There is disclosed a connector for an electric car which can be of a small size, and the cost is reduced, and the efficiency of a fitting operation is enhanced. A female terminal is mounted in a tubular female housing, and a slide cover is slidably mounted on an outer periphery of the female housing. Tapered holes are formed in an electrical contact portion, and ball bearings are received respectively in the tapered holes. Projected portions for limiting outward movements of the ball bearings are formed on an inner peripheral surface of the slide cover. A groove, in which the ball bearings, projected into a bore of the electrical contact portion, are engageable, is formed in the male terminal.
