摘要： PROBLEM TO BE SOLVED: To reduce the number of components for a cover and man-hours for installation while assembling a connecting rod and a plunger on a crank shaft outside a crank case by separating a crank case in a cross section including each axial core of the crank journals of the crank shaft and a plunger. SOLUTION: A ball bearing 6 and the like are arranged on a start end side crank journal 2a and a final end side crank journal, and a V-shaped packing 7 is arranged around a plunger 5. Bolt fit-in grooves 1d, 1d of reinforcing bolts 9, 9 are recessed on both overlapping surfaces of an upper case 1U and a lower case 1D in order to oppose to twist stress by crank motion. Each head part of the reinforcing bolt 9 is fit to each bolt fitting-in groove 1d of the separated lower case 1D (the upper case 1U), the lower case 1D is covered with the upper case 1U, and both cases 1U and 1D are fastened with each other. It is thus possible to assemble one end of the reinforcing bolt 9 with a crank case 1.
