う問題が生ずる。(Prior Art) The inventor of the present application proposed a rotor consisting of a hollow main body, both side plates welded to both sides of the main body, and a rotating shaft provided on one or both of the both side plates (Japanese Patent Application No. 58 −28611). Although the weight of the rotary fluid pump has been reduced to a certain extent by the proposed rotor, in order to further reduce the weight, the rotating shaft and both side plates must be made of a light alloy such as aluminum. However, if the rotating shaft and the like are made of light alloy, the problem arises that the strength becomes weak and it cannot be used.

とする。 Composite material is made by placing a whisker molded body press-molded to a maximum porosity of about 50% into a mold with a rotating shaft.
Molten base metal is injected into the mold to infiltrate into the voids of the whisker molded body. Next, the rotating shaft of the forged composite material is fixed to the side plate, and the side plate is welded to the rotor body to form a hollow rotor body.

As shown in FIGS. 1 and 2, a rotor body 12 of the rotor 10 is formed in a hollow shape, and side plates 13 and 14 formed by press molding or forging are welded to both sides of the rotor body. The rotating shafts 11 and 15 of the whisker-type composite material are connected to the side plates 13,
It is forged integrally with the side plates 14 or manufactured separately and welded to the side plates 13 and 14.

する。 As shown in FIGS. 3 and 4, both side plates 13 and 14, which are integral with the rotating shafts 11 and 15 on both sides, are made of whiskers F made of inorganic materials such as silicon carbide, carbon, and glass, and iron-based materials such as steel. Alternatively, it is a composite material made of a base metal M of a light metal material such as aluminum, an aluminum alloy, or a magnesium alloy. The whiskers are pressure-formed to have a porosity of at least 50% and placed in a mold for forging both side plates 13, 14 integral with the rotating shafts 11, 15 on both sides. A molten metal of the base material light metal M is injected into the mold and infiltrated into the voids of the whiskers F, and the rotating shaft 1 on both sides of the composite material consisting of the whiskers F and the base material light metal M is injected into the mold.
Both side plates 13 and 14 are manufactured integrally with 1 and 15. Both side plates 1 integrated with rotating shafts 11 and 15 on both sides
In Nos. 3 and 14, the base metal M is reinforced with whiskers F, which are ultra-high strength fibers, so the weight is very light but the strength is high. The thus manufactured side plates 13 and 14 integral with the rotating shafts 11 and 15 on both sides are forged and then welded to a separately manufactured rotor body to form a rotor.

する。 The whiskers are pressurized so that a maximum porosity of about 50% remains and are placed in a forging mold, into which molten base metal is injected. As shown in FIG. 3, the molten metal is infiltrated into the gaps of the whiskers and becomes a material for forging both side plates 13 and 14 which are integral with the rotating shafts 11 and 15 on both sides, and this material is then forged to form a hollow rotor. The side plates 13 and 14, which are manufactured by forging and are integral with the rotating shafts 11 and 15 on both sides, are
As shown in the figure, whiskers F in the base material light metal M
are aligned along the grain flow line, so the rotation axes 11, 1
