<p>PURPOSE:To improve the operability for locking/unlocking a door by providing a one-way clutch on the inside of a key cylinder, and connecting it to a door lock system setting the door to the locked or unlocked state via gears and a crank arm. CONSTITUTION:A one-way clutch 64, the first gear 72, the second gear 74, a crank arm 76 and a key rod 16b are provided on the inside of a key cylinder 52 to form a lock device. The one-way clutch 64 transfers only the rotating force in one direction, and the first gear 72 and the second gear 74 engaged with it and rotated by 180 deg. by one reciprocating action of the key cylinder 52 are provided. One end of the second gear 74 is connected to the crank arm 76, and the other end is connected to a door lock system via the key rod 16b. When the key of a door is rotated to either the right or the left from the insertion position, the door can be set to the locked or unlocked state.</p> |
