ンププレート１１部分で発生する騒音を抑える。 Since an internal combustion engine is used as the drive source for the drive shaft 1, the explosion causes rotational fluctuations in the drive shaft, which is transmitted to the weight roller 15, which vibrates within the end 14 and hits the lamp plate 11. However, since the first bent part 19a of the seal rubber 17 is in contact with the lamp plate 11, the vibration of the lamp plate 11 is suppressed, and the second bent part 19b, as shown in FIG.
Since it is also in contact with the freewheel 20, which can also be a source of noise, the effect is doubled.
During high-speed rotation, the movable pulley half 5 moves to the left as shown in FIG. 2, so the first bent portion 19a is further pressed against the lamp plate 11, suppressing noise generated in this portion of the lamp plate 11.

振の可能性のある機能部品であればよい。 Note that the seal rubber 17 has a core material 24 as shown in the figure.
When inserted, the contact force will be improved and the effect will be even more effective. Further, in the above embodiment, the second bent portion 19b is in contact with the freewheel 20, but the second bent portion 19b is not limited to this, and may be any functional component that is adjacent to the lamp plate and has a possibility of resonance.
