この曲げ振動に伴うフライホイールの面振れを制
振するダンパであつて、上記フライホイールの円
周に沿つて該フライホイールの面部に形成された
環状の溝内にフライホイール側とは非接触状態で
配設される環状若しくは円弧状の慣性体と、該慣
性体がフライホイールの面振れ方向若しくは遠心
方向に振動し得るように慣性体とフライホイール
とを弾性結合する弾性部材とを備え、上記クラン
ク軸の曲げ振動発生時に上記フライホイールに直
接作用してフライホイールの面振れ及びクランク
軸の曲げ振動を制振するフライホイールダンパ。 A damper that suppresses bending vibrations generated in the crankshaft of an engine and surface runout of a flywheel accompanying the bending vibrations, the damper having an annular groove formed in the surface portion of the flywheel along the circumference of the flywheel. an annular or arc-shaped inertial body disposed in a non-contact state with the flywheel side, and a structure in which the inertial body and the flywheel are connected so that the inertial body can vibrate in the plane runout direction of the flywheel or in the centrifugal direction. and an elastic member that is elastically coupled to each other, the flywheel damper acts directly on the flywheel to suppress surface runout of the flywheel and bending vibration of the crankshaft when bending vibration of the crankshaft occurs.
