Abstract: A column hole cover is interposed between a circumferential portion of an aperture of a column hole of an instrument panel and a steering gear box capable of being displaced in a predetermined direction. The column hole cover includes a cylindrical main body extended in the predetermined direction. The main body includes a first annular end portion directly or indirectly fixed to the steering gear box, and a second annular end portion. The second end portion is provided with an annular seal. An intermediate portion between the first and second end portions is provided with a expandable/contractible portion capable of being elastically expanded or contracted in the predetermined direction. Irrespective of the displacement of the steering gear box, the annular seal is maintained in an elastic pressure contact against the circumferential portion of the aperture of the instrument panel by a reaction force of the compressed expandable/contractible portion.
