As shown in FIG. 1, the hood lock device 20 faces the entrance 21a of the main striker 13 formed in the housing 21, and a main latch member 22 and a locking member 23 for restraining the main latch member 22 are pivotally connected to the housing 21. has been done. An operating cable 24 extending into the vehicle interior is connected to the locking member 23.

An auxiliary latch member 30 is provided on one side of the housing 21.
is pivotally mounted via a pivot 31, and the hood 12
A striker portion 14 (shown in FIG. 2) is formed in the holder to which the auxiliary latch member 30 engages and disengages. The pivot shaft 31 of the auxiliary latch member 30 is located on the line of entry of the striker portion 14.

The auxiliary latch member 30 is biased clockwise in the figure by a biasing spring 30a, and is normally in contact with a stopper 15 projecting from the housing 21. The auxiliary latch member 30 has a manual operation handle 33 at the end of an operation arm 32 that extends substantially horizontally, and an engagement arm 34 that extends upward offset from the advancing direction of the striker portion 14. A striker engaging piece 35 is pivotally attached to the tip thereof via a pin 35a.

The striker engaging piece 35 consists of a locking claw part 36 and a stopper piece 37, and the locking claw part 36 has a hood 1 attached thereto.
Guide inclined surface 38 that the striker portion 14 of No. 2 comes into contact with
is formed. The striker engagement piece 35 is connected to the biasing spring 3 stretched between the striker engagement piece 35 and the base of the engagement arm 34.
9 in the counterclockwise direction in FIG.
Normally, the stopper piece 37 is in contact with the engagement arm 34 and the engagement claw portion 36 is held in a position protruding in a direction substantially perpendicular to the advancing direction line of the striker portion 14 on the side of the tip end of the engagement arm 34. ing. Also,
Pin 35a which is a pivot shaft of striker engagement piece 35
is offset with respect to the advancing direction line of the striker portion 14. Note that the biasing force of the biasing spring 39 is set smaller than the biasing force of the biasing spring 30a.

Next, the action will be explained.

When closing the hood 12, the auxiliary latch member 3
0, the engagement arm 34 is normally upright as shown in FIG.
The tip is held in a position that protrudes laterally. When the hood 12 is close to being fully closed, the striker portion 14 comes into contact with the guide slope 38 of the locking claw portion 36 of the striker engaging piece 35 and pushes it. It is rotated clockwise against the biasing force, and as shown in FIG. 2, the locking claw portion 36 retracts from the side of the engagement arm 34, and the striker portion 14 advances without resistance. When the striker part 14 avoids the tip of the locking claw part 36,
The state shown in FIG. 1 is restored by the biasing force of the biasing spring 39, and the striker portion 14 is restrained from coming out.

When the striker part 14 tries to come out, it engages with the locking claw part 36 of the striker engaging piece 35 and tries to rotate, but the striker engaging piece 35 does not rotate and the auxiliary latch Since the pivot 31 of the member 30 is located on the advancing direction line of the striker portion 14, no rotational force is generated in the auxiliary latch member 30, and the striker portion 14 is reliably restrained.

Before and after the striker portion 14 is locked with the striker engagement piece 35, the main striker 13 pushes the main latch member 22, and the main latch member 22 rotates while restraining the main striker 13, thereby locking the locking member 2.

When opening the hood 12, the operating cable 24 is pulled from inside the vehicle to activate the locking member 23 and release the main latch member 22. When the main latch member 22 is released, it rotates clockwise due to the elastic force of a spring (not shown), pushing up the main striker 13 and opening it.

Even if the main striker 13 is released, the striker portion 14 is still attached to the striker engaging piece 3 of the auxiliary latch member 30.
5, the hood 12 can only be opened slightly but cannot be fully opened. Therefore, when a finger is placed on the manual operation handle 33 and the auxiliary latch member 30 is rotated counterclockwise against the biasing force of the biasing spring 30a, the striker engaging piece 35 is also rotated, as shown in FIG. As shown in the figure, the hood 12 can be opened wide by moving from the position indicated by the two-dot chain line to the position indicated by the solid line to release the restraint of the striker portion 14, and then lifting the hood 12. When the auxiliary latch member 30 is released from the manual operation handle 33, the auxiliary latch member 30 moves to the first position.
Return to the position shown in the figure.

The auxiliary latch member may be provided on either the hood side or the vehicle body side, and may be separate and independent from the main latch mechanism.

"Effect of the invention" According to the automobile hood lock device according to the invention, the striker engaging piece is pivotally attached to the auxiliary latch member, and when the hood is closed, only the striker engaging piece swings to lock the striker. Because of this, the resistance when locking is low and it can be operated easily, and since the impact is small, it will not wear out or rust.

Even if the striker portion tries to come out, no rotational force is generated in the auxiliary latch member, so the striker portion is reliably restrained, resulting in high safety.
