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.
