2. Description of the Related Art A conventional method for fixing a filament of this kind will be described with reference to FIG. In the figure, reference numeral 1 is a housing, and a through hole 2 having a predetermined diameter is opened in the housing 1. On the other hand, in the drawing, reference numeral 3 denotes a bush, which has an inner cylindrical portion 4 and an outer peripheral portion 5 which is formed in a tapered shape having an outer periphery having a diameter smaller than that of the through hole 2. A collar portion 6 is provided at the rear end portion. Further, in the figure, 7 is a cap having a tapered inner cylindrical surface A formed so as to be fitted to the outer peripheral portion 5 of the bush 3, and 8 is a linear member such as a cord or a cable. .

When fixing the filament 8 to the casing 1, first, the filament 8 is penetrated through the inner cylindrical portion 4 of the bush 3 and the casing 1 The bush 3 is passed through the through hole 2 so that the collar portion 6 is brought into contact with the housing 1, and further, the cap 7 is fitted to the outer peripheral portion 5 of the bush 3 and is press-fitted to the cap 1.

According to the above-mentioned conventional method for fixing a linear member, the linear member is passed through the bush, and the bush is passed through the through hole of the housing. Then, the cap is fitted and press-fitted to press the bush with the cap, and the bush is pressed to fix the filament body.

However, the method of fixing the filament is structurally relatively weak because the pressure contact force of the filament is weak and cannot be reliably fixed, and the cap is used as a separate component in addition to the bush. In addition, a work for fitting the cap is required, and further, there is a problem that the fitting of the cap comes off.

Therefore, there arises a technical problem to be solved in order to easily and surely fix a linear member such as a cord or a cable penetrating into the housing to the housing.
The present invention aims to solve this problem.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail below with reference to FIG. In the figure, 11 is a housing, and a through hole 12 having a predetermined diameter is opened in the housing 11. On the other hand, in the figure, 13 is a bush, which is made of a soft material such as soft resin or soft rubber having an inner cylindrical portion 14, and the outer peripheral portion 15 of the bush 13 has a diameter smaller than that of the through hole 12. A plurality of wedge-shaped projecting portions 1 formed in a tapered shape having an outer periphery and a large diameter outer periphery and obliquely provided at the tip of the inner cylindrical portion 14 of the bush 13 toward the forward center direction.
6, 16 ... Are formed, and a flange portion 17 is provided at the rear end portion. Further, in the figure, reference numeral 18 is a linear member such as a cord or a cable.

When fixing the linear member 18 to the casing 11, first, the linear member 18 is passed through the inner cylindrical portion 14 of the bush 13 and the casing 11 The bush 13 is passed through the through hole 12, and the bush 1
3 is press-fitted, and the linear body 18 is pressed and fixed by the press-fitted bush 13.

Incidentally, first, the bush 1 is inserted into the through hole 12.
It is also possible to make the bush 13 penetrate the linear body 18 after making the bush 3 penetrate, and further press fit the bush 13. Further, when a force for pulling out the linear body 18 to the outside of the housing 11 is applied, the projecting portions 16, 16 ... Enter between the linear body 18 and the inner cylindrical portion 14 to form the linear body. By pressing the body 19 into contact with it, the resistance against the pull-out is increased, and the filament body 18 is more firmly fixed to the housing 11.

First, the inner cylindrical portion 14 of the bush 13 is
After penetrating the linear body 18 in the above direction, and slightly moving it in the pulling-out direction, the projecting portions 16, 16 ... It is also possible to press-contact 18 and then press the bush 13 through the through hole 12.

Thus, the method for fixing the filamentous body of the present invention is as follows.
As described above, the bush 13 is inserted into the through hole 12 of the housing 11.
Through and press-fit, and the bush 13 press-fitted fixes the linear body 18 by pressure, so that the linear body 1
8 is firmly fixed to the housing 11.

When a force for pulling out the linear member 18 is applied, the projecting portions 16, 16 ...
Since the filaments 18 are pressed into contact with each other and are pressed into contact with each other, the filaments 18 are more firmly fixed to the bush 13. Further, since the method of fixing the linear member uses only the bush 13 as a component, the structure is simple, and the linear member 18 such as a cord or a cable that is inserted into the housing 11 is used.
Can be easily fixed to the housing 11.

The present invention can be modified in various ways without departing from the spirit of the present invention, and it goes without saying that the present invention extends to such modifications.

[0015]

As described in detail in the above-mentioned one embodiment of the present invention, the invention according to claim 1 is, in the method for fixing a linear body, a bush through which the linear body penetrates a through hole. Since the linear body is pressed into contact with the bush by the press-fitting of the bush, the linear body can be easily and reliably fixed to the housing.

According to a second aspect of the present invention, in the method for fixing a linear member, a bush penetrating the linear member is press-fitted into the through hole, and the press-fitting of the bush presses the linear member. When the linear body is fixed to the housing and a force for pulling the linear body outward of the housing is applied, the projecting portion enters between the linear body and the inner tubular portion, and When the filament is pressed against the filament, pull-out resistance is generated in the filament.
In addition to the effects of the described invention, the filamentous body is more firmly fixed to the bush.

Further, in the invention according to claim 3, since the linear member is a cord or cable, it is possible to obtain the same effect as the effect of the invention according to claim 1 or 2 with respect to the cord or cable. Becomes Further, in the invention according to claim 4, since the soft body is a soft resin or a soft rubber, a bush made of the soft resin or the soft rubber is used.
It is possible to achieve the same effects as the effects of the invention described in 2 or 3.

Since the projecting portion is a wedge-shaped projecting portion, the wedge-shaped projecting portion has the same effect as that of the invention according to claim 1, 2, 3 or 4. It is an invention that achieves a truly remarkable effect such that the effect can be achieved.
