Abstract

PURPOSE:To obtain a give spring constant and a good ground by loading an conductive elastic material between horizontal plate parts of upper and lower mounting plates provided with projected fixing-connecting tools, and loading a rubber block between upper and lower inclined plate parts formed by bending the mounting plates at the ends of the horizontal plates parts at an abtuse angle. CONSTITUTION:Upper and lower mounting plates 7, 8 are formed by horizontal plate parts 7a, 8a and inclined late parts 7b, 8b formed by bending the mounting plates at the ends of the horizontal plate parts at an abtuse angle, and fixing- connecting tools 11 are attached to the horizontal plate parts 7a, 8a so as to be projected from the plate parts, and further, a coil spring 10 is loaded between the horizontal plate parts. Further, a rubber block 9 is fixed between the inclined plate parts 7b, 8b. When a pipe frame is electrically connected through the fixing-connecting tools, 11 and the coil spring 10 to apparatuses of a generator or an engine, it functions as a ground, and a give spring constant can be arbitrarily obtained by the use of combination of the above members.

題がある。However, with the former, which has a ground wire built into the rubber block, the anti-vibration properties of the anti-vibration rubber are somewhat difficult, and
There was a problem in that it was difficult to incorporate the ground wire into the rubber block. In addition, in the latter case, where the ground wire is connected between the upper and lower mounting plates outside the rubber block, the upper and lower mounting plates move relative to each other in the front, back, left, and right directions, which causes repeated deformation force to act on the ground wire and cause it to break. There is a problem that sometimes happens.
