[Detailed Description of the Invention] (Field of Industrial Application) The present invention mainly relates to a floor shift type shift lever support device for a gear transmission for a vehicle.

(Prior Art) Generally, as a floor shift type shift lever support device, as shown in Japanese Utility Model Application Publication No. 59-180922, a spherical shape of the shift lever is formed by a sheet divided into two in the vertical direction. There is a configuration in which the parts are supported on a spherical surface so that shift and select operations can be performed. In FIG. 6, which shows a shift lever support device of a different type, the spherical portion 11 of the shift lever 10 is mounted on a rubber cushion (not shown) within a cap 34 fixed to the upper surface of a shift lever support plate 33. It is supported for shift and direct operation via etc. In addition, in FIG. 6, the select bell crank 36 that is linked to the select operation of the shift lever 10 is rotatably supported by a bell crank shaft 35 that is also fixed to the upper surface of the support plate 33 with bolts or the like. and a shift stopper 3 for regulating the amount of shift operation of the shift lever 10.
8 is also fixed to a part of the support plate 33 by welding or the like.

(Problems to be Solved by the Invention) In the shift lever support device shown in FIG.
4 and a bell crank shaft 35 that rotatably supports the select bell crank 36 are individually attached to the support plate 33, so that the shift lever 10 and the select bell crank 36 are in an interlocking relationship with each other. There is likely to be variation in the mounting dimensional accuracy between the two. Also, these caps 3
4. Since the select bell crank 35, the above-mentioned shift stopper 38, etc. are each separate parts, the number of parts for the shift lever support device increases, and there are also problems in assemblability and productivity.

(Means for Solving the Problems) The present invention, as shown in FIGS. 1 and 2, divides the spherical portion 11 of the shift lever 10 into equal parts on a plane parallel to the axis of the shift lever 10. It is spherically supported by the seats 5, 5 to enable shift and select operations, and these two divided seats 5,
5 are mutually connected by a plurality of bolts 15. The spherical support parts 6, 6 of these two divided seats 5, 5 are made thinner than other parts of the shift lever 1.
It has a holding elasticity for the spherical part 11 of 0. These divided sheets 5, 5 constitute a shift stopper 8 that restricts the shift operation of the shift lever 10. Further, some of the bolts 15 mentioned above that connect the two divided sheets 5, 5 are arranged on the back of the shift stopper 8, and one of these bolts 15 is used to select the select bell. A crank 20 is rotatably supported.

(Function) According to the above configuration, each of the divided sheets 5, 5 can independently position and support the spherical part 11 of the shift lever 10, thereby always keeping the operating fulcrum of the shift lever 10 constant. It becomes possible to determine accurately. Further, the shift stopper 8 is constituted by the two divided sheets 5, 5 that support the shift lever 10, and one of the bolts 15 that connects these two divided sheets 5, 5 to each other. By supporting the select bell crank 20 using the above method, it is possible to reduce the number of parts of the shift lever support device, and also improve the mounting dimensional accuracy of the shift lever 10 and the select bell crank 20, which are in an interlocking relationship with each other. can be increased. In addition, by arranging the bolt 15 that connects the two divided sheets 5, 5 on the back of the shift stopper 8, this shift stopper 8
The rigidity of the material is increased.

The above-mentioned two divided seats 5, 5 are connected to the shift lever 10.
Since the divided sheets 5, 5 are equally divided in a plane parallel to the axis of the sheet, the divided sheets 5, 5 have the same shape, reducing the cost of molds for molding them, and improving their ease of assembly. Moreover, a shift lever 10 is provided on the spherical support portions 6, 6 of each divided seat 5, 5.
Since it has elasticity to hold the spherical part 11 of the shift lever 10, it absorbs dimensional changes due to wear, thermal expansion, etc. of the spherical support parts 6, and maintains a stable supporting force for the spherical part 11 of the shift lever 10. I can do it.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 5.

First, Fig. 1 shows a floor shift type shift lever support device in longitudinal section, Fig. 2 shows a part of Fig. 1 in plan section, and Fig. 2 shows an exploded perspective view of the appearance of the shift lever support device. In FIG. 3, a pair of left and right holding plates 2 and 3 are integrally erected on the upper surface of the base plate 1 by means such as spot welding. Between these holding plates 2 and 3, divided sheets 5 and 5 are equally divided left and right by a plane perpendicular to the upper surface of the base plate 1 (a plane parallel to the axis of the shift lever 10, which will be described later). is assembled. In other words, as is clear from FIG. 4, which shows an exploded perspective view of these two divided sheets 5, 5, and FIG. 5, which shows a cross section of the joint of the divided sheets 5, 5, there are Bolt insertion holes 7, 7 are formed. Then, by inserting the bolts 15 into these bolt insertion holes 7, 7 from the outside of one holding plate 2, and tightening the nuts 16 against these bolts 15 from the outside of the other holding plate 3,
The two divided sheets 5, 5 are sandwiched between the holding plates 2, 3 and connected to each other. In addition, a collar 17 is installed in each bolt insertion hole 7, 7 of both divided sheets 5, 5, and is located coaxially with each bolt 15 and interposed between left and right holding plates 2, 3. These collars 17 allow both divided sheets 5, 5 to be attached to bolts 15.
and nut 16 prevent excessive tightening. In addition, each of these bolt insertion holes 7,
At the outer end of 7, an elastic body 18 is interposed between each holding plate 2, 3 and the divided sheets 5, 5, and this elastic body 18 allows each bolt 15 and a nut 16 to be tightened thereto to be tightened. This will prevent loosening.

The two divided sheets 5, 5 are made of a material such as synthetic resin or aluminum, and include spherical support portions 6, 6 that support the spherical portion 11 of the shift lever 10 so as to wrap around it from both sides.
are formed respectively. That is, the spherical portion 11 of the shift lever 10 is supported by the spherical support portions 6, 6 of the two divided seats 5, 5 to enable shift and select operations. The lever tip (lower end) of this shift lever 10 is the first
As shown in the figure, it is connected by a predetermined connecting member 13 to a shifting cable (not shown) using a push-pull cable. Further, the spherical portion 11 of the shift lever 10 is integrally formed with a select arm 12 extending laterally from one side of the spherical portion 11, and this select arm 12 extends from the opening 9 of one of the divided seats 5. protruding to the outside.

Now, as is clear from FIGS. 1 and 2, the spherical support parts 6, 6 of the two divided sheets 5, 5 are formed thinner than other parts. Therefore, if the diameter of the hemispherical portion formed by these spherical support parts 6, 6 is set to be slightly smaller than the diameter of the spherical part 11 of the shift lever 10, the spherical support parts 6, 6 exerts a holding elasticity against the spherical portion 11 of the shift lever 10. Note that a shift stopper is provided at a position below the spherical support portions 6, 6 in both the divided sheets 5, 5 by connecting both the divided sheets 5, 5 to each other, as shown in FIGS. 1 and 4. 8 are made up. This shift stopper 8 is a part of the shift lever 10 shown in FIG.
4 and regulates the amount of shift operation.

Among the bolts 15 that connect the two divided sheets 5, 5 to each other, the pair of bolts 15 that connect the lower parts of the divided sheets 5, 5 are attached to the back of the shift stopper 8. The shift stopper 8 functions as a reinforcing member. Similarly each of these bolts 15
One of them also serves as a bell crank shaft 15a that rotatably supports the select bell crank 20 (see FIGS. 2 and 3). Therefore,
This bell crank shaft 15A is positioned directly with respect to each of the divided sheets 5, 5 supporting the spherical portion 11 of the shift lever 10, and the shift lever 10 and the shift lever 10 are interlocked with each other as described below. The mounting dimensional accuracy with the select bell crank 20 is improved. The tip of the select arm 12 of the shift lever 10 is spherically connected to one end 20a of the select bell crank 20 as shown in FIG. 2, and the other end 20b is connected to a selecting cable (not shown) using a push-pull cable. It is provided with a pin 21 coupled to.

In the shift lever support device configured as described above, the shift lever 10 is moved along the arrow A-A in FIG.
When a shift operation is performed in this direction, the movement of the tip (lower end) of the shift lever 10 at this time is transmitted to the transmission side through a shifting cable (not shown). Further, when the shift lever 10 is selected in the direction of arrow B-B in FIG.
The select bell crank 16 is rotated around A, and the movement of the select bell crank 16 is transmitted to the transmission side through a selecting cable (not shown) connected thereto.

As described above, the shift operation of the shift lever 10 is regulated by the part 14 of the shift lever 10 coming into contact with the shift stopper 8 constituted by the two divided sheets 5, 5. Ru. Further, the selection operation of the shift lever 10 is regulated by the protrusion 20c of the select bell crank 20 that is interlocked with this, coming into contact with the select stopper 22 formed on one of the holding plates 2 (see Fig. 3). reference).

Now, the above-mentioned two divided seats 5, 5 can each independently position the spherical part 11 of the shift lever 10 by the respective spherical support parts 6, 6, so that the shift and select operation of the shift lever 10 can be performed independently. It becomes possible to always properly determine the operating fulcrum (the center point of the spherical part 11) at the time. Further, these two divided sheets 5, 5 may have the same shape mutually, which reduces the cost of molds for molding these divided sheets 5, 5, and also allows both divided sheets 5, 5 to have the same shape. Because they are compatible, assembly work can be done efficiently.

Further, the spherical support portion 6 of both divided sheets 5, 5,
6 has elasticity to hold the spherical portion 11 of the shift lever 10 as described above, so that dimensional changes due to wear, thermal expansion, etc. of the spherical support portions 6, 6 can be absorbed by the elasticity. , it becomes possible to always stabilize the support function of the shift lever 10.

(Effects of the Invention) As described above, the present invention has a structure in which the spherical support part of both divided sheets, which are equally divided in a plane parallel to the axis of the shift lever, is formed to have a thinner wall than the other parts, so that the spherical support part of the shift lever has a retaining elasticity against the spherical part of the shift lever. This allows each divided sheet to independently position and support the spherical part of the shift lever, which allows the operating fulcrum of the shift lever to be determined accurately at all times. Of course, each of these divided sheets has the same shape, which reduces the mold cost for molding them, improves the ease of assembly, and prevents wear and thermal expansion of the spherical support. Dimensional changes can be absorbed by elasticity, and the supporting force for the spherical portion of the shift lever can be maintained in a stable state.

In addition, the present invention configures a shift stopper with both split sheets supporting the shift lever,
Moreover, by supporting the select bell crank using one of the bolts that connect these two divided sheets to each other, the number of parts of the shift lever support device can be reduced, and the parts can be linked together. By increasing the dimensional accuracy of the installation of a certain shift lever and select bell crank, and by placing some of the bolts that connect the two split seats on the back of the shift stopper, this The rigidity of the shift stopper can be increased.
