Description of the Related Art A conventional cylinder lock can rotate a regular key into a locked position or an unlocked position on a key cylinder having a tumbler that engages with a groove formed in a case. In the conventional cylinder lock in which the rotation of the key cylinder is prevented by the tumbler engaging with the groove in the case, there is a risk that the tumbler is broken and the lock is unlocked. Therefore,
For example, as disclosed in Japanese Unexamined Patent Publication No. 1-315569, a free-wheel cylinder lock has been proposed in which the key cylinder freely rotates in the case of improper unlocking in which a rotational force is applied to the key cylinder. There is. This cylinder lock comprises a sleeve rotatably arranged in a case and a key cylinder rotatably supported in the sleeve.

The locking device disclosed in Japanese Patent No. 315569 has a drawback that the key cylinder cannot be operated smoothly after a different type of key is used. That is, the key that is rotated in the lock device.
A torsion spring is provided between the front plate and the key cylinder to automatically return the cylinder to the initial position. When a different kind of key is inserted into the key cylinder and the sleeve and the key cylinder are freely rotated together, the torsion spring generates a reaction force. However, when the key cylinder rotates more than a certain angle, the torsion spring restricts the rotation of the key cylinder. Therefore, there is a risk that the torsion spring will be damaged or destroyed.
However, if the torsion spring is not provided, the key cylinder does not automatically return to the initial position when the key cylinder is rotated by using a regular key, so that the remote locking or unlocking operation is performed. Has the drawback that it becomes difficult. Further, in the lock device disclosed in the above publication, since the torsion spring is provided in the front part of the lock device, there is a risk of freezing in a cold region.

ることができない難点がある。Further, in the conventional free-turn type cylinder lock, it is necessary to insert a regular key and rotate the key cylinder at a constant angle to connect with the lever. Since the lever does not rotate at all during this rotation, a large rotation angle is required to rotate the lever to a predetermined lock position or unlock position, including a connection operation with the lever. Further, since the sliding parts are interposed between the connecting operations, the parts are worn. Further, since the sliding parts have to be moved in the axial direction of the key cylinder, there is a problem that the total length of the cylinder lock cannot be shortened.

固に形成する必要もない。As described above, according to the present invention, since a cylinder lock having a great resistance to breakage can be obtained, it is possible to effectively prevent a crime such as illegal intrusion or theft. Further, in the cylinder lock of the present invention, when the regular key is inserted into the key cylinder and rotated, the key cylinder and the driving member are always connected, so that preliminary rotation necessary for connecting the driving member is not necessary. . That is, since a component that moves in the axial direction when a regular key is used is not provided in the cylinder lock, a cylinder lock excellent in durability and operability can be obtained. For this reason, the number of sliding parts is smaller than in the conventional case, and the failure of the cylinder lock can be reduced and the life can be extended. Furthermore, since there is no need for a component that moves in the axial direction, the total length of the cylinder lock can be shortened, and it is not necessary to form the front surface firmly.
