PROBLEM TO BE SOLVED: To improve operability of fitting a cover of a recognition portion in a security device provided with the recognition portion on the front of a fitting base body.SOLUTION: A slope 26 is formed on a rear end portion of a boss portion 23 projected from an inner surface of each of right and left side walls 17 of a cover 12. When the cover 12 is arranged on the front of the fitting base body 3, the slope 26 contacts with an overhang portion of an equipment outer shell of the recognition portion to elastically spread both the right and left side walls 17, and the boss portion 23 passes the overhang portion, so both the right and left walls 17 need not be spread with both the hands and the operability is improved. Further, a counterbore hole 28 for accommodating the head 14a of a fitting screw 14 is formed in a rear surface portion of the fitting base body 3, thereby the length of a complete screwing portion of the fitting screw 14 with respect to a screwed hole 25 is never shortened in spite of the formation of the slope 26. |
