  • the inclined surface 57A of the retainer projection 57 contacts the inclined surface 55A of the housing projection 55 .
  • the retainer projection 57 is displaced inward (that is, forward) and moves to the right of the housing projection 55 so as to overcome the housing projection 55 .
  • the vertical surface 57C of the retainer projection 57 comes into contact with the vertical surface 55C of the housing projection 55, and the leftward movement of the retainer 35 is restricted. This prevents the retainer 35 from being detached from the retainer insertion hole 51 .
  • the width of the retainer opening 52 forming the retainer insertion hole 51 in the front-rear direction (that is, the distance between the front side surface 52A and the rear side surface 52B excluding the housing protrusion 55) is At a portion corresponding to the side portion 71 (that is, a portion located on the right side), the width in the front-rear direction of the insertion side portion 71 of the retainer 35 including the retainer projection 57 is substantially the same as or wider than the width in the front-rear direction of the insertion side portion 71 . is also slightly larger.
  • the longitudinal width of the retainer opening 52 greater than the longitudinal width of the portion corresponding to the insertion side portion 71 at the portions corresponding to the base portion 73 of the retainer 35 (that is, the portions located at the center and the left side)? , or the front-rear direction width of the portion corresponding to the insertion side portion 71 . Accordingly, insertion of the retainer 35 into the retainer insertion hole 51 is not hindered until the inclined surface 57A of the retainer projection 57 contacts the inclined surface 55A of the housing projection 55. As shown in FIG.
  • each inner wall 49 of the female housing 33 has notches 59A formed to correspond to the cross-sectional shape of the retainer 35 at portions corresponding to the retainer insertion holes 51. 59B.
  • a notch portion 59A of the inner wall 49 forming the portion of the retainer insertion hole 51 corresponding to the insertion side portion 71 of the retainer 35 is cut away from a notch portion 59B of the inner wall 49 forming the portion of the retainer insertion hole 51 corresponding to the base portion 73.
  • the retainer 35 having a smaller width in the front-rear direction can be provided.
  • the insertion side portion 71 and the base portion 73 of the retainer having a larger width in the front-rear direction can be held stably.
  • the cylindrical portions 31A of the female terminals 31 are inserted into the terminal accommodating chambers 47 constituting the first terminal accommodating chamber group 101.
  • the first terminal locking portion 83A of the retainer 35 abuts against the rear end of the female terminal 31, thereby preventing the female terminal 31 from moving rearward (that is, separating from the terminal accommodating chamber 47).
  • the second terminal locking portion 83B of the retainer 35 abuts against the rear end of the cylindrical portion 31A of the female terminal 31 inserted into the terminal receiving chamber 47 constituting the second terminal receiving chamber group 102. Rearward movement of the female terminal 31 is prevented.
