In addition, when the rotor or the like and the braking body rotate forward integrally, the outer ring having a cylindrical inner peripheral surface only idles with respect to the inner ring and the rolling member in the body-type rolling type one-way clutch. In addition, no noise is generated when the inner ring comes into contact with the cam member, and the centrifugal force caused by the rotation of the rotor and the like causes the rolling member and the inner peripheral surface of the outer ring to rub against each other so that no sliding noise is generated.

According to the third aspect of the present invention, when the operating member is operated in the direction of braking the reverse rotation of the brake body, the operation is transmitted to the switching member via the connecting member, and the rolling type one-way clutch for connecting the main body is reversely rotated. It is forcibly switched to stop OFF. Therefore, a rolling die for connecting the main body is used when a fishing line is used, a thread is attached to a rod, a tackle is moved, a fishing tackle is baited and a fishing line is thrown, or a fishing line is waiting. The direction clutch stops reverse rotation O
Even if it has been switched to N, when the operating member is operated by a series of reversing operations for the Atari sensing, the rolling connection type one-way clutch for body connection is switched to the reverse rotation stop OFF at the same time as the operation, and thereafter the operating member is operated. The reverse rotation braking of the rotor in accordance with the operation of (1) becomes possible. Therefore, trouble caused by forgetting to switch the rolling type one-way clutch for connecting the main body is prevented.
