  "textContent": "Object: In a piston cooling structure for a multicylinder engine having oil jets for ejecting oil toward pistons, mounted in those of a plurality of journal walls except one journal wall, by which a crankshaft is rotatably supported, to be able to supply oil to a cylinder head in a position closer to a central region along the axis of the crankshaft while avoiding a complex oil passage shape. Solving Means: An oil passage (65) for guiding oil to a cylinder head is defined in one of journal walls (22B, 22C, and 22D) disposed between pairs of adjacent ones of the cylinder bores (20), of all journal walls (22A through 22E), and oil jets (64) are mounted in the journal walls except the journal wall with the oil passage (65) defined therein.",
