Abstract

When an inside lock button is operated for locking, an inner wire of a wire cable is drawn into an outer tube of the wire cable so that a lock lever shifts from an unlock state to a lock state, whereas when the inside lock button is operated for unlocking, the inner wire of the wire cable is pushed out of the outer tube of the wire cable so that the lock lever shifts from a lock state to an unlock state.

Claims

1. A door lock device comprising:

a ratchet lever that is engaged with a ratchet that is in abutting engagement with a latch, and releases the abutting engagement;

a lock lever that shifts between an unlock position where transmission of a door opening operation by an outside handle to the ratchet lever is enabled and a lock position where the transmission of the door opening operation by the outside handle to the ratchet lever is disabled; and

an inside lock button connected to an inner wire of a wire cable that causes the lock lever to shift from the unlock position to the lock position with an operation of locking, and causes the lock lever to shift from the lock position to the unlock position with an operation of unlocking, wherein

when the inside lock button is operated for locking, the inner wire of the wire cable is drawn into an outer tube of the wire cable so that the lock lever shifts from the unlock state to the lock state, and

when the inside lock button is operated for unlocking, the inner wire of the wire cable is pushed out of the outer tube of the wire cable so that the lock lever shifts from the lock state to the unlock state.
