Abstract

In a lid locking device of the present invention, a first rod constituting portion at the front end of a rod is eccentrically located on a side of the rod which is a side spaced away from the lid at a forward extending region of the second rod constituting portion linearly movably supported at the tip cylindrical portion. Therefore, even where an engagement protrusion piece presses a side close to the lid of a tip swelling face of the first rod constituting portion, the device of the present invention is able to receive an axial force F derived from pressing force at a position closer to the central axis of the second rod constituting portion and also decrease in resistance on operation of closing the lid compared to a conventionally structured device.

First claim

What is claimed is:

1. A lid locking device, comprising:
a housing fixed on a vehicle and provided with a support hole having a circular shape;
a rod which is linearly movably assembled to the housing and urged forward and a front end portion thereof is, in a process of closing a lid of the vehicle, pressed by a locking engaging portion provided on the lid, moving backward to an unlocked position, then, moving forward to a locking position and making an engagement with the locking engaging portion, thereby locking the lid in a closed state;
a supporting rod portion which is provided at an intermediate portion of the rod in an axial direction and linearly movably supported on the support hole, the supporting rod portion having a circular cross section;
an engagement rod portion which is provided as the front end portion of the rod, thinner than the supporting rod portion, eccentrically located on a side of a forward extending region of the supporting rod portion which is spaced away from the lid, and at least partially overlapped with the central axis of the supporting rod portion;
an opposed flat face provided in the housing and opposed from a lid side to a side face of the rod at a position more rearward than the supporting rod portion; and
a slide-contact protruding strip protruding from the side face of the rod located more rearward than the supporting rod portion so as to contact the opposed flat face and extending in a direction parallel to the opposed flat face and also perpendicular to the axial direction of the rod.

2. The lid locking device according to claim 1 , further comprising:
a hole-inner face opposing portion which is provided at the engagement rod portion and enters into the support hole, and adjoins or comes in contact with an inner face of the support hole.

3. The lid locking device of claim 2 , further comprising:
the supporting rod portion and the engagement rod portion being circular in cross section; and
a diameter reducing portion in which a front end portion of the supporting rod portion is gradually reduced in diameter toward an end of the engagement rod portion.

4. The lid locking device according to claim 2 , further comprising:
a tip swelling face which is provided at the front end of the engagement rod portion, inclines in relation to the axial direction of the engagement rod portion so as to face to an outer face of the vehicle and is curved outward.

5. A lid locking mechanism composed of the lid locking device according to claim 2 and the lid, the lid locking mechanism, comprising:
in a process of closing the lid, the locking engaging portion pressing the engagement rod portion so as to pass through an axial intersection with which the central axis of the supporting rod portion intersects on the front end face of the engagement rod portion.

6. The lid locking device according to claim 3 , further comprising:
the diameter reducing portion is annular and surrounds an entire base end portion of the engagement rod portion.

7. The lid locking device according to claim 3 , further comprising:
a tip swelling face which is provided at the front end of the engagement rod portion, inclines in relation to the axial direction of the engagement rod portion so as to face to an outer face of the vehicle and is curved outward.

8. The lid locking device according to claim 6 , further comprising:
a tip swelling face which is provided at the front end of the engagement rod portion, inclines in relation to the axial direction of the engagement rod portion so as to face to an outer face of the vehicle and is curved outward.

9. The lid locking device of claim 1 , further comprising:
the supporting rod portion and the engagement rod portion being circular in cross section; and
a diameter reducing portion in which a front end portion of the supporting rod portion is gradually reduced in diameter toward an end of the engagement rod portion.

10. The lid locking device according to claim 9 , further comprising:
the diameter reducing portion is annular and surrounds an entire base end portion of the engagement rod portion.

11. The lid locking device according to claim 9 , further comprising:
a tip swelling face which is provided at the front end of the engagement rod portion, inclines in relation to the axial direction of the engagement rod portion so as to face to an outer face of the vehicle and is curved outward.

12. A lid locking mechanism composed of the lid locking device according to claim 9 and the lid, the lid locking mechanism, comprising:
in a process of closing the lid, the locking engaging portion pressing the engagement rod portion so as to pass through an axial intersection with which the central axis of the supporting rod portion intersects on the front end face of the engagement rod portion.

13. The lid locking device according to claim 10 , further comprising:
a tip swelling face which is provided at the front end of the engagement rod portion, inclines in relation to the axial direction of the engagement rod portion so as to face to an outer face of the vehicle and is curved outward.

14. A lid locking mechanism composed of the lid locking device according to claim 10 and the lid, the lid locking mechanism, comprising:
in a process of closing the lid, the locking engaging portion pressing the engagement rod portion so as to pass through an axial intersection with which the central axis of the supporting rod portion intersects on the front end face of the engagement rod portion.

15. The lid locking device according to claim 1 , further comprising:
a tip swelling face which is provided at the front end of the engagement rod portion, inclines in relation to the axial direction of the engagement rod portion so as to face to an outer face of the vehicle and is curved outward.

16. A lid locking mechanism composed of the lid locking device according to claim 15 and the lid, the lid locking mechanism, comprising:
in a process of closing the lid, the locking engaging portion pressing the engagement rod portion so as to pass through an axial intersection with which the central axis of the supporting rod portion intersects on the front end face of the engagement rod portion.

17. A lid locking mechanism composed of the lid locking device according to claim 1 and the lid, the lid locking mechanism, comprising:
in a process of closing the lid, the locking engaging portion pressing the engagement rod portion so as to pass through an axial intersection with which the central axis of the supporting rod portion intersects on the front end face of the engagement rod portion.

18. The lid locking device according to claim 1 , further comprising:
a protrusion portion protruding to be parallel to the opposed flat face, the protruding portion forming the rod at the position more rearward than the supporting rod portion, and the slide-contact protruding strip is extending from the side face of the rod over to a side face of the protrusion portion.

19. The lid locking device according to claim 1 , wherein the slide-contact protruding strip has a semi-circular arc cross section.

20. A lid locking device, comprising:
a housing which is arranged so as to be fixed on a vehicle and provided with a support hole having a circular shape;
a rod which is linearly movably assembled to the housing and urged forward and a front end portion thereof is, in a process of closing a lid of the vehicle, pressed by a locking engaging portion provided on the lid, moving backward to an unlocked
