Description

[Detailed Description of the Invention] This invention relates to a mounting structure for a dust boot for a shift lever in an automobile, particularly a dust boot integrally molded into a bellows shape.

As a conventional mounting structure for a dust boot for a shift lever, there is, for example, one shown in Japanese Utility Model Application Publication No. 56-141827 and shown in FIGS. 1 and 2. In the diagram, 1 is the center console box, 2 is the shift lever, and 3 is the center console box.
is a shift knob, 4 is a dust boot, and 5 is a boot holder. The center console box 1 has an opening 7 on the top surface 6 for protruding the shift lever 2.
It is installed on a floor tunnel 9 through which the propeller shaft 8 is inserted. The shift lever 2 projects from the opening 7 of the center console box 1 and is inclined at a constant angle θ with respect to the vertical direction X toward the rear of the vehicle (direction A in the figure). Dust boots 4 are rubber,
It is integrally molded in a bellows shape from an elastic material such as synthetic resin, and the upper end 10 is loosely fitted into the shift lever 2, and the lower end 11 is inserted into the opening 7 position of the upper surface 6 of the center console box 1 via the boot holder 5. I am trying to install it. This boot holder 5 is located at the opening 7 of the center console box 1.
The dust boot mounting portion 12 on the inside and the lower end 11 of the dust boot 4 have a frame plate shape approximately corresponding to the
are integrated in advance by heat caulking via the retainer 13. The boot holder 5 also has a console box attachment part 14 on the outside of the dust boot attachment part 12, and a claw 15 protruding from the console box attachment part 14 is attached to the edge 16 of the opening 7 of the center console box 1. It can be fitted freely.

However, in such a conventional shift lever dust boot mounting structure, the entire boot holder 5 is attached to the center console box 1.
Since the lower end 11 of the dust boot 4 is attached to the upper surface 6 of the center console box 1 via the boot holder 5, which is positioned substantially on the same plane as the upper surface 6, the lower end 11 of the dust boot 4 and the shift lever 2 are connected to each other. do not intersect perpendicularly, and the angle α of the shift lever 2 on the front side (direction B in the figure) with respect to the lower end 11 of the dust boot 4 is large, and the angle β on the side of the rear side (direction A in the figure) is small. As a result, the front side of the dust boot 4 is extended and the rear side is contracted, and the dust boot 4 is stretched when shifting [especially when rotating the shift lever 2 rearward (direction A in the figure)]. In addition to the fact that the rear side is difficult to bend and it is difficult to maintain the shape, the lower end 11 of the dust boot 4 is likely to separate from the boot holder 5 because an unreasonable tensile force is applied to the front side of the dust boot 4 in the rear direction. There was a problem. Therefore, it is conceivable to change the shape of the upper surface 6 of the center console box 1 to deal with the above-mentioned points. However, in this case, the height position of the upper end of the shift lever 2, that is, the shift knob 3, is limited by driving operability, and the height position of the floor tunnel 9 is limited by the minimum ground clearance of the propeller shaft 8 that passes through it. As a result, it is not possible to take enough space between the shift knob 3 and the floor tunnel 9, and in this limited space, the center console box 1 cannot be formed at a certain height to be placed in the center. The rigidity of the console box 1 must be maintained, and under such restrictions, if the shape of the top surface 6 of the center console box 1 is changed (particularly in the height direction), the rigidity of the center console box 1 will be changed. The problem was that the rigidity would be reduced, making it difficult to realize.

This idea was made by focusing on the problems of the conventional technology, and the dust boot mounting part of the boot holder is tilted and recessed toward the rear of the vehicle relative to the console box mounting part, and is approximately recessed relative to the shift lever. By making the console boxes intersect perpendicularly, the purpose is to solve the above-mentioned conventional problems while maintaining the rigidity of the console box.

This invention will be explained below based on the drawings. 3 to 5 are diagrams showing an embodiment of this invention. Incidentally, in the following, parts similar to those in the prior art will be indicated by the same reference numerals, and redundant explanation will be omitted.

In this mounting structure of the dust boot 4 for the shift lever 2, the lower end 1 of the dust boot 4 can be mounted without changing the shape of the center console box 1.
By changing the shape of the boot holder 17 for attaching the dust boot 4 to the upper surface 6 of the center console box 1, the mounting state of the dust boot 4 can be made to correspond to the inclined state of the shift lever 2 while maintaining the rigidity of the center console box 1. It is meant to be. That is, this boot holder 17 has a console box attachment part 19 formed in a flange shape from which a claw 18 protrudes that engages with the edge 16 of the opening 7 formed in the center console box 1. On the other hand, the dust boot mounting portion 20 is recessed downwardly at an angle γ from the front direction (direction B in the drawing) to the rear direction (direction A in the drawing), and the dust boot mounting portion 20 is attached to the shift lever 2. It is made to intersect approximately perpendicularly to the opposite direction. Therefore, this dust boot attachment part 2
The lower end 11 of the dust boot 4, which is integrated with the shift lever 2 in advance by heat caulking, also intersects the shift lever 2 approximately perpendicularly, similar to the dust boot mounting portion 20, and as a result, the dust boot 4 is attached to the shift lever 2. Corresponding to the inclination angle θ, even though the shift lever 2 is inclined toward the rear of the vehicle, it is possible to make the deflection allowance of the dust boot 4 substantially uniform on the front and rear sides of the shift lever 2. It is.

As explained above, according to this idea,
The configuration is such that the lower end of the dust boot, which is a bellows-shaped integral molded product whose upper end fits into the shift lever that projects from the upper surface of the console box at an angle toward the rear of the vehicle, is attached to the boot holder that attaches to the upper surface of the console box. We decided to form a dust boot attachment part that is inclined and recessed toward the rear of the vehicle and intersects the shift lever approximately perpendicularly to the console box attachment part, thereby maintaining the rigidity of the console box while maintaining the stability of the shift lever in the longitudinal direction. The amount of deflection of the dust boot during shifting can be made almost uniform, which eliminates the difficulty of deflecting the dust boot and maintaining its shape during shifting, unlike conventional methods, even though the shift lever is tilted toward the rear of the vehicle. In addition, it is possible to prevent the dust boots from peeling off from the boot holder due to excessive pulling force, and in addition, it is possible to improve the rigidity of the boot holder itself. Since it is located below the top surface of the box, the lower end of the dust boot is not exposed, resulting in a better appearance.
