  By the way, a lock mechanism constituted by a striker and a trunk lid locking device has a structure in which a pop-up lever for urging the trunk lid in the opening direction is added to facilitate opening of the trunk lid when unlocking. ing. Hereinafter, a description will be given with reference to FIG.

  FIG. 11 is a side sectional view showing the structure of a conventional locking device. As shown in FIG. 11, a gate-type striker 23 projects from the rear end panel 21 extending in the vehicle width direction at the rear of the vehicle body so as to be substantially straight along the vehicle body longitudinal direction. A cover plate 19 having a substantially rectangular opening 33 formed at a position corresponding to the striker 23 is attached to the rear end panel 21 so as to have a space S between the rear end panel 21.

  As shown in FIG. 12, a trunk lid 9 is provided above the rear bumper 3 at the rear of the vehicle body to open and close the trunk opening 7 that is opened above and behind the trunk room 5. A front end of the lid upper surface portion 10 of the trunk lid 9 is pivotally attached to the vehicle body by a hinge member 12, and a lock cover 113 is provided at a lower end edge of a substantially central portion in the vehicle width direction of the lid rear surface portion 11. It has been.

  This lock cover 113 has a pair of front end portions 113b and 113b extending and projecting substantially the same length downwardly with an interval in the vehicle width direction, and the striker 23 enters between the pair of front end portions 113b and 113b. A latch (not shown) that is configured as an opening 113a and engages with the striker 23 that has entered the cut opening 113a is incorporated.

  When the latch is unlocked, the pop-up lever 50 that presses the lock cover 113 upward and biases the trunk lid 9 in the opening direction is arranged in the vehicle width direction of the striker 23 (right side in the vehicle width direction in FIG. 11). Adjacent to each other.

  A substantially rectangular flap 143 that opens and closes the opening 33 is pivotally supported on the cover plate 19 in the vehicle width direction on the rear side of the vehicle body. As shown in FIG. 13, when the trunk lid 9 is closed, the upper surface of the flap 143 comes into contact with the front end portions 113b and 113b of the lock cover 113 so that the flap 143 rotates in the space S around the shaft portion 45 on the rear side of the vehicle body. The opening 33 is opened.

  The flap 143 is formed with a slit 147 into which the striker 23 and the pop-up lever 50 enter when the flap 143 is rotated in conjunction with the opening / closing operation of the trunk lid 9 (see FIG. 14).

  Here, during the closing operation of the trunk lid 9, from the time when the front end portions 113b and 113b of the lock cover 113 come into contact with the contact portion 53 of the pop-up lever 50, the striker 23 and the latch are engaged to complete the lock. The amount by which the pop-up lever 50 moves downward during this period is set in advance according to the pressing force required to press the lock cover 113 upward. That is, the pop-up lever 50 is biased so as to be positioned upward by a biasing spring (not shown), and the pressing force that presses the lock cover 113 upward increases as the downward movement amount increases. ing. In the example shown in FIG. 11, the pop-up lever 50 is disposed at a relatively upper position in order to ensure a predetermined movement amount.

  For this reason, the slit 147 formed in the flap 143 is notched greatly in the vehicle width direction so that the striker 23 and the pop-up lever 50 and the flap 143 may enter to prevent the striker 23 and the pop-up lever 50 from entering. There is a problem that the opening area of the slit 147 is increased and the appearance is deteriorated.

  This invention is made | formed in view of this point, The place made into the objective is to suppress the opening area of the slit formed in a flap to the minimum, and to improve appearance.

  In order to achieve the above-described object, the present invention sets the protruding length of one tip portion corresponding to the pop-up lever side of the pair of tip portions of the lock cover to be longer than the other, and arranges the pop-up lever downward. I was able to do it.

  Specifically, the present invention opens and closes a gate-type striker projecting from a rear end panel extending in the vehicle width direction and a vehicle body opening opened at the rear of the vehicle body so as to be substantially straight along the vehicle body longitudinal direction. An opening and closing body that is provided at a lower end of the opening and closing body, and has a pair of tip portions that project downward and spaced apart in the vehicle width direction, and a gap between the pair of tip portions serves as a slit into which the striker enters. The following solution has been taken for an automobile opening / closing body locking device that is configured and includes a lock cover that includes a lock member that engages with the striker that has entered the slit.

That is, the invention according to claim 1 is a pop-up lever that is arranged adjacent to the striker in the vehicle width direction and presses the lock cover upward to urge the opening / closing body in the opening direction when the lock member is unlocked. When,
A cover plate attached to the rear end panel so as to have a space between the rear end panel and having a substantially rectangular opening formed at a position corresponding to the striker;
A substantially rectangular flap that is pivotally supported by the cover plate in the vehicle width direction and that opens and closes the opening of the cover plate by abutting the lock cover when the opening and closing body is opened and closed and rotating in the space. Prepared,
The flap is formed with a slit into which the striker enters when the flap rotates in conjunction with the opening / closing operation of the opening / closing body,
Of the pair of tip portions of the lock cover, the protruding length of one tip portion corresponding to the pop-up lever side is set longer than the other.

  According to a second aspect of the present invention, in the first aspect of the present invention, the opening / closing body has a front end pivotally mounted in the vicinity of the front of the trunk opening of the trunk opening at the rear of the vehicle body, and the lock cover is provided at the rear end. It is a trunk lid that opens and closes the trunk opening.

  According to a third aspect of the present invention, in the first aspect of the invention, the opening / closing body has an upper end pivotally mounted near the upper edge of the tailgate portion opened at the rear of the vehicle body, and the lock cover is provided at the lower end. It is a back door that opens and closes the tailgate portion.

  According to the first aspect of the invention, since the protruding length of one tip portion corresponding to the pop-up lever side among the pair of tip portions constituting the cut opening of the lock cover is set longer than the other, the opening / closing body The pop-up lever can be arranged below the conventional one while ensuring the amount of downward movement of the pop-up lever necessary to obtain a pressing force that pushes the button upward. Thereby, the slit formed in the flap can be made into a shape into which only the striker enters without the conventional shape into which the striker and pop-up lever enter. For this reason, the opening area of a slit can be made small and appearance can be improved.

  According to the second aspect of the present invention, the front end is pivotally mounted in the vicinity of the front of the vehicle body of the trunk opening opened at the rear of the vehicle body, and the trunk lid is provided with the lock cover at the rear end to open and close the trunk opening. The present invention can be applied to a motor vehicle provided.

  At this time, the lower end of the lock cover 13 abuts against the abutting portion 53 of the pop-up lever 50 and pushes down, and the lever portion 51 of the pop-up lever 50 rotates the rotating shaft 52 against the urging force of the urging spring 54. It rotates so that the contact portion 53 is positioned below the center.

  When the trunk lid 9 reaches the closed position, the striker 23 is inserted into the cut opening 13a of the lock cover 13 and pushes the latch 81. The latch 81 pushed by the striker 23 rotates about the rotation shaft 83, the claw portion 81a engages with the striker 23, and the trunk lid 9 is locked to the vehicle body side to be locked.

  On the other hand, when the trunk lid 9 is opened, the engagement between the claw portion 81a of the latch 81 and the striker 23 is released by a lock release mechanism (not shown). When the lock is released, the urging force of the urging spring 54 locked to the pop-up lever 50 causes the lever portion 51 to rotate clockwise in FIG. Moves upward and raises the trunk lid 9 upward. At this time, the flap 43 is urged by the torsion coil spring 65 to close the opening 33 of the cover plate 19 so that the striker 23 can be seen only from the slit 47.
