Since the grooves 5 are formed by etching, the roller 14
The plastic material 4 makes contact between the tip that is in contact with the sliding surface that slides in the guide groove 15 of the cylinder 12, preventing metal-to-metal contact, and furthermore, the lubricating oil 1 is injected into the etched groove 5. The accumulating wear resistance is significantly improved, and there is no decrease in mechanical strength or heat dissipation due to the foamed metal 2.

。As described above, the present invention provides a mechanical part constructed by using foamed metal as an aggregate and filling the bubbles of the metal with a heat-resistant and wear-resistant plastic material, in which the foamed metal exposed on the surface of the mechanical part is treated with a dissolving agent. Since the grooves are formed by etching, the foamed metal improves the heat dissipation and mechanical strength that are the characteristics of metal without sacrificing the ease of molding and accuracy of processing that can be achieved by integrally molding the plastic material. Since contact with other parts is made only through the plastic material, there is no metal-to-metal contact, and if the etched grooves are used as lubricating oil reservoirs, the wear resistance is significantly improved, making it a mechanical part that is useful in practical terms. We can provide manufacturing methods.
