1. A locking structure for a connector comprising: a first connector housing having a flexible arm fixed on a wall of said first connector housing at one end of the arm and providing a latch portion on the other end of the arm, and a disengaging lever portion connected at one end thereof to said latch portion so as to extend along said arm; and a second connector housing having an engaging portion adapted to engage with said latch portion of said first connector housing and to disengageably lock said first connector housing and said second connector housing; wherein said disengaging lever portion rotates with said latch portion around a pivot which is movable when the lock is disengaged, wherein said disengaging lever portion is connected to said first connector housing by means of a hinge, wherein said hinge is disposed at an opposite side of said first connector housing to said latch portion, thereby interposing said pivot between said latch and said hinge. 2. A locking structure for a connector according to claim 1, wherein at least one of said disengaging lever portion and said wall of said first connector housing has a support portion which serves as said pivot of the rotation of said latch portion. 3. A locking structure for a connector according to claim 1, wherein said pivot of the rotation is provided at a substantially same position as said one end of said flexible arm. 4. A locking structure for a connector according to claim 1, wherein said disengaging lever portion comprises a lock disengaging operation section at an opposite side to said latch portion interposing said pivot, and a distance between said pivot and said latch portion is set to be larger than a distance between said pivot and said lock disengaging operation section. 5. A locking structure for a connector according to claim 1, wherein said locking structure further comprises lever side excessive displacement preventing pieces provided on both sides of a finger touch portion positioned at an opposite side to said latch portion, and housing side excessive displacement preventing pieces provided on one of said first and second connector housings, and wherein said lever side excessive displacement preventing pieces are adapted to be abutted to said housing side excessive displacement preventing pieces to thereby prevent an excessive displacement of said disengaging lever portion in a locking direction. 6. A locking structure for a connector according to claim 5, wherein an outer wall of one of said first and second connector housings covers upper parts of said arm up to said latch portion, and an inner face of said outer wall serves as an excessive displacement preventing wall portion whereby said latch portion is adapted to be abutted to prevent an excessive displacement of said disengaging lever portion in a lock disengaging direction. 7. A locking structure for a connector comprising: a first connector housing having a flexible arm fixed on a wall of said first connector housing at one end of the arm and providing a latch portion on the other end of the arm, and a disengaging lever portion connected at one end thereof to said latch portion so as to extend along said arm; and a second connector housing having an engaging portion adapted to engage with said latch portion of said first connector housing and to disengageably lock said first connector housing and said second connector housing; wherein said disengaging lever portion rotates with said latch portion around a pivot which is movable when the lock is disengaged, wherein said disengaging lever portion includes a support portion which serves as a pivot of rotation for the disengaging lever portion and which directly contacts the wall of the first connector housing and wherein a gap is provided between the support portion and the wall when the disengaging lever portion is in an undeflected state.
