Abstract
A mode switching over gear mechanism for reel according to this invention is characterized in that a reel brake is disposed at the outside of the fast forward gear and the rewinding gear, respectively; a preload brake is disposed at the inside of the fast forward gear and the rewinding gear, respectively; and the control of the preload brake is effected by the same member as the control of the take-up gear effecting the mode switching over at the play, which member is different from the member for the control of the reel brake. Owing to this construction, since the preload brake is released at the same time as the mode switching over by the engagement of the take-up gear, no infructuous load is applied thereto.
