Title:
CONNECTING ROD OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2019143662
Kind Code:
A
Abstract:
To provide a connecting rod of an internal combustion engine capable of preventing a pressure from locally concentrating on an inner peripheral face of a hole to which a crank shaft is inserted.SOLUTION: A connecting rod for connecting a first end portion and a second end portion, includes a wide portion 32 of which a width orthogonal to both of a longitudinal direction and a thickness direction from a column portion 20 extended in the longitudinal direction orthogonal to the thickness direction, is gradually expanded, a wide width central portion 32a overlapped to a line segment orthogonal to a central axis of the connecting rod connecting the first end portion and the second end portion, and a pair of wide width outer edge portions 32b holding the wide width central portion from a width direction. The column portion includes a column central portion 20a and a column outer edge portion 20b, each of the pair of wide width outer edge portions has a thickness thicker than the wide width central portion, each of the pair of column outer edge portions has a thickness thicker than the column central portion, a ratio of a cross-sectional area orthogonal to the line segment of the wide width central portion, to a unit area orthogonal to the line segment is smaller than a ratio of a cross-sectional area orthogonal to the line segment of the column central portion to the unit area.SELECTED DRAWING: Figure 2
