According to a fourth aspect of the present invention, in any one of the first to third aspects of the present invention, the engaging portion provided on the edge of the inner hole of the boot holding plate and the engaging portion provided on the lower inner side of the upper boot are circular. It is characterized by being formed in an annular shape.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, the shift lever 1 protrudes from the opening 2 a of the vehicle body floor 2 toward the vehicle interior, and a costume boot 3 is mounted. The shift case 7 of the shift lever 1 faces the opening 2 a of the vehicle body floor 2, the upper surface of the shift case 7 is made substantially coincident with the surface of the vehicle body floor 2, and a plate 8 is mounted on the upper surface of the shift case 7.

As shown in FIGS. 1 to 4, the gap between the shift case 7 of the shift lever 1 and the opening 2 a of the vehicle body floor 2 is closed by the base boot 4. A bolt hole 4d is formed in the outer peripheral flat portion 4c of the base boot 4. Further, the base boot 4 is formed with a contact portion 4e that rises from the inside of the outer peripheral flat portion 4c to the inside of the vehicle compartment, and an inner hole edge 4f having a groove 4a. The contact portion 4e has a substantially cylindrical shape in the rising shape portion.

The base boot 4 and the metal boot holding plate 11 are integrally formed by vulcanization molding, and the boot holding plate 11 is bonded at the outer peripheral flat portion 4c of the base boot 4. The boot holding plate 11 comes into contact with the cylindrical contact portion 4e of the base boot 4, and the upper portion of the boot holding plate 11 projects away from the contact portion 4e of the base boot 4 toward the vehicle interior, and the tip is bent outward. The engaging portion 11a, which is directed directly to the vehicle body floor 2 and has a substantially inverted J-shaped cross section, is formed in an annular shape. Also, the boot holding plate 11
A base boot shape regulating surface 11b for regulating the shape of the base boot 4 is formed on the vehicle body floor 2 mounting side, and the end of the base boot shape regulating surface 11b prevents the base boot 4 from being crushed due to excessive tightening of the bolt 10 during mounting. For the car body floor 2
Is provided with a stopper flange 12. Also,
The opening 2a of the vehicle body floor 2 has a flange formed on the periphery thereof to assist the positioning of the base boot 4. The boot holding plate 11 integrally provided by vulcanization molding has bolt holes 11c at the same positions (four corners) as the base boot 4.

The upper boot 5 has a shift lever 1 at the edge of the inner hole.
And a boot holding plate 1 on the outer peripheral edge.
An engaging portion 5b that engages with one engaging portion 11a is formed. In FIG. 1, the bellows of the upper boot 5 has a substantially flat shape, but the external shape can be changed at the position where the engaging portion 5 a is attached to the shift lever 1. As shown in FIG. 2, the opening 2 a of the vehicle body floor 2 is formed in a square shape, and the vulcanized base boot 4 and the boot holding plate 11 are placed on the upper surface thereof and tightened with bolts 10. The upper boot 5 is further assembled upward by engaging with the engaging portion 11a of the boot holding plate 11 by the engaging portion 5b.

With the above-described structure, the hole position of the mounting bolt is conventionally adjusted when the base boot 4 and the annular plate 9 are overlapped and fixed, or when the base boot 4 and the upper boot 5 are overlapped and fixed. Was complicated,
Since the base boot 4 and the boot holding plate 11 are integrated by vulcanization molding, it is advantageous in the following points. First, the integration facilitates alignment and simplifies assembly work. In addition, since the base boot 4 alone is made of a relatively soft rubber member and has no rigidity, it is difficult to align the holes of the boot alone, but in the present invention, the base boot 4 is a rigid boot holder. Since it is integrated with the plate 11, the shape is maintained and the assembling work is facilitated. Also, the number of parts can be reduced by integration. Further, when fastening the outer peripheral flat portion 4c of the base boot 4, excessive deformation can be prevented by the rigid boot holding plate 11 and the stopper flange 12, and the durability of the base boot 4 is improved.

Next, the engaging portion 11a of the metal boot holding plate 11 can be easily formed, and this engaging portion 11a is engaged with the engaging portion 5b of the flexible upper boot 5, so that it is fastened together. There are no places, so that the boots can be prevented from rubbing each other due to the movement of the transmission and the shift lever 1, and the generation of abnormal noise can be prevented.

With regard to the insertion of the upper boot 5, the engagement portion 1
Since the first boot 1a is formed in a substantially round shape, the upper boot 5 is easily inserted without being caught, and the upper boot 5 is prevented from being damaged by the engaging portion 11a. Conversely, in the pulling-out direction of the upper boot 5, the engaging portion 5b of the upper boot 5 is hooked on the end of the engaging portion 11a, so that the upper boot 5 can be reliably prevented from coming off. In addition, boot holding plate 1
Since the protrusions 1 protrude into the vehicle cabin, the attachment of the upper boots 5 is improved, and the rigidity of the boot holding plate 11 prevents the upper boots 5 from coming off due to deformation of the upper boots 5.
The workability is improved because the joint portions are separated in this way to eliminate the co-tightening. Further, since the joint fastening is eliminated, no bolt hole is required, and there is no hole shape.
Is almost completely circular and has no directionality, so that the assembly can be smoothly performed without being affected by the positions and angles of the vehicle body floor 2 and the shift case 7, which contributes to both reduction of man-hours and cost reduction.

Even when the height position of the vehicle body floor 2 and the height position of the shift case 7 are different from each other in the upper and lower directions, the same effect can be obtained by changing only the shape of the base boot 4. Further, since the mounting portion of the upper boot 5 is exposed in the vehicle interior, it is not necessary to separately provide a fixing member for the upper boot 5, and the number of parts is reduced and the assembling property is improved.

Although it is necessary to take measures against gaps and the like in each of the engaging portions, since the boot holding plate 11 is provided with an annular engaging portion, it is difficult to form a gap with the upper boot 5 so that sound insulation and noise can be reduced. This ensures the prevention of grease scattering.

[0022]

The present invention is as described above. According to the first aspect of the present invention, the base boot is mounted between the holding portion of the operation lever and the opening of the vehicle body floor, and the boot integrated with the base boot is provided. A holding plate is attached to an opening edge of the vehicle body floor, and an upper boot is engaged with the operation lever and is engaged with the boot holding plate. Therefore, the base boot and the upper boot do not interfere with each other without being fastened together by the boot holding plate, and
The assembly can be easily performed without being affected by the height relationship between the vehicle body floor and the holding portion of the operation lever.

According to the second aspect of the present invention, since the engaging portion of the boot holding plate only bends the sheet metal, it can be easily formed. The upper boot is externally inserted into the boot holding plate and the engaging portions of the two are engaged with each other, so that the upper boot can be easily mounted. At the time of mounting, the deformation of the upper boot can be prevented by the rigidity of the boot holding plate.

According to the third aspect of the present invention, since the base boot and the boot holding plate are integrally assembled by bonding, the base boot can be prevented from being deformed and can be easily arranged at the mounting position. Further, since no separate fixing parts are used, the assembling property is good and the number of parts is reduced. According to the fourth aspect of the present invention, since the engagement portion between the boot holding plate and the upper boot is formed in an annular shape, it is not necessary to consider the direction at the time of mounting, the assembly can be easily performed, and the gap between the two members can be easily achieved. Also, it is difficult to form sound, so that sound insulation and prevention of grease scattering can be achieved.
