Description of the Related Art For example, members constituting a vehicle body of a vehicle are provided with a dynamic damper having a natural frequency equal to the resonance frequency of the members, so that the vibration generated by the engine of the vehicle is dynamic. The damper absorbs the vibration of the members and reduces the vehicle noise.
That is, as an example of such a dynamic damper, a dynamic damper 110 as shown in FIG. 6 is known, and a conventional technique will be described based on this figure. In this dynamic damper 110, a cylindrical mass member 118 coated with a rust preventive is arranged on a plate 114 to which a bolt 112 for screwing is fixed, and vulcanized and bonded between them. An elastic member 116 made of rubber for connecting the two is interposed between them.

の接着力を低下させる問題があった。However, when a long round bar is used, the material cost and the cutting cost are high. In the case of processing cast iron, in addition to high processing cost, it takes cost to remove the metal soap applied to the surface for rust prevention, and when the metal soap is not sufficiently removed, the rubber elastic body is used. When vulcanizing and adhering the mass member, the adhesive force is reduced. Also, when using a stack of multiple plate materials directly, the processing oil (press oil) may remain between the plate materials, or the acid of the pickling of the base treatment may remain. There is a problem that the liquid exudes due to the high temperature at the time of the vulcanization adhesion and reduces the adhesive force between the elastic body and the mass member.

その分製造費が低減される。In addition, in the mass member of the dynamic damper of the present invention, the surface of each of the plurality of press plates is preliminarily coated with an adhesive under the pretreatment for adhesion, and the elastic material such as rubber is applied between the plate members. Since the body is arranged and these are vulcanized and adhered, processing oil and pickling acid, etc. may remain between the press plates like the mass member in which conventional press plates are directly laminated. The adhesion between the elastic member and the mass member becomes reliable. In addition, according to the present invention, it is not necessary to perform welding for connecting the press plates as in the case of the conventional mass member of the laminated body, so that the manufacturing cost can be reduced accordingly.

Since it is thin, the displacement of the elastic body between the plate materials upon receiving a vibration input is extremely small, and the original characteristics of the dynamic damper are not impaired. Moreover, as described in claim 2, the displacement can be further suppressed by providing the displacement regulating means on the one surface and the other surface of the plate material on the stacking side.

Does not need to consider the occurrence of rust on the plate. Therefore, the process of applying a rust preventive agent such as metal soap or removing it from a specific place like a conventional round bar or a mass member made by casting can be omitted, and the manufacturing cost can be reduced, and the rust preventive agent can be reduced. The problem of defective adhesion between the elastic member and the mass member due to leakage of the removed agent is solved.

良く容易に必要な質量を得ることが出来る。Next, the function and effect of the dynamic damper 10 according to this embodiment will be described below. Since each plate material to be laminated is pre-bonded and then vulcanized to rubber, there is no residual oil or acid during processing unlike the conventional laminated dynamic damper, and the rubber and mass as the elastic member 17 are not left. The vulcanization adhesion between the members and the vulcanization adhesion between the plate materials become strong and stable. Further, since the entire outer circumference of the mass member 11 is covered with elastic rubber, it is not necessary to perform a treatment such as painting to prevent the generation of rust on the surface of the mass member, and a waste material can be used as the plate material. Since the cost of pressing the plate material is low, the dynamic damper manufacturing cost can be reduced. Further, also when setting the mass required for the mass member, it is sufficient to simply additionally laminate the plate materials subjected to the press work, and the necessary mass can be easily obtained.

In the second embodiment, when the dynamic damper according to the present invention is attached to the vibrating body and is vibrated in the lateral direction in FIG. 4, the lateral displacement of the plate member 13 is suppressed as much as possible.
It is also possible to provide a pair of protrusions 20 on the left and right of the round hole 12 of one plate member of the adjacent plate members, and to provide a concave portion 21 on the surface of the other plate member facing the plate member so as to face the protrusion and to fit the protrusion. is there. That is, the protrusion 20 and the recess 21 form a pair to constitute a displacement regulating means. By configuring as in the present embodiment, the narrow interval filled with the elastic body between the plate materials becomes uniform, and the dimensional accuracy is improved. Further, the minute movement between the plate materials (deviation between the plates) is further reduced, and the vibration characteristic is improved.
