The device described in Japanese Utility Model Application Publication No. 59-102527 (hereinafter referred to as the conventional example) is constructed as shown in FIG. In this device, the first shaft 61 is supported at one end, and the second shaft 63 is supported at both ends.

[Problems to be solved by the invention] In the conventional device, the first shaft 61 and the second shaft 63
Since the distance between the axes of the outer pipes 62 and 64 is equal to the outer diameter of the outer pipes 62 and 64, there is a problem that the height of the apparatus becomes high.

Although the conventional device does not have the above-mentioned problems of the conventional device, it has problems such as difficulty in retaining grease in the bearing 68 and difficulty in controlling the dimensions between both ends of the bracket 69, making it difficult to achieve mounting accuracy.

In the conventional device, since the first shaft 61 is supported on a cantilever, there is a problem that the rigidity is low and the backlash is large.

In view of the above circumstances, it is an object of the present invention to provide a highly rigid device that has a small height dimension and is easy to install with precision.

[Means for Solving the Problems] The speed change operating device of the present invention includes an operating lever having a yoke at one end thereof, a first shaft for pivotally supporting the operating lever so as to be tiltable in two intersecting directions, and a first
a second shaft that intersects in close proximity to the shaft, two outer pipes into which the two shafts are rotatably inserted, both ends of the first shaft and the second shaft, and outer pipes corresponding to the both ends. The two outer pipes are recessed in the center so that the distance between their mutual axes is smaller than the inner diameter of the pipes, and the two outer pipes are fixed in a crossed manner. The center portion of at least one of the first shaft and the second shaft has a small diameter and is inserted into the shaft, and both ends of the first shaft are each fixedly supported by the yoke. , wherein both ends of the second shaft are each fixedly supported by a support member.

[Function] In the present invention, the two outer pipes 3 and 4 are fixed together in a recessed state,
Further, since at least one of the first axis 1 and the second axis 2, which intersect close to each other, has a small diameter in the center, that is, in the vicinity of the intersection, the height dimension becomes small. Furthermore, since both the first shaft 1 and the second shaft 2 are supported by the outer pipes 3 and 4, it is possible to use a single shaft with a structure in which both ends are supported, thereby increasing the rigidity. Furthermore, since the dimensions of the shaft can be easily controlled, mounting accuracy is also guaranteed.

In addition, the first shaft 1 and the second shaft 2 are connected to the outer pipes 3 and 4.
Since the structure holds lubricating oil easily, the problem of insufficient lubrication does not occur.

The tilting operation in the Y direction is performed using the second axis 2 as a rotation axis.

The yoke 6 is provided with an arm 11, to which a shift operation cable 13 is connected via a joint 12. Further, the second outer pipe 4 is provided with an arm 14, to which a select operation cable 16 is connected via a joint 15.
are connected. 17 is a base, and the bracket 9 is fixed on this base 17. With this configuration, when the operating lever 5 is tilted in the Y-Y direction, a select operation is performed, and when it is tilted in the X-X direction, a shift operation is performed. A coiled spring 18 is wound around the second outer pipe 4, one end of which is engaged with a locking hole 19 of the bracket 9, and the other end of which is brought into contact with the upper surface of the first outer pipe 3. Therefore, when the operating lever 5 is not operated, the operating lever 5 is tilted to the left in FIG.

The first outer pipe 3 and the second outer pipe 4 into which the first shaft 1 and the second shaft 2 are inserted will be explained in detail based on FIGS. 5 and 6. The first outer pipe 3 and the second outer pipe 4 are welded to each other at their central portions and are fixed in a perpendicular state. At the fixed part, the pipes are recessed by a dimension slightly larger than the radius of the outer diameter of each pipe, and both pipes 3 and 4 are formed so that there are no protrusions inside. Therefore, the first shaft 1 can be inserted into the first outer pipe 3 and the second shaft 2 can be inserted into the second outer pipe 4 in a penetrating state.

FIG. 7 shows the first outer pipe 3 and the first shaft 1.
It is shown. The first shaft 1 has a central portion 1a formed to have a smaller diameter than both end portions 1b, and a head portion 1 at one end.
C, a male threaded portion 1d is formed at the other end. Two bushes 21 are inserted between the first shaft 1 and the first outer pipe 3. This bush 21 is a bush with a flange, and the length of the body is the first shaft 1.
It is slightly shorter than one end 1b of . 1st
When the bushes 21 are inserted into each of the opposite ends 1b of the shaft 1, a space 22 surrounded by the end faces of the bushes 21 and the inner peripheral surface of the first outer pipe 3 is defined around the central part 1a. This space 22 is used as an oil reservoir 22 for sealing in grease or the like. The first shaft 1 is connected to the two side walls 6a and 6b of the yoke 6.
It is fixed to the yoke 6 by inserting it into the holes 6c and 6d formed in the yoke 6 and screwing the nut 23 into the male threaded portion 1d. 24 is a washer inserted into the male threaded portion 1d.

FIG. 8 shows the second outer pipe 4 and the second shaft 2.
It is shown. The second shaft 2 also basically has the same configuration as the first shaft 1, except for the axial dimension.
The center portion 2a is formed to have a smaller diameter than both end portions 2b. Both shafts 1 and 2 intersect close to each other at their respective narrow diameter portions. Note that female screw portions 2c and 2d are formed at the two ends 2b, respectively. The second shaft 2 and the second outer pipe 4
Two bushings 25 are inserted between. This bush 25 is a bush with a flange, and the length of the body is slightly shorter than one end 2b of the second shaft 2. When the bushings 25 are inserted into both ends 2b of the second shaft 2, a space 26 is formed around the central part 2a, surrounded by the end faces of the bushings 25 and the inner peripheral surface of the second outer pipe 4. This space 26 is an oil reservoir 26 in which grease or the like is sealed.
used as.

The second shaft 2 is inserted into the second outer pipe 4 after the first shaft 1 is inserted into the first outer pipe 3. In this case, if the bush 25 is inserted into the second outer pipe 4, the second shaft 2 and the first shaft 1 will interfere, so the bush 25 is not inserted and only the second shaft 2 is inserted into the second outer pipe 4. Insert inside. By doing so, the first shaft 1 and the second shaft 2 can be separated by the thickness of the bush 25, so that the second shaft 2 can be passed through the space above the central portion 1a of the first shaft 1. After passing the second shaft 2 through the second outer pipe 4 in this manner, the two bushes 25 are inserted from each of the four ends of the second outer pipe 4. On the other hand, side plates 9a and 9b of the bracket 9 are formed with bolts 9c and 9d for passing bolts 7 and 8, respectively. Therefore, if the second shaft 2 and the second outer pipe 4 are inserted between the side plates 9a and 9b, and the bolts 7 and 8 are screwed into the female threaded portions 2c and 2d at both ends of the second shaft 2 through the holes 9c and 9d. , the second shaft 2 is fixed to the bracket 9.

In the embodiment described above, both the first shaft 1 and the second shaft 2 are formed to have a small diameter in the center, but the center part of either the first shaft 1 or the second shaft 2 is made to have a small diameter, The other shaft may have the same diameter as the central portion including both ends. That old lady's bush 2
The first outer pipe 3 is made thicker by increasing the wall thickness of parts 1 and 25.
It is preferable that the first shaft 1 and the second shaft 2 are held in the second outer pipe 4 in a slidable manner.

Further, in the above embodiment, the first outer pipe 3 and the second outer pipe 4 are fixed at right angles, but they may be fixed at an angle other than a right angle. In this case, the operating lever can be tilted in a cross direction other than the right angle direction.

Next, the advantages of each embodiment of the present invention will be explained.

The first outer pipe 3 and the second outer pipe 4 are intersected at the intersection, and the first shaft 1
and the second shaft 2 intersect closely at the position of one of the narrow diameter parts, so the distance between the axes of both pipes 3 and 4 is shortened, and the height dimension of the transmission operating device is reduced. be able to.

Both the first shaft 1 and the second shaft 2 can be constructed as a single piece, each supported by outer pipes 3 and 4, and both ends supported by a yoke 6 and a bracket 9, so that rigidity is improved. It is high and does not wobble even after long-term use.

The distance between the two side plates 9a and 9b of the bracket 9 is determined by the distance between the second shaft 2 inserted between the side plates 9a and 9b.
However, since the length dimension of the shaft can be easily achieved with high accuracy in machining, the distance between the side plates 9a and 9b can be easily ensured with high accuracy.

The first shaft 1 and the second shaft 2 are lubricated by an oil reservoir 2.
This is done using grease or oil sealed in bushes 2 and 26, but since this grease and oil is prevented from leaking by bushes 21 and 25, the lubricating oil is reliably retained and no lack of lubrication occurs. .

As mentioned above, the second shaft 2 can be mounted to the bracket 9 with high accuracy, so there is no need to use a joint that can absorb dimensional errors to fix the second shaft 2, and the two bolts 7 and 8 It is sufficient to fix it with Therefore, manufacturing costs are reduced and the structure becomes stronger.

Although the embodiments of the present invention have been described above, various modifications can be made to the present invention without departing from the gist thereof.

[Effects of the invention] The device of the present invention has a small height dimension, easy to achieve mounting accuracy, and is a highly rigid device.
