Lever-type connector

A lever-type connector comprising:

• a housing having support holes;
• a fitting part provided inside the housing and fitted in a counterpart connector;
• a lever that includes a pair of plate-like portions facing each other in an opposed manner, a connection portion connecting the pair of plate-like portions with each other, and projection portions provided respective outside surfaces of the pair of plate-like portions, the lever being rotatably supported by the housing while the projection portions are engaged with the support holes;
• and
• sliding members each includes a guide portion that is slidably supported by the housing and engaged with a part to be guided provided to the counterpart connector, the sliding members being slid depending on a rotation of the lever to depress the part to be guided by way of the guide portion and fit the counterpart connector in the fitting part, wherein
• an inside wall surface of the housing has grooves each extending from an edge portion of the housing to the support holes, and
• the projection portions are allowed to pass through the grooves toward the support holes when a rotational position of the lever about a rotational axis of the lever is a predetermined position.
