Description

[Detailed Description of the Invention] This invention relates to an improvement of a boot device for a change lever for an automobile.

Conventionally, the above-mentioned boot structure supports the ball joint portion 2 of the change lever 1, such as the structure shown in FIGS. 1a and 1b disclosed in Japanese Utility Model Publication No. 53-7460. The inner metal fitting 3 and the outer metal fitting 4 are airtightly connected by an annular mount rubber 5 in a horizontal plane passing approximately through the center of the ball joint portion 2. There is one consisting of thick (hard) portions 6, 6 that strongly resist movement in the shift direction, and thin (soft) portions 7, 7 that weakly resist rocking in the shift direction.

However, the flexible portion 5 has a thick wall, a thin wall portion 6,
7 at the same time, the molding die becomes complicated, and the number of pieces that can be molded simultaneously in one molding process is extremely limited, causing an increase in costs.

Furthermore, as shown in Fig. 2, Japanese Utility Model Application Publication No. 56-14735 proposes a device in which a separate dust seal boot 8 is provided between the upper edge of the inner fitting 3 and the edge of the outer fitting 4. However, in this case, the upper end edges of both metal fittings are bent and the above-mentioned boot is secured to the bent portions, and it is necessary to bend both metal fittings in order to attach the boot. Additionally, the inner metal fitting to which the ball seat that supports the ball joint of the change lever is attached cannot be used for attaching the boots, as its upper edge is bent inward to hold the ball seat. .

This idea was made in view of the above-mentioned conventional problems, and the above-mentioned boot, which seals the interior and exterior of the vehicle interior, is attached using a mount rubber that connects the inner and outer metal fittings. Processing such as bending both metal fittings is kept to a minimum.

Therefore, this invention consists of a change lever inserted into an insertion hole in the floor panel of the vehicle interior and connected to a transmission control rod outside the vehicle interior, and a cylindrical outer part attached to the edge of the insertion hole in the floor panel. A metal fitting, a cylindrical inner metal fitting that supports a ball seat located within the outer metal fitting and supporting a ball joint portion of the change lever, and an inner surface of the outer metal fitting and an outer surface of the inner metal fitting are connected, A mount rubber having a hollow portion that is hard in the select direction of the lever and soft in the shift direction, an engaging protrusion extending upwardly at least on the inner metal fitting side of the mount rubber and formed at the upper end of the metal fitting, and the engaging protrusion. The present invention relates to a boot device for a change lever for an automobile, characterized in that it comprises a mount rubber boot that is engaged with the outer metal fitting and covers the space between the outer metal fitting and the inner metal fitting.

Embodiments of this invention will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 3 and 4, a change control unit 13 is attached to an insertion hole 12 provided in a floor panel 11 of the passenger compartment, and a change lever 14 of the change control unit 13 is attached to the lower end of the change lever 14. , the control rod 15 of the vehicle exterior transmission is connected.

The change control unit 13 includes a rectangular substrate 16, as shown in FIG.
An annular large-diameter outer metal fitting 1 is disposed within the central circular opening of the substrate 16.
At the same time, bolts 18, . The board 16 is attached to the floor panel 11 by placing it against the panel 11 and screwing nuts 20, . . . , 20 onto the bolts 18, . . . , 18 from above the floor panel 11.

Inside the outer fitting 17 is an annular small diameter inner fitting 21.
hollow parts 22, 2 that make the inner surface of the outer metal fitting 17 and the outer surface of the inner metal fitting 21 hard in the select direction of the change lever 14 and soft in the shift direction.
The mount rubber 23 formed with 2 is connected by baking or the like.

As shown in FIGS. 6 and 7, the mount rubber 23 includes a thin inner ring portion 23a extending upward along the outer surface of the inner fitting 21, and a thin inner ring portion 23a extending upward along the inner surface of the outer fitting 17. outer ring part 23
This is a structure in which the parts b are integrally connected.

An outward engaging protrusion 23c is formed on the upper part of the inner ring 23a, and the outer ring 23
An outward engaging protrusion 23d that protrudes from the outer surface of the outer metal fitting 17 is formed on the upper part of b.

A holder 26 that supports a ball seat 25 that supports the ball joint portion 24 of the change lever 14 is fitted into the inner fitting 21 with a spring 27 compressed between it and the upper part of the inner fitting 21. At the same time, an extension bar 29 is connected to the lower bracket 28 of the holder 26.

It is mounted astride the engagement protrusion 23c of the mount rubber 23 on the upper part of the inner metal fitting 21 and the engagement protrusion 23d of the mount rubber 23 on the upper part of the outer metal fitting 17,
A boot 30 is provided to tightly seal between the inner metal fitting 21 and the outer metal fitting 17.

With the boot structure described above, both the mount rubber 23 and the mount rubber boot 30 have simple shapes, so the molding mold is simple, and the number of pieces that can be molded simultaneously in one molding process can be increased. .

In addition, with respect to the swinging of the change lever 14, the mount rubber 23 is hard in the select direction and soft in the shift direction, so that erroneous gear shifting operations can be prevented.

Furthermore, the outer metal fitting 17 and the inner metal fitting 21 are connected to each other by the boot 30.
(that is, the insertion hole 1 of the floor panel 11
2) Since it can be kept tightly sealed, it can block out sound, water, and air from outside the vehicle. This boot 30 as a separate part is
Engagement protrusion 23 formed using mount rubber
Since it is attached to both metal fittings 17 and 21 by c and 23d, its structure is simple. It goes without saying that if the upper end of the outer metal fitting is bent outward, the mount rubber boot can be more securely engaged with the outer metal fitting. Furthermore, in the above embodiment, the engaging protrusion formed by extending the mount rubber upward is provided on both the inner and outer metal fittings 21, but the outer metal fitting has a relatively large outer diameter and is easy to bend. If the upper end is bent outward without providing an engaging protrusion integral with the mount rubber, and the outer peripheral part of the boot is engaged and held at this bent part, the outer engaging protrusion can be omitted.

As is clear from the above description, this invention uses a mount rubber that connects the outer metal fitting on the floor panel side and the inner metal fitting on the shift lever side to form an engaging protrusion, and the engaging protrusion has a Since the boot that seals between the outer metal fitting and the inner metal fitting is locked and attached, the structure for attaching the boot is simple, and the manufacturing process can be reduced, resulting in a significant cost reduction.

Further, effects such as preventing erroneous gear shifting operations, reducing transmission of vibration to the vehicle body, and keeping the insertion hole of the floor panel airtight can also be achieved.
