グのキー溝２４を形成している。(Prior Art) Conventionally, as disclosed in, for example, Japanese Unexamined Patent Publication No. 62-252636, and as schematically shown in FIGS. 5 and 6,
The mounting surface 22 of the fixed scroll and the support surface 21 of the movable scroll are formed on the frame 2 with a step equal to the thickness of the end plate of the movable scroll, and an Oldham ring key is provided that opens upward in the support surface 21. A groove 24 is formed.
前記キー溝２４は、オルダムリングを摺動自由
に受入れるもので、その摺動を案内するに必要な
長さを、前記架構２の径方向に確保している。 The keyway 24 is for freely slidingly receiving the Oldham ring, and has a length in the radial direction of the frame 2 necessary to guide the sliding movement.
一方、前記架構２の径は、コンパクト化等の要
請から、固定スクロールを支え、かつ、可動スク
ロールの回動を許容し得るに十分な小さな寸法と
している。 On the other hand, the diameter of the frame 2 is made small enough to support the fixed scroll and allow rotation of the movable scroll due to the need for compactness.
よつて、前記取付面２２と支持面２１との段差
部分を結ぶ突壁２３には前記キー溝２４の外方側
が一部重なることゝなつている。 Therefore, the outer side of the keyway 24 partially overlaps the projecting wall 23 connecting the stepped portion between the mounting surface 22 and the support surface 21.

のであつた。(Problem to be Solved by the Invention) However, as described above, since the outer side of the finishing locus L of the keyway 24 partially overlaps with the forming part of the protruding wall 23, the end mill E is moved toward the inner peripheral side of the frame 2. As the projecting wall 23 is moved toward the outer circumferential side from
The contact area of the end mill E suddenly increases at the formation site, and the resistance to rotation and movement of the end mill E increases accordingly, causing vibrations such as so-called chatter in the end mill E. The machining accuracy of the keyway 24 may deteriorate, or the end mill E
Problems such as a shortened lifespan may occur.
本発明は、以上のような問題点に鑑みてなした

る。(Means for Solving the Problems) In order to achieve the above object, in the present invention, the frame 2 is provided with a support surface 21 for the movable scroll 4, and the fixed scroll 3 is attached to the outer circumference of the support surface 21 at the end thereof. In a scroll type fluid machine in which a protruding wall 23 having a mounting surface 22 is provided, and a key groove 24 of the Oldham ring 8 that opens upward from the support surface 21 to the protruding wall 23 is formed, the outer side of the key groove 24 and The overlapping protrusion wall 23 has a size that includes the finished locus L of the keyway 24, and the mounting surface 2
The present invention is characterized in that a cut portion 25 is formed whose depth from 2 substantially matches that of the support surface 21.

のである。(Function) However, in the above-described scroll type fluid machine, the projecting wall 23 of the frame 2 has a size that includes the finishing locus L of the keyway 24, and the depth from the mounting surface 22 is the same as that of the projecting wall 23 of the frame 2. Since the taped portion 25 is formed with a depth that almost matches the support surface 21, by forming the taped portion 25 prior to grooving along the finishing trajectory L, the height of the key groove 24 is increased. This makes it possible to finish with precision.

くできるのである。 Furthermore, when cutting the key groove 24 using an end mill or the like, since the cut portion 25 is formed in advance, it is only necessary to cut the key groove 24 to the same depth from the inner circumferential side to the outer circumferential side of the frame 2. Therefore, the resistance of the end mill during the cutting process is reduced, the key groove 24 can be accurately formed without chatter occurring in the end mill, and the life of the end mill can be extended.
