(11) Hereinafter, a shift lever assembly according to exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

(12) FIG. 1 shows a shift lever assembly according to an exemplary embodiment of the present invention, FIG. 2 is a side view of FIG. 1, FIG. 3 is a plan view of FIG. 1, FIG. 4 is a cross-sectional view taken along the line A-A of FIG. 1, FIG. 5 is a cross-sectional view taken along the line B-B of FIG. 4, and FIG. 6 is a diagram illustrating in detail a coupling portion of FIG. 1. Further, FIG. 7 and FIG. 8 are views showing states before and after an elastic body 700 is inserted into an insertion hole 310.

(13) As shown in FIG. 1, FIG. 2, and FIG. 3, a shift lever assembly according to an exemplary embodiment of the present invention includes a shift lever housing 300 configured to have a shift lever 100 rotatably coupled thereto in a shift direction, a front and back direction of a vehicle, and a select direction, a left and right direction of a vehicle; a base bracket 500 configured to be coupled to the shift lever housing 300 and fixedly disposed on a vehicle body; and a fastening member 900 configured to extend in the shift direction to couple the shift lever housing 300 and the base bracket 500 to each other.

(14) The shift lever housing 300 is provided with a shift lever (100) for shifting the vehicle. A point where the shift lever housing 300 meets the base bracket 500 is provided with the insertion hole 310 which is open in the front and back direction of the vehicle. The insertion hole 310 may be a rectangular shape.

(15) The base bracket 500 is fastened with the shift lever housing 300 below the shift lever housing 300. In the base bracket 500, a position corresponding to the insertion hole 310 of the shift lever housing 300 is provided with the fastening hole 510 which is open in the front and back direction of the vehicle.

(16) The elastic body 700 is disposed between the fastening member 900 and the shift lever housing 300 or between the fastening member 900 and the base bracket 500. The elastic body 700 is inserted into the fastening hole 510. Although the elastic body 700 is shown to be fastened to the fastening hole 510 in the present embodiment, the elastic body 700 may also be disposed in the fastening hole 510 of the base bracket 500, and therefore the disposition location of the elastic body 700 is not limited. The elastic body 700 may include rubber, elastomer, or the like. FIG. 6, FIG. 7, and FIG. 8 show the elastic body 700 in detail. As shown in the drawings, in the elastic body 700 a position corresponding to the fastening hole 510 is provided with the through hole 710, and the through hole 710 is open in the front and back direction of the vehicle. The elastic body 700 may be a bushing. That is, the elastic body 700 is inserted into the insertion hole 310 of the shift lever housing 300, and the fastening hole 510 and the through hole 710 are positioned at the matched point thereof in the state in which the elastic body 700 is inserted into the shift lever housing 300.

(17) The elastic body 700 has a rectangular shape in which each edge portion is larger by L1 than the cross-sectional area of the insertion hole 310, in which each edge portion of the elastic body 700 is provided with at least one indentation groove 730. Forming the indentation groove 730 on a center side of the elastic body 700 may be the most effective for absorbing vibration or impact, but the position of the indentation groove 730 is not limited. At the central side of the elastic body 700, the indentation grooves 730 indented inwardly are formed at one or more edge portions. The indentation groove 730 has a hemispherical shape in which the front and back direction of the vehicle is a longitudinal direction, and is configured to prevent a vibration transmitted during the traveling of the vehicle from being transmitted to the shift lever 100.

(18) Since the elastic body 700 has a cross sectional area larger than that of the insertion hole 310, the elastic body 700 can be assembled in a pressed state. Therefore, a volume before the assembly is larger than that after the assembly. Therefore, the elastic body 700 is press-fitted in the up and down and left and right directions of the vehicle when being inserted into the insertion hole 310, increasing the shift and select rigidity of the shift lever 100. Further, the through hole 710 of the elastic body 700 is formed in a rectangular shape in which a round of R1 is formed on a vertex side has a width of L2 before assembling. However, after the press-fitting, the through hole 710 is compressed to become a circle having a diameter of D1. Therefore, it is possible to realize the quick fastening by pushing the fastening member 900 when the fastening member 900 is fastened, and keep robust fastening to prevent the fastening member 900 from being separated without a separate component.

(19) Further, the fastening member 900 simultaneously penetrates through the fastening hole 510 and the through hole 710 to fasten the shift lever housing 300 with the base bracket 500. The fastening member 900 may be a bar-shaped pin and the fastening member 900 is fastened to the shift lever housing 300 and the base bracket 500 simultaneously by setting the front and back direction of the vehicle to be the longitudinal direction thereof. Therefore, in the manual transmission, the rigidity in the front and back direction of the vehicle which is the shift direction is important at the time of a selection of a speed change stage. In an exemplary embodiment of the present invention, the fastening member 900 is fastened in the front and back direction of the vehicle to match the shift direction, wherein the fastening member 900 supports the rigidity in the shift direction when a user manipulates the shift, securing the rigidity.

(20) The fastening member 900 is disposed to have both end portions thereof penetrating through the shift lever housing 300 and the base bracket 500, respectively. The fastening member 900 is disposed to penetrate through the fastening hole 510 and the through hole 710 to be pressed by the elastic body 700, wherein the fastening member 900 may be supported without a separate fixing member. Therefore, there is an advantage in that the number of components in the structure can be reduced. The fastening members 900 are disposed on the right and left sides of the shift lever housing 300 and the base bracket 500, respectively, to be four-point fastened, wherein the fastening member 900 is formed in a rectangular shape, more stably keeping the fastening secure. Even when the fastening member 900 is pressed downwardly by a user at the time of operation of the shift lever 100, a pressing force is dispersed to four points, wherein the shift lever 100 can be supported more effectively. The fastening members 900 are disposed on the left and right sides of the shift lever housing 300 and the base bracket 500 while being separated apart from each other by a predetermined distance to secure a sufficient fastening region when the shift lever 100 and a transmission cable 800 are assembled, wherein the interference with the fastening member 900 does not occur, facilitating the assembling and increasing production efficiency.

(21) Therefore, according to the shift lever assembly having the structure as described above, the assembling can be made by the method for forming the insertion hole 310 in the shift lever housing 300 in the front and back direction of the vehicle, forming the fastening hole 510 on the base bracket 500 in the front and back direction of the vehicle, and fastening the fastening member 900 after the elastic body 700 provided with the through hole 710 is fastened with the insertion hole 310, minimizing the number of components to save costs, securing the rigidity of the shift and the select by the elastic body 700, and securing the assembly region for assembling the shift lever 100 with the transmission cable 800 to increase the productivity.
