<P>PROBLEM TO BE SOLVED: To reduce gear meshing noise due to driving torque between a crankshaft and an eccentric shaft and gear rattling noise generated by torque inversion. <P>SOLUTION: The crankshaft 12 includes coaxially a timing gear 63, the eccentric shaft 66 includes an eccentric gear 65 which is meshed with the timing gear 63 and to which the rotation of the timing gear 63 is transmitted, and a cylinder barrel 16 includes a lubricating oil channel 102 which supplies lubricating oil to a shaft end (lower shaft end) 12c of the crankshaft 12 and the shaft end (lower shaft end) 66c of the eccentric shaft 66, and an injection part 103 which is installed on the lubricating oil channel 102 and injects the lubricating oil towards the meshing part 104 between the timing gear 63 and the eccentric gear 65. <P>COPYRIGHT: (C)2012,JPO&INPIT |
