Abstract
A gasket includes a first slope at a first axial end. The fluid device includes a second slope that contacts the first slope. The first slope and the second slope have different gradients. The first slope allows at least the first axial end to be deformed along the second slope. The first slope contacts the second slope with a gradient that varies depending on a gradient of the second slope to seal a gap between the first slope and the second slope.
