Beschreibung
Zusammenfassung:	A crankshaft includes journals (J) serving as a central axis of rotation, crank pins (P) decentered from the journals (J), and crank arms (A) connecting the journals (J) and the crank pins (P). Some or all of the crank arms (A) have counterweights integrated therewith. At least one of the crank arms (A) has a recess (10) in a crank pin (P)-facing surface. The crank arm (A) includes ribs (11) formed respectively in two side portions of the recess (10) along a periphery of the crank arm (A).
