However, in addition to the drawback that the number of parts is extremely large and the configuration is complicated, the transmission efficiency of the shift rod 4 is reduced due to the provision of the idler lever 13 and the operating force is increased. There is a serious problem.

<Purpose of the invention> The present invention was made in view of the problems of the prior art described above, and its purpose is to reduce the number of parts when the automatic transmission mount member is located below the rotating arm. To provide a control device for an automatic transmission which can easily adjust the length of a shift rod from the lower side of the floor while reducing the number of rods as much as possible.

<Means for Solving the Problems> A feature of the automatic transmission control device according to the present invention is that the control device for an automatic transmission according to the present invention constitutes a part of a control lever having a shift knob for manual operation, and that A rotating arm that rotates around a rotating shaft is provided so as to extend toward the automatic transmission mount member below the floor, and a swinging shaft is attached to the lower end of the rotating arm. An extending plate portion is pivotally supported on the swing support shaft below the floor so as to extend in the direction in which the shift lever of the automatic transmission exists or in the opposite direction thereof, and one end thereof is connected to the shift lever. A threaded portion for adjusting the length of the shift rod is formed at the other end of the shift rod that is connected to transmit the rotation of the rotation arm to the shift lever, and a threaded portion for adjusting the length of the shift rod is formed on the other end of the shift rod, which is connected to the shift rod to transmit the rotation of the rotation arm to the shift lever. A fixing part for the threaded part is formed at the end farthest from the shift rod for fixing the threaded part so that the length of the shift rod can be adjusted.

<Function> With this device, the shift lever and control lever are set to the neutral position, and the worker performs adjustment work from the bottom side of the floor to connect one end of the shift rod to the shift lever, and then The threaded part for adjusting the length of the shift rod formed at the other end of the shift rod is connected to the fixed part for the threaded part of the extension plate that is swingably supported by the free end of the rotating arm. By adjusting and fixing the length of the shift rod, the shift rod is spanned between the rotating arm and the shift lever. When adjusting the length of the shift rod from the lower part of the floor, the extension plate extends in the direction in which the shift lever extends or in the opposite direction, so the automatic transmission mount is mounted near the lower end of the rotating arm. Even if members etc. are arranged, fixing of the threaded part of the shift rod is
This means that the adjustment can be done at a location that avoids the automatic transmission mount member, making it easier to adjust the length.

When the shift knob is manually operated, the rotation of the rotating arm is transmitted to the shift lever of the automatic transmission via the extension plate and the shift rod.

<Example> In Fig. 1, 15 is a control lever;
Reference numeral 16 denotes an automatic transmission, and the automatic transmission 16 has a shift lever 17, which is rotatable around a shaft 18, and a free end of the shift lever 17 is provided with an insertion hole. 19 is formed. The control lever 15 has a shift knob 20 for manual operation and a rotating arm 21.
The rotating arm 21 is provided so as to extend toward an automatic transmission mount member 23 below the floor (not shown), and rotates around a rotating shaft 22 based on manual operation of a manual operation shift knob 20. It is something.

An automatic transmission mount member 23 is provided below the rotating arm 21, and the automatic transmission mount member 23 has a function of supporting the automatic transmission 16 via a buffer member 24. A swing support shaft 25 is provided at the lower end of the swing arm 21, and the swing support shaft 25 has an extension extending toward the rear, as shown in an enlarged view in FIG. A plate portion 26 is provided to be swingable. An insertion hole 27 is formed at the end of the extending plate portion 26, and a shaft portion 29 of a screwing fixing member 28 serving as a screwing portion fixing portion is inserted into the insertion hole 27. ,
The screwing fixing member 28 is fixed to the elongated plate portion 26 by welding or gluing so that it cannot rotate.
This fixing member 28 for screwing has a bearing plate part 30, and a shift rod 31 is attached to the bearing plate part 30.
An insertion hole 32 is formed through which the other end portion 31b is inserted. The other end 31b of the shift rod 31
is extended toward the rear of the position where the automatic transmission mount member 23 is present, and its extending direction is here the same as the extending direction of the extending plate portion 26, and the other end portion 31b is threadedly engaged. It is considered as a department. The shift rod 31 has one end 31a connected to the shift lever 1.
The shift lever 1 is inserted through the insertion hole 19 of 7.
7, the other end 31b is inserted into the insertion hole 32 of the screwing fixing member 28 and is locked to the screwing fixing member 28, and the other end 31b is
After adjusting the length of the shift rod 31, the bearing plate 30
A pair of nut members 33, 33 from both sides in the length direction
It is screwed and fixed to the fixing member 28 for screwing.

According to this, when adjusting the length of the shift rod from the lower side of the floor, the adjustment can be done at a position that avoids the automatic transmission mount member 23, making the length adjustment easier. while moving the shift rod 31 to the shift lever 1.
7 and the rotating arm 21, and since the swing radius of the extension plate part 26 and the swing radius of the shift rod 31 are different, the extension plate part 26 can be extended by its own weight to the swing support shaft 25. Free rotation downwards around the center is prevented.

FIG. 3 shows a second embodiment of the control device for an automatic transmission according to the present invention, in which a fixing portion for a screwing portion is integrally formed with an elongated plate portion 26.
With this configuration, the number of parts can be further reduced. In the embodiment, the extension plate portion 26 is configured to extend rearward from the automatic transmission mount member 23, but it may also be configured to extend in the direction in which the shift lever 17 exists. Furthermore, although the direction in which the shift rod 31 extends and the direction in which the extension plate section 26 extends are parallel to each other, the shift rod 31 may be attached obliquely to the extension plate section 26.

<Effects of the invention> The automatic transmission control device according to the invention constitutes a part of a control lever having a manual shift knob, and rotates around a pivot shaft based on manual operation of the manual shift knob. A rotating arm is provided to extend toward the automatic transmission mount member below the floor, and a swinging shaft is attached to the lower end of the swinging arm. In this case, an extension plate is pivotally supported below the floor so as to extend in the direction in which the shift lever of the automatic transmission exists or in the opposite direction, and one end is connected to the shift lever so that the rotation arm thereof can be rotated. A threaded part for adjusting the length of the shift rod is formed at the other end of the shift rod that transmits the movement to the shift lever, and a threaded part for adjusting the length of the shift rod is formed at the end of the extending plate part on the side far from the pivot shaft. Since the fixing part for the threaded part is formed to fix the threaded part so that the length can be adjusted, the following effects are achieved.

When adjusting the length of the shift rod from the lower side of the floor, the adjustment can be done while avoiding the automatic transmission mount member located below the floor, making the adjustment easier.

To make it possible to easily adjust the length of the shift rod from the lower side of the floor, the number of components of the automatic transmission control device can be reduced as much as possible.

The hole formed in the floor for connecting the rotating arm as a component of the control lever and the control lever main body can be made as small as possible, thereby reducing indoor noise caused by engine noise.

Since the shift rod and the extension plate part move approximately in the same way, the movement of the rotating arm 21 can be directly transmitted to the shift rod, and therefore, when the automatic transmission mount member is located below the shift knob, Adjustments can also be made from the bottom of the floor without changing the efficiency of the lever.
