  • Rubber gasket and seal structure using the same
    Patent number: 8814174
    Abstract: A rubber gasket of annular shape adapted to be interposed between two objective members to be sealed and fastened to each other and a seal structure for sealing between two objective members to be sealed and fastened to each other using the gasket. The rubber gasket comprises an integrally molded body made of elastomer having a cylindrical body, a flange-shaped portion, and an annular core member, the flange-shaped portion extending outward from one end of the cylindrical body in axial direction along an entire outer circumferential surface, the annular core member being embedded in the flange-shaped portion along an entire circumference.
    Type: Grant

  • Seal Structure
    Publication number: 20120091665
    Abstract: A seal structure for sealing a penetrated portion through which a rotary shaft passes between a cover member and the rotary shaft. A seal member is fitted onto the rotary shaft in a manner that the rotary shaft can rotate relative to the seal member, and the elastic buffer member is provided for connection between the seal member and the cover member at the penetrated portion. The seal structure can keep sealing performance by reducing the influence of movements such as vibration and thermal expansion of the cover member and the influence of process tolerance of the cover member on the sealing performance of the seal member attached to the penetrated portion between the cover member and the rotary shaft penetrating the cover member.
