The upper column includes a clamp that is externally slidably fitted to the lower column and that has a slit extending in the first direction, and a cylindrical part that has a cylindrical shape and that has one end continuous with the clamp and the other end blocked by the bearing being internally fitted. The cylindrical part has an air hole that is spaced apart from the one end of the cylindrical part and that penetrates an outer peripheral surface and an inner peripheral surface of the cylindrical part.
