Connector

A connector comprising a terminal that includes a box-shaped portion to which a mating terminal is inserted and connected and that is attached to an end of an electric wire, a housing that includes an accommodating hole for accommodating the box-shaped portion, and a retainer that is capable of being at a first position and a second position by being attached to the housing in a manner capable of being displaced in an intersecting direction intersecting with an insertion direction of the box-shaped portion into the accommodating hole, wherein

• when inner surfaces of the accommodating hole of the housing that face each other are given as an upper surface and a lower surface, a pressing piece having a cantilever shape is formed on the upper surface in a manner protruding toward the lower surface, and a protrusion is formed on the lower surface in a manner protruding toward the upper surface,
• the retainer includes a protruding portion that protrudes in the intersecting direction, on an extension of the accommodating hole, and
• when the retainer is at the first position, the box-shaped portion is allowed to be inserted into the accommodating hole, and the box-shaped portion inserted in the accommodating hole is pushed by the pressing piece and displaced in the intersecting direction so that a primary locking state is reached due to a projecting portion that is a part of a step portion formed on the box-shaped portion and that is provided on the insertion direction side of the step portion in a manner protruding in an opposite direction from the insertion direction being caught by the protrusion and engaged and retained by a recessed portion formed on the protrusion and a rear end of the box-shaped portion being caught and retained by the protruding portion.
