Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shift lever device in a manual transmission for an automobile, and particularly to a swingable support structure for the shift lever.

[Prior Art] In order to change the traveling speed of an automobile transmission, a shift lever device is operated to change the gears of the transmission. Generally, a shift lever device for a manual transmission, as shown in FIG. 5, has a spherical or hemispherical change ball 2 provided on a shift lever 1, which is swingably fitted into a retainer 3 fixed to the floor of the vehicle body. The spherical protrusion 4 formed at the lower end of the shift lever 1 is inserted into the housing 8 fixed to the shift lever 6 with a pin 7 within an extension housing 5 fixed to the lower part of the retainer 3. The upper end of the shift lever 1 is grasped and rotated in the shift or select direction. The retainer 3 that supports the change ball 2 is connected to a retainer bearing 11 made of resin or the like with an elastic body 9 made of rubber or the like interposed therebetween.
The retainer bearing 11 has a spherical seat 12 along the spherical surface of the change ball 2. The spherical seat 12 is often divided into two parts, and the sixth
As shown in the figure, the change ball 2 is held between the left and right sides.

[Problems to be Solved by the Invention] However, according to the conventional shift lever device described above, the change ball 2 is fitted and fastened to the spherical seat 12 of the retainer bearing 11;
In manufacturing, it is difficult to create the change ball 2 in a shape close to a perfect sphere, and the change ball 2 and the spherical seat 12 tend to be elliptical. Therefore, while the sliding resistance of the shift lever 1 in one direction is light, the sliding resistance in the other direction is likely to be heavy, so that the operation feeling of the shift lever 1 may be unfavorable.

In view of the above circumstances, the present invention was developed with the aim of improving the shift lever device in order to improve the operating feeling of the shift lever.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention includes a retainer fixed to the floor of the vehicle body, in which a shift lever is swingably supported via a change ball. In a shift lever device for a manual transmission for a vehicle in which a change lever is engaged with a lower end thereof, the change ball has a double structure consisting of a spherical body that connects with the shift lever and a spherical shell that encloses the spherical body. At the same time, there is a diametrical phase between the spherical body and the spherical shell, and between the spherical shell and the spherical seat of the retainer bearing that fits into the spherical body, either on the front or back or on the left or right of the shift lever. This constitutes a shift lever device for a manual transmission for a vehicle, which is provided with a contact portion.

[Function] According to the above structure of the present invention, the change ball has a double structure inside and outside, and the movement of the shift lever in the shift and select directions is shared between the spherical body and the spherical shell, respectively, so the change ball is attached to the retainer bearing. By tightening the shift ball, the sliding resistance of the change ball is reduced, and the operating feeling of the shift lever is improved.

[Example] Next, an example of the present invention will be described based on the drawings.
FIG. 1 is a longitudinal sectional view of a shift lever device corresponding to FIG. 5, in which a shift lever 1 is swingably supported by a retainer 3 via a retainer bearing 11 that supports a change ball 2. As shown in FIG. The upper end of the shift lever 1 has an operation knob 13 inside the vehicle, while the lower end has a spherical projection 4 inside an extension housing 5 fixed to the lower part of the retainer 3, and the spherical projection 4 is connected to the change lever 6.
bearing 9 of housing 8 fixed to the end of
is pivotally engaged with. A rubber cover 14 covers the upper part of the retainer 3 to prevent foreign matter from entering inside.

The change ball 2 includes a spherical body 20 formed integrally with the shift lever 1 and a spherical shell 21 surrounding the spherical body 20, and is supported by a spherical seat 12 of a retainer bearing 11. As shown in FIG. 2, the spherical body 20 is a perfect spherical body, the spherical shell 21 is a substantially elliptical sphere, and the spherical seat 12 of the retainer bearing 11 is a substantially perfect spherical surface. Therefore, the spherical body 20 and the spherical shell 21 have a pair of contact portions 22 facing each other in the diametrical direction to allow movement of the shift lever 1 in the shift direction, and the spherical shell 21 and the spherical surface The seat 12 is opposed to the seat 12 in the diametrical direction for allowing movement of the shift lever 1 in the selection direction, and the contact portion 22
It has a pair of contact portions 22 located orthogonal to the contact portions 22 .

In addition, in the above embodiment, the spherical body 20 was formed integrally with the shift lever 1;
The contact portions 22 and 23 may have a separate structure in which the contact portions 22 and 23 penetrate through the spherical body 20, and the positional relationship between the contact portions 22 and 23 may be completely reversed.

Next, another embodiment shown in FIG. 3 will be explained. In this example, the position of the spherical shell 2 in the previous embodiment is made into a perfect round sphere, and the spherical shell 2 is
A pair of protrusions 24, 2 on both the inner and outer surfaces of the shift lever 1 in the diametrical direction and located at orthogonal positions to the shift direction and the select direction of the shift lever 1.
4, 25, 25 are formed. These projections 24 and 25 are connected to the spherical body 20 and the spherical seat 12.
In between, the protrusions 24, 24 contact the outer peripheral surface of the spherical body 20 in the diametrical direction so as to allow movement of the shift lever 1 in the shift direction or the select direction, respectively, while the protrusions 25, 25 contact the spherical seat. The protrusion 2 contacts the inner circumferential surface of 12 in the diametrical direction.
4 and 24, the shift lever 1 is allowed to move in the shift direction. In addition,
It goes without saying that even in this embodiment, the positional relationship of the projections 24 and 25 may be completely reversed.

Furthermore, to explain the third embodiment shown in FIG. 4, in this example, a spherical shell 21 and a spherical seat 1
A pair of protrusions 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 24, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 2, 3, 2, 2, 2, 2, 3 protrusion portions be provided, each having a pair of protrusions 24, 24,
26, and no protrusion is formed on the outer peripheral surface of the spherical shell 21. Projections 24, 2
4 allows the shift lever 1 to move in the select direction, and the protrusion 26 allows the shift lever 1 to move in the shift direction. It goes without saying that even in this embodiment, the arrangement of the protrusions 24 and 26 may be completely reversed.

The effects of each of the above-mentioned embodiments will be described. When the shift lever 1 is rocked in the shift direction
In the example shown in the figure, the spherical body 20 rotates in the front-back direction around the contact part 22 between the spherical body 20 and the spherical shell 21, and at this time, the spherical shell 21 has a contact part 23 that resists the spherical seat 12. It will not rotate due to this. In the example shown in FIGS. 3 and 4, the spherical shell 21 rotates in the front-rear direction about the protrusions 25 and 26. Then, when the shift lever 1 is swung in the select direction Y, the spherical body 20 moves to its contact portion 22 in the example shown in FIG.
However, the spherical shell 21 does not rotate due to the resistance of the spherical shell 21, but on the other hand, the spherical shell 21 rotates in the left-right direction about its contact portion 22. In the example shown in FIGS. 3 and 4, the spherical body 20 rotates in the left-right direction about the protrusion 24. As shown in FIG. As mentioned above, in the present invention,
Contact parts 22, 23 and protrusions 24, 25, 26
forms a contact portion of the spherical body 20, the spherical shell 21, and the retainer bearing 11.

[Effects of the invention] As explained above, the present invention has a change ball of a change lever that has a dual structure of inside and outside consisting of a spherical body and a spherical shell, and the spherical body and spherical shell each have a shift direction or a selection direction of the shift lever. Since we have provided a contact part that allows movement in either direction, even if the change ball is tightened by the retainer bearing in its assembly structure, the sliding resistance in the tightening direction will not be an obstacle and the shift will be possible. Since the lever can be smoothly rocked in the shift direction and the selection direction, the operating feeling of the shift lever is improved.
