  In the vehicle body mounting structure described in Patent Document 1, it is possible to prevent the operation cable from being disconnected. However, in the case of this structure, a complicated and special movement is required in the operation when the operation cable is locked to the locking portion, and there arises a problem that the workability of locking the operation cable to the lock mechanism is deteriorated.

On the other hand, if one of the portions constituting the both edges of the notch is formed in a straight line without bending, the cable locking workability becomes easy. There is a problem in that it is easy to come off, and it is easy to come off due to vibration or the like even after mounting the vehicle body. The longer the one portion is extended, the harder it is to release. However, if the portion is extended too much, the extended portion is liable to come into contact with the vehicle body, and the workability of attachment to the vehicle body is deteriorated.

Further, the structure of Patent Document 2 requires a separate member for preventing the cable from being detached, and there is a problem that the number of parts and the cost are increased. Also, with this structure, the operation cable can be prevented from being detached when the lock mechanism is attached to the vehicle body, but the problem that the operation cable is easily disconnected until the lock mechanism is attached to the vehicle body has not been solved.

The present invention has been made in view of the above-described conventional situation, and the operation of locking the operation cable to the lock mechanism is easy, and it is difficult to release the lock until the operation cable is mounted on the vehicle body. It is an object of the present invention to provide a vehicle body mounting structure for a hood lock device that can be reliably prevented from coming off due to vehicle body vibration after mounting the vehicle body.

According to the present invention, a latch of a lock mechanism on the vehicle body side is engaged with a striker on the hood side, and the lock mechanism of the hood lock device in which the engagement is released by operating an operation cable is attached to a vehicle body constituent member. In the body mounting structure,
The mounting bracket of the lock mechanism includes a mechanism supporting portion that supports the latch, and a mounting portion that is bent toward the vehicle body component side following the mechanism supporting portion and is further bent outward in the vehicle width direction. It has a hat shape, and a notch for locking the operation cable is formed in the attachment portion, and one edge portion of the notch portion is constituted by the attachment portion, and the other edge portion is the attachment portion. The rib portion protrudes toward the vehicle body component member from the seating surface attached to the vehicle body component member, and the rib portion is formed on the vehicle body component member when the lock mechanism is attached to the vehicle body component member. It is characterized by being inserted into a hole.

  According to the vehicle body mounting structure of the hood lock device according to the present invention, only the mounting portion of the portions constituting both edges of the notch portion for locking the operation cable is bent in the vehicle width direction, and the rib portion is a vehicle body structural member. Since it extends linearly to the side, it is easier to lock the operation cable to the notch than when both edges are bent. On the other hand, since the rib portion is formed so as to protrude from the seat surface toward the vehicle body component member side, it is difficult for the lock mechanism to be released from the notch portion until the lock mechanism is attached to the vehicle body.

Further, when the lock mechanism is attached to the vehicle body component, the rib portion is inserted into the hole on the vehicle body side, so that the lock mechanism can be temporarily held and the rib portion functions as a detent. The body mounting workability is good.

  Furthermore, in the state where the lock mechanism is attached to the vehicle body side, the operation cable is completely surrounded by the attachment portion of the attachment bracket, the rib portion, and the vehicle body constituent member, so that there is no vehicle deformation or vibration. Will not come off.
