To provide a rotary fit connector that can achieve cost reduction by reducing the kinds of components and that can improve operability by reducing the rotary operation amount when connecting connection terminals to each other, housed in a pair of connector housings.

A rotary fit connector 1 is provided with a pair of connector housings 3A, 3B housing a connection terminal and a junction sleeve 5 having connection cylindrical parts 51 at its both ends to which tips 33 of the connector housings 3A, 3B are fitted rotatably, and the pair of connector housings 3A, 3B can be connected and departed mutually by relative rotary operation between the connector housings 3A, 3B and the junction sleeve 5. The connection terminal is an abutting type terminal 4 with an abutting face 41 installed at its tip, and each of the connector housings 3A, 3B holds the abutting type terminal 4 in a state of the abutting face 41 projecting from the tip of the housing.
