COAXIAL CONNECTOR

PROBLEM TO BE SOLVED: To provide a coaxial connector 10 in which engagement is not loosened with a simple structure where after a coaxial connector 10 to which a coaxial cable, an antenna, or the like is connected is engaged with a mating connector, a central conductor 12, an insulator 14, and an external conductor 16 are easily rotatable.SOLUTION: Inside a recessed part 65 formed by an external conductor 16, a coupling 18, and a holding lid 24, an insulation member 20 and an elastic member 22 are fitted, the elastic member 22 holds the external conductor 16, the coupling 18, and the holding lid 24 in a non-contact state, and the insulation member 20 slips in the recessed part 65, so that the central conductor 12, the insulator 14, and the external conductor 16 rotate.
