摘要： An instrument panel of a vehicle mounts a cluster gauge and is formed with an opening through which a collapsible steering shaft projects. A steering end cover, formed as a hollow shell, is generally cylindrically shaped and covers an end portion of the collapsible steering shaft projecting above the instrument panel. A guide member, provided so as to overlap the opening, has a surface for guiding the hollow shell to sink or telescope into the opening when the collapsible steering shaft axially collapses during a front end, head-on collision.
