  • CONNECTING ROD STRUCTURE OF ENGINE
    Publication number: 20150240711
    Abstract: A connecting rod structure includes a connecting rod for coupling a crankshaft to a piston, the connecting rod including a larger end part formed with a shaft insertion hole for the crankshaft, a smaller end part formed with a pin insertion hole for a piston pin which couples the piston to the smaller end part, and a coupling part for coupling the larger end part to the smaller end part; and a dynamic absorber provided to the larger end part for suppressing the piston, the piston pin, and the connecting rod from integrally resonating with respect to the crankshaft. The dynamic absorber includes a fixed part fixed to the larger end part and a supporting part for coupling the fixed part to a mass part and supporting the mass part to be movable in substantially longitudinal directions of the connecting rod with respect to the fixed part.
