が外されるものである。Among the conventional automobile hood lock mechanisms, there is a secondary latch that is disengaged from the locking hole provided on the engine hood side, especially in the center of the engine hood, and lock S is released (disengagement between the main latch and the striker). This is to keep the engine hood closed even when the vehicle is running, so that the engine hood does not close while the vehicle is running. Figures 1 and 2 show the hood lock mechanism used in such automobiles with a front-opening engine hood.
With the pace plate fixed at O, this base plate 1
In addition to the main latch 2 that engages and disengages from the stone 1 fixed to the engine hood 11 via a bracket 5, the main latch 2 engages and disengages from the locking hole 7 formed in the bracket 5 of the striker 6 on the front surface of the pace plate 1. The secondary latch 3 is pivotally supported. The main latch 2 and the striker 6 are unlocked only by operating inside the vehicle via the control cable 9, and the secondary latch 3 is unlocked between the front edge of the engine hood 11 and the vehicle body by the aforementioned unlocking. Insert your finger into the gap created by the set spring 4.
By rotating against force, the engagement with the locking hole 7 is released.

0, and is far away from the gap for secondary launch operation that is created between the front edge of the engine hood 11 and the front bumper 12 when the lock is released. The part that bends in a crank shape with respect to the latch 3 is the base end 8a.
The operation lever 8 is tilted forward and extended downward, and the operation lever 8 is used to release the secondary latch 3.
The locking hole 7 can be disengaged from the locking hole 7.

なってしまう不具合を生じ易いという問題があった。However, since the base end of the operating lever 8'@8a is located above the support on the side edge of the secondary latch 3, it is difficult to open the engine hood 11 and maintain the functional parts in the engine compartment. During inspection, etc., if a worker mistakenly touches the tip of the operating lever 8 and an external force F is applied to the lever 8 from above as shown in FIG. By applying a bending load y with the support shaft 13 as a fulcrum from a position above the support shaft 13,
As shown by the chain line in Figure 3, the secondary latch 3 falls down and becomes deformed, causing the position of the tip hook portion 3a to shift, making the engagement with the locking hole 7 uncertain, and the engagement is released. There was a problem in that it was easy to cause a problem in which the operating force became heavy.

提供することを目的とするものである。Purpose of the Invention In view of the conventional situation, the present invention has been developed to prevent the upper side of the latch, where the hook portion is located, from collapsing and deformation even if a bending load is applied to the secondary latch, thereby ensuring the launch function and achieving reliability and quality. It is an object of the present invention to provide a hood lock mechanism that can be further improved.

An operating lever 8 is provided that extends to the gap formed between the front edge of the hood 11 and the front bumper 12.The operating lever 8 has a base end 8ε that is the fulcrum of the secondary latch '3, that is, the shaft 13. It is set below the center and is constructed by welding a rod member 8C to an arm portion 8b formed integrally with the secondary latte 3. With this configuration, as shown in FIG. Open the hood 11) and maintain the functional parts in the engine compartment 1
During inspection, etc., if the operator accidentally touches the tip of the operating lever 8 and an external force P' is applied to the operating lever 8 from above as shown in the illustration, the secondary latch 3 A bending load FV centered on the support shaft 13' is applied to the lower end of the secondary latch 3, causing the lower end of the secondary latch 3 to fall down and deform in the direction shown by the chain line in the figure. Since no bending load is applied to the secondary latch 3, it can be avoided from falling and deforming.
The lower end of the holder is tilted and deformed as described above, but since the base plate 1 is close to the direction of the flop, it is restricted by the base plate 1 and cannot be bent and deformed greatly.
