Field of the Invention The present invention is formed between a pair of scroll members by relatively orbiting a pair of scroll members in a state where the scroll members are superposed with the phases thereof shifted from each other. The present invention relates to a scroll compressor that reduces the volume of a closed space and compresses a fluid in the closed space, and a manufacturing method thereof.

し易かった。2. Description of the Related Art A scroll type compressor has been widely used in the past, in which a pair of scroll members having the same shape are combined with each other and one scroll member is revolved to compress a fluid. Each scroll member that constitutes this type of scroll compressor is provided with a side plate and a spiral body integrally in order to ensure a desired mechanical strength. Is a cantilever that acts on
In particular, a large stress was applied to the root portion of the inner end portion, and it was easily damaged.

れている。Therefore, as disclosed in Japanese Utility Model Publication No. 1-28315, a rib having a cross-sectional area on the root side larger than that on the upper side is provided at the terminal end of the scroll member of the scroll member. A scroll compressor is known in which the rib is configured to extend in a direction along the spiral curve of the spiral body.

エンドミルの寿命が短いという問題が指摘されている。However, since the scroll member is a cast or forged material, a draft is provided to ensure releasability. For this reason, the machining allowance on the base side is large, and a large load particularly acts on the tip of the end mill. Moreover, it is difficult to increase the diameter of the end mill due to the limitation of the width between the spirals, and as the spiral height increases, each end mill becomes elongated and its rigidity decreases. As a result, it has been pointed out that chipping easily occurs at the tip of the end mill during rough machining, and the life of the end mill is short.

る。In order to solve the above-mentioned problems, according to the present invention, a scroll member is machined by a chamfered part of an end mill having a relationship of height / width> 1, so that the height on the spiral body side is increased. A reinforcing portion having a relationship of depth direction / side plate side width direction> 1 is provided at the root of the inner end of the spiral body. Therefore, the chamfered portion becomes larger than that of an end mill having a single radius (R) tip, the load on the tip of the end mill is reduced particularly during rough machining, and chipping of the tip of the end mill is reliably prevented. be able to.
