Abstract
An arrangement for a reverse rotation preventive device for a fishing reel. A hollow engagement member, which is a part of a rotor, is non-rotatively fitted on a drive shaft having an oblong cross-section. A bearing and a hollow collar are simply fitted on the drive shaft. The hollow collar and the hollow engagement member are formed with engagement portions through which they are non-rotatively coupled together. A one-way clutch is arranged so that an outer race member is fixed to a main body and a roller is located between the collar and the outer race member to provide a reverse rotation preventive function when the drive shaft is rotated reversely. By coupling the collar, which is formed into a simple configuration and contacts with the roller, to the engagement member non-rotatively fitted on the drive shaft, it is possible to maintain the dimensional accuracy and high-performance of the rolling-type one-way clutch utilizing wedge action.
