BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-vibration support device for a control cable for transmitting a shift operation of a shift lever to an automatic transmission.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a control cable 200 for connecting a connecting rod (not shown) connected to an outer lever of an automatic transmission and an eye rod (not shown) of a shift lever, and an inner periphery thereof. The control cable 2 has a distal end taper portion 310 abutting on the taper portion 410.
00 and the inner peripheral taper portion 4
10 and a flange portion 420, a metal hub 400 whose rear portion is swaged and fixed to the outer casing 100 (the inner cable 1 is inserted) and a resin sleeve 300 are fitted therein, and a tip portion is internally fitted to the metal hub 400. A metal hub 400 and a metal pipe sleeve 5 from the rear side of the flange 420 to the vicinity of the center of the metal pipe sleeve 500 via the flange 420.
A cushion rubber 610 and a seal rubber 620 which cover the outer periphery of the rubber seal 00, a ring 700 for caulking the seal rubber 620 near the center thereof, and a cap 800 which is bent and caulked on the outer periphery of the cushion rubber 610 and the seal rubber 620 via a washer 810. And the cap 800
There is known an anti-vibration support device B for a control cable, which is fixed to an automatic transmission housing (both not shown) via a retainer and a clip.

[0003]

However, in the conventional anti-vibration support device B for the control cable, the vibration of the automatic transmission is transmitted to the shift lever, and the control cable 200
Abnormal noise (chattering) occurs between the eye rod and the resin sleeve 300, which are connected to each other. An object of the present invention is to provide an anti-vibration support device for a control cable which prevents generation of abnormal noise.

[0004]

In order to solve the above-mentioned problems,
The present invention provides a control cable for connecting an automatic transmission side member and a transmission lever side member, which has a bent end portion that deflects outward, a resin sleeve for loosely fitting an inner cable, an inner peripheral locking step, and A cylindrical metal hub having an outwardly projecting portion, a rear side of which is fixedly fastened to the outer casing; and a metal pipe sleeve in which the resin sleeve is fitted, and a tip portion of which is internally fitted to a front portion of the metal hub. And a vibration absorbing member provided with an annular rubber interposed over the inner surface of the annular body, disposed between the inner peripheral locking step and the bent end portion, and a rear side of the outwardly projecting portion. A rubber member that covers the outer periphery of the metal hub and the metal pipe sleeve through the outwardly protruding portion to the vicinity of the center of the metal pipe sleeve; and a ring that caulks the rubber member around the center of the metal member. Outside the rubber member And a cap assembled to, and employs a configuration formed by fixing the cap to the body side member.

[0005]

[Function and effect of the invention] Vibration of the automatic transmission transmitted through the control cable is absorbed by sliding contact with the inner peripheral surface of the annular rubber interposed over the inner surface of the vibration absorbing member. Since the bent portion at the tip of the sleeve is in contact with the side surface of the annular rubber of the vibration absorbing member, the whirling of the eye rod is reduced, and the mutual vibration generated between the resin sleeve and the tip of the eye rod is reduced. Therefore, it is possible to prevent abnormal noise (chattering noise) generated between the shift lever and the automatic transmission from reaching the vehicle interior.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. The control cable anti-vibration support device A shown in the figure includes an inner cable 1, a resin sleeve 2, a metal hub 3, a metal pipe sleeve 4, and a vibration absorbing member 5.
, A rubber member 6, a ring 7, and a cap 8,
A retainer and a clip are mounted on the concave portion 822 of the cap 8, and the retainer is mounted on an automatic transmission housing (neither is shown).

[0007] The inner cable 1 is formed by bundling a plurality of carbon steel oil-tempered wires for a spring, and has one end 11 connected to a connecting rod (not shown) connected to an outer lever of the automatic transmission. The other end 12 is connected to a tip 901 of an eye rod 900 of a shift lever. When a shift operation of a shift lever (not shown) is performed, the inner cable 1 slides left and right in the drawing, whereby the automatic transmission shifts to the first speed,
Second speed, drive position, etc. are set.

The resin sleeve 2 is made of PEED (polyester elastomer), has a bent front end portion 21 deflecting outward, and a rear end turn 22, and the inner cable 1 is loosely fitted therein.

The metal hub 3 formed by aluminum die casting and having a substantially cylindrical shape includes an inner peripheral locking step 31 and a flange section 3.
2 and a curved portion 30, and an extended rear portion 33 is fixed to the outer casing 100 by caulking.

[0010] The metal pipe sleeve 4 is
And the front end surface of the metal hub 3 is slidably fitted to the front portion 34 of the metal hub 3 with the front end surface abutting on the front end bent portion 21 and the bent end portion 41 bent outward at the bent portion 30 position. ing. still,
35 is a resin cover.

As shown in FIG. 3, the vibration absorbing member 5
An annular rubber body 52 is provided on an inner surface of an annular body 51 made of iron. The annular rubber body 52 is disposed between the inner peripheral locking step 31 and the bent end portion 21.

The rubber member 6 has an escape portion 611 covering the outer periphery of the metal hub 3 from the front portion to the rear portion of the flange portion 32.
With cushion rubber 61 and rear with cushion rubber 6
The metal hub 3 and the seal rubber 62 covering the outer periphery of the metal pipe sleeve 4 from the front of the flange portion 32 to the vicinity of the center of the metal pipe sleeve 4 in contact with the front part of the metal pipe sleeve 4.

The ring 7 is a member for caulking the front portion of the seal rubber 62 near the center of the metal pipe sleeve 4.

The cap 8 is made of metal and has a washer 81 provided at the rear of the cushion rubber 61 and a caulking portion 8.
21 and a cap body 82 that covers the outer periphery of the washer 81, the cushion rubber 61, and the seal rubber 62.

The anti-vibration support device A for a control cable according to this embodiment has the following advantages. (A) Vibration of the automatic transmission transmitted through the inner cable 1 is absorbed by sliding on the inner peripheral surface of the annular rubber 52 interposed over the inner surface of the vibration absorbing member 5 and the resin sleeve 2 is a vibration absorbing member 5
Abut on the side surface of the annular rubber 52, the whirling of the eye rod 900 is reduced, and the mutual vibration generated between the resin sleeve 2 and the eye rod tip 901 is reduced. Therefore, it is possible to prevent abnormal noise (chattering noise) generated between the shift lever and the automatic transmission from reaching the interior of the vehicle. (A) The inner peripheral locking step 31 is formed on the metal hub 400, the distal bent portion 21 is formed on the resin sleeve 300, and the vibration absorbing member 5 is placed between the inner peripheral locking step 31 and the distal bent portion 21. A simple change or addition of the arrangement is made to the anti-vibration support device B for the control cable, so that the anti-vibration support device A for the inner cable is used. Also,
The durability is almost the same as that of the conventional anti-vibration support device B.
