摘要： A silencer includes conduit with a downstream end portion configured from a tubular member which includes a conduit discharge port extending through a silencer main body and discharges exhaust gas to the outside therethrough. The tubular member includes a resonance communication hole communicating with a resonance chamber and an upstream side communication hole and a downstream side communication hole communicating with a second chamber. A barrier wall serving as a throttle portion for throttling an exhaust path at an intermediate location of the tubular member is provided in the inside of the tubular member and between the upstream side communication hole and the downstream side communication hole.

摘要： A vehicle exhaust system structure capable of easily improving output performance in comparison with a two-cylinder internal combustion engine having the same displacement and outputting an appealing and excellent exhaust sound relating to the two-cylinder internal combustion engine, in a four-cylinder internal combustion engine or a three-cylinder internal combustion engine. An exhaust pipe structure for an internal combustion engine is configured such that exhaust pipes are respectively connected to four cylinders of a four-cylinder internal combustion engine, the two exhaust pipes of the exhaust pipes are formed as long exhaust pipes having a long pipe length while the other two exhaust pipes thereof are formed as short exhaust pipes having a short pipe length, and a difference in a pipe length between the long exhaust pipes and the short exhaust pipes is set to 150 mm or more.

摘要： A variable-speed drive device for a power unit to be used in a vehicle equipped with a stopper pin passed through an opening in a master arm for regulating the amount of rotary movement of the master arm. Shock-absorbing device is provided on the master arm or the stopper pin At least a part of the shock-absorbing device is formed to project into the path along which the stopper pin moves relative to the opening of the master arm, from a stopper pin outer surface or from edge portions of a defining edge of the opening in the master arm onto extension of the stopper pin path. As a result, even if the master arm and the stopper pin contact one another at high speed, it is possible to suppress the sound of contact and suppress an increase in the weight of a stopper pin fixing part.

摘要： A transmission for a vehicle has a main shaft and a counter shaft, which are supported in a transmission case by bearings. Gears on the main shaft and gears on the counter shaft include: shifter gears which are not rotatable but axially movable relative to the shaft, and fixed gears which are rotatable but not axially movable relative to the shaft. Dog clutches are provided between the shifter gears and the fixed gears, and outer races of the bearings supporting the main and counter shafts are affixed to the transmission case. Vibration-absorbing elastic members are pressed against the outer races from axially outside and are set to have a volume of 50% or more of the volume of the outer races. With such configuration, the vibration of the bearings supporting both the main and counter shafts of the transmission is attenuated, and striking noise caused by shifting is reduced.
