A second member comprising two or more second snap hooks extending vertically upward from the second base portion having a piece, and a second insertion hole portion opened in the vertical direction to the second base portion; The first snap hook is inserted into and engaged with the second insertion hole, and is prevented from falling in the horizontal direction. The second snap hook is inserted into the first insertion hole and is horizontally inserted. With the open lever hole periphery or the insertion hole part being restricted from falling It is to be configured to focus.

  In this case, either the first snap hook or the second snap hook may be fitted in a notch provided in the open lever hole in a direction orthogonal to the engagement direction of the snap hook. .

  The second member may be provided with an urging portion that protrudes slightly from the upper surface of the second base and contacts the lower surface of the open lever at a position spaced outward from the second base.

  Also, the leading edge of the first hinge-shaped plate extending in the horizontal direction from the first base of the first member and the leading edge of the second hinge-shaped plate extending in the horizontal direction from the first base of the second member. And should be integrated.

  According to the present invention, the first member is provided with the first insertion hole for restricting the second snap hook provided in the second member to fall in the horizontal direction, and the second member is provided in the first member. Since the first snap hook is configured to include the second insertion hole that restricts the first snap hook from falling in the horizontal direction, the first and second snap hooks can be prevented from falling in the horizontal direction. Therefore, a highly reliable bush can be provided.

  Further, the first snap hook or the second snap hook is configured to fit into the cutout portion in a direction orthogonal to the engagement direction with the open lever, whereby the first snap hook with respect to the open lever hole portion. Alternatively, the second snap hook can be positioned. Therefore, a more reliable bush can be provided.

  Preferably, if the second member is provided with an urging portion that protrudes slightly from the upper surface of the second base and contacts the lower surface of the open lever at a position spaced apart from the second base in the outward direction, the open lever of the second member Can be positioned. Therefore, it can be set as the bush which improved quality.

  Desirably, if the tip pieces of the first and second hinge-shaped plates extending in the horizontal direction from the first base and the second base are integrated, not only can the number of parts be reduced, It is possible to improve the ease of assembly. Therefore, the bush can be further improved in quality.

  A first embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the bush 20 is configured at a location where an open rod 80 (rod) described later of the door lock device 100 and an open lever 10 are connected.

  The open rod 80 is connected to an outside handle (not shown) provided outside the vehicle (not shown). The open rod 80 is formed by bending a metal rod-shaped member having a diameter smaller than the diameter of the open lever hole portion 11 described later. As shown in FIG. 2, the open rod 80 is opened by a connecting portion 80 a held at one end by the outside handle of the vehicle, an insertion portion 80 b inserted through the open lever hole portion 11, and the operating force of the outside handle.

The first snap hook 32 is also provided at a symmetrical position with respect to the hole 310.

  As shown in FIGS. 9 and 10, the second member 40 includes a second base 41 formed in a disc shape and two second snap hooks 42 erected vertically from the surface 41 a of the second base 41. It is configured.

  The second base 41 is provided with a second insertion hole 44 having a diameter larger than that of the hole 310. The second insertion hole 44 has a notch 420 into which the two first snap hooks 32 provided in the first member 30 are inserted and engaged. Further, the second insertion hole 44 extends from the inner peripheral surface formed by providing the second insertion hole 44 of the second base 41 toward the center from the symmetrical position on the inner diameter side of the second insertion hole 44. A cylindrical cylindrical portion 410 having a hole portion 411 having substantially the same diameter as the hole portion 310 through one arm portion 410a and into which the open rod 80 can be inserted is integrally provided. The notch 420 is notched further to the outer peripheral side of the second base 41 than the abutting surface 420a with which the first engaging piece 33 of the first snap hook 32 abuts, and the abutting surface 420a. The engaging portion 420b is engaged with the engaging portion 420b. The notch 420 is also provided at a symmetrical position with respect to the tubular portion 410. The distance between the notches 420 is set to be slightly smaller than the distance between the first engagement pieces 33 of the first snap hook 32.

  The second snap hook 42 is formed on a part of the outer peripheral surface of the second base portion 41, a contact surface 42 a that contacts the notch portion 12 of the open lever hole portion 11 from the back surface 41 b to the front surface 41 a, and a tip protruding from the surface 41 a. A hook-like second engaging piece 43 whose portion protrudes toward the outer peripheral side of the second base 41 is integrally formed. The second engagement piece 43 is provided at a symmetrical position with respect to the hole 411 of the cylindrical portion 410. The distance between the second engagement pieces 43 of the two second snap hooks 42 is set to be slightly larger than the distance between the two notches 12 of the open lever hole 11.

  Next, the procedure for assembling the bush 20 of this embodiment to the open lever 10 will be described.

  First, two second snap hooks 42 of the second member 40 are inserted through the notch 12 of the open lever hole 11 of the open lever 10 of FIG. The second engagement piece 43 at the tip end of the hook 42 is inserted while being bent toward the center of the open lever hole 11. The second engaging piece 43 returns to its original state and engages with the surface 10a of the open lever 10 by the restoring force of the resin at the moment when it completely passes through the notch 12, as shown in FIG. At this time, the contact surface 42a of the second snap hook 42 and the notch 12 are in contact with each other.

  Subsequently, the two first snap hooks 32 of the first member 30 are inserted into the open lever hole 11 from the front surface 10a to the back surface 10b of the open lever 10, and the second base 41 assembled on the back surface 10b side is contacted. When the first engagement piece 33 is brought into contact with the contact surface 420a and inserted from the front surface 41a to the back surface 41b side of the second base 41, the distance between the two first engagement pieces 33 is as follows. Since the distance is set to be greater than the distance between the first engagement pieces 33, the first engagement pieces 33 are inserted while being bent toward the center side of the first base portion 31. When the insertion of the first engagement piece 33 into the notch 420 proceeds, the first engagement piece 33 gets over the contact surface 420a. At that moment, the first engaging piece 33 bent toward the center of the first base portion 31 returns to its original state and engages with the engaging portion 420b as shown in FIG. 12 by the restoring force of the resin.

  As described above, the first snap hook 32 is in contact with the outer peripheral surface of the cylindrical portion 410 by assembling the bush 20 including the first member 30 and the second member 40 to the open lever 10. It becomes. Further, the second snap hook 42 is in contact with the inner peripheral surface of the first insertion hole 34 of the first base 31. Therefore, it is possible to prevent so-called “falling” in which the first snap hook 32 and the second snap hook 42 fall to the center side of the first base portion 31 and the second base portion 41.

  Here, “falling down” will be described using a general snap hook as an example. When the operating portion 80c of the open rod 80 presses the bush by operating the outside handle, the engagement piece of the snap hook receives a load toward the center side of the bush. And if a snap hook is used for many years, the engagement force of an engagement piece will decrease by a secular change by the fall of the intensity | strength etc. of resin. Thus, the engagement piece that continues to receive the load toward the bush center side cannot hold the engagement and falls down to the bush center side.

  Next, a second embodiment according to the present invention will be described below with reference to FIGS.

  The members having the same mode as in the first embodiment will be described with the same drawing numbers as in the first embodiment.

  As shown in FIGS. 13 to 16, the bush 520 of the second embodiment has a second arm portion 542 extending from the outer peripheral surface of the second base portion 541 of the second member 540, and a ring-shaped annular portion 543 (attached). Formation). Since the annular portion 543 protrudes slightly from the surface 541a of the second base portion 541, the annular portion 543 is in contact with the back surface 10b of the open lever 10 with a biasing force as shown in FIG. About each other member, since it is the aspect similar to the above-mentioned 1st Example, description is abbreviate | omitted here.

  As described above, if the bush 520 further including the annular portion 543 is configured in addition to the aspect of the first embodiment, the engaging force of the second member 540 with respect to the open lever 10 can be further strengthened. In the present embodiment, an example in which the ring-shaped annular portion 543 is disposed at a position separated from the outer periphery of the second base portion 41 has been described. However, the annular portion 543 is biased against the back surface 10b of the open lever 10. It is not always necessary to have a ring shape, and for example, an L-shaped protruding piece may be used.

  Next, a third embodiment according to the present invention will be described below with reference to FIGS.

  As shown in FIGS. 17 to 20, the bush 620 of the third embodiment is a modification of the bush 20 of the first embodiment, and extends from the outer peripheral surface of the first base portion 31 of the first member 30. One hinge-shaped plate 632 and a second hinge-shaped plate 642 extending from the second base 41 of the second member 40 are integrally formed. The other members are the same as those in the first embodiment, and the description thereof is omitted here.

  The third embodiment can also be applied to the bush 520 of the second embodiment as shown in FIG. In this case, the second hinge plate 642 may be integrally formed from the outer peripheral surface of the annular portion 543.

  Here, when the bush 620 of the third embodiment is assembled to the open lever 10, the first member 30 and the second member 40 are arranged on the front surface 10a side and the back surface 10b side with respect to the open lever 10, respectively. The open lever 10 may be sandwiched by pressing the front surface 31a of the first base 31 of the one member 30 and the back surface 41b of the second base 41 of the second member 40.

  Subsequently, the operation of the present embodiment will be described below.

  When the outside handle is operated, the open rod 80 that operates in conjunction with the outside handle operates in a downward direction (arrow direction) in FIG. By the downward operation of the open rod 80, the operation portion 80c presses the surface 10a of the open lever 10 downward in the drawing of FIG. The open lever 10 pressed by the actuating portion 80c can be opened by opening the door lock device 100 by rotating about a rotating shaft (not shown).

  As described above, according to the present embodiment, the first insertion hole 34 that regulates the horizontal snapping of the second snap hook 42 provided on the second member 40 to the first member 30 is provided, Since the second insertion hole 44 for restricting the horizontal collapse of the first snap hook 32 provided on the first member 30 to the second member 40 is provided, the first and second snap hooks 32, 42 can be prevented from falling down in the horizontal direction. Therefore, a highly reliable bush can be provided.

  Furthermore, either the first snap hook 32 or the second snap hook 42 is configured to fit into the notch portion in a direction orthogonal to the engagement direction with the open lever 10, thereby preventing the open lever hole portion 11. The first snap hook 32 or the second snap hook 42 can be positioned. Therefore, the bush 20 with higher reliability can be provided.

The second member 40 can be positioned with respect to the open lever 10. Therefore, it can be set as the bush which improved quality.

  Desirably, if the tip pieces of the first and second hinge plates extending in the horizontal direction from the first base portion 31 and the second base portion 41 are integrated, the number of parts can be reduced. Therefore, it is possible to improve the assembly. Therefore, the bush can be further improved in quality.

  Further, the first base 30 and the first base 31 and the second base 41 of the second member 40 of the present embodiment are formed in a disc shape, but need not be formed in a disc shape, for example, a rectangular parallelepiped. You may form in a shape.

  In the present embodiment, the second engagement piece 43 provided at the distal end portion of the second snap hook 42 provided in the second member 40 has the notch portion 12 provided in a part of the open lever hole portion 11. However, the present invention is not limited to this. For example, the second snap hook 42 is further extended in the direction of the surface 41a of the first base 41, and the second engagement piece 43 is formed. May be configured to engage with the first base 31.

  As for the assembling procedure, the operator can work in a visible state from above by assembling the first member 30 after first assembling from the second member 40 below the open lever 10 into the open lever hole 11. So assembly is good.
