。 An annular outer groove into which a lubricating oil supply passage from a lubricating oil source opens is formed on the inner circumferential surface of the bearing hole into which the bearing metal for the journal portion of the crankshaft fits. Each of the inner circumferential grooves is provided, and a lubricating oil passage is bored in the crankshaft that communicates the outer circumferential surface of the journal portion with the outer circumferential surface of the crank pin portion, and further, the outer groove and the narrow inner circumferential groove are provided. In a lubricating device configured such that the lubricating oil supply passage communicates with a large diameter through hole having an inner diameter substantially the same as that of the lubricating oil supply passage at a portion where the lubricating oil supply passage opens into the outer groove, the bearing metal has the thin A plurality of small diameter through holes having an inner diameter equal to or smaller than the width of the inner circumferential groove are provided so as to communicate the outer groove with the narrow inner circumferential groove at a plurality of locations other than the large diameter through hole. A unique crankshaft lubrication device for internal combustion engines.
