PURPOSE:To deliver accurate rotation of a drive reel shaft to a spool, by providing a self-aligning bearing which absorbs a relative eccentric rotation or cross rotation between the drive reel shaft and an interlocked shaft, for a spool interlocked shaft. CONSTITUTION:A spool interlock shaft 32 directly or indirectly with a spool wound with a magnetic tape T possible for winding or rewinding in a cassette K is provided with self-aligning bearings 4, 5 which are fitted with a drive reel shaft D of a tape recorder with cooperation and absorb relative eccentric rotation and/or cross rotating between the drive reel shaft D and the inter- lock shaft 32. The self-aligning bearings 4, 5 are provided freely slidably toward crossing direction by taking, e.g., the spool shaft or the shaft 32 as a center, or taking the crossing direction of the spool interlocking shaft 32 as each axis. For example, the self-aligning bearings 4, 5 are provided as shown in figure for a long time video recording/reproduction VTR cassette incorporating the 1st and 2nd cases 6, 9. |
