A housing comprising:

• a housing main body comprising:
• a fitting portion configured to be fitted with a mating housing and having a terminal accommodating chamber in which a terminal is accommodated;
• and
• a hood portion which covers a periphery of the fitting portion;
• an annular seal member configured to be attached to a base part of the fitting portion and to seal the fitting portion and the mating housing in a fitting position;
• and
• a retainer configured to be inserted into a retainer accommodating hole and to lock the terminal accommodated in the terminal accommodating chamber, the retainer accommodating hole being formed in the fitting portion and being opened at a side part of the fitting portion,
• wherein an opening portion through which the retainer passes to be inserted into the retainer accommodating hole is formed at a position facing the retainer accommodating hole in the hood portion, the opening portion has an inner shape larger than an outer shape of the retainer;
• wherein a guide portion protrudes into the opening portion from an edge portion of the opening portion and is slidably in contact with the retainer to guide the retainer into the retainer accommodating hole when the retainer is inserted into the retainer accommodating hole, and
• wherein the guide portion has a first side surface and a second side surface, and the seal member extends past the first side surface and the second side surface of the guide portion in a width direction of the housing main body, the width direction being substantially perpendicular to both of a fitting direction in which the fitting portion is fitted with the mating housing and an inserting direction in which the retainer is inserted into the retainer accommodating hole.
