Claim:
1. A key cylinder device, comprising: a rotor resiliently mounting tumblers that are aligned by insertion of a mechanical key; a rotor case rotatably housing the rotor that is inserted in a direction opposite to an insertion direction of the mechanical key; and a cylindrical sleeve arranged around an outer peripheral surface of the rotor and non-rotatably fixed to an inner surface of the rotor case, wherein outer side surfaces of the cylindrical sleeve directly contact inner side surfaces of the rotor case, wherein the sleeve comprises a hole that allows the tumblers to be disengaged when the mechanical key is inserted and to be engaged when the mechanical key is extracted, and wherein the rotor case is configured to be non-rotatably and directly fixed to a lock body of a vehicle such that the rotor is rotatable relative both to the rotor case and the cylindrical sleeve.
