ド７の動きを拘束して防振作用を行う。(Function) The vibration isolator of the present invention is used by connecting either the support cylinder 1 or the piston rod 7 to a vibration-isolating target such as a piping system, and the other to a support such as a structure. When the object to be vibration-proofed vibrates and the piston rod 7 is moved in and out of the support cylinder 1, the movement of the piston rod 7 is restrained by the sliding resistance of the snap ring 6, thereby providing a vibration-proofing effect.

いる。The snap ring 6 is a commercially available one having a C-shape, for example, and is fitted onto the outer periphery of the piston rod 7 while being stretched out against elasticity. Therefore, the snap ring 6 elastically grips the outer periphery of the piston rod 7 so that it can freely slide, and provides resistance to the sliding movement of the piston rod 7 in the axial direction.

グ６の数を加減すればよい。The vibration isolator of this embodiment is used by connecting either the support cylinder 1 or the piston rod 7 to a vibration-isolating target such as a piping system, and the other to a support such as a structure. When the object to be vibration-proofed vibrates and the piston rod 7 is moved in and out of the support cylinder 1, the movement of the piston rod 7 is restrained by the sliding resistance of the snap ring 6, and the anti-vibration effect is achieved. In order to reduce the vibration force to Wsm, the lid 4 may be removed and the number of snap rings 6 may be adjusted.
