In recent years, internal combustion engines are increasingly being operated at high speeds, and with this high speed operation, there is a need to reduce the weight of reciprocating parts such as connecting rods in order to reduce vibration and noise. ing. Recently, for this purpose, lightweight materials such as aluminum alloy and magnesium alloy have been used instead of conventional steel to reduce the weight.

However, this type of lightweight material has lower strength than steel, and the strength decreases even more at high temperatures, so the wall thickness must be increased, and the drawback is that it is not necessarily possible to reduce the weight by the same amount as the difference in specific gravity. In view of the above points, the present invention was made with the aim of reducing the weight of the connecting rod material by reinforcing it with reinforcing fibers. By skillfully arranging the connecting rod to effectively support the load caused by the explosive force and inertial force of the rod, the strength of the connecting rod was further increased, making it possible to make it even lighter.

The present invention has the above arrangement, and thus, in the present invention, at least the connecting rod stem portion is formed by a fiber-reinforced stem column and a stem plate,
These fiber arrangements are configured to effectively receive the compressive load due to explosive force and the tensile load due to inertial force, respectively, so the strength against these loads is high, and the stem portion is therefore stronger than conventional ones. It was possible to reduce the weight by reducing the size of the . In particular, according to the present invention, since the end of the stem plate that receives a tensile load is placed and supported under pressure on the large end upper surface member, which is another member, the end of the stem plate that receives a tensile load is supported under pressure. This has the effect of preventing the stem plate from coming off.
