Description

[Detailed description of the invention] Industrial application field This invention relates to a shift lever boot for vehicles such as automobiles.

Conventional technology The fourth shift lever boot for conventional vehicles
As shown in the figure, the shift lever boot 11 is made of synthetic resin and has a bellows portion 12 and is relatively thick.

Problems to be solved by this invention This conventional shift lever boot for vehicles is the fifth
As shown in the figure, when the position of the shift lever shaft 14 is changed during a shift, the repulsive force F applied to the shaft 14 is large due to the thick wall of the boot. This has the disadvantage that a shift may be missed, and the compressed inner surfaces of the boot 11 rub against each other due to vibrations during driving or idling, causing abnormal noise. Since the shaft 14 and the bellows part 12 of the boot 11 are in surface contact with each other, there is a drawback that vibrations occur during running or idling, or friction occurs when changing the position of the shaft 14, causing abnormal noise. .

This invention eliminates these drawbacks of conventional vehicle shift lever boots, and prevents the shift lever shaft from shifting while driving, and also prevents the shift lever shaft from slipping off while driving. The purpose of this is to prevent abnormal noises from occurring even when the bellows part of the boot rubs against the bellows part of the boot.

Means for Solving the Problems The shift lever boot for a vehicle of this invention has a thin wall thickness, and a plurality of shift lever boots are provided continuously in the vertical direction from the mouth of the shift lever boot along the inside of the bellows part. The bellows part of the shift lever boot has a projecting rib, and the wall thickness of the bellows part and the projecting rib of the bellows part is gradually thinned from the trough to the peak part of the bellows part.

Function: The shift lever boot for a vehicle of this invention has a thin wall thickness and has a plurality of protruding ribs that are continuously provided in the vertical direction from the mouth of the shift lever boot along the inside of the bellows part. , and the thickness of the bellows part of the shift lever boot and the protruding ribs of the bellows part are gradually thinned from the valley to the peak of the bellows part. As a result, the shift lever boot has the necessary strength to stand on its own, and the wall thickness is thin, and the thickness gradually decreases from the valley to the peak of the bellows part, which reduces the repulsion that is applied to the shift lever shaft when the shift lever position is changed. The small force prevents the shift lever shaft from shifting. Furthermore, the compressed inner surfaces of the shift lever boot do not come into surface contact with each other, and the noise is prevented from being generated due to linear contact between the protruding ribs or between the protruding ribs and the inner surface of the boot. This prevents abnormal noise from occurring due to line contact with the protruding ribs at the boot mouth.

Embodiments Next, embodiments of the vehicle shift lever boot of this invention will be described with reference to the drawings.

As shown in FIGS. 1 to 3, a synthetic resin automobile shift lever boot 1 has a bellows part 2, and this boot 1 has a thin wall and runs along the inside of the bellows part 2 from the mouth of the boot. Eight protruding ribs 3 are integrally formed and are continuously provided in the vertical direction.

Further, in the shift lever boot 1 for an automobile, the thickness of the bellows part 2 and the protruding rib 3 of the boot 1 is gradually reduced from the valley part 2' to the peak part 2'' of the bellows part 2.

The above can be made most efficiently by blow molding a parison that has a plurality of ridges formed inside it as it passes through a die.

By using the automobile shift lever boot 1 of this embodiment by inserting the shift lever shaft 4 into the boot opening and fixing it to the floor of the automobile (not shown), the boot 1 can be made thinner overall. Regardless, the eight protruding ribs 3 allow the boot to stand on its own with the required strength, and the wall thickness of the boot is made thinner, and the wall thickness of the bellows part and the protruding ribs of the bellows part are reduced to the valley of the bellows part. Since the thickness is gradually reduced from the top to the top, when the position of the shift lever shaft is changed as shown in FIG. 2, the repulsive force applied to the shaft 4 is small, thereby preventing the shift lever shaft from shifting. Furthermore, the compressed inner surface of the boot prevents abnormal noise from occurring due to linear contact between the protruding ribs or between the protruding ribs and the inner surface of the boot. Prevents abnormal noise from occurring due to line contact.

Effects of the invention The shift lever boot for a vehicle of this invention has a thin wall thickness of the shift lever boot, has a plurality of protruding ribs on the inside of the shift lever boot, and has a bellows part of the shift lever boot and protrusions on the bellows part. Since the thickness of the rib is gradually reduced from the trough to the peak of the bellows part, the shift lever shaft and the protruding rib at the boot opening come into linear contact, preventing the shift lever shaft from sliding inside the boot opening. In addition, since the thickness of the boot is thin, the repulsive force applied to the shaft when changing the position of the shift lever shaft is small, and it is possible to prevent the shaft from shifting. Furthermore, the compressed inner surface of the boot can prevent abnormal noises from occurring due to linear contact between the protruding ribs or between the protruding ribs and the inner surface of the boot. This can prevent abnormal noise from occurring due to wire contact.
