2個所で取付けられている。First, in the exhaust gas (not shown) provided in the cylinder head 1 of the small two-cylinder internal combustion engine shown in FIG.
As shown in the figure, there are independent exhaust passages 2A and 2B, respectively.
An exhaust silencer 3 is connected to the exhaust silencer 3, and the seven rungs 4A and 4B at the ends of the exhaust passages 2A and 2B are attached to the cylinder head 1 at two locations with bolts 5. .
