An elastic holding body 16 is provided between 12 and 14. The connecting plates 12 and 14 are formed in a substantially rectangular plate shape that is elongated along the width direction of the apparatus in plan view, and are parallel to each other. Here, the longitudinal direction of the connecting plates 12 and 14 substantially coincides with the shearing direction (arrow S direction) which is the operation direction of the apparatus. Moreover, the connection plates 12 and 14 are formed of a metal plate (for example, an iron plate) having a constant thickness, and are subjected to surface treatment such as rust prevention treatment as necessary.

  The elastic holder 16 is configured by molding metal fibers made of, for example, steel or stainless steel into a substantially rectangular shape. Specifically, the elastic holder 16 is, for example, a metal fiber having a predetermined weight. Is pressed into a press mold and compressed, welded or bonded, or metal fibers are knitted three-dimensionally. As a result, atypical continuous pores are formed at a substantially constant density inside the elastic holder 16.

  The elastic holding body 16 is formed in a substantially rectangular shape elongated along the shearing direction in plan view, and the dimension along the shearing direction is shorter by a predetermined length than the dimension along the shearing direction of the connecting plates 12 and 14. . The elastic holding body 16 has an upper end surface fixed to the lower surface side of one connecting plate 12 by welding or adhesion, and a lower end surface fixed to the upper surface side of the other connecting plate 14 by welding or adhesion.

  Here, the elastic holding body 16 has elasticity along the thickness direction, the shearing method, and the synthesis direction thereof, and the deformation amount in these directions is within a predetermined size (elastic limit) or less. It can be regarded as a substantially elastic body.

  The voids of the elastic holding body 16 are filled with a viscoelastic body 28 made of a thermoplastic elastomer such as an acrylic polymer or a styrene polymer. The viscoelastic body 28 is fixed to the metal fiber forming the elastic holding body 16 by vulcanization adhesion. Thereby, the viscoelastic body 28 is held by the elastic holding body 16, and the viscoelastic body 28 and the elastic holding body 16 are always elastically deformed integrally.

  Next, a manufacturing method of the vibration damper device 10 configured as described above will be described with reference to FIG.

  When the vibration damper device 10 is manufactured, first, as shown in FIG. 2A, a pair of connecting plates 12 and 14 formed in a substantially rectangular shape and an elastic holding body 16 formed in a rectangular parallelepiped shape are provided. As shown in FIG. 2B, the upper end surface and the lower end surface of the elastic holding body 16 are fixed to the lower surface side of the connecting plate 12 and the upper surface side of the connecting plate 14, respectively, by welding (adhering step).

  In the vibration damper device 10, when vibration along the shearing direction is input to one or both of the connection plates 12 and 14, one of the connection plates 12 and 14 is in relation to the other as shown in FIG. While relatively moving along the shear direction, shear deformation occurs in the elastic holding body 16 and the viscoelastic body 28. At this time, since the viscoelastic body 28 has viscoelasticity, the input vibration is attenuated by the viscoelastic body 28 by the deformation (shear deformation) of the viscoelastic body 28 by the input vibration along the shear direction. Thus, vibration transmission along the shearing direction between the connecting plates 12 and 14 is suppressed.

  In the vibration damper device 10 described above, the elastic holding body 16 having a three-dimensional shape and elasticity is fixed to the pair of connecting plates 12 and 14, and the viscoelastic body 28 is in the gap of the elastic holding body 16. And is held by the elastic holder 16, vibration having a large amplitude along the shearing direction is transmitted to the viscoelastic body 28 via the connecting plates 12 and 14, and the viscoelastic body 28 is transmitted by this input vibration. Even if excessive deformation occurs along the shear direction, the viscoelastic body 28 itself has an elastic restoring force, and the elastic restoring force of the elastic holding body 16 acts on the viscoelastic body 28. Therefore, when the input of vibration to the viscoelastic body 28 is stopped, the viscoelastic body 28 can be accurately restored to the initial shape before vibration transmission by the restoring force of the viscoelastic body 28 itself and the restoring force acting from the elastic holding body 16. To the viscoelastic body 28 The strain along the cross direction remains can be effectively suppressed.

  Moreover, in the manufacturing method of the vibration damper device 10 according to the present embodiment, the elastic holding body 16 is fixed to the pair of connecting plates 12 and 14 in the fixing process, and then is filled in the gap in the elastic holding body 16 in the filling process. When the elastic holding body 16 is fixed to the pair of connecting plates 12 and 14 by filling the viscoelastic body 28 made of thermoplastic elastomer and holding the viscoelastic body 28 by the elastic holding body 16, this elasticity Since the viscoelastic body 28 does not exist in the gap of the holding body 16, welding is performed at the time of performing the fixing process as compared with the case where the elastic holding body 16 filled with the viscoelastic body 28 is fixed to the connecting plate 12 by welding.

That is, first, the outer peripheral surface and the inner peripheral surface of the elastic holding body 16 are fixed to the inner peripheral surface of the outer cylinder fitting 32 and the outer peripheral surface of the mounting bracket 34 by welding (fixing step), respectively, and then these are placed in the mold cavity. The thermoplastic elastomer loaded as an insert core and in a molten state is filled into the voids of the elastic holder 16. The thermoplastic elastomer filled in the elastic holding body 16 is cooled and cured in the mold, and vulcanized and bonded to the metal fiber forming the elastic holding body 16 to obtain a viscoelastic body 28 (filling step). . Thereby, the manufacture of the vibration damper device 30 is basically completed. Thereafter, the split mold constituting the mold is disassembled, and the vibration damper device 30 is taken out from the mold.

At this time, since the viscoelastic body 28 has viscoelasticity, the input vibration is attenuated by the viscoelastic body 28 by the deformation (shear deformation) of the viscoelastic body 28 by the input vibration along the shear direction. Thus, vibration transmission along the shearing direction between the outer cylinder fitting 32 and the attachment fitting 34 is suppressed.

  Also in the vibration damper device 10 described above, the elastic holding body 16 having a three-dimensional shape and elasticity is fixed to the outer cylinder fitting 32 and the attachment fitting 34, which are a pair of connecting parts, and is also made of rubber. The elastic body 28 is filled in the space of the elastic holding body 16 and is held by the elastic holding body 16, so that the outer cylinder fitting 32 or the mounting fitting 34 is attached in the same manner as the vibration damper device 10 shown in FIG. 1. Even if vibrations along the shear direction are transmitted to the viscoelastic body 28 via the input vibration and excessive deformation occurs along the shear direction due to this input vibration, the viscoelastic body 28 itself has an elastic restoring force. In addition, since the elastic restoring force of the elastic holding body 16 acts on the viscoelastic body 28, when the input of vibration to the viscoelastic body 28 is stopped, the restoring force and elasticity of the viscoelastic body 28 itself. Restoration acting from the holding body 16 The viscoelastic body 28 accurately be restored to its initial shape before vibration transmission, the strain along the shear direction from remaining can be suppressed effectively in the viscoelastic body 28 by.
