DOOR LOCK MECHANISM

摘要

PROBLEM TO BE SOLVED: To enable switching between the lock state and the unlock state with a small number of part items, and also enable switching between the lock state and the unlock state by key operation by making one direction of the key side lever agree with the direction of force applied to the key side lever during the key operation without causing the waste of force. SOLUTION: A second lever side projecting shaft 72 of a moving block 68 is stored in an oblong hole of a second lever 76. The second lever 76 is rotated by an actuator 78. The lower end part of a key side link 26 is connected to the oblong hole 84 of the second lever 76, whereby when the second lever 76 is rotated by the rotation of a key cylinder 18, the moving block 68 is moved vertically to put a door lock mechanism 10 in the lock state or in the unlock state. The key side link 26 is arranged substantially in the vertical direction to align the moving direction with the longitudinal direction.
