  "textContent": "A first water jacket (12) has a plurality of first cooling water inlet portions (16) in its central region, and has two first cooling water outlet portions (17) in one lateral surface side of a cylinder head to which an exhaust component is attached. The first cooling water outlet portions (17) are such that the spacing between those located on either side in a cylinder row direction is wider than a spacing between the first cooling water inlet portions (16) located on either side in the cylinder row direction. First female threaded portions (19) protrude into the first water jacket (12) and are disposed so as to be located inside the two first cooling water outlet portions (17) in the cylinder row direction. Bulging portions (21) which extend from the ends of the first female threaded portions (19) towards the side where the first cooling water inlet portions (16) are located are disposed so as to protrude into the first water jacket (12) in a cylinder head (11).",
