<p>Bending of a lubricant branch pipe can be reduced as much as possible, the pipe length of the lubricant branch pipe can be reduced as much as possible, and pressure loss of the lubricant that flows in the lubricant branch pipe can be reduced. A central axis of a first oil channel (15), which passes through a main-bearing cap (9) in a plate-thickness direction thereof, and a central axis of a second oil channel (16), which passes through a base-plate saddle (12) in a plate-thickness direction thereof, intersect at 0 degree to 45 degrees; a central axis at one end of a lubricant branch pipe (20), which is connected to an inlet portion of the second oil channel (16), and a central axis of the lubricant branch pipe (20) excluding the one end also intersect at 0 degree to 45 degrees; and the lubricant branch pipe (20), excluding one end thereof, extends in a straight line in the widthwise direction of the base plate.</p> |
