A retainer (44) is pivoted between a partial locking position and a full locking position. A lock (43) restricts a displacement of the retainer (44). A retracted portion (50) is formed in an area (41R) of a facing wall (41) behind the retainer (44) to mold the lock (43) and retracted from an insertion path for a male terminal fitting (10) as compared with an area (41F) of the facing wall (41) before the retainer (44). The retainer (44) includes a restriction (48) for restricting the inclination of the male terminal fitting (10) by being so displaced, at the partial locking position, that a rear end of the male terminal fitting (10) moves toward the retracted portion (50). ## Claims ### Claim 1 A connector, comprising: a housing formed with at least one terminal accommodating chamber having opposite front and rear ends and opposite first and second walls extending between the front and rear ends, the second wall having a facing surface facing into the terminal accommodating chamber, the terminal accommodating chamber being configured for receiving a male terminal fitting from behind; a front wall at the front end of the terminal accommodating chamber; an insertion hole penetrating through the front wall for allowing insertion of a tab of the terminal fitting therethrough when the terminal fitting is inserted in the terminal accommodating chamber; a locking lance projecting from the first wall and engageable with a main body of the terminal fitting for retaining the terminal fitting in the terminal accommodating chamber; a mold removal space between the first wall and the locking lance and being open through the front wall, the mold removal space communicating with the terminal accommodating chamber; the front wall including a partition between the mold removal space and the insertion hole; a mounting hole formed through the second wall at a position rearward of the locking lance; a retainer pivotably connected to the second wall rearward of the mounting hole and displaceable between a first position where insertion of the terminal fitting into the terminal accommodating chamber is permitted and a second position where the terminal fitting is locked and retained in the terminal accommodating chamber; a lock provided forward of the mounting hole to restrict a displacement of the retainer; a retracted portion formed in an area of the second wall from the mounting hole to the rear end of the terminal accommodating chamber to mold the lock and retracted from an insertion path for the male terminal fitting; and a restriction projecting from a surface of the retainer substantially facing the terminal accommodating chamber, the restriction having a maximum projecting portion aligned with the facing surface when the retainer is in the first position for restricting inclination of the male terminal fitting toward the retracted portion when the retainer is at the first position, the restriction further having a flat pressing surface forward of the maximum projecting portion and pressing the terminal fitting toward the first wall when the retainer is in the second position and a guiding surface rearward of the maximum projecting portion and being sloped to guide the terminal fitting into the terminal accommodating chamber and toward the insertion hole when the retainer is in the first position. ### Claim 2 (depends on 1) The connector of claim 1, wherein the partition partitions the mold removal space and the insertion hole in a non-communicating manner. ### Claim 3 (depends on 1) The connector of claim 1, wherein the retainer is arranged to at least partly close the mounting hole. ### Claim 4 (depends on 3) The connector of claim 3, wherein the lock is formed at an edge of the mounting hole. ### Claim 5 (depends on 1) The connector of claim 1, wherein the main body has slide-contact portions at two positions on the first wall spaced apart in forward and backward directions and that slide in contact with a slide-contact surface of the first wall of the terminal accommodating chamber. ### Claim 6 (depends on 5) The connector of claim 5, wherein the restriction restricts an inclination of the male terminal fitting by contacting a part of the terminal main body between the slide-contact portions when a front end of the tab is behind and near the partition. ### Claim 7 (depends on 1) The connector of claim 1, wherein the retainer is pivotally displaceable about at least one hinge unitary to the housing and the retainer. ### Claim 8 (depends on 1) The connector of claim 1, wherein a formation area of the restriction in a width direction is only a central range of the terminal accommodating chamber. ### Claim 9 A connector, comprising: a housing having opposite front and rear ends and opposite first and second walls extending between the front and rear ends, at least one terminal accommodating chamber formed between the first and second walls and extending from the rear end of the housing toward the front end, a locking lance cantilevered forward from the first wall and configured for locking a terminal fitting in the terminal accommodating chamber, the second wall having a facing surface facing the locking lance, a mounting hole formed through the second wall at a position rearward of the locking lance, a lock formed on the second wall and facing rearward into the mounting hole, and a retracted portion formed in an area of the second wall from the mounting hole to the rear end of the housing to mold the lock, a distance from the first wall to the retracted portion exceeding a distance from the first wall to the facing surface; a retainer pivotably connected to the second wall rearward of the mounting hole and displaceable between first and second positions in the mounting hole, a distance from the first wall to the retainer being no less than the distance from the first wall to the facing surface when the retainer is in the first position, the distance from the first wall to the retainer being less than the distance from the first wall to the facing surface when the retainer is in the second position; and a restriction projecting from the retainer and having a maximum projecting portion aligned with the facing surface when the retainer is in the first position for restricting inclination of the terminal fitting toward the retracted portion when the retainer is at the first position, the restriction further having a flat pressing surface forward of the maximum projecting portion and pressing the terminal fitting toward the first wall when the retainer is in the second position and a guiding surface rearward of the maximum projecting portion and being sloped to guide the male terminal fitting into the terminal accommodating chamber when the retainer is in the first position. ### Claim 10 (depends on 9) The connector of claim 9, wherein the retainer is pivotally displaceable about at least one hinge unitary to the housing and the retainer. ### Claim 11 (depends on 9) The connector of claim 9, wherein a formation area of the restriction in a width direction is only a central range of the terminal accommodating chamber. ### Claim 12 (depends on 9) The connector of claim 9, wherein the housing further comprises a front wall with at least one tab insertion hole penetrating through the front wall for allowing insertion of a tab of the terminal fitting when the terminal fitting is inserted in the terminal accommodating chamber. ### Claim 13 (depends on 12) The connector of claim 12, wherein the housing further comprises a mold removal space between the first wall and the locking lance, the mold removal space being open through the front wall and communicating with the terminal accommodating chamber. ### Claim 14 (depends on 13) The connector of claim 13, wherein the front wall includes a partition between the mold removal space and the insertion hole.
