A connector device includes first and second connectors including first and second housings. The second housing has a recess that receives the first housing. The first housing is connected to one end portion of a cable and has a first opening portion, which allows the other end portion of the cable to extend to the outside, on a peripheral wall at one side. An outer peripheral surface of the peripheral wall includes an inclined surface at the other side. The inclined surface is inclined so as to approach a bottom portion of the recess while extending in a direction from the one end portion toward the other end portion of the cable. The inclined surface is brought into contact with the recess so that the first connector is moved relative to the second connector in the direction from the one end portion toward the other end portion.
