DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2,
Substrate 14 to be assembled to instrument panel of vehicle
A pedestal 15 for the control cable 1 protrudes at a predetermined position on the upper surface of the control cable 1. The pedestal 15 is formed in a tubular shape, and of the peripheral wall of the pedestal 15, both front and rear walls facing the control cable 1 at predetermined intervals in the longitudinal direction of the control cable 1 are first and second holding members. The walls are 16 and 17.

As shown in FIGS. 3 to 5, the control cable 1 is connected to the first and second holding walls 16, 17, respectively.
The holding holes 18 and 19 into which the outer tube 4 is inserted from the terminal side thereof are respectively provided. Further, the upper ends of the first and second holding walls 16 and 17 have respective holding holes 18 and 1.
9 are formed, respectively.
The first and second holding walls 16,
A pair of left and right retaining pieces 22 are formed at an intermediate portion of the pair 17.

The both retaining pieces 22 oppose the left and right sides of the outer peripheral surface of the outer tube 4 and are formed so as to be elastically expandable when the outer tube 4 is inserted. When the outer tube 4 is inserted to the insertion end position with respect to the holding holes 20 and 21, the outer tube 4 engages with the stepped surface 8 of the outer tube 4 to prevent the outer tube 4 from being pulled out in the direction opposite to the insertion direction. It has become. Further, each of the retaining pieces 22 is formed with a tapered guide surface 23 for inserting and guiding the outer tube 4 between the retaining pieces 22.

On the other hand, a control cable 1 for opening / closing or switching an air conditioning damper of a vehicle includes an outer tube 4 and an inner cable 2 movably inserted through the outer tube 4. A cable end 3 which is inserted into the insertion hole 12 of the operation lever 11 and is connected to the operation lever 11 is formed at one end of the inner cable 2. The other end of the inner cable 2 is provided with an air conditioning damper (not shown). Connected to the working part.

One end of the outer tube 4 is
The holding holes 20, 2 of the first and second holding walls 16, 17
1 and is extended to the vicinity of the cable end 3 of the inner cable 2, and the extended portion serves as an extension guide 5 for the inner cable 2.
A first tapered portion 6 for facilitating insertion is formed at the tip of the extension guide portion 5.

When the outer tube 4 is inserted into the outer peripheral surface of the outer tube 4 to the insertion end position of the first and second holding walls with respect to the 16 and 17 holding holes 18 and 19, the second A stopper member 10 in the form of a flange is formed which abuts against the wall surface of the holding wall 17 to limit further insertion of the outer tube 4. Further, the outer tube 4 is formed with a stepped surface 8 small-diameter portion 7 and a second tapered portion 9 sequentially adjacent to each other at positions corresponding to the pair of retaining pieces 22. In addition, as shown in FIG.
A base end thereof is rotatably mounted on a lever mounting portion of the base 14 around the support shaft 13, and a knob 11 a at a distal end of the operating lever 11 is operably protruded from a front surface of an unillustrated instrument panel. Is done.

This embodiment is configured as described above. Therefore, when attaching the outer tube 4 of the control cable 1 to the pedestal 15 of the base 14, first, the extension guide portion 5 of the outer tube 4 is retracted from the cable end 3 of the inner cable 2 by a required length. Next, as shown in FIG. 5, the cable end 3 of the inner cable 2 is inserted into the insertion hole 12 of the operation lever 11 from obliquely above. Subsequently, the inner cable 2 is pivoted downward about the insertion hole 12 as a fulcrum, and the split grooves 20, 2 at the upper ends of the first and second holding walls 16, 17 of the pedestal 15.
1 is inserted into the holding holes 18 and 19 of these holding walls 16 and 17.

Here, the extension guide portion 5 at the end of the outer tube 4 is sequentially inserted into the holding hole 19 of the second holding wall 17, between the pair of retaining pieces 22 and the holding hole 18 of the first holding wall 16. Plug in. Then, as shown in FIG. 4, at the insertion end of the outer tube 4, the stopper piece 10
Abuts against the wall surface of the holding wall 17 to stop further insertion, and the pair of retaining pieces 22 engage with the stepped surface 8 of the outer tube 4, and the engagement action causes the insertion direction of the outer tube 4. The attachment of the outer tube 4 to the pedestal 15 is completed with this. As shown in FIG. 1 and FIG.
When the outer tube 4 is attached to the inner cable 2, the extension guide portion 5 of the outer tube 4 extends to the vicinity of the cable end 3 of the inner cable 2, and guides the inner cable 2 to move.

Therefore, when the operation lever 11 is rotated about the support shaft 13 and the inner cable 2 is operated based on the operation of the lever, the inner cable 2 is moved by the extension guide portion 5 of the outer tube 4. Since the guide is guided, the problem that the inner cable 2 is buckled at the portion is eliminated.

[0018]

As described above, according to the present invention,
Buckling of the inner cable can be prevented by the extended guide portion of the outer tube, and malfunction of the inner cable can be eliminated.
