PROBLEM TO BE SOLVED: To accurately lock the connector by restricting the rotating direction of the connector and inhibiting the connector from rotating at a specific position by providing a projection at the specific position on the internal surface of a connector fitting plate. SOLUTION: When an external antenna connector 51 which has a step part 52 at an intermediate part and also has an antenna cable 61 led out of a large- diameter part 53 is locked to the fitting plate 41, a couple of projections 55a and 55b provided at the top of a small-diameter part 54 of the connector 51 are fitted and inserted into a couple of right and left grooves 42a and 42b provided outside a connector insertion hole 43 of the fitting plate 41 and then only the small-diameter part 54 is inserted into the insertion hole 43 and then the connector 51 is rotated by 90 deg.. At this time, a 2nd projection 45 is provided on the internal surface of the fitting plate 41 in contact with one side of the groove 42a opposite the flank of the projection 55a; and then the connector 51 is enabled to rotate only in one direction and the 1st projection 44 is provided at the specific position.
