a is inserted into the cable holder 41 through the locking piece insertion slit 74.

Due to the spring force of the coil spring 47, the sliding throttle valve 6 is biased in the direction of closing the bench lily part 10, and by pulling the inner wire 45 against the spring force of the coil spring 47, the sliding throttle valve 6 is forced to slide. The throttle valve 6 can be opened.

At the bottom of the sliding throttle valve 6, a cutaway 48 is provided facing upstream along the intake direction 8, and a recess 49 is provided that is recessed upward. Further, the jet block 14 is integrally provided with a screen 50 which can be thrust into the recess 49 upstream of the jet needle 38 when the sliding throttle valve 6 is closed.

Next, the operation of this embodiment will be explained. When the cable holder 41 is attached to the sliding throttle valve 6, the locking piece 45a at the end of the inner wire 45 is inserted through the locking piece insertion slit 74 into the first holder half 57.
Then, the first holder half 57 and the second holder half 83 are inserted into the cylindrical part 52. At this time, the locking flanges 59 and 60 of the first holder half 57
The cable holder 41 is attached to the cylindrical portion 52 in such a position that it is located between the engaging protrusions 55 and 56 of the cylindrical portion 52.
Push it inside. Next, with the inner wire 45 pulled out from the wire insertion slit 73 between the inner surface of the cylindrical portion 52 and the outer surface of the cable holder 41,
Engage a box wrench with the operating portion 58 or engage a screwdriver with the groove 84 of the operating portion 58, and press the coil spring 42 to contract while pressing the first coil spring 42.
An angular displacement operation is performed on the holder half body 57. When the first holder half 57 is angularly displaced by approximately 90 degrees, the first regulating protrusion 6
1 and 62 come into contact with the engaging protrusions 55 and 56, and further angular displacement of the first holder half 57 is prevented.
Therefore, when the pressed state of the first holder half 57 is released, the first holder half 57 is displaced in a direction away from the bottom surface 51 of the cylindrical portion 52 due to the spring force of the coil spring 42, and the engagement recesses 63, 64 Engagement protrusion 5
5 and 56 are engaged, thereby completing the attachment of the cable holder 41 to the sliding throttle valve 6.

At this time, the locking collar 40 at the upper end of the jet needle 38 is held in the engagement recess 39 by the second holder half 83.
The jet needle 38 is held against the sliding throttle valve 6.

Next, the coil spring 47, into which the inner wire 45 has been inserted in advance, is fitted into the first holder half 57, and the locking portion 47a is inserted into the locking piece insertion slit 74. This prevents the locking piece 45a from falling off from the locking piece insertion slit 74. Furthermore, the inner wire 45 is inserted into the insertion hole 67 and pulled up to come into contact with the locking step 68, and the cover 30 is attached to the upper end of the throttle valve guide cylinder 7.

In this way, the work of attaching the cable holder 41 to the sliding throttle valve 6 is completed, but when removing it, the first holder half 57 of the cable holder 41 is pressed and angularly displaced in the opposite direction to that described above. Often, this removal work is also easily completed.

In the above embodiment, the length _l2 of the wire insertion slit 73 is made relatively short, and the locking portion 47 is attached to the coil spring 47 in order to prevent the locking piece 45a from coming off.
a, and the locking portion 47a is inserted into the locking piece insertion slit 74 to prevent the locking piece 45a from falling off. However, the cable holder 4 shown in FIG.
1', where l ₂ can be made long, there is no need to provide the locking portion 47a.

7 to 9 show a cable holder according to another embodiment of the present invention, and this cable holder 85 includes a first holder half 86 and a second holder half 86.
7 are mutually screwed together. First holder half 8
6 is formed into a cylindrical shape with a female thread 88, and a locking collar 5 having first regulating protrusions 61', 62' and second regulating protrusions 65', 66' at one end thereof.
9' and 60' are extended on both sides along one diameter line.
On the other hand, the second holder half 87 is basically formed into a cylindrical shape with a male screw 89 on its outer circumferential surface that is screwed into the female screw 88, and the locking piece 45a of the inner wire 45 is engaged inside the second holder half 87. An engagement hole 69' serving as an engagement portion is bored at one end of the engagement hole 69', which is connected to the engagement hole 68' via a locking step 68'.
7' is drilled. Further, a wire insertion slit 73' and a locking piece insertion slit 74' are provided on the side of the second holder half 87 in series with each other. Furthermore, a cross-shaped groove 84' for engaging a driver is provided at one end of the second holder half 87.

This cable holder 85 is a second holder half 8
7 is inserted into the cylindrical part 52 in a state in which the amount of protrusion from the first holder half body 86 is reduced, and in a posture in which the locking collar parts 59' and 60' are positioned between the engaging protrusions 55 and 56. Ru. Next, when a driver is engaged with the groove 84' and angularly displaced by 90 degrees, the first regulating protrusions 61', 6
2' comes into contact with the engaging protrusions 55, 56 and is prevented from angular displacement. Then, when the second holder half 87 is further manipulated to angularly displace, since the first holder half 86 is prevented from angularly displacing, the second holder half 87
It protrudes from the lower surface of the holder half 86 and comes into contact with the bottom surface 51 of the cylindrical portion 52, causing the locking flanges 59', 60' of the first holder half 86 to engage with the engaging protrusions 55, 56.

In this way, the cable holder 85 is attached to the sliding throttle valve 6 so as to be sandwiched between the engaging protrusions 55 and 56 and the bottom surface 51 of the cylindrical portion 52.
When removing it, the angular displacement operation may be performed in the opposite direction to that described above. In this embodiment, the male thread 89 and the female thread 88 cooperate with each other to constitute the biasing means of the present invention.

Furthermore, if the cable holder 85 is constructed by screwing the two holder halves 86 and 87 together, there is a risk that the cable holder 85 may come loose due to vibrations, etc. A protrusion 90 that can be brought into pressure contact with the inner surface of the half body 86 is provided in a protruding manner, and the frictional force acting between the protrusion 90 and the inner surface of the first holder half body 86 prevents the two holder halves 86 and 87 from being screwed together. The cable holder 85 is firmly maintained, so that the cable holder 85 will not come off the sliding throttle valve 6 due to vibration or the like loosening the threaded state.

C. Effects of the invention As described above, according to the invention, when assembling the cable holder, the first holder half is inserted into the cylindrical part and the angular displacement operation is performed within the cylindrical part. By simply bringing each locking flange face to face with the lower surface of the corresponding engagement protrusion of the sliding throttle valve, and then separating both holder halves from each other using the biasing means, each locking flange can be moved between its pair. Since the regulating protrusions can sandwich both sides of each engaging protrusion and make pressure contact with the lower surface of the engaging protrusion, the cable can be easily attached to the sliding throttle valve itself, which requires high machining accuracy, without the need for special thread machining. The holder can be accurately attached to the sliding throttle valve, thus contributing to cost reduction of the sliding throttle valve.

In particular, when performing an angular displacement operation within the cylindrical portion of the first holder half, the height from the lower surface of the locking collar is greater than the distance between the engaging protrusion and the bottom surface of the cylindrical portion. The angular displacement operation of the first holder half can always be stopped at a predetermined proper position by the engagement between one of the regulating protrusions and the engagement protrusion. When both holder halves are separated from each other, both sides of the corresponding engagement protrusion can be easily and securely held between the pair of regulating protrusions on each locking flange, improving the efficiency of assembly work. It can contribute greatly.
