Title:
CONNECTING ROD
Document Type and Number:
Japanese Patent JP2016211648
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a connecting rod which can suppress the generation of seizure at a small end part.SOLUTION: In this connecting rod 13, protrusions 28 which protrude to an elongation direction of a center axis C are formed at both end parts of the center axis C at a small end part 15 in an elongation direction so that a length in the elongation direction of the center axis C of the pin hole 19 of an internal peripheral face 30 at which the pin hole 19 at the small end part 15 is formed becomes long as progressing toward a large-end part side. Then, in the connecting rod 13, the surface roughness of a portion 30a out of the internal peripheral face 30 which is formed of the protrusions 28 is finer than the surface roughness of a portion 30b out of the internal peripheral face 30 which is formed of a center part 29 located between the protrusions 28, 28 in the elongation direction of the center axis C.SELECTED DRAWING: Figure 4
