ABSTRACT:
Disclosed is a flexible magnetic disk driving device wherein a transmission member which may be bent at an obtuse angle in the intermediate part thereof is pivotally mounted between an operation part and a hub mounting position of a pivoting arm pivotably mounted on a main body, and one end of the transmission member is engaged with a hub shaft while the other end is adapted to be able to contact with a stepped part of a front plate in order to allow a hub to be kept parallel to a spindle even when the operation part is in an open state. Thereby, there is little possibility that the magnetic disk may be damaged when loaded or unloaded and it can be used for a longer period of time, because the hub clamps the magnetic disk with the spindle while remaining substantially parallel to the spindle.
