2. Description of the Related Art In a resin molded product obtained by casting a metal part, it is difficult to secure the bonding strength between the resin part and the metal part, and the bonding interface peels off, and moisture enters the interface to promote corrosion. I am worried. As a means for increasing the bonding strength, it is common to provide an undercut-shaped stopper for the metal component. The retainer protruding from the metal part bites into the resin part, and has a certain effect in securing the bonding strength between the resin part and the metal part. Simply providing the undercut-shaped stopper on the metal component cannot improve the adhesion between the resin portion and the interface of the metal component. Therefore, it has been proposed to perform a physical or chemical roughening treatment on the surface of the metal component, but the improvement in adhesion is insufficient for the required man-hour and cost.

A resin molded product in which a metal part and a reinforcing fiber base are arranged in a molding die, a liquid resin is injected into the molding die, the reinforcing fiber base is impregnated, and the metal part is cast and molded. In the manufacture (injection molding) of the above, it is particularly important to secure the adhesion between the resin portion and the interface of the metal component. The reason is as follows. In the injection molding, the reinforcing fiber base is deformed by the pressure when the molding die is closed, so that the retaining protrusion protruding from the metal component is cut into the reinforcing fiber base. In this state, when the liquid resin is injected into the molding die, the resin portion including the reinforcing fiber base and the metal component are bonded. At the time of injecting and curing the liquid resin, the reinforcing fiber base material is hardly deformed and the biting is hardly promoted. This point is significantly different from the production of a resin molded product in which a reinforcing fiber base material previously impregnated with a resin is heated and pressed and a metal component is cast and molded. That is, in the heat-press molding, the reinforcing fiber base is deformed with the flow of the resin and is filled around the retaining fiber, so that the resin portion including the reinforcing fiber base and the metal component are securely bonded. On the other hand, in the injection molding, since the deformation of the reinforcing fiber base due to the flow of the resin hardly occurs, the filling of the reinforcing fiber base around the retaining member tends to be insufficient. Therefore,
In a resin molded product obtained by injection molding, it is important to secure adhesion between the resin portion and the metal component interface in order to improve the bonding strength in order to compensate for insufficient filling of the reinforcing fiber base around the retaining member.

A metal component is cast and formed by impregnating a reinforcing fiber base material. The feature is that the metal part is made of a sintered alloy, and the liquid resin penetrates from the surface of the metal part into the microporous surface of the metal part and is hardened. The porosity of the metal component surface is preferably 0.1 to 0.2. Here, the porosity is determined by the following equation.

## EQU1 ## 1- (specific gravity of metal part / specific gravity of porosity metal part) As described above, the filling of the reinforcing fiber base material around the metal part in the injection molding is performed when the molding die is closed. The deformation is performed by the deformation of the reinforcing fiber base material under the pressure described above.
In this state, when the liquid resin is injected into the molding die, the resin portion including the reinforcing fiber base and the metal component are bonded.
In the present invention, in addition, since the liquid resin penetrates into the microporous surface of the metal component and is hardened, the adhesion between the resin portion and the metal component is significantly improved. This contributes to an increase in bonding strength between the resin part and the metal part. In particular,
Since there are fine and deep porosity on the surface of the metal component made of the sintered alloy, the liquid resin penetrates to the deep portion to increase the bonding strength. Even if a metal part surface is subjected to physical treatment such as shot blasting or chemical treatment such as oxidation to impart irregularities, the former is rough because the former is rough and the latter is shallow, so the present invention is expected. No effect can be obtained. In a resin molded product obtained by injection molding, a remarkable function and effect can be obtained for the first time by employing a sintered alloy as a metal component and employing the configuration according to the present invention.

The manufacture of such a resin molded product is performed as follows. A metal part and a reinforcing fiber base are arranged in a molding die, a liquid resin is injected into the molding die, the reinforcing fiber base is impregnated, and the metal part is cast and molded. The liquid resin injected into the molding die is made to permeate into the microporous from the surface of the metal component by using the method. Preferably, the liquid resin is injected after the pressure in the molding die is reduced. However, if the porosity of the surface of the metal part is increased, the liquid resin can be permeated into the microporous without necessarily reducing the pressure.

FIG. 1 is a partially cutaway perspective view of a gear resin molded product in which a ring body 2 is stacked in two stages in a molding die, and a metal part 3 (bushing) is arranged in the center and integrally molded. ing. The ring body 2 is compressed and deformed by the pressure at the time of closing the molding die, conforms to the shape of the metal component 3, the pressure inside the molding die is reduced, and a liquid resin (crosslinked polyaminoamide, epoxy resin, polyimide, etc.) is injected. And heat-cured. The retaining member 4 provided on the metal part 3 bites into the ring body 2, and the ring body 2 and the metal part 3 are integrated. Further, as shown in the enlarged view of FIG. 2, at the interface between the resin portion 5 including the ring body 1 and the metal part 3, the resin impregnated in the ring body 2 has a deep fine surface of the metal part formed during sintering. It has penetrated the pores and is hardened. The action of the retaining member 4 biting into the ring body 2 and the sufficient penetration of the resin into the micropores are combined to realize a large joining strength between the resin portion and the metal component. Further, since the bonding strength is large, a gap is hardly generated at the interface between the resin part and the metal component. Therefore, it becomes difficult for moisture and the like to enter this interface from the outside,
Generation of resin cracks and the like due to internal rust can also be suppressed. The gear is completed by forming teeth around the formed ring body 2 by cutting.

[0010] Although a sufficiently deep microporosity is formed on the surface of a metal part made of a sintered alloy, the surface of the metal part can be further blasted or oxidized if both are used together. Microporosity will take on complex shapes. Fine gaps are more difficult to be formed at the interface between the resin part and the metal component, which is preferable in preventing moisture and the like from entering the interface. It is also preferable that the surface of the metal component is cleaned or heated and degreased before molding.
