DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting hole stopper suitably used for binding or positioning a harness or the like in an engine room of an automobile, for example.

[0002]

2. Description of the Related Art As this kind of mounting hole stopper, for example, a plastic stopper as shown in FIGS. 21 and 22 is known.

[0003] This mounting hole stopper is composed of a flexible band 1 and an insertion opening 2 through which the band 1 cannot be pulled out.
An anchor 5 to be inserted into the mounting hole 4 is provided in the wire binding portion 3 provided with: a pair of leg pieces 5a, 5a; And a pair of engaging claws 5b, 5b bent at an acute angle. The engaging claws 5b, 5b are shorter than the leg pieces 5a, 5a.

When the anchor 5 of the mounting hole stopper is inserted into the mounting hole 4, as shown in FIG.
b is pushed inward and elastically deforms so that the included angle with the leg pieces 5a, 5a becomes smaller, while the leg pieces 5a, 5a pass through the mounting hole 4 in contact with each other, and the engaging claws 5b, 5b After passing through the mounting hole 4, the engagement claws 5b, 5 as shown in FIG.
b is resiliently restored to the original state, and their ends engage the peripheral edge 4a of the mounting hole 4, so that this stopper is attached so that it cannot be pulled out.

[0005]

However, the engaging claws 5b, 5b of the anchor 5 are different from those of the conventional mounting hole stopper.
Are shorter than the leg pieces 5a, 5a, when the anchor 5 is inserted into the mounting hole 4, the leg pieces 5a, 5a of the anchor 5 are pushed inward and come into contact with each other, and the engaging claw 5
b, 5b and the leg pieces 5a, 5a are elastically deformed so as to reduce the included angle, and the tips of the engaging claws 5b, 5b strongly press the inner peripheral surface 4b of the mounting hole 4, so that a large insertion force is required. ,
In particular, it is difficult to insert into a small-diameter mounting hole. For this reason, there is a large restriction on the size of the mounting hole to which the mounting hole stopper can be mounted, and it has not been possible to mount the mounting hole to a wide variety of mounting holes from a large hole to a small hole.

When the anchor 5 is inserted into the mounting hole 4 as shown in FIG. 22, the wire binding portion 3 and the engaging claws 5b,
If the distance from the tip of the attachment hole 5b is larger than the thickness of the peripheral portion 4a of the attachment hole 4, the attachment hole stopper will rattle, and conversely, the wire binding portion 3 and the tip of the engagement claws 5b, 5b. When the interval is smaller than the thickness of the peripheral portion 4a of the mounting hole 4, there is a problem that the anchor 5 cannot be inserted and the mounting hole stopper cannot be mounted.

The present invention has been made in view of the above circumstances, and it is possible to insert an anchor into a mounting hole with a relatively small insertion force and mount the anchor. It is an object of the present invention to provide an attachment hole stopper that can be attached to an attachment hole.

It is another object of the present invention to provide a mounting hole stopper which can bind or position a wire such as a harness in various forms.

[0009]

A fastener for a mounting hole according to the present invention has an anchor which is inserted into the mounting hole, and the anchor is formed by an elastically deformable branch portion and a distal end of the branch portion. Having an elastically deformable engaging claw folded at an acute angle,
The tip of each engaging claw projects beyond the branch point of the branch.

In this mounting hole stopper, when the engaging claw is inserted into the mounting hole, the engaging claw and the branch portion are pushed inward until the branch point of the branching portion passes through the mounting hole, and the included angle between the two is formed. Is elastically deformed so as to be smaller, so that the tip of the branching portion comes into contact and is inserted.However, when the branching point passes through the mounting hole and pushes the engaging claw inwardly, it acts on the tip side of the engaging claw. The branch portion is elastically expanded to both sides and inserted. Therefore, until the branch point passes through the mounting hole, the pressing force of the engaging claw against the mounting hole gradually increases as the included angle between the engaging claw and the branch portion decreases, but after the branch point passes through the mounting hole. Since the pressing force hardly increases, the anchor can be inserted with a relatively small insertion force. Then, when the engaging claw passes through the mounting hole, the engaging claw is restored to its original state by its elasticity, and the tip of the engaging claw is engaged with the peripheral portion of the mounting hole.

It is preferable that the mounting hole stopper according to the present invention has an elastically deformable pressing piece facing the tip of each of the engaging claws. In such a configuration, when the tip of the engaging claw engages with the peripheral edge of the mounting hole as described above, the peripheral edge of the mounting hole is elastically held by the pressing piece and the engaging claw. The stopper for holes is attached without looseness, and even if the thickness of the peripheral edge of the mounting hole changes within the range where the elastic deformation of the retainer is allowed, the retainer is elastically deformed and attached correspondingly Become.

In the present invention, various elements useful for binding or positioning the wire are connected to the anchor. Specific examples of those elements are listed below. (1) A pair of opening and closing pieces for opening and closing the loop section are provided at a pair of divided ends formed by dividing one portion of a loop section surrounding the wire, and engagement for connecting the opening and closing pieces is provided. A wire binding piece having a mechanism (each embodiment in FIGS. 1 to 9).
