Further, since the inner surface 5A of the hood portion 5 and the inner surface 41A of the holding portion 41 of the lever 7 are substantially flush, the dimension of the lever connector 1 can be reduced in the direction in which the lever 7 is assembled.

Further, in order to assemble the lever 7 to the housing body 9, the lever 7 is assembled through an opening 37A which is opened in a direction opposite to the direction in which the connectors 1 and 2 are fitted. In addition, by performing an operation of assembling the shaft portion 35 and the bearing portion 36 while narrowing and deforming the two leg pieces 47 of the lever 7, the lever 7 is housed in the deformation regulating portion 34. Therefore, the operation of assembling the lever 7 rotatably and the operation of accommodating the lever 7 in the hood portion 5 can be performed by one operation.

The end surface of the lever 7 on the side facing the mating connector 2 is covered with a protective surface 38 that closes the front portion of the deformation restricting portion 34. For this reason, the front end portion of the lever 7 is not exposed to the outside, and is protected from external force. The lever 7 is mounted inside the hood 5 of the housing body 9. For this reason, compared with the length of the conventional cam part 108, the cam part 6
Can be shortened by the thickness of For this reason, the strength of the cam portion 6 can be improved.

The present invention is not limited to the above-described embodiment. For example, the following ones are also included in the technical scope of the present invention. (1) In the present embodiment, the direction of assembling the lever to the housing is opposite to the direction in which both connectors are fitted.
