Claims

[Claims for Utility Model Registration] A locking device comprising a side bar between an outer cylinder and an inner cylinder, and a tumbler unit in the inner cylinder for regulating the movement of the side bar, in which the tumbler unit is engaged and held by the inner cylinder. There is a keyhole in the shaft center of the holder.
A plurality of engaging parts are formed perpendicularly to this keyhole and both ends are open on the side of the holder, and a disk tumbler with a side bar engaging recess formed on each side can be slid into each engaging part. A spring for retracting the engaging recess from the side bar position and a retaining means for securing the end of the disk tumbler in the opening of the engaging portion are provided between the engaging portion and the tumbler. A locking device featuring: The retaining means includes a retaining portion that is continuous with the spring receiving portion of the engaging portion, a retaining portion that is continuous with the tumbler guide surface, and a retaining portion that is continuous with the guide surface of the disc tumbler.
2. The locking device according to claim 1, wherein a stopper part is formed which comes into contact with the retaining part when the end of the tumbler is located on the opening surface of the engaging part.
