  • Patent number: 9737061
    Abstract: A clutch mechanism includes a clutch portion and a pinion gear. The pinion gear has an engaging part and a gear part. The engaging part is located on a first end as a spool-side end of the pinion gear and is capable of being engaged with the clutch portion. The gear part is meshed with the drive gear. The gear part has helical teeth enabling the pinion gear to be urged toward the spool by the drive gear. The engaging part has a bottom and a first wall. The first wall extends from the bottom toward the first end and tilts in the same direction as the helical teeth with respect to the spool shaft such that the pinion gear is urged oppositely to the spool by the clutch portion when the engaging part is engaged with the clutch portion and receives transmission of rotation in a fishing-line releasing direction from the spool.

    Abstract: A clutch mechanism includes a clutch pin, a pinion gear, a first bearing, a second bearing and a clearance adjusting part. The pinion gear is axially movable to an on-position that causes the pinion gear to engage with the clutch pin and be unitarily rotatable with the spool shaft and an off-position that causes the pinion gear to disengage from the clutch pin. The first bearing is disposed on an outer peripheral surface of a first support part of the pinion gear. The second bearing is disposed on an outer peripheral surface of a second support part of the pinion gear. The clearance adjusting part is configured to partially reduce a clearance between an inner peripheral surface of a through hole and the outer peripheral surface of the spool shaft at the clearance adjusting part in an on-state of the clutch mechanism.
