Abstract: A device with an adjustment bolt includes a bolt attachment wall, an adjustment bolt screwed with an internal thread hole of the bolt attachment wall, a locknut screwed with the adjustment bolt, a cover that surrounds the adjustment bolt and the locknut, and a stopper unit that prevents removal of the cover from the locknut. The stopper unit includes an inner circumference groove of the cover fitted around a C-shaped retaining ring, and an external circumference groove of the locknut fitting within the retaining ring. The external circumference groove includes a first groove portion having a large-diameter groove bottom that restricts contraction and removal of the retaining ring fitted within the inner circumference groove, and a second groove portion provided continuously for the first groove portion and having a small-diameter groove bottom that allows contraction and removal of the retaining ring fitted within the inner circumference groove.

Abstract: There is provided an engine water-cooling device that can increase warming-up efficiency of an engine. The engine water-cooling device includes a thermostat housing that houses a thermostat. The thermostat housing is mounted to a front wall of a cylinder head in one side portion in a width direction of the cylinder head. A cooling water pump is mounted to a front wall of a cylinder block in a central portion in a width direction of the cylinder block. A bypass passage includes an intra-head bypass passage in the cylinder head, and the intra-head bypass passage includes a width-direction passage portion extending from a position behind the thermostat housing to a position behind and above the cooling water pump.
