A connector comprising: a terminal to be connected to a mating terminal by a relative movement between the terminal and the mating terminal; a connector housing supporting the terminal; wherein the terminal comprises: a first rib; a second rib; and a fitting recess formed by the first rib and the second rib, an elastic support member being mounted to the fitting recess with the elastic support member positioned by the first rib and the second rib, the terminal being fixed to the connector housing with the terminal fitted to a terminal support portion formed in the connector housing via the elastic support member, characterized in that the first rib and the second rib are provided projecting along an entire circumference of a terminal holding portion at both ends of an outer circumference thereof, wherein the fitting recess formed by the pair of ribs and is provided in the outer circumference of the terminal holding portion, and in that the second rib and the elastic support member are in close contact with an inner surface of the terminal support portion, and in that a direction of an axial core of the terminal is displaceable about the second rib as a fulcrum with respect to the connector housing by an elastic deformation of the elastic support member; and in that the connector further comprises a terminal displacement portion displaceably supporting the terminal, wherein the terminal displacement portion comprises: the elastic support member supporting the terminal against the connector housing; a leaf spring contact portion provided to an opposite side of a mating terminal contact portion of the terminal; wherein the terminal displacement portion supports the terminal in a direction orthogonal to a direction of the relative movement between the terminal and the mating terminal. a terminal to be connected to a mating terminal by a relative movement between the terminal and the mating terminal;
