Connector

A connector comprising:

• a housing including an opening open toward an opening side;
• a seal ring configured to prevent the entrance of liquid into the housing from the opening side by being at least partly inserted into the opening and resiliently contacting an inner peripheral surface of the opening;
• and
• a retainer including at least one contact portion configured to come into contact with the seal ring, the retainer being configured to hold the seal ring in the housing by the at least one contact portion coming into contact with the seal ring,
• wherein:
• the retainer is mounted on the housing to substantially cover the opening of the housing;
• at least one first drainage port configured to discharge liquid having entered the retainer and adhering to the seal ring to outside is open in a first inner wall of the retainer;
• the retainer includes at least one locking lance that is resiliently displaceable toward a wire and is configured to hold the wire by resiliently contacting the wire;
• the housing includes at least one pressing portion configured to resiliently displace the locking lance to bring a contact portion of the locking lance into contact with the wire;
• and
• when the retainer is mounted on the housing, the at least one pressing portion of the housing is inserted between two displacement preventing portions and one or more projections of the locking lance.
