In addition, the outer diameter of the wire harness at the same installation location varies, and there are many locations where the wire harness cannot be fixed due to looseness or sagging depending on the surrounding conditions. Fasteners had to be prepared and installed. However, using different types of fasteners may cause quality defects due to incorrect products, and preparing multiple types of fasteners requires a large amount of man-hours for parts arrangement and parts management. It is uneconomical, and if the current fasteners are to be standardized, the maximum harness diameter must be set, and if the harness diameter is small, other parts must be inserted. There were defects that caused quality problems such as abnormal noise generation and interference.

The present invention has been made in order to eliminate the above-mentioned conventional drawbacks, and aims to provide a fastener that can cope with variations in the outer diameter of the wire harness and that can be fixed without play. It is.

When the first locking piece 39 is in an upright state, a rotation stopper piece 44 is integrally formed so as to be substantially parallel to the arcuate surface of the receiving portion 4 . In addition, 45 is the first
This is a convex portion formed on the inner surface of the locking piece 39. The locking portion 37 formed in this manner is rotatably provided via the thin wall portion 36 and engages the engagement groove 3 of the presser lid 27.
3 is provided with a first locking piece 39 and a second locking piece 41 that can be selectively locked.

Next, the operation and effect of the present embodiment configured as described above will be explained. The fastener 3 of this embodiment is engaged with the mounting hole 2 penetrated through the steel plate body 1 of a vehicle etc., and the wire harness W is disposed therein. It is made of synthetic resin, etc., and has a locking leg 6 that elastically locks to the mounting hole 2 on the outer surface of the approximately semicircular receiving portion 4, and a predetermined locking leg 6 for this locking leg 6. A pair of presser legs 15 having elastic properties are provided in the shape of open legs at an angle α, and a rising piece 24 extending upward with a predetermined length is provided at one end of the receiving portion 4. A presser cover 27 having an engagement groove 33 at the end is provided on the upper end side of the rising piece 24 so as to be rotatable above the receiving portion 4, and a presser foot is provided at the other end of the receiving portion 4. The locking portion 37 having the first locking piece 39 and the second locking piece 41 is rotated through the thin portion 36 at a predetermined angle β so that it can be selectively engaged with the locking groove 33 at the tip of the lid 27. An elastically deformable wire harness holding piece 22 is movably provided on the inner surface near the rising piece 24 provided on the receiving part 4 and bulges in a direction toward the locking part 37.
It has been established. Therefore, for example, in the case of the wire harness W ₁ having a large outer diameter, the first locking piece 39 is disposed opposite to the _rising piece 24 as shown in FIG. Place it on. Thereafter, the retaining lid 27 is rotated upwardly around the thin wall portion 26 of the receiving portion 4, and the engaging groove 33 formed at the end thereof is engaged with the first locking piece 39, thereby securing the wire harness. W ₁ can be fixed. In this fixed state, the wire harness W ₁ is held down by the holding lid 27, but since the wire harness holding piece 22 is provided inside the receiving part 4, this holding piece 22 is elastically deformed by the wire harness W ₁ . However, due to this repulsive force, the engagement groove 33 and the first locking piece 39 are firmly engaged, and the wire harness _W1 can be firmly fixed to prevent rattling. Further, the locking portion 36 caused by the thin wall portion 36, that is, the first locking piece 39, can be prevented from wobbling by the rotation prevention piece 44. When the locking leg 6 vertically disposed on the receiving portion 4 is inserted into the mounting hole 2 of the steel plate body 1 and pressed, the locking legs 10, 10 of the locking leg 6 are attached to the central axis by the inner edge of the mounting hole 2. At the same time, the tips of the presser legs 15, 15 formed on the receiving portion 4 are brought into contact with the upper surface of the steel plate body 1. Further, when pressed, the presser legs 15, 15 are elastically deformed, and the locking legs 10, 10 are elastically restored at the same time as they pass through the mounting holes 2, and the shoulder portions 11 come into contact with the lower surface side of the steel plate body 1. The neck portions 14, 14 are brought into contact with the inner edges of the mounting hole 2, and the locking leg portion 6 is elastically engaged with the mounting hole 2, while being firmly engaged with the mounting hole 2 due to the repulsive force of the holding legs 15, 15. It will be worn. In addition, this presser foot leg 1
5 and 15 are elastically deformed as shown in the figure, so that variations in the plate thickness t of the steel plate body 1 can be coped with.

Next, in the case of the wire harness W ₂ having a small outer diameter, after placing the wire harness W ₂ on the receiving part 4, push the lever 43 and move the locking part 37 to the thin part 36.
When the second locking piece 41 is arranged opposite to the rising piece 24, the first locking piece 39 also serves as a holding piece for the wire harness _W2 as shown in the figure.
Press it toward the holding piece 22 side. Thereafter, by engaging the second locking piece 41 with the engagement groove 33 of the presser cover 27, the wire harness _W2 can be firmly fixed without wobbling. In this case, the repulsive force of the holding piece 22 presses the wire harness W ₂ against the first locking piece 39 to connect the second locking piece 41 and the engagement groove 3.
The wire harness W ₂ can be fixed by acting on the wire harness W 3 to prevent it from coming off. in this way,
The first part of the locking part 37 is
Since the locking piece 39 and the second locking piece 41 are provided so that they can be selectively engaged, even if there is a change in the outer diameter of the wire harness, it can be dealt with very easily and it can be fixed without wobbling. It is possible.

The present invention is a fastener made of synthetic resin, etc., which is attached to a mounting hole penetrated through a steel plate body of a vehicle, etc., for arranging a wire harness, etc. is provided with a locking leg that elastically locks to the mounting hole, and a pair of presser legs that have elasticity and are spread apart at a predetermined angle with respect to the locking leg, and
A rising piece extending upward with a predetermined length is provided at one end of the receiving portion, and a presser cover having an engagement groove at the end is provided on the upper end side of the rising piece through a thin wall portion. The receiving part is provided so as to be rotatable upward, and the other end of the receiving part has a plurality of locking pieces arranged at a predetermined angle so as to be selectively engageable with the engagement groove at the tip of the presser cover. The locking portion is rotatably provided via the thin wall portion, and an elastically deformable restraining piece is provided on the upright, offset inner surface of the receiving portion, and is elastically deformable and bulges out in a direction toward the locking portion. It is structured as follows. Therefore, since a pair of elastic holding legs are provided at a predetermined angle with respect to the locking legs, variations in the thickness of the steel plate body can be absorbed and the locking can be achieved. In addition, a holding piece is provided inside the receiving part in a bulging shape, and a locking part having a plurality of locking pieces is provided at one end of the receiving part so as to be rotatable through the thin wall part. Together with this, it is possible to cope with variations in the outer diameter of the wire harness, etc., increasing its versatility, and the elastic restoring force of the holding piece allows the wire harness, etc. to be firmly pressed and fixed without wobbling at all times. Therefore, it is an extremely practical idea as a fastener for wire harnesses, etc.
