Abstract

PURPOSE:To enable lubrication of a main bearing even when revolutions are lowered by forming an oil passage on a crank, which is inclined in such a way that the opening position of the axial section of a rotating shaft on the side of a hollow section is low while the opening position on the side of an outer circumference is high. CONSTITUTION:A crank 4 formed eccentrically and monolithically on the part of a rotating shaft 5 is formed with an oil passage 18 in such a way as to let the opening on the side of an axial section 17 be low wherein the passage communicates the axial section 17 with a slit shaped oil groove 21 formed on the outer circumference at the opposite side to the eccentric side of the crank 4. Owing to this constitution, when the revolution of the rotating shaft 5 is lowered with an oil level 32 lowered, lubricant 20 in the oil passage 18 is subjected to centrifugal force so as to be fed to an annulus ring groove 25 through the slit shaped oil groove 21 of the crank 4, from which feed is continued to a main bearing 9 by way of an oil groove in a spiral form 23, thereby enabling lubricant to be fed to the main bearing 9 even when the oil level is lowered.
