Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grommet used for inserting and fixing a wire harness electric wire and piping in an L-shape into a panel hole of a vehicle or the like. It is related to the improvement of. 2. Description of the Related Art In an automobile or the like, when a wire harness such as a lead wire is pulled out from a panel of a vehicle body, a grommet is attached to a lead hole provided in the panel, and the wire harness is inserted through the grommet. In addition to protecting the wire harness, it is also soundproof and waterproof. Then, it is necessary to prevent the wire harness from interfering with the panel surface or an obstacle, and to improve the penetrability of the wire harness.
Therefore, it may be necessary to bend in an L shape at the panel portion to fix the wire harness. [0003] The wire harness is inserted at
Conventional grommets that are bent and fixed in the shape of a letter include the following. That is, 1) FIGS. 5A and 5B are a plan view and a cross-sectional view taken along line XX of the grommet, respectively. A grommet 1 made of rubber or a soft resin has a base portion 2 and a striated body converging portion 3 which are connected and integrated. A projecting member 4 projects from the upper end of the base 2, and the projecting member 4
Is a hole through which a hole-shaped locking member 5a for locking the striated body converging portion 3 is formed. Referring to FIG. 6, a method of using the grommet 1 will be described. The striated bundle 3 is passed through a hole-shaped locking member 5a provided on the projection member 4 in advance, and the striated bundle 3 is L-shaped bent. Then, the striated body 7 is inserted into the striated body converging section 3 and fixed with a tape or the like.
Reference numeral 8 denotes a panel of an automobile or the like. When the annular groove 2a formed around the elastic base 2 is fitted into the hole 8a formed in the panel 8 by a compressive force, the grommet 1 is locked in a state in which the grommet 1 is in close contact with the panel 8. (See Published Utility Model Publication No. 64-20612). 2) FIG. 7 is a side sectional view showing a state in which another grommet is mounted on the panel penetrating portion. This grommet 15
Is configured by integrally providing a cylindrical body 17 for regulating the direction of the linear body 13 in a rubber grommet main body 16. The cylindrical body 17 is integrally formed in a predetermined curved shape with a synthetic resin in advance, is dimensioned so as to fix the linear body 13, and is inserted into the grommet body 16. Then, the cylindrical body 17 is provided with the grommet 1 by the projections 17 a protruding from the outer peripheral surface of the cylindrical body 17.
6 are locked. Reference numeral 11 denotes a panel, and 12 denotes a penetrating portion (refer to Japanese Utility Model Publication No. Hei 1-150418). [0005] However, the above-mentioned grommet has the following problems. In the grommet 1 described in 1), since the hole-shaped locking member 5a is integrally formed, the range of the L-shaped bending and fixing direction is limited. In addition, since the striated body 7 is inserted into the striated body converging portion 3 in a state where the striated body is bent in an L shape, the operability of the insertion is extremely low. Also in the grommet 16 described in 2), the cylindrical body 17 is
Since it is molded in an L-shape in advance, the workability of inserting the striated body 13 into the cylindrical body 17 and the grommet 1
The workability of attaching 6 is poor. Further, there is a restriction on the bending direction of the grommet 16, and the range of the L-shaped bending fixing direction is limited. As described above, the conventional grommet having an L-shaped bend has poor workability and has limitations on the directionality of the bend. SUMMARY OF THE INVENTION The present invention provides a grommet which has solved the above-mentioned problems, and has a base formed of a thick peripheral wall, and a linear filament bundle formed of a flexible narrow cylindrical portion. A grommet body comprising a series of parts, and a fastener attached to the grommet body, wherein the grommet body is
An annular groove is provided at or near the base portion, and the fastener has an annular portion fitted into the annular groove, and a holding portion for holding the filament bundle portion in a bent state. According to the present invention, after the striated body is inserted into the straight striated body focusing portion, the flexible striated body focusing portion can be bent and held by the fastener. Therefore, the striated body can be easily inserted into the striated body focusing portion. Also, after the grommet is mounted on the mounting plate, the above-described operation of inserting the striated body can be performed. Further, by turning the annular portion of the fastener along the annular groove of the base portion, the position of the holding portion can be changed, and the bending direction of the striated body converging portion can be changed. Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. FIG. 1 is a side view of a rubber grommet main body 21 of one embodiment of a grommet according to the present invention. In the figure, reference numeral 22 denotes a fitting portion with a panel formed of an annular groove;
3 is an annular groove for attaching a fastener, 24 is a striated body converging portion for inserting a striated body, and 25 is an annular base. FIG.
(D) is a back view, a plan view, a side view, and a front view of the fastener 26 formed by bending a linear body made of steel and having a spring property. In the figure, reference numeral 27 denotes a striatum focusing portion 24.
Is a holding portion having a semicircular shape, and 28 is an annular portion. FIGS. 3A to 3C show the grommet main body 2.
1 is a plan view, a side view, and a front view showing a state in which a fastener 26 is attached to 1 and the striated body focusing portion 24 is bent. This attachment is performed as follows. That is, after the linear body 29 made of a wire harness is inserted into the linear striated bundle 24, the holding portion 27 of the fastener 26 is fitted into the striated bundle 24 to obtain a flexible striated body. The focusing unit 24 is bent into an L-shape. Next, the annular portion 28 of the fastener 26 is fitted into the annular groove 23 of the grommet body 21 so as to sandwich the same from both sides, and the fastener 26 is fixed to the grommet body 21. In the present embodiment, since the direction of the holding portion 27 can be changed by rotating the annular portion 28 along the annular groove 23, the bending direction of the striated body focusing portion 24 can also be changed. In addition,
In the present embodiment, the annular portion 28 of the fastener 26 is
As shown in (a) to (d), a resin band such as nylon or polypropylene may be used. In this case, the width of the annular groove 23 is increased according to the width of the annular portion 28 of the fastener 26. As described above, according to the present invention, a grommet main body is provided in which a linear body converging portion comprising a flexible narrow tube portion is connected to a base comprising a thick peripheral wall. And a fastener attached to the grommet body, wherein the grommet body has an annular groove at or near the base, wherein the fastener has an annular portion fitted into the annular groove, and Since it has a holding portion for holding the portion in a bent state, after inserting the striated body into the striated body focusing portion in a straight state, the flexible striated body focusing portion is fixed by a fastener. Since it can be bent and held in the shape of a letter, the striatum can be easily inserted into the striatum collection part,
By turning the annular portion of the fastener along the annular groove of the base, there is an excellent effect that the position of the holding portion can be changed and the bending direction of the striated body converging portion can be changed.
