Abstract
The object of the present invention is to provide a sealing structure which enables an insertion member to be removed easily from an inserted member. The sealing structure includes valve body, a mouth ring, an O-ring that is accommodated in an accommodation region formed by an inner peripheral surface of the mouth ring and an outer peripheral surface of the valve body, and prevents the fluid from leaking, and backup rings which are accommodated on both sides of the O-ring in the accommodation region, and restrict a movement of the O-ring. The valve body and the mouth ring are formed with screw parts to be fitted or screwed to each other when they are assembled, and first pressure release grooves are formed in the axial direction so as to extend at least on the inner peripheral surface of the mouth ring between the screw parts and the accommodation region.
