Abstract: A board-like desk member has a planar writing surface and a spaced opposite parallel planar back surface. A fastening device affixed to the back surface of the desk member removably affixes the desk member to the steering wheel of the vehicle in juxtaposition with the steering wheel and parallel to such wheel whereby a person seated behind the wheel may comfortably use the desk member as a desk. A ledge member extends across the desk member and is slidably mounted thereon for movement from top to bottom thereof. A securing device releasably secures the ledge member to a desired position on the writing surface of the desk member.
