Abstract
The present invention relates to a lock cylinder including an outer cylindric block, an inner cylindric block, which defines a key hole, locking function members arranged inside the inner cylindric block, which are intended to cooperate with a key insertable in the key hole, as well as an activating member connected to the inner cylindric block. The inner cylindric block has such dimensions that it is displaceable inside the outer cylindric block, that members are arranged adjacent to the opening of the key hole to fix the inner cylindric block and the outer cylindric block in relation to each other in the axial direction, and a force-exerting member is provided, which applies an axial force to the inner cylindric block in a direction away from the opening of the key hole.
