To provide a cylinder lock, a clutch device and a locking/unlocking device with this cylinder lock and clutch device, capable of reducing cost, and capable of miniaturizing and simplifying the whole structure.
The locking/unlocking device has the cylinder lock 2 operating by insertion of a match key K, an operation handle 3 generating locking/unlocking motion for locking and unlocking a lock mechanism, and the clutch device 8 transmitting the locking/unlocking motion of the operation handle 3 to the lock mechanism by operation of the cylinder lock 2. The cylinder lock 2 includes a case 5, a key plug 7 advancing and retreating in its inserting/extracting direction by insertion/extraction of the match key K, and a protrusion 7B outputting advancing-retreating motion of the key plug 7 as intermittent motion of the clutch device 8. The clutch device 8 includes a switching member 9 operating by receiving the intermittent motion from the cylinder lock 2, and a clutch 8A having an inputting clutch element 10 and an outputting clutch element 11 for engaging/separating by operation of the switching member 9.
