<p>A sealing member fitting apparatus (1) has a sealing member holding device (30) which holds hollow sealing members (S). The sealing members (S) are transferred from the sealing member holding device (30) to a sealing member transfer device (10) in a sealing member receiving position facing the sealing member holding device (30). The sealing member transfer device (10) is then switched from the sealing member receiving position to a sealing member fitting position facing an electrical wire clamping device (60) which clamps electrical wires (W). Parts of the electrical wires (W) which lead out from the electrical wire clamping device (60) are held in a slidable manner in an electrical wire insertion guide device (70). The electrical wire insertion guide device (70) is moved to its sealing member fitting position to hold covering end parts of the electrical wires (W) and to position the central axis of the covering end parts so that they are substantially coaxial with the central axes of the sealing members (S). The sealing members (S) are then fitted on the covering end parts of the electrical wires (W).
