Description of the Related Art A coaxial cable connector having the above-mentioned structure is disclosed in Japanese Patent Application Laid-Open No. 9-19085, for example, in order to prevent rainwater from entering through a threaded portion between a connector body and a clamp.
As described in Japanese Patent Publication No. 8 (1994), an engagement groove is provided on the peripheral side of the connector body, a seal ring is engaged with the engagement groove, and the seal ring is tightened when the connector body and the clamp are assembled.

態は得られない。In the prior art, the fastening fitting is screwed into the connector body and is advanced along the connector body, so that the fastening fitting is assembled to the connector body side so as to be elastically deformed. The sealing state is obtained by sliding the outer peripheral edge of the ring, so to speak, when the inner peripheral surface of the fastener comes into contact with the outer peripheral edge of the seal ring (at the time of the above-mentioned sliding contact), the inner peripheral surface seals the seal ring. Since an external force is applied to push in the forward direction, the seal ring tends to be disengaged from the engagement groove, so that the seal ring tends to be twisted. As a result, a satisfactory sealing state cannot always be obtained.
