Abstract
When a knee airbag is deployed, a lid, which is provided in a column cover that covers a steering column, is opened by the deployment pressure of the knee airbag. Thus, an opening, through which the knee airbag expands, is formed to extend in the lower wall portion and the right and left side wall portions of the column cover. At this time, an opening amount regulation portion regulates the opening amount of the lid so that the knee airbag is deployed toward areas on right and left sides of the column cover.
