insufficient strength, which results in the disadvantage that the entire wall becomes thicker and the weight increases.

することにある。The present invention solves the above-mentioned deficiencies and the like, and aims to provide a scroll compressor which can eliminate the unbalance of the orbiting scroll, can be formed into a small single-sided scroll compressor, and can improve reliability.
問題点を解決するだめの子役
本発明はこのために、旋回スクロールのラップを立設支
持するフランジ板状の鏡板の外周部に。To solve this problem, the present invention provides a flange plate-like end plate for supporting the wrap of the orbiting scroll upright on the outer periphery thereof.

位置に形成される。As shown in FIGS. 1 and 2, the orbiting scroll 2 includes a flange plate-shaped end plate 2B, a wrap 2A erected from below on the lower side, a boss portion 2C protruding from the end plate 2B in the opposite direction to the wrap 2A, and a boss portion 2C. 6 or a wrap 2A formed from a bearing recess 2D for fitting a bearing, etc., which is recessed in the center of the bearing recess 2D, etc.
1 is formed so as to extend from the center of the end plate 2B along an involute curve and expand to the right in the figure. Therefore, the center of gravity of the orbiting scroll 2 is the end plate 2.
It is formed at a position eccentric to the right in the figure from the center of B (crankshaft center 2M).

構わない。It can be determined by theoretical calculation. The center of gravity of the orbiting scroll 2 coincides with its center, that is, the center of the bearing recess 2D (crankshaft center 2M) due to the recess 1. Furthermore, the concave portion 1 reduces the weight of the orbiting scroll 2. The concave portion l is not limited to the elastic curve as described above, but may be formed from a plurality of holes IA, IB, and Ic as shown in FIG. Unbalance amount can be removed and weight reduction can be achieved. Of course, it is also possible to use both the arcuate curve and the thank-you letter.

に伴う遠心力を低減することができる。Since the eccentricity of the orbiting scroll 2 is eliminated, the orbiting scroll 2 becomes crank I! Since it can turn smoothly around Ih6, stability is obtained, and the load due to eccentricity is reduced, improving reliability. Furthermore, since the concave portion l is formed within the wall thickness, there is no particular need for a wide flange surface as in the prior art, making it possible to reduce the size and weight, and reduce the centrifugal force associated with turning.
