It was inconvenient because the water drops could get inside the trunk and get wet.

In view of the above, an object of the present invention is to form a water droplet transmission blocking portion at an appropriate position of a lever so that water droplets entering from a key cylinder are dropped on an outer panel of a trunk lid and are not transmitted to a rod.

Means for Solving the Problems The present invention solves the problems described above, and in a lock mechanism of a trunk lid whose end portion reaches the upper surface of a rear bumper, a lever in which the lock mechanism rotates by rotation of a key cylinder. A rod that moves up and down by the rotation of the lever, and a latch that is engaged and disengaged from a striker located inside a weather strip installed on the rear body by rotating by the up and down movement of the rod. A water droplet transmission blocking portion is formed on the upper part of the outer panel of the trunk lid located below the key cylinder so as to prevent water droplets entering from the key hole of the key cylinder from being transmitted. And the inside of the trunk is prevented from getting wet.

Therefore, water droplets that have entered through the key hole of the key cylinder during car washing, etc., are transmitted further along the lever at the water droplet transmission blocking portion formed on the upper part of the outer panel of the trunk lid located below the key cylinder of the lever. Will be prevented and dripping from there. Since the place where the liquid was dropped is on the inner surface of the trunk lid outer panel, the water droplets transmitted to the trunk lid outer panel are perforated at both ends of the trunk lid inner panel located outside the weather strip along the panel. It is guided to the drain hole and discharged.

Embodiment An embodiment of a trunk wetting prevention mechanism according to the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view showing a rear portion of a passenger car, FIG. 2 is a cross-sectional view showing a lock mechanism of a trunk lid, and FIGS. 3 (A), (B) and (C) each show a lock mechanism. It is a perspective view which shows the example of a form of the water droplet transmission prevention part formed in the lever.

In FIG. 1, A is a trunk lid, the end a of which extends to the upper surface of a rear bumper B, and a key is inserted into a key cylinder 1 attached to an outer panel d of the trunk lid and rotated to rotate the trunk lid. The lock mechanism of A is unlocked. The locking mechanism of the trunk lid A is automatically locked by closing the trunk lid A.

 In addition, C in the figure is a tail lamp.

The structure of the lock mechanism of the trunk lid A will be described in detail with reference to the cross-sectional view of FIG. 2. 1 is a key cylinder, 2 is a lever, 3 is a rod, and 4 is a latch. The key cylinder 1 and the latch 4, which are separated due to reaching the upper surface of the rear bumper, are connected by a rod 3. One end of the rod 3 is connected to the key cylinder 1 via the lever 2,
The other end of the trunk lid is located inside the weather strip 6 in the same manner as the striker 5 provided inside the trunk lid weather strip 6 for sealing the trunk lid A in relation to the end a of the trunk lid. It is connected to the latch 4 installed on the inner panel b. Therefore, the lever 2 located between the trunk lid inner panel b and the trunk lid outer panel d
And the rod 3 is provided with a hole c formed in the inner panel b.
To be connected to the latch 4.

When the lock mechanism is unlocked, the lever 2 rotates by the rotation of the key cylinder 1 by the key operation, and the lever 2
Turns the rod 3 connected thereto up and down. Further, the vertical movement of the rod 3 causes the latch 4 that engages with and disengages from the striker 5 provided inside the trunk with respect to the weatherstrip 6 installed on the rear body D for sealing, so that the trunk lid A is locked. The mechanism will be unlocked.

Then, water droplets penetrating the key hole of the key cylinder 1 are transmitted through the lever 2 and the rod 3, and the hole c of the inner panel b is
A water droplet transmission blocking portion that prevents water droplets from being transmitted to the lever 2 so as not to get into the trunk by passing through the trunk.
2a is formed on the upper part of the outer panel d of the trunk lid A located below the key cylinder 1 (near the end near the key cylinder 1). This water droplet transmission blocking portion forms a notch 20a near the key cylinder 1 of the lever 2 as shown in FIG. 3 (A), for example. FIG. 3 (B)
As shown in FIG. 7, the driving bead 21a may be formed on the lever 2 near the key cylinder 1. Alternatively, FIG. 3 (C)
