Abstract:
A tape cartridge is provided having an improved fit between a reel hole and a drive shaft of a drive. A reel hole that fits with a drive shaft provided in a drive for rotationally driving a reel is formed in the reel. The drive shaft includes a fitting shaft that fits with the reel hole and a guide shaft that enters the reel hole before the fitting shaft and has an outer dimension increasing toward the fitting shaft. A chamfered portion is formed so as to surround the outer periphery of the reel hole.

When the reel hole is viewed from a side facing an opening portion of the reel hole, a portion of the reel hole that fits with the fitting shaft has a polygonal shape, and the inclined face contains a portion in which the width of the inclined face varies along an edge of the polygonal shape.
