摘要

A first connector housing of a first connector includes a fitting concave having an inner wall portion extended in a fitting direction X and formed in substantially a circular shape, and the inner wall portion has a first step portion extended perpendicular to the fitting direction X and projected inward. A second connector housing of a second connector includes a fitting convex having an outer wall portion extended in the fitting direction X and formed in substantially a columnar shape, and the outer wall portion has a second step portion indented inward corresponding to the first step portion. A spacer is projected from at least two positions of a part of the outer wall portion and the second step portion in a temporary locking position, and is sunken in the outer wall portion or arranged in the same plane as the outer wall portion in a regular locking position.
