PROBLEM TO BE SOLVED: To provide a lock device capable of ensuring reliability in switching the locking state.SOLUTION: A lock pin 24 and a rotating piece 25 are attached to each other by engaging an engagement protrusion 33, which is protrusively provided on the lock pin 24, to a guide groove 34 of the rotating piece 25 so that a lower face of the guide groove 34 serves as an unlock guide face 35. Further, a lock guide protrusion 36 is arranged on the rotating piece 25 so that a lower face of the lock guide protrusion 36 serves as a lock guide face 37. When in a locked state, a head 38 of the lock pin 24 is pushed downward by the lock guide face 37 of the lock guide protrusion 36 so that the lock pin 24 is pushed out in a locking direction. When in an unlocked state, the engagement protrusion 33 of the lock pin 24 is pushed upward by the unlock guide face 35 of the guide groove 34 so that the lock pin 24 is pulled in an unlocking direction. |
