Embodiment Construction
[0051] The terms "longitudinal", "transverse", and "upward" described below are preceded by image 3 as a benchmark.
[0052]An auxiliary seal 10 for sealing a cylindrical space 40, the hardness of the auxiliary seal 10 is greater than that of the main seal 20 and has elasticity. When the auxiliary seal 10 and the main seal 20 are both placed in the cylindrical space 40 extending in the longitudinal direction formed by the first member to be sealed 30, the pressure applying member 60 and the pressure receiving member 50, and the auxiliary seal When 10 and the main seal 20 interfere with each other in the longitudinal direction and are placed on the pressure-bearing member 50, the auxiliary seal 10 is defined as using the pressure applicator 60 to apply longitudinal sealing pressure to the auxiliary seal 10 and the main seal 20, When the primary seal 20 deforms laterally and seals against the first member 30 to be sealed, the auxiliary seal 10 deforms laterally and interferes ...
