An electrical connector device providing electrical connections in an electrical circuit for an air bag system, between a rotatable member including a steering wheel and a steering shaft and a fixed member including a steering column. The connector device comprises a movable casing for rotation with the rotatable member, a stationary casing fixedly supported by the fixed member, two chambers defined between the movable and stationary casings and separated radially from each other, an electrical conductor housed in one of the chambers and having one end connected to a terminal on the movable casing and the other end connected to a terminal on the stationary casing, the electrical conductor allowing relative rotation between the movable and stationary casings, and a slip ring and a brush housed in the other chamber and fixed to the stationary and movable casings, respectively. With this arrangement, stable and reliable electrical connection is assured for a long period of time and in a plurality of electrical circuits with a minimum of parts and a simple structure. To permit axial movement of the steering shaft as combined with a power steering mechanism of the rack-and-pinion type, the movable casing is axially movable with respect to the rotatable member, but axially immovable with respect to the stationary casing.
