摘要

An electrical connection box assembled by a lock structure has a first case, a second case, a plurality of lock pieces, an engagement protrusion, a plurality of lock recesses, and an engagement part. The plurality of lock pieces are provided to a peripheral wall of the first case and are elastically deformable toward an inner side of the first case. The engagement protrusion is provided to an outer surface of each lock piece. The plurality of lock recesses are provided to a peripheral wall of the second case. The engagement part is provided bridging each lock recess, the lock pieces being disposed between the lock recesses and the engagement parts, the engagement protrusions engaging the engagement parts to assemble the first and second cases, engagement between the engagement protrusions and the engagement parts being released by deformation of the lock pieces inside the lock recesses.
