There is a device described in the publication, but this device is a covering with an H-shaped cross section with a pair of flanges protruding from both ends, which covers the outer periphery of the handle of the vibrating machine, and inside the brim, there is a cover with a pair of flanges protruding from the handle in the axial direction of the handle. Since the vibration is damped by springs inserted in the cross directions and the human hand is placed between the pair of collars, this method is useful when the equipment is large and the distance between the vibrating machine and the handle is small. However, it has the disadvantage that it cannot be installed, and the hands are restrained by the collars at both ends, which makes it difficult to perform operations such as turning on and off the turn signal with your fingers while gripping the handlebars like on a motorcycle.

きるものである。Function Since the present invention is constructed as described above, in order to install the present invention device on a vibrating machine, a pair of coil springs each having a small ring portion and a large ring portion are used.
It is located at a fixed interval around the outer periphery of the handle of the vibrating machine that generates vibration, and the small ring part is wrapped around the handle outer periphery and fixed, and the outer periphery of the large ring part of the coil spring is fixed against the inner periphery of the metal inner cylinder. ,
Coil springs are installed in pairs coaxially with the handle with a fixed interval in the direction of both ends of the insertion interval, so the coil springs can be inserted from both ends of the handle or metal inner cylinder, making the installation process easy. becomes. Then, the metal inner cylinder is installed by covering and fixing an outer cylinder made of a soft elastic material around the outer periphery of the metal inner cylinder. This installation may be performed at the time of manufacturing the vibrating machine body, or may be installed in a conventionally known commercially available device. With this installation, the handle and the metal inner cylinder do not come into direct contact with each other, but are connected via the coil spring inserted in the insertion interval, so the vibrations generated from the vibrating body and transmitted to the handle are absorbed by the coil spring and the metal inner cylinder. The vibration can be absorbed by the outer cylinder made of a soft elastic material, making it possible to prevent various types of damage to the human body caused by vibration. In addition, the handle of the vibrating aircraft has
Since the coil spring is installed coaxially around the outer circumference of the handle, the vibration isolator is small and lightweight, and can be installed even in places where the distance between the vibration machine and the handle is small, and the vibration isolator can be maintained. This eliminates the need for hands to be tied up and allows users to easily perform actions such as flashing turn signals with their fingers while gripping the handlebars like on a motorcycle.

is not in direct contact with the coil spring 4.
Since the vibrations are generated from the vibrating body 1 and transmitted to the handle 3, the vibrations generated from the vibrating machine body 1 are transmitted to the coil spring 4 to which the small ring part 5 is fixed, and the soft elastic material which is fixed to the large ring part 6 via the metal inner cylinder 7. The vibrations are absorbed by the outer cylinder 8 made of aluminum, and are not transmitted to the fingers of the human body holding the outer cylinder 8, or are transmitted in a weakened manner, so that the vibrations do not cause any damage to the human body. In addition, since the outer cylinder 8 made of a soft elastic material is fixed to the outer periphery of the metal inner cylinder 7, the outer cylinder 8 has good shape stability when held with fingers, and the heavy vibrating machine body 1 can be strongly used for work purposes. Even when pressed, stable and safe operation is possible.
