PURPOSE:To contrive to make the titled engine compact by reducing a space, by molding a cowling of a miniature engine of a scooter and an air cleaner casing unitarily. CONSTITUTION:A cover 6 incorporating a crankcase 7, an engine body 1 and a crankshaft 4 is made of synthetic resin, which is a part molding a cowling part 8 and an air cleaner casing part 9 in a body. Then, a gap to be generated between two parts as usual can be omitted and compactness of a titled engine is contrived. A weight reduction of the titled engine is contrived as the unified cover 6 is made of synthetic resin. |
