Abstract

PURPOSE:To enable to assemble and machine coupling parts with ease, by making the top of an inner wall of a cylinder block to which a cylinder head is fixed higher than the top of an outer wall to which a heat cover is fixed. CONSTITUTION:A cylinder 5 consists of an inner wall 8 formed with a cylinder bore 7 and an outer wall 9 surrounding the inner wall 8 and forming a water jacket 10a. A cylinder head 12 is screwed to the top of the inner wall 8 and a boss part 12a at the central part of the cylinder head 12 to which an ignition plug is fixed is fitted into a hole 16 formed at the central part of a head cover 15. Further, a nut 17 is threaded onto the boss part 12a so that the head cover 15 is fixed tightly to the top of the outer wall 9. Here, since the top of the inner wall 8 is made higher than the top of the outer wall 9, assembling and machining of the coupling parts is not hindered by the outer wall 9.
