Abstract

The invention is to provide an engine which can fully ensure the heat dissipation of the cylinder head, and make ease the replacement of the plug and the maintenance of the cylinder cover. First and second head covers 75, 76 are attached to a cylinder head 30 in which an intake/exhaust port is formed so that an engine 27 is made to look like large, and the upper part of a camshaft storage part 36 is covered with these head covers 75, 76. At this time, the head covers 75, 76 are arranged by being separated from each other, an opening part 98 opened to the front, upper and rear parts of the cylinder head 30, is formed, and a space among the cylinder head 30 and the head covers 75, 76 is opened to the atmosphere by this opening part 98. Also, an extended part 77 extended downward is formed in the bottom wall of the head cover 76, a plug lead-through opening is formed in the position of this extended part 77, where is opposite to an ignition plug 39, and cooling fins 79, are integrally formed on the peripheral surface of the extended part 77.
