Abstract
A reel shaft/reel hub fitting apparatus for fitting a reel hub of a tape cassette and reel shaft of a magnetic recording tape running apparatus comprises at least one engaging projection mounted on the outer circumferential surface of the reel shaft and having two side faces which edge away from each other along the circumferential direction as the side faces extend in the direction in which the reel shaft is fitted in said reel hub, walls formed on the reel hub and engaging the reel shaft along the axis of rotation thereof when the reel hub is fitted on the reel shaft, thereby defining the position of the reel hub relative to the reel shaft along the axis of rotation, and at least one engaged projection formed on the inner circumferential surface of the reel hub and located within the locus of rotation of the two side faces of the engaging projection when the position of the reel hub relative to the reel shaft along the axis of rotation is defined by the walls.
