KEY CYLINDER DEVICE |
| 摘要 |
A key cylinder device includes a cylindrical rotor case, a rotor rotatably enclosed in the rotor case, a sleeve fixedly disposed between the rotor and the rotor case, and a tumbler moving in a radial direction inside the rotor by insertion and extraction of a mechanical key into and from the rotor. The sleeve includes a hole not engaged with the tumbler by the insertion of the mechanical key and engaged by the extraction of the mechanical key, and a dividing wall formed at a middle of the hole, the dividing wall receiving the tumbler. A part of the dividing wall is engaged with a recessed groove formed on an inner peripheral surface of the rotor case. |
