Description of the Related Art In a conventional cylinder lock, a regular key can be rotated to a lock position or an unlock position in 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 blocked by the tumbler that engages with the groove in the case, there is a risk of unauthorized unlocking due to the breakage of the tumbler. Therefore,
For example, as disclosed in Japanese Patent Application Laid-Open No. 1-315569, a free-turn type cylinder lock has been proposed in which the key cylinder is freely rotated at the time of illegal unlocking in which a rotational force is applied to the key cylinder. The cylinder lock includes a sleeve rotatably arranged in a case and a key cylinder rotatably supported in the sleeve.

ないから、ロック装置を操作することができない。When a regular key is inserted into the key cylinder, the tumbler in the key cylinder is disengaged from the groove formed in the sleeve and the key cylinder can be rotated relative to the sleeve. This allows the sliding ring to engage the lock piece actuating member to operate the locking device. Further, when a different type of key is inserted into the key cylinder, the key cylinder is held in the state of being engaged with the sleeve by the tumbler, so that the key cylinder rotates together with the sleeve. As a result, the locking piece actuating member cannot be rotated, and the locking device cannot be operated.

The lock device disclosed in Japanese Patent No. 315569 has a drawback that the key cylinder cannot be smoothly operated after different kinds of keys are used. That is, in order to automatically return the rotated key cylinder to the initial position in the lock device, a torsion spring is provided between the front plate and the key cylinder. When a dissimilar 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, if the torsion spring is not provided,
When the key cylinder is rotated using a regular key, the key cylinder does not automatically return to the initial position, which makes it difficult to perform a smooth locking or unlocking operation. Also,
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.
