<p>An object of the present invention is to reliably engage a pair of lock arms and a pair of lock portions as a means for locking an auxiliary housing inserted into a frame in a retained state. An auxiliary housing 20 inserted into a frame 10 is locked in a retained state by the locking action of a pair of resiliently deformable lock arms 13 and a pair of lock portions 21. The lock arms 13 and the lock portions 21 include locking surfaces 17, 23 which are substantially normal to an inserting direction of the auxiliary housing 20 and come into contact with each other with the lock arms 13 and the lock portions 21 engaged in an insertion process of the auxiliary housing 20. When an inserting force exceeding a locking force of the locking surfaces 17, 23 is applied to the auxiliary housing 20, the lock arms 13 are resiliently deformed to disengage the locking surfaces 17, 23.</p> |
