FIGS. 5A and 5B are explanatory diagrams (first half) of the operation of the seal structure according to the present invention. FIG. 5A is a view showing an erroneous operation, in which the steering gear case 7 to which the sealing member 20 is attached in advance is attached to the opening 11 of the body panel 11.
When inserted into a from below, the following problem occurs. That is, when the steering gear case 7 is positioned, an operation of inclining the main shaft A occurs.
When working with the conical lip 22 down on one side,
There is a possibility that the conical lip portion 22 may bite or be damaged. Then, the following (b) and FIG.
Perform the work as shown in (a) and (b).
