Abstract

PURPOSE:To prevent a tape from flawing and to reduce a noise by providing a plural number of claw members on the circumferential surface of a reel hub engaging member at isometric intervals, making the claw members freely displacible in the radial direction of the reel hub engaging member and allowing the claw members to move outwardly in the radial direction by a centrifugal force at the time of high speed revolution. CONSTITUTION:A reel base 1 is axially supported by a reel base shaft 4 and driven by a reel base driving means. A reel hub 23 is driven by engaging the plural number of the claw members 12 provided on the reel hub engaging member 10 of the reel base 1 with the plural number of recessed parts 25 formed in a center hole of the reel hub 23. The claw members 12 is freely displacible in the radial direction of the reel hub engaging member 10, and usually regulated by an elastic force of an elastic member 14 in the direction of the center axis of the reel base 1. When a magnetic tape 26 is traveling at high speed, i.e., the reel base is revolving at high speed, the claw members 12 are displaced outwardly in the radial direction of the reel hub engaging member 10 by the centrifugal force against the elastic force of the elastic member 14, so as to hold the inner circumferential wall of the center hole of the reel hub 23 by a pressing force. By this method, the tape can be prevented from flawing and the noise reduction can be contrived.
