Abstract
A door lock with a bolt, wherein the bolt pieces of the dual-action bolt are prevented from turning away from each other as the bolt pieces have two projections (24, 26) arranged to cooperate with the inner surface (30) of the front plate. In relation to the support of the bolt piece on the shaft (29), one of the projections (26) is arranged on the opposite side in the axial direction compared to the other away-facing projection.
