However, in the conventional engine cover lock mounting structure, the engine cover 5
In order to secure a sufficient force to close the lever and to make the operating force of the lever 8 at the time of lock operation appropriate,
It is necessary to set the mounting position (upper and lower positions) with respect to the inclined surface 1a of the engine cover lock 6 at an appropriate position. For this reason, while visually checking the lever 8 to the position C in FIG. This is a work of supporting, positioning the base 9, and tightening the bolts 22, and there is a problem that workability is poor and time and labor are required.

That is, the inclined surface 1a is caused by an error in the parts of the engine cover 5 and the weather strip 14 and an assembly error.
On the other hand, when the position of the hook 7 varies and the mounting position of the engine cover lock 6 is low, the lever 8 is located above the position of the hook 7 (position A in FIG. 6), and the lever 8
Therefore, a strong force is required to fix the engine cover 5. Further, when the mounting position of the engine cover lock 6 on the inclined surface 1a is high, the position of the lever 8 is higher than the hook 7 (position B in FIG. 6), and the force for fixing the engine cover 5 becomes weak.

The present invention has been made in view of such a problem, and improves the workability of installing the engine cover lock, and the force of pulling the lever and the force of locking the engine cover when the engine cover is closed and locked. It is an object of the present invention to provide an engine cover lock mounting structure capable of setting the desired value as desired.
