| 摘要 | PURPOSE:To decrease the vibration transmitted to a cylindrical holder significantly, by letting a vibration absorbing coil spring, which is inserted between a support and the cylindrical holder, form a serial coil spring consisting of inner and outer ring portion of different diameters, and thereby increasing the vibration absorbing capacity. CONSTITUTION:A vibration absorbing coil spring 4 consists of an inner ring portion 5 and an outer ring portion 6, the diameters of which are different. It is located along both internal peripheries inside a cylindrical holder 3. The inner surface 7 of the inner ring portion 5 of a smaller diameter is fitted to the outer surface 8 of a support 2, while the outer surface 9 of the outer ring portion 6 of a larger diameter, fitted to the inner surface 10 of the cylindrical holer 3. The vibration transmitted to the support 2 travels first to the inner ring portion 5 and then to the serial spiral coil. During which process, the vibration is damped due to vibration-abosrbing action and the vibration is conveyed to the outer ring portion 6, resulting in a decreasing and subsequent damping of the vibration transmitted to the cylindrical holder 3, touching the outer ring portion 6. | ||||||
