Engages with the locking hole 65 of the wall 57.

  In the example of FIG. 7, the holder main body 60 is pushed in a state of being inclined downward. However, for example, the holder main body 60 is pushed in with the abutting wall 29 in a horizontal state, or is abutted using a horizontal rear holder without the hinge 59. It is also possible to push in with the wall 29. However, in this case, the inclined surface 13 of the base member 2 is not used (unnecessary), and in FIG. 1, the connector is set not horizontally but horizontally.

  In the above embodiment, the side walls 52 of the rear holder 36 are gradually rotated in the closing (insertion) direction by the inclined surface 13 of the base member 2. It is also possible to rotate the rear holder 36 in the closing direction at once by a connector push-down operation at the tip of the four projecting walls 41. However, there is no concern that the insertion posture of the connector 35 into the connector housing chamber 18 is disturbed by the elasticity (repulsive force) of the hinge 46.

  In the above embodiment, the slide member 3 and the operation member 4 are formed separately, and the slide member 3 is slidably engaged with the base member 2 with the bolt 6, and then the slide member 3 is retracted. Although the operation member 4 is fixed with the bolts 8, the structure can be further simplified and the slide member 3 and the operation member 4 can be integrally formed (in this case also, the portion having the contact wall 29 is provided). A portion having the slide member 3 and the protruding wall 41 is referred to as an operation member 4).
