Abstract: A connector 10 includes a connector body 20 and a lever 50. The connector body 20 includes a guide portion 30. The lever 50 includes a guide receiving portion 60. The lever 50 is rotatable about a rotary shaft 54 with respect to the connector body 20 to a guide start position where guide by the guide portion 30 is started and a guide end position where the guide by the guide portion 30 is ended. At least one of the guide portion 30 and the guide receiving portion 60 arcuately extends with the rotary shaft 54 as a center. The guide receiving portion 60 contacts the guide portion 30 with a larger contact pressure when the lever 50 is at the guide end position than when the lever 50 is at the guide start position.
