費等のエンジン性能が大きく改善される。A large inertial force acts on the connecting rod of an internal combustion engine due to the piston, the piston pin, and the front of the connecting rod itself. Reducing these inertial masses greatly contributes to improving engine responsiveness, output, and operating costs. Therefore, if the connecting rod is made of carbon fiber-reinforced aluminum or magnesium alloy reinforced with carbon, alumina, and steel thread, the amount of ``J1'' of the connecting rod will be significantly higher than that of steel thread.
This greatly improves engine performance such as engine response and engine fuel efficiency.

７を心裏とする。Connecting rods made of fiber-reinforced resin or fiber-reinforced metal of Japanese cypress have been known for a long time, and conventional connecting rods have unidirectional long fibers oriented in the main body, small end, and large end. That is, as shown in FIGS. 4 and 5, at the small end 1 and large end 2 of the connecting rod, along the circumference of the small end hole 1a and the large end hole 2a, respectively,
In addition, long fibers 4 are oriented along the length of the four-body portion 3 that connects the small end portion 1 and the large end portion 2. Since the fiber-reinforced resin or gold has a large strength in the longitudinal direction of the polar axis, such a conventional connecting rod has sufficient strength in its main body against 6.7 blood pressure due to explosive force and inertial force. On the other hand, at the small end 1 and the large end 2, the holes 1a,
