ブーツ構造の改良に関するものである。[Detailed Description of the Invention] This invention relates to an improvement of the boot structure of a change control for an automobile.

つた。 Conventionally, as shown in FIG. 1a, a bracket 4 incorporating a change control unit 3 such as a change knob 2 is fixed to a floor panel 1 of a vehicle body.
At the bottom of the bracket 4, there is a boot structure in which a dust boot 5 that surrounds the lower part of the unit 3 and blocks water, dust, etc. from under the vehicle is fixed with screws 6, but fixing with the screws 6 is troublesome. For this purpose, as shown in FIG. 1b, on the entire inner circumference of the upper part of the dust boot 5,
A boot structure has been proposed in which an inward flange 7 is formed to fit around the outer periphery of a large bracket 4, but the dust boot 5 becomes large, and because of its large size, it flexes greatly and easily falls off. There was a problem that the dust properties tended to be uncertain because of the long length.

定間隔ｔを隔てる一対の外向き切り起こし突起１
１ｂ，１１ｂを形成する。 This invention solves the above-mentioned conventional problems by simply adding a slight modification to the fitting structure of the dust boot to the bracket, and this can be explained with reference to the attached drawings. As shown, opposing side walls 11 of a downwardly bulging bulge 11 formed in the central portion of the bracket 10
a, 11a, a pair of outward cut and raised protrusions 1 separated from the lower surface 10a of the bracket 10 by a predetermined distance t.
1b and 11b are formed.

一方、上記膨出部１１の外周を囲撓するに足り

ツ１２の上部全内周に、ブラケツト１０の下面１
０ａと突起１１ｂ，１１ｂとの間に嵌合する内向
きつば１２ａを形成する。 On the other hand, a small rubber dust boot 12 sufficient to surround the outer periphery of the bulge 11 is provided, and the lower surface 1 of the bracket 10 is provided on the entire inner periphery of the upper part of the boot 12.
An inward flange 12a that fits between the protrusion 0a and the protrusions 11b, 11b is formed.

しかして、上記ダストブーツ１２は、その内向
きつば１２ａをブラケツト１０の突起１１ｂ，１
１ｂに嵌合することにより固定することができ、
膨出部１１の外周及び突起１１ｂ，１１ｂの抜き
穴は内向きつば１２ａで完全にシールされる。 Thus, the dust boot 12 has its inward flange 12a aligned with the protrusions 11b, 1 of the bracket 10.
It can be fixed by fitting into 1b,
The outer periphery of the bulging portion 11 and the holes of the protrusions 11b, 11b are completely sealed by the inward flange 12a.

以上のように、この考案は、ブラケツトの膨出

る。 As described above, in this invention, the inward collar of the rubber dust boot is fitted between the cut and raised protrusion formed on the side wall of the bulging part of the bracket and the lower surface of the bracket. The dust boot is miniaturized, its deflection can be minimized and there is no fear of it falling off, and the fitting length with the bracket is short, ensuring reliable dust resistance.

また、小型のダストブーツの他、膨出部に突起
を形成するだけであるから、構造はきわめて簡単
でコスト安に製作することができる。 In addition to the small dust boot, since only a protrusion is formed on the bulge, the structure is extremely simple and can be manufactured at low cost.

Claims

[Scope of Claim for Utility Model Registration] In the boot structure of an automobile change control, which has a dust boot at the bottom of a bracket incorporating a change control unit such as a change knob in the floor panel of the vehicle body, At least a pair of outwardly cut and raised protrusions are formed on the side wall of the bulging portion that bulges out, and are spaced from the lower surface of the bracket by a predetermined distance, and the upper entire inner periphery of the rubber dust boot that surrounds the outer periphery of the bulging portion is formed. A boot structure for a change control for an automobile, characterized in that an inward collar is formed that fits between the lower surface of the bracket and the protrusion.
