As disclosed in Japanese Patent No. 49548, there is a so-called pin tumbler lock provided with a plurality of code pins that are operated by inserting a key and a plurality of driver pins that are in contact with the code pins and are constantly urged by a coil spring. The key used for is a so-called flat key plate. Alternatively, for example, as disclosed in JP-A-61-277782, there is a so-called radial type locking device in which pin tumblers are arranged in the circumferential direction of the rotor. The key used in such a locking device is cylindrical and has a notch portion for a key code formed at the leading edge portion of the key along the circumferential direction.

されている。In addition, as disclosed in Japanese Utility Model Laid-Open No. 2-4736, for example, there is a key whose step surface is circular and has a rod shape, and there is a pinter lock for such a key. In this, the center of the rotor of the cylinder lock is formed in a large hollow shape. The rod-shaped key can be inserted into this cavity. Further, in such a pin tumbler lock, a so-called code pin that comes into contact with a key is specially processed, but this special shape is a code pin having a head, and the head that this code pin has is It serves as a collar so as not to fall into the central cavity. A cylinder lock used in an automobile is a so-called disc tumbler whose tumbler comes into contact with a key as disclosed in Japanese Utility Model Publication No. 60-90659, but in the case of such a plate-shaped disc tumbler, a pin is used. Since the key can be made relatively short compared to the tumbler, it is effective for devices with no space and is also used for coin lockers.

点がある。Since the pin tumblers of the pin tumbler lock are arranged along the longitudinal direction of the rotor with a certain interval, for example, 10 pin tumblers are provided. By doing so, the lock and the key inevitably become long, and thus increasing the number of pin tumblers in itself will increase the size of the shape and key, so the number of pin tumblers must be reduced. Absent. Therefore, there is a disadvantage that the key difference between keys is inevitably reduced. Further, as described above, no matter how many pin tumblers are provided like another cylinder lock,
If the key insertion hole is formed with a large hollow portion into which the rod-shaped key is inserted, the picking tool can be operated very easily, so that there is a big drawback that it can be unlocked easily in a short time.

タンブーなどが錆びつき腐食するという欠点がある。Further, for example, when a cylindrical key having a cylindrical shape is used outdoors, rain, snow, etc. easily enter the cylindrical key and remain there. The vacuum pressure in the cylinder key is badly affected, and it is difficult to discharge it. Therefore, there is a drawback that the remaining water droplets cause the inside of the cylindrical key to rust and corrode. In addition to the corrosion of the cylinder key, if you use it without knowing that water droplets remain inside the cylinder key, this water droplet will remain inside the cylinder lock as it is and penetrate deeply, so the coil spring and pin tambour will rust and corrode. There is a drawback that.

ことにある。In order to eliminate such drawbacks, the object of the present invention is to rotate the rotor with a short cylindrical key by making the key cylindrical and arranging a large number of pin tamboo on the cylinder lock in an inclined manner. In addition to being able to do so, it is possible to easily discharge the water pool that enters into this cylindrical key.
