Abstract
An object of the present invention is to provide a fishing reel wherein a bearing rotatably supporting a drive shaft securely shuts out water from its interior so as to maintain stable sealing and thus smooth rotation for a long period wherein such a bearing can be readily built in. In accordance with one aspect, the fishing reel of the present invention includes a drive shaft to be rotationally driven for winding a fishing line around a spool. The drive shaft is rotationally supported by a magnetic fluid sealed bearing having an inner ring magnetic fluid retained between an inner ring and a polar plate retaining a magnet and/or between the inner ring and the magnet, and an outer ring magnetic fluid retained between an outer ring and the polar plate retaining the magnet and/or between the outer ring and the magnet.
