PURPOSE: A door lock is provided to prevent a door from opening in any direction by preventing a door from lifting from a rail. CONSTITUTION: For locking doors(10a,10b), a lever(19) is rotated to adhere a friction member(15b) of a mobile pad(16) and another friction member(14a) of a body(12) to a rail(11) by moving the mobile pad toward the rail. The doors don't move due to the friction force of the friction members. Even if the door is lifted up of the rail, the doors are not lifted up of the rail due to the friction force of the friction members. Thereby, the doors are maintained in a lock state.
