[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever boot for covering a shift lever for performing a shifting operation of a transmission of an automobile.

[0002]

2. Description of the Related Art A conventional shift lever boot is constructed as follows. That is, as shown in FIG. 5, a shift lever 2 is formed on the outer periphery of the shift lever 2 in a substantially truncated conical shape, with both end portions serving as attachment portions 6a and 6b, and a bellows portion 3 between the attachment portions 6a and 6b. A lever boot 1 is provided. Of the mounting portions 6a and 6b at both ends, a small-diameter mounting portion 6b located at the upper portion is attached to the shift lever 2, and a large-diameter mounting portion 6a located at the lower portion is attached to the vehicle body 8.

When the shift lever 2 is tilted, as shown by a two-dot chain line in FIG.
The bellows portion 3 tilts in the tilting direction (left direction in the figure) of the shift lever 2 because the mounting portion 6b at the upper end moves integrally with the shift lever 2, and the tilting side of the bellows portion 3 is pushed. Shrunk.

[0004]

At the position adjacent to the shift lever boot 1, a console 7 as another component is disposed at an upper position or a lower position so as not to interfere with the shift lever boot 1. . Therefore, the position where the console 7 is disposed is the shift lever boot 1.
The console 7 must be set so as not to interfere with the shift lever boot 1 even when the bellows portion 3 of the vehicle is tilted most.

However, the bellows 3 of the shift lever boot 1
Since the distance between the peaks 5a and 5b or the distance between the valleys 4a and 4b is constant, the bellows 3 in the direction in which the shift lever boot 1 is tilted is uniformly compressed. Therefore, in order to avoid interference with the bellows part 3, the console 7 must be disposed at a position separated from the position where the bellows part 3 is most inclined, that is, at a side position of the bellows part 3 or a position above the bellows part 3. become. Therefore, there is a problem that the position where the console 7 is installed is restricted and a space for the console 7 is required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has as its object the possibility of interfering with other adjacent components, and disposing other components at a position as close as possible. Another object of the present invention is to provide a shift lever boot that can save space.

[0007]

In order to achieve the above object, according to the present invention, a bellows portion is formed so as to cover an outer peripheral portion of a shaft, and one end of the bellows portion is attached to the shaft. Re Rutotomoni, mounting et on the other end of the bellows part is the body
Is, the shaft is a shift lever boot the bellows portion is deformed by tilting, the bellows portion
Of the plurality of valleys having the body when the shaft is tilted.
To the other parts adjacent to the bellows
A shift lever boot in which the radius of the arc of the specific valley closest to the valley is formed larger than the radius of the arc of the other valley so that the specific valley does not interfere with other parts due to deformation of the bellows. And

[0008]

[Function] In the shift lever boot of the present invention,
When the shaft is tilted, the radius of the arc is larger than that of the other valleys.
The strength of the particular valley formed is increased and the resistance to deformation increases, and the deformation at the particular valley decreases, thereby maintaining a certain space. Therefore, this
Even if another component is arranged adjacent to a specific valley, there is no possibility that the other component will interfere with the bellows portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The description of the same parts as those in the conventional example described above is omitted, and different parts will be mainly described. The same reference numerals are used for the same members. As shown in FIG. 2, the radius R of the arc forming the lowermost valley 4a of the bellows portion 3 where the console 7 is disposed is formed to be larger than the radius r of the arc forming the other valleys 4b. ing. The ridges 5a, 5b on both sides of the valley 4a are formed such that the distance between the ridges 5a, 5b increases on the extension of the arc forming the valley 4a. The valley 4a and the ridges 5a, 5b on both sides thereof
Is formed large so that the front end of the console 7 can be accommodated.

In the bellows portion 3 , the console 7
With respect to the position facing the tip, that is, the console 7
The closest when the shift lever 2 is tilted
By increasing the radius R of the valley 4a at the site (hereinafter referred to as an "interference site"), the tip of the console 7 can be accommodated in the space S formed by the valley 4a, When the shift lever 2 is tilted and receives a force to deform the bellows portion 3, the space portion S formed by the valley portion 4a is held in a constant state by receiving the force.

In the present embodiment, the radius R of the valley 4a is 1
The radius r of the other valleys 4b is more than twice as large as 4.5 to 5 mm. Preferably, the radius R of the valley 4a is in the range of 8 to 30 mm. If the radius R is less than 8 mm, the deformation of the valley portion 4a tends to be large, and it is difficult to accommodate the console 7 in the valley portion 4a. On the other hand, if it exceeds 30 mm, the bellows portion 3 itself must be enlarged. It is not preferable because it must be done.

The thickness D of the valley 4a at the interference site is formed to be larger than the thickness d of the other valleys 4b. As shown in FIG. 3, this thickly formed valley 4
The two interference parts a are two places on the left and right located close to the console 7. By making the thickness D of the valley portion 4a thicker than the thickness d of the other valley portion 4b, the strength of the portion is increased, and even if the bellows portion 3 receives a force that is going to deform, it resists the force. The shapes of the valleys 4a and the ridges 5a and 5b at the interference site can be maintained.

The thickness D of the valley 4a is preferably in the range of 1.8 to 3.0 mm, and the other valleys 4b are formed to be thicker than the thickness d of 1.5 mm. This thickness D is 1.8
If it is less than mm, the strength of the valley 4a is insufficient and the deformation tends to be large, and if it exceeds 3.0 mm, the thickness becomes excessive and the production cost tends to increase. The shift lever boot 1 is made of a soft and durable resin or rubber. As the resin, a soft vinyl chloride resin, as the rubber, chloroprene rubber (CR), ethylene-propylene-diene copolymer rubber (EPDM), and as a blend of the resin and the rubber, a soft vinyl chloride resin and an acrylonitrile-butadiene copolymer rubber (NBR) blends and the like are used.

Next, the operation of the shift lever boot 1 configured as described above will be described. As shown in FIG. 1, when the shift lever 2 is tilted to the left in the figure, the mounting portion 6 b of the shift lever boot 1 mounted on the shift lever 2 tilts in the same manner as the shift lever 2. Therefore, the distance between the mounting portions 6a and 6b of the bellows portion 3 in the tilting direction is shortened, and the bellows portion 3 is compressed.

At this time, the valley portion 4a of the bellows portion 3 located at a position facing the interference portion, that is, the tip portion of the console 7, has a radius R forming the valley portion 4a larger than the radius r of the other valley portions 4b. Since it is large, the deformation is prevented by receiving the force applied to the valley 4a, and a certain large space S formed by the valley 4a is held. In addition, since the thickness D of the valley 4a at the interference portion is formed to be thicker than the thickness d of the other valleys 4b, the strength of this portion is increased, and the force applied to the valley 4a increases. Becomes difficult to deform. Therefore, the force applied to the bellows portion 3 is absorbed by the portion other than the valley portion 4a in the interference portion. As a result, the large space S formed by the valley 4 a of the interference portion is sufficiently held so that the valley 4 a does not interfere with the tip of the console 7. Then, the console 7 can be arranged in the space S.

As described above, in the shift lever boot 1 of the present embodiment, the bellows portion 3 of the shift lever boot 1 and the console 7 may interfere with each other even if the adjacent consoles 7 are arranged as close as possible. There is no. Therefore,
The console 7 can be arranged at a position close to the shift lever boot 1, and the space can be saved correspondingly.

The present invention is not limited to the above embodiment, but may be embodied as follows, for example. (1) In the above embodiment, as shown in FIG. 3, the thickness D is increased only on the left and right sides at the interference position of the valley 4a.
It may be formed thick over the entire circumference. (2) In the above embodiment, only the thickness D of the valley 4a at the interference position is formed thicker, but as shown in FIG.
a and the ridges 5a and 5b on both sides thereof may be formed thick. With this configuration, the strength of the peaks 5a and 5b is improved, and deformation of the peaks 5a and 5b is prevented. Therefore, the space S formed by the valley 4a and the ridges 5a and 5b is held in a larger state. (3) In the above embodiment, the radius R of the arc of the valley 4a at the interference site is formed to be larger than the radius r of the arc of the other valley 4b, and the thickness D of the valley 4a is changed to the other valley. Although it is formed thicker than the thickness d of the valley 4b, the radius R of the arc of the valley 4a may be merely larger than the radius r of the arc of the other valley 4b.

[0018]

[Effect of the Invention] As described in detail above, according to the present invention,
Shaft above the body with bellows
Since there is no danger of the bellows part and other parts adjacent to the bellows part interfering with each other at the time of tilting, it is possible to arrange the other parts at a position as close as possible to the bellows part. This has the effect of saving space.
