Description of the Related Art Conventionally, a hood lock device of this type swings between a striker attached to a hood and a base member fixed to a body side, as described in, for example, Japanese Utility Model Laid-Open Publication No. Sho 57-21754. A latch member that is attached so as to be able to lock the hood in a closed position by engagement of the striker, and is swingably attached to the base member,
A lock member that maintains the engagement state of the latch member with the striker, and an operation cable that remotely controls the lock member, the operation cable includes an outer cylinder,
An inner wire inserted into the outer cylinder and an outer receiver attached to the outer cylinder are provided.

The base member is provided with a locking wall extending substantially orthogonally to the direction in which the operation cable is provided, and a locking wall for locking an outer receiver of the operation cable with the locking wall. A hole and a notch portion that opens the locking hole and allows the outer receiver to be inserted into the locking hole are formed, and the outer receiver of the operation cable is transferred from the notch portion to the locking hole. And the outer cylinder of the operation cable is locked and held in the locking hole via the outer receiver, and one end in the length direction of the inner wire inserted into the outer cylinder is locked. The other end of the inner wire is connected to the lock member disposed on the inner side of the wall, and the outer cylinder and the inner wire are detoured from the front side of the engine room or the like to the rear. Connected to a nearby operation lever To have.

When the hood is closed and locked to the body side, the striker is engaged with the latch member, and the engagement state between the striker and the latch member is maintained by the lock member. . On the other hand, when the hood is opened, the lock member is swung through the inner wire of the operation cable by operating the lever, and the engagement state of the lock member with the latch member is released, so that the latch member is released. The striker is released.

[0005] As described above, the locking wall for locking the operation cable to the base member is provided substantially orthogonal to the direction in which the operation cable is provided. For example, by holding the outer cylinder via the outer receiver, extending the inner wire from the outer cylinder toward the inside of the locking wall, and connecting the inner wire to the lock member on the distal end side of the inner wire. A driver, wire, or the like is inserted inward from a gap such as a radiator grill or a bumper disposed on the opening side such as an engine room, and the inner wire is directly operated to change the engagement state of the lock member with the latch member. Even if the hood is released and the hood is illegally opened, the inner wall cannot be directly operated by the locking wall.
