摘要： A joint mechanism for a mowing machine which can be easily assembled and disassembled, including a support member of a casing which houses a cylindrical damper, which prevents vibration of a power unit from being transmitted to a rod, a holder in which the rod is inserted, and a clamp, which clamp prevents the damper and the holder from unintentionally separating from the support member, being inserted therein. The clamp has a flexible arm which extends in the direction of an output shaft of a power unit, and an engagement hook is formed on the tip of the arm. An engagement hole which the engagement hook of the clamp engages is provided on the support member.

摘要： An engine including first scavenging passages for fluidly connecting between a combustion chamber and a crank chamber through bearings for the crankshaft, second scavenging passages fluidly connecting directly between the combustion chamber and the crank chamber, a suction chamber formed in a side face of a piston. An air-fuel mixture is sucked into the suction chamber and an air is introduced into the crank chamber. During the intake stroke, the air-fuel mixture from the air-fuel mixture passage is introduced into the first scavenging passages through the suction chambers, and the air is introduced into the crank chamber. During the scavenging stroke, before the air-fuel mixture in the first scavenging passages is introduced into the combustion chamber, introduction of the air in the crank chamber into the combustion chamber through the second scavenging passages starts.

摘要： A muffler for small general-purpose engine includes a case comprising a pair of case halves coupled together and divided into a first chamber and a second chamber by a partition plate. An inlet of the exhaust gas is provided closer to a first end portion of the case in a first case half. An outlet of the exhaust gas is provided closer to a second end portion of the case in a second case half. A recess projecting from the first chamber toward the second chamber guiding the exhaust gas from the inlet toward the second end portion is provided in the partition plate opposite the inlet. A communication orifice is formed in the partition plate at a location offset from the recess and closer to the first end portion than the inlet.
