PURPOSE:To simplify machining and to prevent a lowering of strength by fastening a rod portion forming the half split portion of a large end portion bearing and a cap portion forming the other half split portion of the large end portion with a U-shaped bolt. CONSTITUTION:The bent portions of U-shaped bolts 13a, 13b are fitted parallel to shoulder portions 10a, 10b disposed on the outer wall of the half split portion of the large end portion bearing of a rod portion 9 to be retained in contact therewith. Both side portions of the U-shaped bolts 13a, 13b are inserted in bolt insertion holes 13a-13d of a cap portion 11 formed as the other half split portion of the large end portion, and nuts 14a-14d are engaged with the forward screw portions of the U-shaped bolts 13a, 13b projected out from these insertion holes and tightened, so that the cap portion 11 is pressed to the large end portion of the rod portion 9 to be fixed thereto. |
