<P>PROBLEM TO BE SOLVED: To provide an inexpensively manufacturable connecting rod with superior positioning and load resistance in an abutting position of a rod body and a cap. <P>SOLUTION: In the connecting rod 1, the rod body 2 an the cap 3 abut on each other at two places, and they are fastened by bolts. In the abutting position of the two places, joint surfaces 2a, 2b of the rod body 2 and joint surfaces 3a, 3b of the cap 3 abut on each other. The joint surfaces 2a, 3b are recessed and conical becoming narrower toward bottom sides, and the joint surfaces 2b, 3a are protruded and conical becoming slimmer toward a vertex side. The recessed and protruding joint surfaces 2a, 2b, 3a, 3b fit together, and bolt holes 2c, 2d, 3c, 3d are formed in the joint surfaces 2a, 2b, 3a, 3b. <P>COPYRIGHT: (C)2009,JPO&INPIT |
