PURPOSE:To improve a seal effect and a vibrative isolation effect, by forming a vibro-isolating material by adhesive lamination alternately of a metallic material and an elastic member and interposing the vibro-isolating material between an intermediate structure and a housing so that a laminated face of said vibroisolating material corsses at almost a right angle with the axis of a machine body. CONSTITUTION:A vibro-isolating material 6 is formed by alternately laminating a metallic material and a rubber plate to be adhesively attached. Then this vibro-isolating material 6 is interposed between an intermediate structure 3 and a housing 4 so that a laminated face of said vibro-isolating material crosses at an almost right angle with the axis of a machine body. In this way, the vibro- isolating material 6 provides construction strong against the hydraulic pressure while soft in the radial direction of a shaft 1. Accordingly, vibration generated in the shaft 1 and transmitted to a bearing 2 is not transmitted to the housing 4, resulting in the improvement of a seal effect and a vibro-isolating effect. |
