[0034] Hereinafter, with reference to the attached drawings, a temporary mounting structure for a steering shaft of a vehicle according to an embodiment of the present invention will be described in detail.
[0035] FIG. 2 is a drawing showing a temporary mounting structure for a steering shaft of a vehicle according to one embodiment of the present invention, FIG. 3 is a cross-sectional view taken along line AA of FIG. 2, and FIG. 4 is a drawing showing a view taken in a direction perpendicular to line BB of FIG. 3.
[0036] Referring to FIGS. 2 to 4, a temporary mounting structure for a steering shaft of a vehicle according to one embodiment of the present invention is a structure for temporarily mounting a steering shaft (10) of a vehicle connected by a yoke (12) by inserting it into a vehicle bulkhead (20), and includes a bulkhead (20) and a dust cover (30).
[0037] The bulkhead (20) is mounted across the surface of the dash panel (8) and housing (9) inside the vehicle and surrounds the engine room, and has an opening (21) formed into which the steering shaft (10) is inserted. The opening (21) is open toward the lower side of the vehicle body and the steering shaft (10) is inserted before the engine is mounted in the engine room.
[0038] A retaining projection (24) is formed in the bulkhead (20) to support the end of the yoke (12) so that it does not detach downward from the vehicle body after the steering shaft (10) is inserted. The retaining projection (24) is formed to protrude from the opening toward the outside of the bulkhead (20).
[0039] Additionally, the bulkhead (20) further includes a support surface (22) that supports the upper surface of the yoke (12) of the steering shaft (10). The support surface (22) may be formed to protrude from the opening (21) toward the inside of the bulkhead (20). The upper surface of the yoke (12) may be supported by contacting the lower surface of the support surface (22).
[0040] The dust cover (30) is inserted into the bulkhead (20) and forms an insertion passage for the steering shaft (10) corresponding to the opening (21) of the bulkhead (20). The dust cover (30) has a support point (32) formed therein to support the steering shaft (10) when the steering shaft (10) is inserted. The support point (32) is formed on the lower side of the dust cover (30) at a predetermined distance from the opening (21), and the lower part of the steering shaft (10) can be supported by contacting the support point (32).
[0041] That is, when the steering shaft (10) is inserted through the opening (21) of the bulkhead (20) and inserted into the interior of the bulkhead (20) and the dust cover (30), the yoke (12) attempts to move upward due to gravity, and the steering shaft (10) on the inserted side attempts to move downward. At this time, the upper surface of the yoke (12) of the steering shaft (10) is supported on the lower surface of the support surface (22), the end of the yoke (12) is supported on the catch (24), and the lower part of the steering shaft (10) is supported on the support point (32) formed on the lower side of the dust cover (30). Thus, the steering shaft (10) can be supported so as not to deviate downward from the vehicle body after being inserted into the opening (21).
[0042] A first rotation-prevention guide portion (26) supporting the upper end of the yoke (12) may be formed at the upper end of the opening (21) of the bulkhead (20) to prevent rotation around the axis center after the steering shaft (10) is inserted. Additionally, to prevent oscillation of the steering shaft (10) in the left and right directions, a first left and right fixing guide portion (28) supporting both sides of the yoke (12) may be formed between the first rotation-prevention guide portion (26) at the upper end of the opening (21) of the bulkhead (20), with a height protruding toward the outside of the opening (21). Thus, rotation and left and right oscillation can be prevented after the steering shaft (10) is inserted into the opening (21).

[0045] The catch (44) formed on the bulkhead (40) is formed to protrude toward the inside of the bulkhead (40). In this embodiment, the steering shaft (10) is inserted in a direction rotated approximately 90° relative to the insertion direction of the steering shaft (10) of the embodiment described with reference to FIGS. 2 to 4.
[0046] After the steering shaft (10) is inserted into the bulkhead (40), the end of the yoke (12) is supported by being mounted on the catch (44) so as not to detach downward from the vehicle body. Thus, the steering shaft (10) can be supported so as not to detach downward from the vehicle body after being inserted into the opening (41).
[0047] Additionally, a second rotation-prevention guide (46) supporting the upper end of the yoke (12) may be formed at the upper end of the opening (41) of the bulkhead (40) to prevent rotation of the steering shaft (10) around its axis. Furthermore, to prevent oscillation of the steering shaft (10) in the left and right directions, a second left and right fixing guide (48) supporting both sides of the yoke (12) may be formed between the second rotation-prevention guide (46) at the upper end of the opening (41) of the bulkhead (40), with a height protruding toward the center of the opening (41). Thus, rotation and left and right oscillation can be prevented after insertion of the steering shaft (10) into the opening (41).
[0048] That is, the steering shaft temporary mounting structure according to the embodiment of the present invention is characterized in that, unlike the steering shaft temporary mounting structure of the embodiment described with reference to FIGS. 2 to 4, which includes a stopper (24) protruding outside the partition wall (20), a first rotation prevention guide part (26), and a first left and right fixing guide part (28), the stopper (44) protrudes inside the partition wall (40), and the second rotation prevention guide part (46) and the second left and right fixing guide part (48) do not protrude outside the partition wall (40) and form the shape of an opening (41) of the partition wall (40).
