Abstract

Un acoplamiento (13) inferior se forma de tal manera que los lados circunferenciales exteriores de ambas porciones extremas de un agujero (21) pasante de muñequilla son más rígidos que una porción central del agujero (21) pasante de muñequilla, es decir, una porción de bifurcación de una forma bifurcada del mismo. Dichas ambas porciones extremas del agujero (21) pasante de muñequilla se forman de tal manera que las superficies (22a) circunferenciales interiores de las dos porciones extremas se curvan en una curvatura predeterminada en una dirección axial de un cigüeñal sin una entrada de carga sobre el acoplamiento (13) inferior. Además, la porción central del agujero (21) pasante de muñequilla se forma de tal manera que una superficie (22b) circunferencial interior del mismo se localiza hacia el interior de las superficies (22a) circunferenciales interiores de dichas ambas porciones extremas y es recta en la dirección axial del cigüeñal sin una entrada de carga sobre el acoplamiento (13) inferior.
