Zusammenfassung:	PROBLEM TO BE SOLVED: To easily form a through-hole in a crank weight. SOLUTION: In this crankshaft 60 in which a crank main shaft 50 and a crank pin 11 for connecting among crank webs 1 arranged in parallel in the axial direction of the crank main shaft 50 and a pair of adjacent crank webs are integrally formed, through-holes 41a, 41b and through-holes 42a, 42b are formed in the first crank weight 21 and the second crank weight 22, respectively, and the through-holes 41a and 42a and the through-holes 41b and 42b are formed on axial lines L2, L3 extending substantially in parallel with the crank main shaft 50 each. The through-holes 41a and 41b are formed to be larger than the through holes 42a and 42b. The through-holes 41a, 42a, 43a, 44a are formed on the axial line L2, and the through-holes 41b, 42b, 43b, 44b are formed on the axial line L3. COPYRIGHT: (C)2007,JPO&INPIT
