【考案の詳細な説明】
本考案はトーシヨナルダンパ装置に関し、主と

のに好適なものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a torsional damper device, and is suitable for use primarily by being mounted on the end of a crankshaft of an automobile engine.

つた悪循還が生じ、このためラバーの歪率および
温度が過大となり、耐久性に支障を来たすといつ
た不具合があつた。 Conventionally, in a torsional damper device mounted on the end of a crankshaft, if the device is used for a long time at the resonance point of torsional vibration, the temperature of the rubber increases, causing viscous damping, which in turn causes an increase in the resonance amplitude. Increasing the temperature of the rubber causes a vicious cycle, which causes the strain rate and temperature of the rubber to become excessive, resulting in problems such as impeding durability.

慣性マス２およびラバー層３の陥没壁８との間に
所定間隙を存するように設けられるものである。 The present invention has been devised in view of the above, and will be specifically explained based on the embodiments shown in Figs. 2 is an inertial mass that is superimposed with the circular plate 1 via a rubber layer 3 adhered to the same plate, and 4 is a recess formed by partially cutting out the inertial mass 2 and the rubber layer 3. They are provided at two locations axially symmetrical to the shaft hole 5 of the circular plate 1. In this way, a stopper 6 made of sheet metal and having a square cross section is welded to the circular plate 1 exposed in the recess 4, and a rubber 7 is coupled to the leg wall of the stopper 6 facing the recess 4. This rubber 7 is provided so that a predetermined gap exists between the inertial mass 2 facing the recess 4 and the depressed wall 8 of the rubber layer 3.
また慣性マス２のダンピング作用を損ねないよ
うに、ストツパ６の背面壁６′と陥没壁８との間
にも間隙を存するようにしている。 Further, a gap is also provided between the rear wall 6' of the stopper 6 and the depressed wall 8 so as not to impair the damping effect of the inertial mass 2.
本実施例は上記構成を有するため、クランク軸
駆動時慣性マス２に過大な回転力が作用しても、
慣性マス２がラバー７を介してストツパ６に衝合

実施例ダンパ装置の固有振動数の低下をも防止で
きるすぐれた作用効果を有する。 Since this embodiment has the above configuration, even if an excessive rotational force is applied to the inertial mass 2 when driving the crankshaft,
Since the inertial mass 2 abuts or engages with the stopper 6 via the rubber 7, an excessive torsional amplitude of the inertial mass and an accompanying temperature rise in the rubber layer 3, as well as cracking of the rubber layer 3 due to this, can be prevented. Furthermore, the vibration control function of the stopper 6 has an excellent effect of preventing a decrease in the natural frequency of the damper device of this embodiment.
