Abstract

PURPOSE:To cut production cost by forming a boot so that the upper edge supporting part of the boot can cope with the variation of the shaft diameter of a shift lever, thus providing the versatile use performance for the boot. CONSTITUTION:When a boot B is installed onto the shaft part 10 at the desired position of a shift lever S, the basic part 3 at the lower edge of the boot B is installed onto the peripheral edge of an opened part 2, and then the shift lever S is projected from the opened part 2. At this time, a lip part 9 is elastically attached in a little outwardly deflected state onto the shaft part 10. When an upper edge supporting part 4 is outside-fitted onto a bulged part 6, the upper edge supporting part 4 is fitted onto the shaft part 10, and the lip part 9 is hooked once at the upper edge inclined part 11 position of the bulged part 6. When the shift lever S is pulled-up further from the above-described state, the lip part 9 is easily turned up, since the lip part 9 is formed thin, and the back surface of the lip part 9 is elastically attached onto the outside peripheral surface of the bulged part 6.

Description

[Detailed description of the invention] The present invention relates to an improvement in a shift lever boot.

Generally, the shift lever in floor shift type has
A dustproof boot is installed to prevent water and dust from entering the passenger compartment through the opening for protruding the shift lever provided in the floor, and to block the opening to prevent engine noise and other noise. It is set up. This boot B conventionally has a lower end base 3 that is fitted and fixed to the periphery of an opening 2 provided in a floor 1 as shown in FIGS. 1 and 2;
A bellows portion 5 is provided between the shift lever 8 protruding from the opening 2 and an annular upper end support portion 4 which is fitted onto the outside and comes into elastic contact with the shift lever 8, and the entirety is made of rubber or other elastic material. This allows it to expand and contract.

However, in such conventional boots B,
For example, as shown in FIG. 2, or as shown in FIG. 2, a bulge 6 filled with an elastic material such as rubber is formed inside to improve the vibration damping properties of the shift lever S. The shaft diameter of the shifter 8-5 differs depending on the vehicle model, and the L end support part 4 of the boot B is formed to correspond to these shaft diameters. I had to. For this purpose, conventionally the shift lever 5
It is necessary to stock a number of types of boots B corresponding to the shaft diameters of the boots B, and there is a problem in that the lack of versatility leads to an increase in manufacturing costs.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to form the upper end support portion of the boot so as to be able to respond to changes in the shaft diameter of the shift lever. This is an attempt to reduce manufacturing costs by making the boots more versatile. The gist of the present invention is to provide the upper end support part of the boot that is fitted onto the shift lever with a flexible annular lip part that is bent inward from the upper part of the upper end support part, and when the boot is attached, the lip part is bent inwardly. The shift lever is bent in accordance with the shaft diameter of the shift lever and is supported in contact with the shift lever.

The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

FIG. 3 shows an embodiment of the present invention. The boot B according to this embodiment has a thick-walled lower end base 3 having an outward fitting groove 7 that is fitted into the periphery of an opening 2 provided in a floor 1, and a boot B that protrudes from the opening 2, as in the conventional case. A bellows part 5 is provided between the shift lever 5 and the upper end support part 4 which is fitted onto the outside of the shift lever 5, and the bellows part 5 is made expandable and retractable because the whole is made of rubber or other elastic material. Unlike the conventional case, the upper end support part 4 includes a truncated conical cylinder part 8 formed with a slightly larger diameter to accommodate various shaft diameters of the shift lever 8, and an upper edge of the cylinder part 8. and an annular lip portion 8 that is bent inside the cylindrical portion 8.

Therefore, the boot B having the above-mentioned configuration can be used, for example, as shown in FIG. 4 and FS5, with different shaft diameters.
When attaching to each type of shift lever 9, when attaching to the shaft portion 10 of the shift lever 8 at a desired position as shown in FIG.
is fitted, and then the shift lever 5 is made to protrude from the opening 2. At this time, the cutter/seven knob portion 8 comes into elastic contact with the shaft portion 10 while being slightly bent outward, and comes into close contact with the outer peripheral surface of the shift lever, thereby preventing dust, noise, etc. from entering from outside the vehicle. . Further, as shown in FIGS. 5 and 6, when the upper end support part 4 of the boot B is fitted onto the bulge 6 provided on the shift lever 9, the lower end of the boot B is first fitted as in the previous embodiment. After fixing the base 3, the shift lever 5 is made to protrude from the opening 2. At this time, as shown in FIG. 5, the upper end support part 4 is first fitted into the shaft part 10 of the shift lever 8, and the lip part 9 is once caught at the upper end inclined part 11 of the bulge part 6. When the shift lever 6 is further pulled upward from this state, 1) Since the knob part 8 is formed thin, it easily follows the shaft diameter of the bulge part 6 as shown in FIG. It is turned upward, and the back surface of the turned-up lip part 9 comes into elastic contact with the outer peripheral surface of the bulge part 8. As a result, no gap is formed between the lip portion 9 and the bulging portion 6, thereby reliably preventing dust and the like from entering the vehicle interior.

In addition, when the lip portion 9 is turned up, the opening formed by the lip portion is larger than the state shown in FIG.
The insertion workability is good.

As shown in FIG. 6, even if the entire lip portion 9 does not turn up, the lip portion 8 bends and follows the diameter of the bulge portion 6 or the shaft portion 10, so that it can be used with various shaft diameters. The shift lever 8 can be provided with versatility. Also,
Since the tip of the lip portion 9 does not come into contact with the shift lever 8, but contacts inward from the tip, the lip portion 9 has good durability against tearing.

As explained above, according to the shift lever boot according to the present invention, the upper end support part of the boot follows changes in the shaft diameter of the shift lever and can be brought into close contact with the outer circumferential surface of the shift lever. There is no need to stock a large number of boots corresponding to the shaft diameter of the shift lever, which reduces boot manufacturing costs, and also simplifies manufacturing management by standardizing boot specifications. can be achieved. .
