To improve sealability at a lead wire drawing portion. ÄSolutionÜ A connecting portion 14 integrally formed with a covering element 12 made of a synthetic resin and projecting therefrom is provided with an engaging projection 23, and round tubular portions 26 of connection terminals 25 connected with a coil 10 project from the outer surface of the engaging projection 23. Cores 31 of lead wires 30 are connected with the round tubular portions 26 by crimping the round tubular portions 26. A rubber plug 35 having insertion holes 39 which are formed with lips 40 and through which the lead wires 30 are inserted in a watertight manner is provided, and a bottom end portion of this rubber plug 35 is closely adhered to the outer surface of the engaging projections 23 via lips 37. A cover 41 made of a metal plate is fitted on the rubber plug 35, and an insertion end 44 is inserted into an insertion slot 21, and crimping pieces 42, 43 are bent toward locking surfaces 18, 19 at the bottom surface of the connecting portion 14, thereby securing the cover 41 to the connecting portion 14. <IMAGE>
