PROBLEM TO BE SOLVED: To provide a crankshaft capable of transmitting relatively large torque with a simple, cost-saving means while avoiding defects caused by a conventional arrangement. SOLUTION: The crankshaft comprises: a means for connecting a front range of a connecting strut 5 with a rear range of the connecting strut by looking through an inserting direction; a means for forming a tapered conical body 9 by looking through the inserting direction; and a means for mounting a stop ring 10 so as to prevent axial movement of the connecting strut along its axial direction against a crank web 1. The conical body is continued to the rear range of the connecting strut in the crankshaft, and therefore, both the connecting strut and a crank web hole corresponding to the connecting strut are not necessary to adjust their sizes step by step. Contracting combination can be surely guaranteed along the full length of the connecting strut without fear of any gap between them. An average diameter of the conical body is basically greater than the diameter at an edge of the front portion, and it becomes one of advantages regarding attainable transmitting torque.
