Description

[Detailed Description of the Invention] The present invention relates to a gear shift lever device installed in a small vehicle.

BACKGROUND ART In small vehicles, such as small four-wheeled automobiles with a passenger capacity of one person, the interior space is extremely small, and the installation position of a selector lever for changing gears requires consideration.

The present invention is intended to provide a shift lever device that can select the shift range of the equipped transmission in such a small vehicle without taking up much space and with a simple structure.

That is, in the present invention, a shifter guide is fixed to a bracket formed integrally with the frame, and the shifter guide is provided with a pin portion at the end passing through the body side wall, and the pin portion is connected to the selector lever provided along the body side wall. A notch mechanism is formed between the cam groove and the selector lever shaft, and a selector lever shaft is inserted through the shifter guide, and an arm is fixed to one end of the selector lever shaft, so that the arm can be slid relative to the selector lever. This is a gear shift lever device characterized by being engaged.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In Figures 1 to 5, 1 is a chassis frame, 2 is a bracket fixed to the chassis frame 1, 3 is a body side wall, 4 is a selector lever, and 5 is a connector that passes through the body side wall 3 to connect the bracket 2 and the selector lever. A shifter guide 4 is engaged with the shifter guide 4, and a selector lever shaft 6 is rotatably inserted through the shifter guide 5. Selector lever shaft 6
has an arm 7 and an arm 8 fixed at both ends, respectively. The arm 7 is a groove 9 provided in the selector lever 4.
The selector lever 4 is inserted into the selector lever 4, and is slidably held between the plates 12 without any play, and a spring 10 is interposed between the selector lever 4 and the selector lever 4, so that they are always urged against each other. Further, the arm 8 is connected to a selector cable 11 that operates a mechanism inside the transmission. The selector lever 4 has a knob 16 held by the driver at the top and a cam groove 17 at the bottom.
The fitting portions 17a,
17b and 17c are provided, respectively. 21 is a dustproof rubber boot provided between the shifter guide 5 and the body side wall 3; 22 is a shifter guide 5;
This is a nut that fixes the bracket 2 to the bracket 2. The shifter guide 5 includes a cylindrical pin portion 25 at one end,
The pin portion 25 is fitted into a cam groove 17 provided on the selector lever 4, and is provided with a flange 26 on the outer periphery and a threaded portion to be screwed into the nut 22. The shifter guide 5 is a resin molded product, and has an annular protrusion on the inner wall of the through hole so that the annular protrusion can be inserted into an annular groove 23 provided in the selector lever shaft 6 into which a small force is applied. It is made so that you cannot escape by doing so. 36 is a switch, 37 is a push plate that operates integrally with arm 8, and switch 3
Activate 6.

For installation, first the shifter guide 5 is inserted through the body side wall 3 and the bracket 2, and then fixed to the bracket 2 with a nut 22, and then the rubber boot 21 is fitted onto the body side wall 3. Separately, selector lever 4, arm 7, selector lever shaft 6, spring 1
0. Assemble the plate 12 and insert the selector lever shaft 6 into the shifter guide 5 from inside the body. With this, the selector lever shaft 6 is fixed so that it will not come off even if it is lightly pushed from the outside of the body, so the assembly can proceed without requiring two workers at the same time. Next, the arm 8 and selector cable 11 may be assembled to the selector lever shaft 6 from the outside of the body.

In FIG. 2, the position of the selector lever 4 shown in the figure, that is, the state in which the pin part 25 of the shifter guide 5 is inserted into the fitting part 17b of the cam groove 17, indicates the neutral (NEUT) position; The state where it is inserted into the insertion part 17a is the drive (DRIVE) position, and the state where it is also inserted into the insertion part 17c is the reverse (REV) position.
Show each.

Now, move the selector lever 4 to NEUT as shown in Figure 2.
When it is moved from the position to the DRIVE side, it moves with the following notch action. That is, the pin portion 25 of the shifter guide 5 passes over the protrusion 18d (see FIG. 4) between the fitting portions 17b and 17a provided in the cam groove 17 of the selector lever 4,
Therefore, the selector lever 4, which is configured to be able to slide on the arm 7, resists the bias of the spring 10,
While moving downward, insert the pin part 2 into the adjacent fitting part 17a.
Depress 5. This rotation of the selector lever 4 imparts a linear motion to the selector cable 11 through the arm 7, selector lever shaft 6, and arm 8, and operates the transmission connected to the other end of the selector cable 11.

Similarly, when returning the selector lever 4 to the NEUT side and when moving it to the REV side, the pin portion 25 of the shifter guide 5 is aligned with the cam groove 17.
moving and fitting from the fitting part 17a and 17c,
Rotate the selector lever shaft 6 in the opposite direction to the DRIVE side, and connect the selector cable 1.
1 will be activated.

As described above, according to the device of the present invention, the selector lever 4 is arranged along the side wall of the body, and the selector lever shaft 6 is held using the side wall of the body, so that the exclusive space of the gear shift lever device itself can be reduced. .

Further, the structure of the gear shift lever device of the present invention is such that an arm 7 fixed to the selector lever shaft 6 is provided in the selector lever 4 so as to be slidable and constantly biased toward the cam groove 17, and a cam with a protrusion is provided. Groove 1
7 is provided to provide a notch mechanism for rolling the pin portion 25 of the shifter guide 5 and a jumping prevention structure. Therefore, the structure and assembly can be simplified and the number of parts can be reduced, and the selector lever and other structural parts can be manufactured by resin molding, making it possible to greatly reduce the product cost. Moreover, you can get reliable functions.

Furthermore, in the device of the present invention, the shifter guide placed over the selector lever shaft can improve the rigidity and appearance of the selector lever shaft, and also provides a dustproof effect.
Since the pin portion is provided in the shifter guide and is made a part of the notch mechanism, it is possible to improve the rigidity and appearance and provide a notch function with a dustproof effect with a simple structure.
