PROBLEM TO BE SOLVED: To position a lock means without visual confirmation. SOLUTION: Even if a lock arm 31 and a receiving part for lock 40 are deviated in the peripheral direction when both connector housings 10, 20 are fitted mutually, a groove 44 and a rib 34 are mutually fitted when the lock arm 31 and the receiving part for lock 40 are matched by rotating both connector housings 10, 20, and the fitting operation proceeds while both connector housings 10, 20 are positioned in the peripheral direction. When both connector housings 10, 20 reach a normally fitted condition, the lock arm 31 and the receiving part for lock 40 are mutually locked and enter a lock condition. Since a means for positioning the lock arm 31 and the receiving part for lock 40 is provided in the connector housings 10, 20, it is unnecessary to position the lock means by visual confirmation.
